Efficacy of Hamstring Stretching According to the Neural or Muscle Tissue Involvement

The stretched lower limb was on a mobile support and the contralateral limb was stabilized with a belt on the bench. For the SLR, the knee was kept in full extension and then, hip flexion was performed until a marked resistance. All stretching modalities were applied until a marked resistance was felt by the physical therapist (end-feel) or until the point of maximal tolerance referred by subjects.The stretch lasted 30 seconds followed by 15 seconds rest period and the procedure was repeated 5 times. Each stretching was applied for 5 minutes
