Definitions

  • the invention relates to exercise devices suitable for the rehabilitation of patients following traumatic joint injury or wound care but also for sports physiotherapy and general exercise. More specifically, the invention relates to an intelligent device that allows a selection of exercise programs to be monitored.
  • the devices of this invention show that the position and angle of the users limbs, and / or the kinesthesia of the users limbs may allow the therapists a better understanding of condition of the limb of the user.
  • proprioceptive / neuromuscular rehabilitation this may allow the therapist a better understanding of the progression of a patients rehabilitation, whether the patient is progressing at the desired rate and whether the exercise program is suitable to the patient or if it is not to change the exercise program.
  • this can offer benefits to the therapist working with sports men and women.
  • Previous physiotherapy equipment and treatment systems needed close supervision by the therapist to ensure that the exercises were being carried out correctly and indeed to ensure that the patient was doing the exercises.
  • the therapist for the prior art rehabilitation systems had to be present when the user was being assessed.
  • the present invention is able to address these problems of the prior art by assimilating quantitative and qualitative data that can be communicated to the therapist for interpreting that will accurately indicate the progress of the patient performing the exercise programme. It was previously thought that the therapist would always have to be present at the time of the exercises as any data collected from the exercises could not interpreted to indicate the progress of the patient performing the exercise programme. Surprisingly we have found that this is not true.
  • an exercise device comprising; a lamina with a sensor for sensing contact, and/or position on, or adjacent the lamina; and a processor for processing outputs from the contact, and or position sensor.
  • the position sensor will be able to sense where a user's limb is adjacent to the lamina, even if not in contact with the lamina.
  • the contact sensor can also measure pressure or the force exerted on the lamina.
  • lamina is to include any substantially flat surface suitable to act as a target for the user's movement. This will include but not be limited to mats, rugs and the like.
  • the device of the present invention whether it comprises a contact sensor, a position sensor or both may also comprise a memory database to store the processed data generated so that this data can be downloaded or examined by the user or therapist at a later time.
  • the device of the present invention whether it comprises a contact sensor, a position sensor or both also comprise a message conveyor to instruct the user to perform a predetermined exercise programme.
  • the device of the present invention may therefore comprise of a number of different added components.
  • the present invention in a simple form may comprise of only one sensor, a contact sensor or a position sensor, and a processor.
  • the present invention may also include devices that have a contact sensor, a position sensor, a pressure sensor, a processor, a memory database and a message conveyor, or any combination thereof.
  • an exercise device having; a mat with pressure sensitive means for sensing contact on the mat and which is able to detect the position of contact on the mat; and a control means connected with the pressure sensitive means for receiving outputs from the pressure sensitive means, the control means further including programmed processing means for processing outputs from the pressure sensing means and memory means for retaining the processed data outputs from the pressure sensing means, the control means further having means to instruct a user to perform a predetermined exercise program.
  • the pressure sensitive means is also able to measure the amount of pressure or force applied to the mat. In some favoured embodiments of the present invention this is useful for determining the centre of gravity of the patient.
  • an exercise device having; a mat with pressure sensitive means for sensing contact on the mat and which is able to detect the position of contact on the mat, and the amount of pressure or force applied to the mat; and a control means connected with the pressure sensitive means for receiving outputs from the pressure sensitive means; the control means further including programmed processing means for processing outputs from the pressure sensing means and memory means for retaining the processed data outputs from the pressure sensing means; the control means further having means to instruct a user to perform a predetermined exercise program.
  • the present invention can be small enough to be easily transportable and therefore the exercise routine need not necessarily be performed at the therapist's clinic.
  • the term therapist is used broadly to mean anyone overseeing the exercise programme or the rehabilitation of the user and this would include, but be limited to, physiotherapists and occupational-therapists.
  • the device may have means to convey instructions of the exercise programme to the user and has means to monitor and record the users performance, it is again not necessary to use the device in the therapists clinic only.
  • the user can save considerable time by not having to visit the therapist as often and can more easily fit the required exercise program into his or hers daily routine. Being able to do the required exercises in private may also be a favourable consideration to some users and thus the user's compliance for doing the exercises may in fact increase when not in the presence of the therapist. This may be especially true when the device is for rehabilitation of elderly patients.
  • the therapist also saves considerable time as data from the device can be collated some time after the exercises have been done and can be sent to the therapists for analysing or can be down loaded to a data collecting station at a mutually convenient time.
  • the therapists will however still be able to monitor closely the user's compliance of carrying out the exercise and to determine if the exercises are having the desired effect.
