Brief Summary

Tightness of hamstring muscle is known as a reduction in range of motion accompanied by a sensation of restriction in the posterior aspect of thigh. Numerous reasons can cause it, such as genetic susceptibility, compensatory tightness due to persistent abnormalities, and muscular strain. Tight hamstrings cause a small amount of knee flexion during exercise and require comparatively high quadriceps efforts to offset the hamstrings' passive resistance. This could result in knee joint pain that affects gait and raise the reaction forces at the patellofemoral joint.

Conditions

Hamstring Muscle Tightness

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

Group A (Virtual reality group)

Participants will receive virtual reality (VR) in addition to the traditional physical therapy program 2 times/week for 5 weeks.

Group Type: EXPERIMENTAL

Virtual reality

Intervention Type: DEVICE

A five-minute warm-up, thirty minutes of intervention training, and a five-minute cool-down will all be included in each session. Five minutes of stretching and walking were part of the warm-up. Every participant will play five sports games (running, cool-running, catching gift, football, skate) during each session. These gamed can help teenagers to improve their physical strength, endurance, balance, and coordination. Every game lasted Five minutes.

Traditional physical therapy programme

Intervention Type: OTHER

The exercise programme includes farmer walks, squats, calf raises, stretching exercises, and strengthening activities. The exercises will be performed in one or two sets of 15-20 repetitions, with a 60-second rest in between. The sets, repetitions, and loads will be increased as the participants advance, up to three sets of 60 repetitions for a perceived effort of 70%-80% of 1RM

Group B (control group)

Participants will receive a traditional physical therapy program only, 2 times per week for 5 weeks.

Group Type: ACTIVE_COMPARATOR

Traditional physical therapy programme

Intervention Type: OTHER

The exercise programme includes farmer walks, squats, calf raises, stretching exercises, and strengthening activities. The exercises will be performed in one or two sets of 15-20 repetitions, with a 60-second rest in between. The sets, repetitions, and loads will be increased as the participants advance, up to three sets of 60 repetitions for a perceived effort of 70%-80% of 1RM
