Lumbopelvic injuries are often refractory to treatment and can limit
return to sport. Research shows that 50 Newtons (N) of force applied transversely
to the pelvis improves lumbopelvic stability and pain. This study applies
transverse and diagonal forces to the pelvis in athletes with lumbopelvic pain,
and investigates effects on pain and function. OBJECTIVE:
To investigate the
effects of transverse and diagonal compressive forces applied to the pelvis of
athletes with lumbopelvic pain STUDY DESIGN: A randomized, repeated measures
design using 20 athletes with lumbopelvic pain. METHODS: No belt and four pelvic
belt configurations (50 N force) were tested. Outcome measures were: resting
pain, pain on active straight leg raise (ASLR), resisted hip adduction force and
pain on 1-metre broad jump. Force on the adduction test was determined via load
cell. RESULTS: Data were analyzed using repeated measures ANOVA. Squeeze test
showed significant effect of condition F (4, 76) = 2.7,
P < 0.05. On ASLR
ipsilateral to the side of pain, pain decreased across conditions (F (4, 76) =
2.5 P = 0.05). CONCLUSION: Results suggest application of diagonal forces towards
the site of pain may have additional benefits in improving pain and function.
Such information may inform the development of an orthosis. Clinical relevance
The results may be used clinically to determine the effectiveness of different
belt placements (with belts or straps) in managing athletic lumbopelvic pain. The
results offer an alternative to the application of transverse belts, and may
inform new approaches in the development of orthotics.
