Abstract: 

Background: One of the main causes of musculo-skeletal disorders is muscular imbalance, particularly in urban population who do not have suitable physical activity. This can lead to spinal, lower limbs and gait abnormalities. Applying the most appropriate and effective technique to stretch the shortened muscles is very important in these patients.
The current belief is that using biofeedback simultaneously with exercise therapy may increase the effect of the treatment. This has prompted the researchers to investigate the effect of feedback during stretching the hamstring muscle.
Materials and Methods: A randomized single blinded clinical trial was conducted on 45 female volunteers from Fateme Zahra Dormitory of Shahid Beheshti University (20-25 years old). All of the participants were asked to complete a questionnaire. Then they were randomly divided into three groups each one consisting 15 subjects. We considered three stretching techniques (static stretch, dynamic stretch with audio-sensory feedback and dynamic stretch only). The treatment course took 4 weeks (every day except Thursday and Friday).
The flexibility of the hamstring muscle was assessed by measuring the Range of Motion (ROM) directly by a goniometer and also indirectly by Sit & Reach test at the start and the end of the treatment courses. A t-test and Tukey-B test were used to analyze the data.
Results: According to the statistical analysis, all of the three stretching techniques significantly improved the flexibility of the hamstring muscles, however there was no significant differences between the techniques.
Conclusion: Considering the relatively identical results of three stretching excises, it seems that the use of feedback simultaneously with stretching can encourage the patients to perform their exercises as much as possible
