The reason for this disorder is damage to the roots and nerves innervating the muscles of the trunk and lower extremities, which leads to their weakening or paralysis. Most often, the Landing symptom occurs with radiculitis at the level of L4-L5 or L5-S1 vertebrae.
Thus, the Landing symptom is an important diagnostic sign indicating damage to the lower lumbar and upper sacral spinal nerves. Timely recognition of this symptom helps to correctly diagnose the disease and prescribe the necessary treatment.
**Squatting symptom** is a symptom of damage to peripheral nerves, characterized by the inability for a patient in a supine position with damage to the lumbar plexus (compression of the L4-L5 roots) or sacral plexus with incomplete shortening of one of the lower extremities to abduct the leg towards the gluteus maximus muscle with simultaneous by lifting the pelvis with bringing the knees and shins inward and
