Background: One of the main causes of musculo-skeletal disorders is muscular imbalance, particularly in urban population who do not have suitable physical activity. These can lead to spinal, lower limb 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 treatments. This has inspired the researchers to investigate the effect of feedback during stretching 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 subjects completed the questionnaire from voluntaril, then they were randomly divided to three groups of 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 weekends).
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 tests 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 among the groups.
Conclusion: According to relatively equal results of three stretching execises, it seems that the use of feedback simultaneously with stretching can encourage the patients to perform their exercises as much as possible.
Key words: Stretching, Static and dynamic flexibility, Hamstring, Feedback
