[AIM] The purpose of this study is to investigate the differences in the M-test scores, self-awareness scores, and the general physical condition of boxers with or without a history of low-back pain (LBP).
[Design] Cross-sectional, case-control study.
[Setting] The subjects of our study were 20 university boxers. The subjects were divided into 2 groups on the basis of LBP history: group 1 included subjects with a history of LBP, and group 2 included subjects without a history of LBP. The study was performed during a summer training camp from September 9, 2005 to September 15, 2005.
[Main outcome measure] We obtained the M-test scores for trunk and leg movements in both groups of subjects. The self-awareness assessment comprised 9 items, including 4 items related to sports training and 5 items related to the subjects\' perception of their physical condition.
[Results] The M-test scores of subjects with a history of LBP were higher than those of subjects with no history of LBP, thereby reflecting the lower flexibilities of the hip joint and trunk regions of the subjects with LBP. The baseline physical-condition scores of the 2 groups were significantly different. We also observed significant intergroup differences in day-6 scores for self-assessment of physical condition upon rising in the morning.
[Conclusion] Application of M-test in combination with subjective evaluation of the subjects may prove useful for athletes and help prevent external injuries.
