1.   To find out the effect of post isometric relaxation muscle energy technique on active knee extension among young adults with hamstring tightness.

2.   To find out the effect of post facilitation stretch muscle energy technique on active knee extension among young adults with hamstring tightness.

3.   To compare the effect of post isometric relaxation and post facilitation stretch on active knee extension among young adults with hamstring tightness.

Ethical clearance will be obtained from Institutional Ethical Committee & Principal of Dr. Ulhas Patil college of Physiotherapy. A written informed consent form will be obtained from subjects who are willing to participate. Subject will be screened according to inclusion and exclusion criteria. The aim of the study and its objective will be explained to willing participants. Selected participants demographics details outcome measures will be recorded.

INTERVENTION

Group A-  post isometric relaxation for hamstring tightness

Ø  Patient position:- The non-treated leg needs to be either flexed  or straight on the table.

      The treated leg should be flexed at both the hip and knee.

Ø  Therapist position:- walk standing

Ø  Technique:- The treated leg should be flexed at both the hip and knee  and then straightened by the practitioner until the restriction barrier is identified.

Ø  The instruction might be something such as ’try to gently bend your knee, against my resistance, starting slowly and using only a quarter of your strength’.

Ø   It is particularly important with the hamstrings to take care regarding cramp, and so it is suggested that no more than 25% of patients’ strength should ever be used during isometric contractions in this region.

Ø  Following the 7-10 seconds of contraction followed by complete relaxation, the leg should, on an exhalation, be straightened at the knee towards its new barrier with the patient’s assistance.

Ø 3 sets of 3 repetition will be given.
