Definitions

  • the present invention relates to an apparatus for training, investigating and re- educating neuro-muscular functions in a subject.
  • Exercise equipment for rehabilitation is at about the same state of advancement as athletic equipment.
  • standard athletics-oriented machines are often used in rehabilitation clinics.
  • their effectiveness is highly limited; largely because they are suitable for only one very specific exercise.
  • Other machines build specifically for rehabilitation is often very costly. This means that only very few specialized rehabilitation units, such as those in hospitals, can afford to acquire these machines. Hence, only few patients receive the benefit of the specialised equipment.
  • the complaints about present exercise machines from hospitals and clinics with rehabilitation facilities, and from doctors who specialize in this field are numerous and significant.
  • One common problem is that most machines use weights to provide the resisting force.
  • the inertia of the weights allows the patient to throw or jerk the device in order to avoid exercising through regions of extreme weakness - precisely the regions where exercise is most needed.
  • Other problems mentioned are lack of fine enough variation of resisting force, lack of adaptation to the patient's size, no allowance for the adjustment of the variation of resisting force with position, and general lack of adaptability to the individual patient's specific needs.
  • Muscular strength is most rapidly developed by using various types of devices and machines, which provide forces to resist movement by the subject. In order to attain a rate of increase of strength and a level of strength greater than those attainable through participation in most sports and other athletic activities, relatively high resisting forces must be used.
  • the most common presently available means for obtaining high-resistance exercise are the pulley-weight machine, the barbell, spring-action devices, and frictional devices, of both mechanical and fluid type.
  • the primary biological mechanism by which muscle fibers are stimulated to grow involves the accumulation of certain biomolecules produced during intense muscular contraction. These biomolecules act as signal transducers sending a signal to the muscle fiber cells resulting in increases in the quantity of the protein-based muscle tissue.
  • Exercise against light resistance has relatively little effect on muscular strength, but, if sustained for sufficiently long periods, it is most effective in increasing muscular endurance.
  • the amount of force that can be exerted by the arms or legs is highly dependent on their position and angular orientation. It depends both on the direction in which force is being exerted and on the angles of the joints. In order to obtain maximum muscular strength throughout the full range of movement, the resisting forces of an exercise must vary according to the individual's strength potential at any given position along the path of motion.
  • the starting and finishing positions of an exercise motion are important. A fully extended starting position is necessary to obtain maximum intensity of muscular contraction during the exercise motion. The longest possible path of motion also allows for increases in flexibility. Due to the large variations in physical dimensions among the subjects, all presently available exercise machines have serious limitations in this respect.
  • the speed at which an exercise is performed is very important. This is because there are two distinct types of muscle fibers which comprise every skeletal muscle.
  • the red, or slow-twitch, fibers provide forces primarily during slow movements.
  • the white, or fast-twitch, fibers can contract only during relatively fast movements, and are used primarily in high-speed activities such as sprinting or swimming. Muscle performance at high speed cannot be improved by low-speed exercise. Nor can low- speed muscle strength be improved significantly by high-speed exercise. For these reasons, an athlete must train selectively for the particular event or activity in which he specializes.
  • isokinetic Exercise done at a fixed speed and with variable resistance is called isokinetic.
  • Conventional exercise machines which use weights to provide the resisting force, are not very well suited for isokinetic exercise. Because weights have inertia, the speed of the exercise will vary greatly throughout the motion, allowing for optimum speeds and resistances only over a short segment of the full range of motion.
  • One aspect relates to an apparatus for training, investigating and re-educating neuro-muscular functions in a subject, the apparatus comprising:
  • a work member for interfacing with a subject to be exercised and comprising a rotary drum on which a cable is wound, said cable having a cable end being adapted for attachment to grasping means for grasping by said subject;
  • grasping means for grasping by said subject
  • a first electronic detector configured to continuously transmit data on the positions associated with the work member and/or with the grasping means
  • the processor is configured to continuously receive the data on the positions associated with the work member and/or with the grasping means; and wherein the processor is configured to instruct the electric motor to change from a cable unwinding operation to a cable rewinding operation, or vice versa, in response to received data from the first electronic detector.
