Purpose
To relate functional performance and kinesiophobia to muscle strength, fatigue and quality of life in women who survivors breast cancer.
Methods
Participated the study 62 women separate into control group (CNT) (age: 52,16 ± 7,59) and breast cancer survivors group (BCS) (age: 52,93 ± 8,95). The functional performance was evaluated by the DASH, the kinesiophobia it was evaluated by the Tampa Scale, quality of life was evaluated EORTC BR-23, fatigue was evaluated FACT B + 4, the muscle strength was evaluated isometric test bilateral and test 1RM. The normality of the data was evaluated by the Komogorov-Smirnov test. Pearson's correlation was used to evaluate the relationship between the variables that presented normal distribution and the Sperman correlation to evaluate the relationship between the variables that did not present normal distribution. The significance level was considered when the p ≤ 0.05
Results.
The BCS group showed worse levels of functional performance (p < 0,001), bilateral isometric strenght (p < 0,001), test 1RM (p = 0,011) and higher levels kinesiophobia than the CNT group (p = 0,005). Bilateral isometric strenght showed a negative correlation with kinesiophobia (r = 0,295; p = 0,019) and functional performance (r= -0,351; p = 0,005). Functional performance showed negative correlaton with fatigue (r= -0,435; p = 0,0004) and quality of life ( -0,296; p = 0,019).
Conclusion.
BCS women have low levels of functional performance, isometric test bilateral, test 1RM and higher levels of kinesiophobia. The functional performance showed negative correlation with bilateral isometric strenght, fatigue and quality of life. The kinesiophobia showed negative correlation with bilateral isometric strenght.
