핀 수영선수의 만성적 발목 불안정성에 따른 등속성 하지 근력 및 관절가동범위에 관한 연구

Abstract

This study was conducted to examine the changes of isokinetic strength and ROM(range of motion) of ankle, knee, hip, lumbar joints related to chronic ankle instability. The subjects were 8 male Fin swimming athletes who have a chronic ankle instability in one side. We measured ROM of ankle, knee, hip, lumbar joints and isokinetic muscle strength of the lower extremity. In the results, ROM of ankle inversion and lumbar lateral flexion was significantly higher than those of uninvolved(p.05). In addition, the strength of ankle inversion(p.05)/eversion(p.01), knee extension(p.01) and abductiodduction of hip joint(p.05) was significantly lower than those of uninvolved. In conclusion, it was suggested that chronic ankle instability induces weakness of muscle strength and deformation of ROM of lower extremity. Additionally, application of medical treatment and rehabilitation program for chronic ankle instability should be considered the both distal and proximal joints of lower extremity
