Use of PNF and Tissue Flossing to Treat Hamstring Tightness in Young Female Students

The goal of this clinical trial is to learn tissue flossing and proprioceptive neuromuscular facilitation effect in treating hamstring muscle tightness.

The main questions it aims to answer are:

1. which technique is more useful in giving instant relaxation of hamstring muscle 2. can these technique increase muscle flexibility and knee motion

Researchers will compare Tissue flossing to a PNF (Proprioceptive neuromuscular facilitation) to see which on is more effective.

Participant will:

1. be provided one technique either tissue flossing or PNF in first day 2. physiotherapist will immediately measure the the change in flexibility or knee motion

2. another technique will be applied after 1 week 3. again change in flexibility and knee motion will be recorded

Treatment and study plan

tissue floss band

Other

Floss band is wrapped in thigh from distal to proximal for 2 minutes. during this period patient is asked to actively perform movement for 2 minute, after that the band is removed and repeated once more. Immediately followed by flexibility measurements

Other names: Floss band

Proprioceptive Neuromuscular facilitation

Other

Proprioceptive Neuromuscular Facilitation (PNF) Stretching using the hold-relax method: participants perform an isometric contraction of the hamstring at the end of its stretch range , followed by relaxation and passive stretch, then flexibility assessed similarly

Primary outcomes

  1. Active Knee Extension Test

    Time frame: From enrollment to the end of treatment at 1 week

    With the participant supine and the hip flexed to 90°, the participant actively extends the knee. A goniometer was used to records the knee extension angle. Three trials are performed and the mean is used for analysis.

  2. Passive Knee Extension Test

    Time frame: From enrollment to the end of treatment at 1 week

    With the participant supine and the hip flexed to 90°, the examiner passively extends the knee until the first onset of resistance. A goniometer is used to records the knee extension angle. Three trials are performed and the mean is used.

  3. Straight Leg Raise

    Time frame: From enrollment to the end of treatment at 1 week

    With the participant supine, the examiner passively raises the extended leg until resistance . A goniometer at the hip measures maximum hip flexion angle (degrees). Three trials are performed and the mean is used.

  4. Sit-and-Reach Test

    Time frame: From enrollment to the end of treatment at 1 week

    The participant sits with legs extended and reaches forward along a standard sit-and-reach box . After a warm-up, three trials are performed and the mean score (cm) is recorded.
