Effects of William training on lumbosacral muscles function, lumbar curve and pain

BACKGROUND: There are many types of treatments and recommendations for restoring back deformities depending on doctors' knowledge and opinions. The purpose of the exercises is to reduce pain and to ensure stability of the lower trunk by toning the abdominal muscles, buttocks and hamstrings. Given the duration of flares and relapses rate, it is important to apply an efficient and lasting treatment. OBJECTIVE: To evaluate the effects of 8 weeks of William's training on flexibility of lumbosacral muscles and lumbar angle in females with Hyperlordosis. METHODS: Forty female students with lumbar lordosis more than normal degrees (Hyperlordotic) that were randomly divided into exercise and control groups were selected as the study sample. The lumbar lordosis was measured using a flexible ruler, flexibility of hamstring muscles was measured with the active knee extension test, the hip flexor muscles strength was measured using Thomas test, the lumbar muscles flexibility measures by Schober test, abdominal muscles strength measured by Sit-Up test and back pain was measured using McGill's Visual Analogue Scales (VAS) questionnaire. Data were compared before and post-test using independent and paired t-testes. RESULTS: Results showed that 8 weeks of William's exercise led to significant decreases in lumbar angle and back pain, increases in flexibility of hamstring muscles, hip flexor muscles flexibility, lumbar extensor muscles flexibility and abdominal muscles strength. CONCLUSION: The findings show that William's corrective training can be considered as a useful and valid method for restoring and refining back deformities like as accentuated back-arc and became wreaked muscles' performance in lumbar areas.
