Does physiotherapy plus cognitive training improve balance in Parkinson's disease? Randomized clinical trial
Motriz: Revista de Educacao Fisica
Aims: Postural instability is intrinsically related to cognitive dysfunctions in Parkinson's disease (PD), which supports the importance of multimodal treatments. The purpose of this study was to investigate the effectiveness of adding cognitive training to motor physiotherapy in comparison with motor physiotherapy in the balance of individuals with PD. Methods: randomized clinical trial, where the individuals were randomized to two treatments: Physiotherapy Group (PG; n=29; M=12; HY= 2.5
... M=12; HY= 2.5 [2-3]) executed balance training; Physiotherapy plus Cognitive Training Group (PCG; n=29; 10M; HY= 2.5 [1.5-3]), balance training plus a cognitive training at the end of the therapy. Evaluation instruments: Balance Evaluation Systems Test (BESTest); Unified Parkinson Disease Rating Scale (UPDRS). Results: The intragroup analysis revealed that both groups presented improved balance and UPDRS total score after execution of the protocols, but without statistically significant intergroup differences. The effect sizes were small for all the comparisons. Conclusion: There was no difference between the proposed treatments (PCG and PG). However, both interventions benefitted the individuals' balance and signs and symptoms of PD, when considered the time effect.
