Abstract: BACKGROUND: Hamstring tightness induces posterior pelvic tilt and
decreased lumbar lordosis, which can result in low back pain OBJECTIVE: We investigated effects of hamstring stretch with pelvic
control on pain and work ability in standing workers. METHODS: One hundred adult volunteers from a standing workers were
randomly assigned to pelvic control hamstring stretching (PCHS) (n = 34),
general hamstring stretching (GHS) (n = 34), control (n = 32) groups. The
control group was performed self-home exercise. All interventions were
conducted 3 days per week for 6 weeks, and included in the hamstring
stretching and lumbopelvic muscle strengthening. Outcomes were evaluated
through the visual analog scale (VAS), straight leg raise test (SLR), sit
and reach test (SRT), Oswestry disability index (ODI), and work ability
index (WAI). RESULTS: Significant difference in VAS, SLR, SRT, ODI, and WAI were
found in the PCHS and GHS groups. The control group was a significant
difference only in ODI. The PCHS group showed a greater difference than the
GHS group and control group in VAS, SLR, SRT, and ODI. CONCLUSIONS: The pelvic control hamstring stretch exercise would be
more helpful in back pain reduction and improvement of work ability in an
industrial setting.