  • the monitoring however can be done remotely and does not require the therapist to be present when the exercises are being performed.
  • the therapist can alter the predetermined exercise program of the device in order to ensure that the user does have an exercise program suitable to their particular needs. Again this can be done remotely.
  • the present invention provides an easy means to store and analyse the users current and past exercise data to aid the therapist to monitor the progress of the user and therefore to be able to change the exercise program accordingly. There is therefore an opportunity for the user to have a speedier recovery, saving time and money for both the user and the therapist.
  • the level of feedback to the therapist is determined by how the information will be used. Firstly, the data must be a substitute for clinical observations, which would normally be made by the therapist. The therapist must therefore have sufficient depth of information to allow clinical judgements to be made, and to progress the rehabilitation programme. For example, it is necessary for the therapist to know if the patient can bear weight through an operated knee. It is proposed that data supplied to the therapist will act not only as substitute clinical observations, but will also be capable of providing accurate measurements of how much weight is transferred through the knee, for what duration of time, over what range of motion and for how many repetitions of a specific movement/ exercise. An indication of proprioceptive integrity will also be given by the number of errors in performing a defined task. This data will be available as raw numerical records, but may also be presented in a more accessible way, for example as a bar chart, histogram, graph or percentages. These presentation styles should be available to the user through a menu.
  • Incidences the number of times the device was used, repetitions of an exercise/movement, touchdowns during a single leg stance, steps taken (in a weight bearing exercise), movement limitation alerts.
  • the lamina e.g. mat can be positioned to be suitable to detect contact with various limbs of the users body.
  • the user will have an exercise program that requires the user to move either a hand or foot, or any other suitable part of the body, to a desired position on the mat.
  • These programs may specify whether it is the left or right, hand or foot.
  • the mat may preferably be positioned on the floor.
  • the lamina e.g. mat may be preferably placed on the floor. Where the exercises require the user to move the hand to various target positions, the lamina e.g.
  • the lamina e.g. mat may suitably be placed on a table or on a wall or other vertical surface to allow easy positioning of the users hand on the lamina e.g. mat.
  • the lamina e.g. mat may also be suitably placed on a table or held vertically. Suitable means of attaching the lamina e.g. mat to a wall or vertical surface could be used to position the lamina e.g. mat.
  • the lamina e.g. mat need not be restricted to substantially flat surfaces for it is envisaged that the lamina e.g. mat could be used on uneven surfaces in order to test a users balance and / or movement on an uneven surface.
  • Suitable attachment means to attach the lamina e.g. mat, securely to the stairs would be preferably used in conjunction with the mat in order to ensure safe usage of the mat by the user.
  • the lamina e.g. mat may also have different textured surfaces for the user to perform the exercises on. This may be where there is different textured surfaces for different exercise programs or where the lamina e.g. mat is made up of different textured surfaces the same exercise program.
  • the lamina e.g. mat may also be used on soft surfaces.
  • the lamina e.g. mat may be used on an exercise bouncer.
  • the lamina e.g. mat may be of any size or shape however it is envisaged that a mat of approximately 1 m to 2 m by 1 m to 2m would be preferable to allow for easy transportation of the device. It is envisaged that a smaller lamina e.g. mat could be used for upper body exercises, for instance 1m by 1m, and a larger lamina e.g. mat, for instance 3m by 3m, for exercises directed at mainly the lower body. Typically the lamina e.g. mat would be 1 m by 2m for exercises directed mainly for the upper body, and typically 2.5m by 1.5m for exercises directed mainly for the lower body.
  • the particular mat need not be limited for any particular program of exercise and it is envisaged that the one mat could be used for exercises directed at both, the upper and lower, body of the user.
  • the lamina e.g. mat in some embodiments of the present invention may be easily rolled or folded to facilitate storage.
  • the lamina e.g. mat of the present invention may be formed from a number of parts, which together make up the device.
  • the number of contact, position and/or pressure sensors may change and there is not necessarily a set number of such sensors required.
  • the parts for example the sensors, will join together easily and quickly to aid easy setting up of the device. In this way the number of sensors used for the exercise programme can be easily altered.
  • the parts of the device may communicate with each other by radio means and therefore the parts making up the invention need not physically be in connected with each other.
  • the lamina e.g. mat can be made of any suitable material.
  • the lamina, e.g. mat will be an elastic material or fabric.
  • the mat may be a 3D fabric whereby the pressure sensitive means contain two rows of metallic strips that run perpendicular to each other and when pressure is applied to the mat the two rows of metallic strips come into contact with each other at the point of the applied pressure thereby indicating where the pressure on the mat has taken place.
