Single pretest-post clinical trial to find immediate effects of functional dry needling to increase the length of the shortened hamstring. This study will be carried on single group which will include male subjects only. The data will be recorded before and immediately after the treatment. A monofilament stainless steel needle will be inserted on three points on hamstring muscle which will include semitendinosus, semimembranosus and bicep femoris. Treatment session will consist of 1 minute 20 seconds for each point on the hamstring and the manipulation will be performed by Pistoning technique in which the needle will be drawn out (not fully out of skin) after inserted and then again pushed in and data will be recorded after the treatment session on the basis of increase in length of hamstring which will be measure through 90-90 SLR (AKE) and on the lower extremity functional scale (LEFS)
The aim of this study is to find whether functional dry needle is helpful to increase the length of shortened hamstring muscle or not
