Parameters of isometric muscle strength testing do not include isometric time.
Introduction of muscle strength:
Muscle strength refers to the force of muscle contraction when a limb makes a random movement. The method of examination is to ask the patient upper and lower limbs in turn for each joint extension, flexion movement, and against the resistance given by the examiner, to observe whether the muscle strength is normal, reduced or paralyzed, and pay attention to the site of paralysis.
Generally, the upper limbs are used for abduction and adduction of the upper arm, extension and flexion of the forearm, extension and flexion of the wrist, abduction and adduction of the fingers, and clenching of the fist. Lower limbs for hip flexion, calf extension and flexion, foot plantar and dorsiflexion. Each of the muscles involved should be examined separately when the condition warrants it.
Clinical significance:
Varying degrees of muscle weakness can be classified as complete paralysis and incomplete paralysis (hemiplegia).
Different parts or different combinations of paralysis can be named separately: monoparesis: paralysis of a single limb, most often seen in poliomyelitis; hemiparesis: paralysis of one side of the limbs (upper and lower limbs) is often accompanied by damage to the cranial nerves of the side, most often seen in intracranial damage or stroke.
Cross hemiplegia: paralysis of one side of the limbs and damage to the contralateral cranial nerves, most often seen in brainstem lesions; paraplegia: paralysis of both lower limbs, as a result of transverse injury to the spinal cord, most often due to spinal cord trauma, inflammation.
Extended information:
The concept of isometric plyometrics was first pioneered in 1969 by sports medicine experts such as Hislop, Perrin, and Sestel. After more than half a century of research and development, isometric muscle testing and training techniques have now become one of the main modalities of sports rehabilitation, very mature and effective.
The theory behind isokinetic testing and training is based on the use of a special rehabilitation device where the speed of the device remains constant and the resistance varies according to the force exerted by the user. The speed of movement remains constant no matter how much or how little force is applied. During muscle strength training, the muscles contract at every angle of the joint to maximize the strength effect.
Speed plyometrics increases muscle strength, improves explosive power and enhances muscular endurance. It is recognized as the safest and most effective strength training in rehabilitation and sports science today. However, before undergoing isokinetic plyometric training, it is essential to perform a full joint isokinetic plyometric test.
This type of isokinetic testing covers the six major joints of the human body: shoulder, elbow, wrist, hip, knee and ankle, and allows for isometric, isotonic, isometric, centrifugal, centripetal, and sustained passive and other related programs to be evaluated. When the limbs are in isometric motion, the functional status of the muscles is evaluated by determining a series of parameters that reflect the muscle load.
