Modified Sciatic Nerve Mobility Exercises on Hamstring Tightness

Each participant was made to lie down in a supine position on the treatment couch. The participant's leg was moved to about 30-45 degrees hip flexion with knee extension. The ankle was then moved to maximum dorsiflexion with inversion and hip internal rotation within the participant's tolerance, and this position was maintained for 30 seconds. While the therapist performed dorsiflexion with inversion and hip internal rotation in the supported straight leg raise position, the participant was instructed to actively flex the cervical spine slowly until they perceived a tolerable stretch sensation in the hamstring muscle and lower leg. The synchronous alternating movements were performed rhythmically for 10-15 repetitions. This maneuver was repeated 3 times in a single session, 3 days per week, and continued for 3 consecutive weeks.

"The participant was instructed to stand straight with the unaffected foot supported on the floor and the toes pointing forward. The heel of the testing leg was placed on an 18 high step with the toes directed upwards with knee extension. Once cued, the participant was asked to flex forward at the hip while maintaining the spine in a neutral position and reaching the arms forward. The knee joint remained fully extended as the participant continued to flex the hip until a gentle stretch was felt in the posterior thigh. Once the position was achieved, the participants were asked to hold it for 20-30 seconds. The same procedure was repeated 3 times daily, 3 days a week for three consecutive weeks."
