Description
Technical field
The utility model relates to the rehabilitation equipment field, particularly a kind of exercise for power and assessment device.
Background technology
Muscle function inspection and evaluation are the most basic in the medical science of recovery therapy, one of important contents.Inspection to muscle function helps to understand the patient's muscle and the neural extent of damage, and making regular check on before and after the training can be used as the index of evaluation rehabilitation effect.
In clinical, when patient's muscular strength during, should carry out resistive exercise at 34 grades, make muscle bear bigger resistance at the volley and raise rate, thereby promote that muscular strength increases quickly to increase muscle fibre.In orthopedic injury and disease, as do not have serious nervous lesion, muscular strength is many more than 3 grades, and therefore, the impedance training is used very extensive.
According to the difference of contraction of muscle mode, can be divided into the impedance training of using in the medical science of recovery therapy following several:
1, istonics claims dynamic training again, the impedance training that promptly utilizes the muscle isotonic contraction to carry out.So-called isotonic contraction is meant that muscle tone is greater than resistance when shrinking, and muscle can freely shorten the joint motions that cause response, therefore is called dynamic property again and shrinks.The typical method of istonics is directly or by pulley to lift the training of weight, as lift the dumbbell, sandbag or chest expander training.The exercise load that is characterized in used apparatus generation is constant.The maximum moment difference that muscle produces, the load that can overcome is also different, in order to finish the motion of whole range, load can not be too big, add that motion is subjected to the influence of inertia when quickening with deceleration, the moment of resistance can not be often and the maximum moment of muscle match, make that most time moment of resistance is lower than the muscle maximum moment in the motion, the effect that influence is taken exercise.The key of promoting muscular strength with istonics is just can cause muscular fatigue in the hope of the motion that repeats less number of times, the principle that promptly big load repeats less with big resistance.
2, isometric training, the exercise for power that promptly utilizes the muscle isometric contraction to carry out owing to do not cause tangible joint motions, therefore, is called isometric training again.So-called isometric contraction is meant that muscle does not significantly shorten or prolongs, and does not produce tangible joint motions simultaneously when the tension force of contraction of muscle matches with resistance, so isometric contraction is called the static(al) contraction again.Isometric training is easy and simple to handle, can be fixed at limbs, range of motion is obviously restricted or exist joint injury to comprise under the situations such as chondomalacia or arthritis carries out, and with timely prevention muscular atrophy or promote Myodynamia recovery, is widely used in the orthopaedics rehabilitation.Its shortcoming is to be considered to mainly strengthen static muscular strength.And significant angle specificity is arranged, promptly only effective to the muscular strength near the about 20 degree scopes enhancing training angle.
3, constant speed training promptly utilizes the constant speed of muscle to shrink the impedance training of carrying out.So-called movement at the uniform velocity, be meant at the volley, movement velocity is constant and resistance is variable, speed in the motion is set on the constant speed instrument in advance, in case setting speed, no matter the experimenter uses great strength, the speed of limb motion can not surpass predefined speed, experimenter's subjectivity firmly can only make muscle tone promote, and moment output increases, and a kind of motion that can not produce acceleration.During movement at the uniform velocity, muscle fibre length can shorten or elongate, and causes tangible joint motions, is that a kind of dynamic property is shunk.Be similar to the muscle isotonic contraction.But in the motion, the constant speed instrument provides a kind of compliance resistance, the size of resistance size marrow contraction of muscle tension force and change similar muscle isometric contraction.Therefore, the constant speed contraction of muscle has some characteristic or the advantage of isotonic contraction and isometric contraction concurrently, is a kind of special contraction of muscle form.
In addition, when patient's muscular strength is not enough to carry out the impedance training, need medical personnel or rehabilitation equipment, carry out passive exercise patient's application of force.
At present, domestic constant speed to the upper and lower limb muscular strength of patient, isometric and passive exercise is most of is finished by simple equipment such as simple rehabilitation material such as dumbbell, sandbag by medical personnel, and the data of the science of neither one as a result of training are compared and diagnose.And carry out constant speed test or training, need special constant speed instrument.At home, the muscle force recovering Study on Technology is at the early-stage, does not up to the present also carry out the exploitation and the development of rehabilitation instrument.The equipment of all uses all relies on import, therefore, study and all carry out round the import equipment of costliness, need a large amount of fund of cost, this has limited the development of China in this field greatly.Because apparatus expensive, in rehabilitation and clinical medicine work the research of muscle force recovering also seldom, thereby limited the development of muscle force recovering equipment conversely again.