  • Another embodiment of the present invention may contain a mat having a series of individual air pockets, which are the targets for the user to hit. On applying pressure to the air pocket, air is pushed through a valve whereby the control means of the device can record which air pocket was hit and when.
  • the lamina e.g. mat of the present invention would use a contact sensing means using capacitance to detect contact.
  • a capacitance sensing mat uses a single plate and senses the presence of the body or limb.
  • the device has no moving parts and hence is may be very robust. Also with no moving parts the sensing element can be very flexible.
  • the electronics detect a change in capacitance at the isolated pad, which can be any shape or size. Separate circuitry can be used for each pad although if a number of pads are to be used it is possible to multiplex the signals from the pads.
  • the capacitance mat may be supplied with all its pads in place together or may be supplied in parts so that a number of different pads could be used and that the pads can be assembled together to form mats of different shapes.
  • the sensing pads of the capacitance sensing mat may each have an identifying electrical component such that the processor can identify each pad being used to make up the mat. Therefore when the pads are put together in the correct predetermined order the correct data processing can take place. In this way the processor can identify if the exercise was performed correctly or not.
  • the sensor that make up the lamina e.g. mat may communicate with each other and the processor by radio means such that the sensors do not have to be physically connected to each other or to the sensor, by cables, wires and the like.
  • capacitance sensors in this way, as for large foot size pads, is new, previously only very small capacitance sensors have been used and it was previously thought that the capacitance sensors had to be small due to the possibility of electronic interference.
  • the present invention has now demonstrated that large capacitance sensors can be used to accurately detect contact without electronic interference, even when a user of the mat is moving above the mat surface as when performing the exercise programme.
  • the present invention has also found that the use of screens around the sensor plate further reduces electronic interference, enabling the capacitance sensors to be successfully used as large contact sensors for the performing exercises.
  • the mat of the present invention may also measure the amount of pressure applied to various points of the mat, not just if contact is made. This may provide useful information to the therapist in order for the therapist to assess if the exercise program is, among other things, helping the user.
  • the means to measure the pressure applied to the mat may be any means suitable for such purpose and there are currently a number of different methods known for measuring pressure and force. In the majority of cases a force reading is taken over a given cross-sectional area and hence is recording a pressure.
  • the measurement of pressure in a clinical environment is normally required in order to determine the patient's load bearing.
  • the mat has a flexible fluid chamber, suitably shaped to cover the area of the mat and having first and second opposed walls.
  • the flexible fluid chamber would be without internal elements that would hold the first and second walls apart, but would possibly be subdivided into smaller fluid filled chambers.
  • the chamber would also have means for providing a fluid communication between said chamber and a pressure, sensing device. When pressure is exerted on the chamber, for instance, when a foot is lowered onto the mat the fluid in the chamber would be forced towards the pressure sensitive device, which would be able to measure the force and this force could be calibrated to measure the force on the mat.
  • the force sensing means can take the form of a force, sensing resistor (FSR) as supplied by Steadlands International Marketing Ltd.,
  • the FSR consists of two polymer sheets laminated together. One sheet is coated with interdigitating electrodes top a greater or lesser degree. By measuring the resistance the force can be recorded. The sensor takes measurements in the first 20 seconds of loading and then an average of these readings is taken.
  • a pressure-indicating film as supplied by Fuji (Pressure (R)).
  • the film records the pressure distribution according to colours; the more intense the colour, the greater the pressure.
  • the films are single use and would be mounted on the reverse side of the mat.
  • a colour scale would be provided to the clinician.
  • the therapist will ask the patient to stand on two tiles of the mat and stand normally with equal load through both limbs. Once the patient moves off the tiles, the therapist can compare the pressures recorded for the involved and uninvolved limbs by eye.
  • the mechanics of the exercises are qualitative and this is an improvement on current practice where a patient is asked to stand on a therapists hand in order for the therapist to judge the loading.
  • the mat will have markings to act as specific targets for the user to make contact with the mat when directed to do so for the particular exercise program.
  • This could be simply a series of labelled or indexed grids on the mat.
  • the grids on the mat could be of different sizes and therefore suitable for a wider range of exercise programs.
  • the grids will be coloured coded in order to allow easy visual differentiation between the grids.
  • the grid spacing will enable desired targets to be large enough for the users hand or foot to be placed substantially over the target area.
  • the pressure sensitive mat may not necessarily have the marking directly on the mat but the mat could be used in conjunction with a target cover that is to be placed over the pressure sensitive mat.
