Brief Summary

This study included collegiate students with tight hamstring muscles aged between 18-23 recruited from the Gulf Medical University, Ajman, UAE to compare the effectiveness of modified sciatic nerve mobility exercises and dynamic hamstring muscle stretching (DHMS) on hamstring length in collegiate students with hamstring muscle tightness.

Conditions

Hamstring Tightness

Keywords

Hamstring tightness; Neurodynamic; neural mobilization; Muscle stretching

Outcome Measures

Primary Outcomes (1)

• Passive Knee Extension (PKE) ROM test

  To measure the hamstring length using Passive Knee Extension (PKE) ROM test, the participant was in supine position on the plinth, the hip and knee of the lower limb to be tested kept at 90° flexion.

  Baseline, post-treatment day 1, end of week 1, and week 2

Study Arms (2)

Group 1: MSNM

EXPERIMENTAL

The participants in this group are treated with modified sciatic nerve mobilization.

Procedure: Modified sciatic nerve mobility exercises

Group 2: DHMS

ACTIVE COMPARATOR

The participants in this group are treated with dynamic hamstring muscle stretching.

Procedure: Dynamic hamstring muscle stretching

Interventions

Modified sciatic nerve mobility exercises PROCEDURE

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.

Group 1: MSNM

Dynamic hamstring muscle stretching PROCEDURE

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.

Group 2: DHMS
