[Purpose] The purpose of this study was to investigate the effects of a pelvic belt on
the activities of trunk and lower extremity muscles in normal adults. [Subjects and
Methods] The subjects were 20 normal individuals without a history of orthopedic problems.
The pelvic compression belt (The Com-Pressor, OPTP, Minneapolis, MN, USA) was an
adjustable body belt with four elastic compression bands that provide stabilizing pressure
and was designed to adjust the amount of force applied and to alter sites of compression.
The body belt was placed below the anterior superior iliac spine, and stabilizing pressure
was applied to the belt using the elastic compression bands in the bridge position after
confirming the site of compression. [Results] The subjects showed a significant decrease
in muscle activation in the erector spinae, oblique internus abdominis, rectus femoris,
and biceps femoris while wearing the pelvic belt. [Conclusion] The use of a pelvic
compression belt with external pelvic compression might improve pelvic joint stability and
alter neuromotor control of the lumbopelvic and thigh muscles.
| Abstract |1 )PURPOSE: This study assessed the effect of the pelvic compression belt on the electromyographic activity of erector spinae (ES), internal oblique (IO), rectus femoris (RF), and biceps femoris (BF) after bridge exercise with pelvic belt compression in subjects with lumbar instability.METHODS: Forty subjects with lumbar instability volunteered for this study. We asked them to perform the bridge exercise while wearing a pelvic belt compression for 30 minutes five times weekly over a six week period. The pelvic compression belt was adjusted just below the anterior superior iliac spines with stabilizing pressure using elastic compression bands during bridge position. Surface electromyographic data were collected from the erector spinae (ES), internal oblique (IO), rectus femoris (RF) and biceps femoris (BF).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