  • the target cover may be like a sheath to cover all or part of the mat and it is the target cover that has the markings to act as targets for the user.
  • the grid spacing will enable desired target areas to be large enough for the user's hand or foot, or other body limb, to be placed substantially over the target area.
  • the mat may even contain lights on the surface of the mat in embodiments of the present invention where the lights themselves are the target for which the user should place their hand or foot on when that particular light lights up.
  • the lights would suitably be protected from the physical contact of the user putting pressure on the surface of the mat. It would also be preferable with this embodiment of the present invention if the lights could be contained within the substantially flat surface of the mat or cover target so that the surface is still substantially flat. Having the surface substantially flat is important where the user is walking on the mat and may be tripped by the lights if the lights projected from the surface.
  • control means will be able to collect and store the data in order to be able to later download the collected data.
  • the downloading of the collected data may be done by the therapist, either at the clinic or elsewhere or the data could be downloaded by the user and sent to the therapist for analysing. It is possible, using suitable means that the collected data could be sent to the therapist by telephone, e.g. e-mail, or radio. It is even possible that the collected data could be sent to a collecting station near to the therapist or at the clinic to enable the therapist to analyse the data when required.
  • the predetermined exercise program of the device may be pre-programmed into the device by the therapist.
  • exercise programs There is no limitation to what exercise programs could be programmed into the device, in order for the user to carry out the exercise program.
  • the therapist would preferably choose an exercise program that would be challenging to the user but still within their capabilities.
  • the exercise programs may consist entirely of simple commands, for instance to move the left foot to grid H or to move the right hand to square 5, if such grid or square locations were represented on the mat.
  • the commands may be any number of different command including commands to ask the user to jump, hop, hit, kick, run or push.
  • Common exercises for the user to perform with the present invention may be single leg stances. These are relatively static exercises, which are widely used in the early stages of rehabilitation to test and improve proprioceptive ability.
  • the user would stand in a specified position on the mat and may be requested to lift their uninvolved leg so that they are standing on their injured leg.
  • the mat will record how long the user can maintain this position or how many touchdowns the user made in a set time.
  • lunges are a widely used exercise that may vary from easy forward lunges close to the starting position to difficult long lunges diagonally across the body. Each lunge is done from the same starting position and this starting position should be returned to before the exercises can progress.
  • a further exercise, which may be performed with the present invention are various hopping patterns. Perhaps used in the later stages of rehabilitation, the mat may provide targets for the patient to hop to. This exercise incorporates general agility, response time, and perturbation of balance due to rapid changes of direction.
  • the device may record where the errors occur, how many errors, how the errors occur, how quickly a pattern can be completed.
  • Further exercises which may be performed on the mat of the present invention further include but are not limited to, front and side lunges; stork stances; Romberg test; side step over perturbation training; plyometric training and stretching drills; and running.
  • the instructions or commands of what movement the user is required to do can be conveyed to the user by any suitable means.
  • the means to convey instructions or commands to the user need not necessarily be attached to the control unit as the means to convey instructions or commands to the user may be in wireless communication with it. This may be by instructions on a TV or LCD screen that the user can look at whilst performing the exercise programme.
  • the display on the screen may be by any suitable means but would typically be written instructions or a graphic display of what the instructions are.
  • the instructions may also be conveyed to the user by other visual means for example when lights are used within the mat to move to the light, which is switched on or off as the case may be. Additionally the device may incorporate a light projecting means on to the mat where the user must move to where the light projection falls onto the mat.
  • the instructions could be by simple audio means i.e. audio- tape or digitised voice.
  • the instructions to the user in order to perform the exercise program may be written on a sheet of paper. Once the device has indicated to the user to start the exercises, for instance, this may be to show that the control unit is switched on and is ready to monitor and record the exercises. Suitably, the user may perform the exercises as written on the sheet of paper.
  • the feedback system may have the following stages:
  • Improvement indicates that the prescribed instruction/exercise has been successfully performed with an improvement on the previous recorded attempt. It could be repeating bell sound or flashing green light. This is designed to motivate the user.
  • Miss - indicates that the instruction/exercise has not been performed correctly. It could be a negative sound e.g. low pitch buzz, or red light. It should be followed by a restart command and the Start indication of the correct neutral starting position. The purpose of this would be to prevent incorrect movements, which might be deleterious and thus give confidence to the user.
  • Alert - this would be used for users who are required to learn limitations to their movements. Examples are learning correct posture for back patients, learning correct lifting technique, preventing uneven weight-bearing, avoiding hip dislocation after hip replacement, and avoiding over-extension following TKR.
