The glide exercise may also be performed by sitting up in a straight chair with your knees bent at 90Â° and then slowly straightening the leg.

Reflexes help to maintain proper muscle tone, balance, and responsiveness of the legs and feet to stimuli such as stepping on a sharp object. The nerves of the leg and foot arise from spinal nerves connected to the spinal cord in the lower back and pelvis. As these nerves descend toward the thighs, they form two networks of crossed nerves known as the lumbar plexus and sacral plexus. The lumbar plexus forms in the lower back from the merger of spinal nerves L1 through L4 while the sacral plexus forms in the pelvic region from spinal nerves L4, L5, and S1 through S4.