  • Another aspect relates to an apparatus for training, investigating and re-educating neuro-muscular functions in a subject, the apparatus comprising:
  • a work member for interfacing with a subject to be exercised and comprising a rotary drum on which a cable is wound, said cable having a cable end being adapted for attachment to grasping means for grasping by said subject;
  • grasping means for grasping by said subject
  • a first electronic detector configured to continuously transmit data on the positions associated with the work member and/or with the grasping means
  • a third aspect relates to an apparatus for training, investigating and re-educating neuro-muscular functions in a subject, the apparatus comprising:
  • a work member for interfacing with a subject to be exercised and comprising a rotary drum on which a cable is wound, said cable having a cable end being adapted for attachment to grasping means for grasping by said subject;
  • grasping means for grasping by said subject
  • a first electronic detector configured to continuously transmit data on the positions associated with the work member and/or with the grasping means
  • a second electronic detector configured to continuously transmit data on the forces associated with the work member
  • the processor is configured to a) continuously receive the data from the first electronic detector on the positions associated with the work member and/or with the grasping means and b) configured to continuously receive the data from the second electronic detector on the forces associated with the work member; and wherein the processor is configured to instruct the electric motor to change from a cable unwinding operation to a cable rewinding operation, or vice versa, in response to the combination of data received from the first and second electronic detector.
  • the position associated with the work member is estimated using the motor position.
  • the apparatus comprises a work member for interfacing with a subject/subject to be exercised or investigated.
  • the work member comprises a rotary drum on which a cable is wound.
  • the work member may in one or more embodiments comprise attachment means for attaching the rotary drum to a supporting frame.
  • the cable has a cable end being adapted for attachment to grasping means for grasping by said subject.
  • the apparatus may also comprise grasping means for grasping by said subject.
  • the cable end is adapted for attachment to the cable of a weight-training machine. This allows for a nearly complete reuse of the weight-training machine (such as the framework and grasping means), except for the weights. Furthermore, in one or more embodiments, the weights may be retained, such that the subject can switch from normal weight training to training according to the present invention.
  • the cable has a cross-section that is essentially circular. This is an advantage over flat cables, which are more restricted in the working angle towards the rotary drum. When using flat cables, the subject will have to stand in line with the rotary drum when pulling the cable.
  • essentially circular is to be understood broadly and should even include elliptical, oval, and other geometries that vary from a precise circular shape.
  • the cable has a cross-section that is circular.
  • the cable is a static cable as opposed to a dynamic cable (or elastic cable). This is important, as any elasticity will affect the electronic sensors and result in errors in calculation/direct measurement of force and cable position.
  • the apparatus further comprises an electric motor adapted for driving the rotary drum in a cable unwinding and rewinding operation.
  • the electric motor is coupled to a gearbox.
  • the apparatus also comprises a first electronic detector configured to continuously transmit data on the positions associated with the work member and/or with the grasping means. Any type of electronic position detector may be used.
  • the electronic sensor may as an example be configured to calculate the linear distance between the rotary drum and the cable end (adapted for attachment to the cable of a weight-training machine/grasping means) by measuring the number of rotations of the rotary drum.
  • the apparatus further comprises a processor.
  • the processor is configured to continuously receive the data on the positions associated with the work member and/or with the grasping means. This is important, as knowledge of the position of e.g. the cable end is used in many of the operations of the apparatus.
  • the processor may also be configured to instruct the electric motor to change from a cable unwinding operation to a cable rewinding operation, or vice versa, in response to received data from the first electronic detector.
  • the first electronic detector detects and transmits the positions associated with the work member and/or with the grasping means at least 5 times per second, such as at least 10 times per second, such as at least 15 times per second, such as at least 20 times per second, such as at least 25 times per second, such as at least 30 times per second, such as at least 35 times per second, such as at least 50 times per second, such as at least 75 times per second, such as at least 100 times per second, such as at least 150 times per second, such as at least 200 times per second, such as at least 250 times per second, such as at least 300 times per second.
  • the need for a very fast detection and transmission may vary between different operations of the apparatus. If the subject is intended to move the cable at high speed, the first electronic detector must be able to inform the processor accordingly about the positions.
  • the processor is configured to receive and process data at a speed of at least 5 Hz, such as at least 10 Hz, such as at least 15 Hz, such as at least 20 Hz, such as at least 25 Hz, such as at least 30 Hz, such as at least 35 Hz, such as at least 50 Hz, such as at least 75 Hz, such as at least 100 Hz, such as at least 150 Hz, such as at least 200 Hz, such as at least 250 Hz, such as at least 300 Hz.
  • 5 Hz such as at least 10 Hz, such as at least 15 Hz, such as at least 20 Hz, such as at least 25 Hz, such as at least 30 Hz, such as at least 35 Hz, such as at least 50 Hz, such as at least 75 Hz, such as at least 100 Hz, such as at least 150 Hz, such as at least 200 Hz, such as at least 250 Hz, such as at least 300 Hz.
