Abstract
Objective: To investigate the immediate effect of a lumbar spine high velocity thrust, (HVT), technique at level L2,3 on active hip flexion range of motion, (ROM).
Summary of Background data: Lumbar spine HVT techniques are widely used by osteopathic practitioners in the treatment of back and pelvic pain. Recent studies have also linked the effects of spinal HVT to the extraspinal musculoskeletal system. Effects include the reduction of extraspinal muscle hypertonicity and the increase of peripheral joint ROM. Theories proposed to explain these effects include the sudden stretch reflex and the neurophysiological effects of HVT on central sensitisation.
Setting: Exercise Physiology Laboratory, British College of Osteopathic Medicine.
Design: A controlled, same subject, pre and post-test experimental design. Two groups were used: a SHAM intervention group and a HVT intervention group and each subject acted as a control prior to intervention. The control consisted of subject remaining supine for a period of five minutes between pre and post-test measurements. The SHAM intervention group received a single lumbar roll set up with no HVT and the HVT intervention group received a single, unilateral, HVT to the L2,3 region of the lumbar spine in the lumbar roll position. Subjects were randomly allocated to each group and the dependent variable measured was active hip flexion ROM.
Subjects: The subject group consisted of 40 asymptomatic osteopathic college students, 20 male and 20 female. Control consisted of all 40 subjects. SHAM intervention group consisted of 20 subjects, 10 male and 10 female. The age range was 21 to 33 years, (mean 26.5years, SD 4.3years). HVT intervention group consisted of 20 subjects, 10 male and 10 female. The age range was 21 to 35 years, (mean 26.6years, SD 5.3years).
Method: The Universal Standard Goniometer was used to measure pre and post-test measurements of active hip ROM.
Results: Statistical analysis using a paired two-tailed t-test of control measurements showed no statistically significant change in active hip flexion ROM, (p>0.05), indicating there was no measurement effect. Statistical analysis using a paired two-tailed t-test for SHAM intervention group showed no statistically significant change in active hip flexion ROM, (p>0.05), indicating there was no effect from lumbar roll set-up. Statistical analysis using a paired two-tailed t-test for HVT intervention group showed a statistically significant change in active hip flexion ROM, (p<0.05).
Conclusion: Results in this study revealed that an application of a single unilateral L2,3 HVT produces a statistically significant increase in active hip flexion ROM in asymptomatic subjects. This suggests that treatment to the lumbar spine may have a role in the treatment and rehabilitation of peripheral joints. - presented at
