Brief Summary

This study compared the effects of dynamic oscillatory stretch technique (DOS) and static stretching (SS) technique in order to improve hamstring extensibility in healthy individuals with asymptomatic hamstring tightness. Half of study participants received DOS whereas other half received static stretching technique.

Conditions

Keywords

Flexibility; Extensibility; Static stretching

Outcome Measures

Primary Outcomes (8)

• Active Straight Leg Raise Test(ASLR) Immediate effect

  Changes from baseline Active Straight Leg Raise Test(ASLR) was conducted with the participants in supine lying with both lower limbs initially extended. Then patient actively lifted the leg to be tested at hip joint while stabilizing the leg opposite to that of the testing side by using a stabilization belt. Knee on testing side was essentially sustained in full extension throughout the full testing range. Universal goniometer was used to measure range of motion available at hip joint. Cut off score for the SLR to indicate hamstring tightness is 80 degrees. Therefore, values of SLR below 80 degrees was considered as hamstring tightness. Assessment was done Immediate after giving intervention(10 minutes).

• Active Straight Leg Raise Test(ASLR) 1 hour effects

  Changes from Baseline Active Straight Leg Raise Test(ASLR) was conducted with the participants in supine lying with both lower limbs initially extended. Then patient actively lifted the leg to be tested at hip joint while stabilizing the leg opposite to that of the testing side by using a stabilization belt. Knee on testing side was essentially sustained in full extension throughout the full testing range. Universal goniometer was used to measure range of motion available at hip joint. Cut off score for the SLR to indicate hamstring tightness is 80 degrees. Therefore, values of SLR below 80 degrees was considered as hamstring tightness. Assessment was done after 1 hour of intervention.

• Active Knee Extension Test (AKE) immediate effect

  Changes from Baseline Active knee extension test (AKE), is used to assess hamstring length. It was performed while the participant was in supine lying and involved leg was in 90 degree hip flexion. then participant was asked to extend the knee. For hamstring tightness cut off score AKE angle is 160°. Therefore normal individuals with angle \< 160° were considered as individuals with hamstring tightness.Its reliability is 0.94.Assessment was done Immediate after giving intervention(10 minutes).

• Sit and Reach Test (SRT) Immediate effects

  Changes from Baseline Sit and reach test (SRT) is most commonly employed test to measure hamstring flexibility. This tool is used to measure range of hamstring muscle at knee joint.Each participant was instructed to sits on a couch in long sitting position. participants were seated with elongated legs, with hip flexed to 90 degrees and knees were fully extended and the ankles were in relaxed plantar flexion. A measuring ruler/tape was placed,between the feet with 38 cm score was marked tangent to the sole of the feet. Subjects were asked to reach forward with hands one above the other and palms of the hands facing down, while attempting to touch fingertips to toes or as far beyond on measuring tape while keeping the knees straight. Assessment was done Immediate after giving intervention(10 minutes).

• Passive Straight Leg Raise Test(PSLR) Immediate effects

  Changes from Baseline PSLR test was conducted with the participants in supine lying with both lower limbs initially extended. Then therapist lifted the leg to be tested at hip joint while stabilizing the leg opposite to that of the testing side by using a stabilization belt. Knee on testing side was essentially sustained in full extension throughout the full testing range. Universal goniometer was used to measure range of motion available at hip joint.
