Postural control and shoulder rotators isokinetic strength in squash players with and without idiopathic scoliosis

Abstract

Summary: Idiopathic scoliosis is a postural deformity of the spine that not only changes the shape of the spine but may also alter postural control and muscle strength. Although this deformity is more common in some sports, it is not known whether the scoliosis athlete’s balance and strength are altered. Balance and strength are essential to perform complex technical movements and prevent injuries. This cross-sectional study compared postural control and isokinetic strength of shoulder rotator muscles in squash players with and without idiopathic scoliosis and the control group. We report a higher mediolateral stability index in the frontal plane in scoliosis athletes and this may be associated with increased variability in postural control in the frontal plane. Additionally, the peak torque of the shoulder rotators was not different between the groups. While the relationship between function and posture is complex, these results provide information for preventive health care interventions in scoliosis athletes.
