Abstract:
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.