  • the purpose would be to indicate to the user that they were approaching their maximum permitted ROM and therefore prevent potentially deleterious movements.
  • the indicator could be an amber light, a low level beep or a vibration. This would prevent re-injury, accelerate healing and give the patient a sense of control and confidence.
  • Performance level - for users who are highly motivated e.g. athletes and sports people, and who are determined to reach a high level of fitness, it is possible the hits, misses and improvements could be indicated as a bar chart or percentage. The number of repetitions of an activity could, also be displayed by a simple counter. This would provide motivation as well as a sense of control.
  • the present invention should be designed so that command signals are not confused with feedback indicators.
  • the device of the present invention will suitability also have means to convey information regarding the exercises performed by the user to the therapist. In this way the physiotherapist will be able to monitor the progress of the user without needing to actually see the user. It is envisaged that any suitable means to convey this information from the device to the physiotherapist may be used. These means may include a smart card, which would collect the exercise performance data from the device and then this smart card could be taken or sent to the therapist. The device may also have a telephone modem in order to send the data to the therapist's office. This may be at set times picked by the programmed device itself or when requested by the user or therapist.
  • the device of the present invention could also be used in the therapists clinic, or in the presence of the therapist, and this may enable the therapist to monitor the user more quickly than in the past or more efficiently than in the past.
  • the device may already have programmed into it an alerting system which when the exercises have been performed a set number of times, at a set efficiency, the user, or th ⁇ rapist, is alerted to download the information.
  • the data may be printed out for sending to the therapist or the device itself may be returned to the therapist.

  • the third layer ( Figure 6) as mentioned has the Earth Screen (7), which is larger than the sensor (5) and guard plate (8) and measures 205 mm by 205 mm. This acts to prevent electrical interference with sensor for example from the floor direction.

  • the above described layers make up a capacitance contact sensor such that the body part or limb completes the capacitor and the sensor detects the electrical difference between the guard plate and the body part of the user.
  • the capacitance sensor can therefore detect the presence or absence of contact of the user.
  • the capacitance sensor will be able to give different reading values of the capacitance detected.
  • the screen surrounding the sensor acts to protect the sensor against electronic interference or from measuring the capacitance between the guard plate and the body part of the user when the user is only near to this particular pad i.e. when the user is standing on an adjacent pad or simply moving over the pad.
  • the layers are stuck together using an adhesive.
  • the exercise file or computer program is a text file and is loaded into the PC, the computer program of this example is of an exercise programme for the legs.
  • the programme is set to ask if the user will move one or both feet, by asking if there is a base square. This would be the square from which the patent does not move his good leg during exercise. If both feet are to be moved then there is no base square and "0" is entered.
  • the mat programme behaviour can be modified by adding single letters after the mat number e.g. a "b" indicates that the mat is a base square and is only valid on the first line of the exercise file, a "c" indicates that the patient must move to the mat correctly before the next target is displayed. For a lunge exercise for a patient exercising his left leg, with his right leg being healthy and not requiring exercising the programme may run.

  • "Iunge017.txt” contains results referring to the seventeenth time that the lunge exercise programme has been carried out.
  • the files can be read by almost any word processor.
  • a typical lunge results file is as in this example:
  • a mat and apparatus as described in example 4 is used to perform the hop exercises. These exercises can be used to exercise either leg, however the exercise file may need to be altered so that the patient makes more hops in the directions recommended by the therapist.
  • Stepping from square to square would not be spotted until contact on two non-adjacent squares was detected. Both contacts would be recorded and entered in the results file.
  • a mat as described in example 4 was used for balance type exercises.
  • the object of the balance exercise file in this instance is to test the stability and strength of the patient's right leg.
  • the same exercise could test the left leg by standing on the mat and facing the other way.
  • the difficulty with timing balance is that the patient may be standing on one foot while walking over the mat or getting himself into position. Thus, it is of no use merely to detect when just one foot is touching the mat.
  • the mat time is primed as follows. The patient puts his right foot on the base square (square 1 ) while his left foot is not on square 6. Without moving his right foot, he places his left foot on square 6. The software will start timing his balance duration as soon as he lifts his left foot. The timer will stop as soon as he puts his foot down or leaves (falls off) the base square.
  • the patient when the patient is ready to repeat the balance exercise, he can move a foot to square 2 so that the priming sequence can start. This may be desirable so that the patient is forced to compose himself before repeating the exercise.
  • results may be, as in this example:
