Comparison of Post Isometric Relaxation and Post Facilitation Stretching on Hamstring Muscle Flexibility
Condition: Hamstring Injury
Study type: Interventional

Summary: 
      The goal of this randomized clinical trial is to check the effectiveness of post isometric
      relaxation and post facilitation stretching on hamstring muscle flexibility in collegiate
      athletes.

      The main question it aims to answer is:

        -  To compare the post isometric relaxation and post facilitation stretching techniques on
           hamstring muscle flexibility in collegiate athletes Participants were divided in two
           groups,

        -  Group-A was treated with baseline treatment of heating for 15min and rehab protocol post
           isometric relaxation in which 3-5 repetitions for 7-10 seconds hold in each session for
           three sessions per week in alternate days for four weeks.

        -  Group-B was treated with baseline treatment of heating for 15min and rehab protocol post
           facilitation in which 3-5 repetitions for 7-10 seconds hold in each session for three
           sessions per week in alternate days for four weeks.
    

Detailed description: 
      Hamstring injuries are most common injuries in sports and there are many treatment methods
      and rehabilitation protocols available which are used according to the extent of injury. The
      main purpose of this study was to check the effectiveness of two treatment techniques on the
      hamstring muscle flexibility in collegiate athletes. Muscle Energy Techniques (MET) and their
      related post-isometric relaxation and post facilitation stretching techniques have
      demonstrated better results in improving flexibility of the tightened muscles. The study was
      a randomized clinical trial at Pakistan sports board and coaching center Lahore in which
      convenience sampling technique was used. This study included total 48 participants and for
      this purpose Open Epi tool software was used as a sample size calculation. Participants
      falling in this category were recruited into the study, those were male athletes with ages 18
      to 35 having bilateral hamstring muscle tightness and acute hamstring injuries. Participants
      failing to fall in this category were excluded of the study such as females and athletes with
      hip, buttock and low back pain radiating to back of thigh and history of fractures within 6
      months. Universal goniometer, SLR, active knee extension test and sit to reach test would be
      used as a tool for pre and post assessment of athletes. In this study the subjects were
      assigned through convenience sampling into two groups. Group A was treated with post
      isometric relaxation technique and group B was treated with post facilitation technique. Data
      will analyze through SPSS version 25.0
