Description

Device for registering movement of a joint
The invention relates to a device for registering movement of a joint, the device being adapted to be secured as separate part to a predetermined body part and containing an inclinometer sensor based on gravitational force, data about the joint movement being registrable in the device with the help of the measurements of the inclinometer sensor.
The rehabilitation of joints after an injury or an operation is based on restoring the extension of movement of the joint and at the same time on maintaining the muscle power. Because of the extent of the injury or the taken measure it is appropriate in most cases to restrict the mobility of the joint at the beginning by means of a plaster cast, splint or the like, and simultaneously maintain the muscle power with isometric exercises. This results regularly in stiffening of the joint and in decrease in muscle power. The so called hinged plasters and hinged splints are intended to allow the preservation of a certain path of movement with the help of mechanical restrictors. This extension of movement will be increased as the rehabilitation proceeds.
For example the repair operation of an injury in the front cruciate ligament of the knee is nowadays based on the use of a tendon transplant taken out from the knee tendon. As the knee is stretched below a bending angle of 30° and on the other hand as it is bent over a bending angle of 60°, the transplant is subjected to a tensile stress, which before the fixation of the transplant brings about stretching of the transplant and loss of the joint stability, that is, failure of the operation. After the operation the knee is usually made stiff at an angle of 45° for a week and thereafter a movement between 30° and 60° is allowed during the following two weeks. During the last three weeks a movement from 0 to 90° is allowed. After the removal of the hinged joint, the phase of an active rehabilitation lasting 6 to 12 weeks is started in view of restoring the rest of the path of movement. The duration of this phase depends greatly on the patient himself. A similar principle is applied in the aftertreatment of the injuries of other joints and bones as well.
Insufficent possibilities to control the advancement of the rehabilitation must be regarded as the most severe drawback of the methods in use today, that is, to control if the patient is acting according to the orders given. Even if the splint has mechanical adjustable restrictors, it does by no means guarantee that the extension of movement is exercised within the whole allowed path of movement. On the other hand, several adjusting occasions consume, in addition to policlinic resources of the hospitals, considerably also other services of the society and time of the patient. The rehabilitation programs must be established on the basis of the afore-mentioned weekly programmes. However, the rehabilitation is a continuum that develops every day.
From the publication WO 87/05229 is known an idea of a device that can be placed on a wrist and that can count the number of strokes of a swimmer by means of a sensor that is included therein and is based on gravitational force. The device is not applicable to the monitoring of the rehabilitation.
The object of the invention is to effect a decisive improvement as far as the afore-mentioned drawbacks are concerned. For achieving this goal the device according to the invention is characterized by what is disclosed in the characterizing portion of claim 1. By means of the device, several advantages are achieved in the rehabilitation. A predefined, variable rehabilitation program stored in the device enables individual, active and independent rehabilitation. The data of the rehabilitation performance that has been collected by the device can be unpacked afterwards and the fulfilment of the rehabilitation program can be controlled in this way. By virtue of the device the need to visit the policlinic will be diminished, because all essential information is stored in the memory of the device.
The invention makes it possible to remove the plaster cast or splint earlier than before and the return to a normal life can take place sooner. The treatment of the injury does not limit the activities or work of the patient more than the injury itself. The rehabilitation performance is hence not bound to a specific time, place nor to the chosen method of treatment.
The invention will be described in the following more closely with the reference to the accompanying drawings, where
Fig. 1 shows the device in perspective,
Fig. 2 shows the coupling of the device to an external computer,
Fig. 3 illustrates the use of the device in the rehabilitation,
Fig. 4 illustrates the storing principle of the measurement data, and
Fig. 5 is an example of the data contained in the device. The device 1 comprises a box that is adapted to be secured as separate part to a predetermined body part, for example by means of a strap 3. The device contains an inclinometer sensor based on gravitational force and being capable of measuring the angular positions of the device. The inclinometer sensor can be any commonly used sensor, for example a potentiometer, and the device contains memory space for registering the measurement data of the inclinometer sensor. The casing of the box can be for example of plastics.
The device can be applied to the rehabilitation as follows:
A doctor or any other person supervising the rehabilitation enters the rehabilitation program to the memory space of the device, according to Fig. 2 for example with a PC 6, for which purpose the device 1 has a connector 2 for a cable 7 intended for the input of the information and connected to the PC. The input information can be the following:
a sign for the day or another time period of a predetermined length the extension of movement in the form of the width of the angle or the angle values of the extreme positions the number of repetitions corresponding to this movement during the time period concerned.
