Study summary

Brief Summary

This clinical trial aims to learn if static stretching and myofascial release work to improve hamstring muscle tightness and lower limb functional ability among IT professionals. It will also learn about the superiority of one maneuver over another. The main questions it aims to answer are:

  • Does static stretching and myofascial release work to improve hamstring muscle tightness and lower limb functional ability among IT professionals?
  • Which stretching maneuver is more effective in reducing hamstring muscle tightness and improving the lower limb functional ability among IT professionals? Researchers will compare static stretching to myofascial release to see if both work equally or are superior to each other in reducing hamstring muscle tightness and improving lower limb functional ability among IT professionals.

Participants will:

  • Both groups received an application of hot packs for 20-25mins at the posterior aspect of the thigh.
  • In addition, group 1 performed static stretching of the hamstring muscles for thirty seconds, with a thirty-second gap, repeating the same maneuver three times/day for five days/week for three weeks.
  • Group 2 received a myofascial release. This maneuver involves the proper positioning of the practitioner\'s hands on both sides of the hamstrings, pulling them in opposite directions with firm pressure, and holding the stretch for three to five minutes each stretch, completing five to seven stretches per session with a gap of two minutes between each stretch, and continued five sessions per week for three weeks.
Read the detailed description

Tightness in the hamstring muscles presents a considerable issue for many people, especially those in professions requiring long sitting periods, such as IT workers. This group often experiences a high rate of hamstring tightness because their jobs involve extended sitting and minimal physical movement. As a result, IT professionals may suffer from limited knee extension and reduced functionality, leading to discomfort and lower productivity at work and in daily activities.

The impact of hamstring tightness on knee extension and overall function has been extensively studied across various populations. Limited knee extension, commonly associated with hamstring tightness, can disrupt standard walking patterns and affect joint stability, raising the risk of musculoskeletal injuries, particularly around the knee. Additionally, the reduced functional ability caused by hamstring tightness can negatively influence daily tasks, job performance, and overall quality of life.

What researchers measure

Primary outcomes

  1. Active knee extension range of motion (AKE-ROM)

    Hamstring muscle tightness was assessed by active knee extension ROM using a standard full-circle goniometer. The knee angle should be between 80-90 degrees. If the range is below 80 degrees, then that subject has a tight hamstring.

    Time frame: 3 weeks

Secondary outcomes

  1. Lower extremity functional scale (LEFS)

    Lower limb functional ability was assessed using a lower extremity functional scale. The Lower Extremity Functional Scale (LEFS) is scored on a scale of 0 to 80, with higher scores indicating better lower limb function. The interpretation of the scores can be based on the following categories: 0-20: Severe functional limitation; 21-40: Moderate functional limitation; 41-60: Mild to moderate functional limitation; 61-80: Minimal functional limitation or normal function.

    Time frame: 3 weeks
