NCT04024839

Brief Summary

This study was intended to compare the immediate, short term and long term effects of active isolated stretch versus post isometric relaxation on hamstring flexibility in young healthy adults.35 students were assigned randomly into two groups with 17 and 18 in each group. Group A was given post isometric relaxation while Group B was Active isolated stretch. 22.2 year male and female students with tight hamstring were included while any neurological and orthopedic disorder were excluded. Active Isolated Stretch and Post Isometric Relaxation at baseline, after first and final exercise session were calculated immediate and short term effects while long term effects were calculated after two weeks of final session.

Outcome Measures

Primary Outcomes (1)

  • Active knee extension score

    The Active Knee Extension Test is used to assess hamstring muscle length and the range of active knee extension in the position of hip flexion. The measurement unit is degrees on the goniometer.

    Upto 5 weeks

Secondary Outcomes (1)

  • Sit and reach test

    Upto 5 weeks

Other Outcomes (1)

  • Lower extremity functional scale

    after 2 weeks of intervention

Study Arms (2)

Post Isometric Relaxation

ACTIVE COMPARATOR

Post Isometric Relaxation was applied three times a week for the duration of three weeks.

Other: Post Isometric Relaxation

Active Isolated stretch

EXPERIMENTAL

Active Isolated stretch was was applied three times a week for the duration of three weeks.

Other: Active Isolated Stretch

Interventions

In supine position, participant was asked to lock the knee and slowly lift leg using the quadriceps muscles. gentle assistance was given by the rope at the end of the movement, as the quadriceps muscles continue to move the leg. strech was applied for 2 sec and then release to starting position. two sets of 10 repetitions were performed.

Active Isolated stretch

In supine line, participant was asked to do SLR until resistance was met in hamstring muscles and then was asked to do isometric contraction (10-20% of maximum) for 5 - 10 sec and inhale. After this, patient was asked to exhale while doing so gentle stretch was applied till the new barrier. Starting from this new barrier, the procedure was repeated 2 - 3 times.

Post Isometric Relaxation