Every day or time period of a predetermined length can thus be assigned a predetermined number of repetitions and the extension of the movements to be performed can be defined.
The data accumulated in the device can be unpacked through the same connector 2. As shown in Fig. 3, the device can be used in the rehabilitation of a knee joint. The user can secure the device 1 to the lower part of the leg with the strap 3. This device containing the predetermined rehabilitation program is now ready for performing the rehabilitation program. For determining a certain zero angle the device contains a push button 4 (Fig. 1) , by means of which an angle corresponding to a certain position of the sensor is determined as zero. The push button can be also an external one that is connectable to the device through a cable. This calibration is carried out for example when the knee is at an angle of 90° and the leg stands in vertical position. When the leg is now bent to both sides of the above-mentioned position within the limits allowed by the mobility of the knee joint, the device will register angle values α and β corresponding to the extreme positions. The device calculates during the movement the maximum angles in relation to the zero angle that are measured by the sensor. The device counts also the number of the repetitions. After a certain time, for example after 4 to 6 weeks, the information stored in the device can be unpacked therefrom, that is, the angle values and the number of repetitions for every day. The information is stored preferably in such a way that the number of the repetitions that have fulfilled the desired angle values of the exercise program will be seen in connection with every day or other time period. The device can store the angle values of all repetitions for example by orders of magnitude to save the memory space and to improve the readability of the results. The repetitions can be stored in classified form for example at the intervals of 10°, 5°, or at any angular intervals suitable for the purpose. This has been illustrated in Fig. 4 where the angular range of movement of the joint is divided into areas A - B at the intervals of 10°. So that the user of the device could himself follow the realization of the rehabilitation program, the device can have a suitable signalling means, such as a sound emitter that informs, when an angular position set in the device (for example the extreme position of a knee joint) has been attained, and it can further give a signal of another type, when the required number of repetitions fulfilling a certain extension of movement has been performed during a predetermined time period, for example during a certain day. In order to follow the fulfilling of the rehabilitation program in different days the device must also have an internal clock. The device can also have a display 5 (Fig. 1) , which shows the measuring data of the inclinometer sensor and other information, such as operator's manual and commands during the use to give information to the user concerning the readiness, calibration, measuring operation etc.
The following parts can be incoporated in the box of the device 1 to perform the afore-mentioned functions:
an electric sensor based on gravitational force and a sensor amplifier, which give a current or voltage signal corresponding to the angular position of the box
- A/D converter for converting the above-mentioned electrical signal into digital form - a processor for processing the data in the digital form
- a variable memory for storing the data calculated by the processor and the data of the rehabilitation program entered into the device - a fixed write memory for performing the program controlling the operational principles of the device
- a circuit for realizing an external data communication connection a clock circuit or a timer for maintaining the calender of the rehabilitation program - a current source, such as a battery or rechargeable battery.
All above-mentioned parts can be joined together by principles that are commonly known and can be carried into effect by a man skilled in the art. Further, some functional parts can be situated on the same microchip.
The device can include also the above-mentioned display and display controller. The device can also include in addition to the push button 4 or in place of it, a connector 8 (Fig. 1) for a push button that can be connected to the device through a cable. This is preferable in the case where the device 1 is secured in such a place that the push button 4 on its side is not easily accessible to the user.
Further, the device can comprise the above-mentioned signalling means, by means of which the user can detect during the repetition that he has reached a certain angular range that has been set as the goal. The signalling means can give also a signal of another type when a sufficent number of the repetitions fulfilling the goals have been performed or the number of the performed, repetitions is in general the same as the number that has been assigned to the period.
Fig. 5 shows further the information obtainable from the device after a certain rehabilitation period. The information that again can be unpacked by a PC according to the principle of Fig. 2 is in an easily readable form, because they are grouped according to the angular ranges (the signs of the angular ranges are the same as in Fig. 4) and it does not contain absolute angle values. It is thereby possible to detect at once, to which extent the rehabilitation program is fulfilled by seeing, how many repetitions has been performed in each day or within any other time period monitored by the clock circuit or timer of the device, and by seeing their distribution in numbers in various ranges. This saves also the memory space of the device. The table of Fig. 5 is intended solely as an example and the information can be presented also in another form.
The invention is not restricted to the above-mentioned example, but it can be varied within the inventional idea represented by the accompanying claims. Hence, the device can be used for the rehabilitation of any joint, muscle or muscle group, the rehabilitation program of which contains a predetermined number of repetitions extending to a predetermined angular range. The device can be secured for example to the lower end of a forearm in the case of some rehabilitation of arm joints or muscles.
