Introduction: The upper crossed syndrome is a type of musculoskeletal disorder in the upper extremity, leading to deformities such as forward head, round shoulder, and hyper kyphosis. The aim of this study was to investigate the effect of eight weeks of corrective exercises carried out in water on static and semi dynamic balance in patients with upper crossed syndrome (UCS).
Methods: In this randomized controlled clinical trial, after initial screening, 30 students with UCS were selected and were assigned randomly into experimental (n=14) and control (n=16) groups. Before and after the intervention, static and semi dynamic balance variables were measured by Biodex Balance System (BBS). Data was analyzed by SPSS software version 20 (Inc, Chicago, IL). The significance level was 0.05. Paired sample t-test was used to compare the mean of the pretest to posttest and independent t-test was used to compare the differences between groups.
Results: The results showed that the experimental group had significant improvement in static (P= 0.005) and semi dynamic balance (P= 0.002) (overall stability), also in static (P= 0.001) and semi dynamic balance (P= 0.003) (the anterior – posterior stability). But in the static (P = 0.720) and semi dynamic (P = 0.426), balance (lateral stability), the effect was not significant.
Conclusion: In this study, the focus of the corrective exercises protocol was on postural correction and its effects on balance improvement. The overall stability and the stability of the anterior - posterior direction improved after abnormalities correction. So, this protocol can be recommended as an effective protocol to improve posture and balance in the patients with upper crossed syndrome.
