- W2041404346 abstract "Low back pain (LBP) is a serious health problem in America affecting over 80% of the population (NIH, 2006) and is often characterized by a lack of flexibility of the low back and hamstrings. PURPOSE: To explore whether retro locomotion can be an effective means to increase flexibility of the low back and hamstrings, ultimately decreasing LBP. METHODS: Ten healthy female adults (29.9±10.0 yrs; 165.1±8.2 cm; 68.53±18.4 kg) presenting without LBP within the past four months volunteered to participate. The pre-test consisted of participants first warming up with a 2-5 minute forward walk at a personally comfortable velocity followed by three trials of the YMCA Sit-and-Reach test to measure low back and hamstrings flexibility. A biaxial electrogoniometer (Biometrics, model SG 150) was secured externally to the low back vertically spanning T12-S2. Participants then walked backward on a treadmill at their preferred velocity for 10-15 minutes. Low back motion data from the electrogoniometer (1000 Hz) was obtained for 20 sec during the sixth minute of the walk capturing 10 complete walking strides. Following the pre-test, participants completed four weeks of backward walking on a treadmill or over ground for 10-15 minutes/day, four days/week, at the participant‘s chosen velocity. After completing the intervention, a post-test session which duplicated pre-test procedures was conducted. Four dependent variables were identified including maximum sit-and-reach score (SR), walking velocity (Vel) and average sagittal (sROM) and coronal (cROM) range of motion (cROM) of the low back averaged across 10 walking strides. Pre-post differences were evaluated with correlated t-tests (a = 0.05). RESULTS: Statistically greater post-test SR (p<0.001) and Vel (p<0.001) values were observed with no differences for sROM (p=0.289) or cROM (p=0.320). CONCLUSION: Retro locomotion may be a practical means to improve flexibility of the low back and hamstrings as evidenced by improved SR scores. Low back range of motion may not be similarly influenced; however individual responses in low back motion were evidenced." @default.
