Extra-articular snapping hip syndrome is commonly associated with leg length difference (usually the long side is symptomatic), tightness in the iliotibial band (ITB) on the involved side, weakness in hip abductors and external rotators, poor lumbopelvic stability and abnormal foot mechanics (overpronation).

Myoclonus is a brief, involuntary, irregular (lacking rhythm) twitching of a muscle, a joint, or a group of muscles, different from clonus, which is rhythmic or regular.. Myoclonus (myo-"muscle", clonus "spasm") describes a medical sign and, generally, is not a diagnosis of a dis

This is not a bodyweight exercise, the only body part actually being lifted is the small weight of the foot. The resistance comes from the sledge.
Involuntary extension of the "normal" leg occurs when flexing the contralateral leg against resistance. To perform the test, the examiner should hold one hand under the heel of the "normal" limb and ask the patient to flex the contralateral hip against resistance (while the patient is supine), asking the patient to keep the weak leg straight while raising it.
A peroneal strike is a temporarily disabling blow to the common fibular (peroneal) nerve of the leg, just above the knee. The attacker aims roughly a hand span above the exterior side of the knee, towards the back of the leg. This causes a temporary loss of motor control of the leg, accompanied by numbness and a painful tingling sensation from ...
To test the medial meniscus, the hand at the heel applies a valgus force and external rotates the leg while extending the knee. To test for the lateral meniscus, the varus force, internal rotation are applied to the leg while extending the knee. Any clicking, popping, or catching at the respective joint line indicates the corresponding meniscal ...
