Abstract
Background: Primary ciliary dyskinesia (PCD) affects exercise capacity and peripheral muscle strength. Chronic respiratory diseases may cause balance impairment associated with peripheral muscle weakness.
Aim: To investigate the relationship between exercise capacity, peripheral muscle strength, and balance in PCD.
Method: Thirty-seven PCD children (14.10±2.44 years, 22F, 15M, %FEV1: 75.98±11.48) were included. Exercise capacity was assessed using an incremental shuttle walk test (ISWT). Quadriceps muscle strength (QMS) was evaluated using a hand-held dynamometer. Dynamic balance was evaluated using the Y balance test (Y-BT). Norm values were used to evaluate the presence of impairment.
Results: The ISWT distance was 635.1±146.6 m, QMS was 21.3±9.8 kg, and the composite reach distance of Y-BT was 79.8±16.1 cm, respectively. The ISWT distance was positively correlated with QMS (r=0.525), and the composite reach distance of Y-BT (r=0.428) values (p<0.05). The QMS was positively associated with the composite reach distance of Y-BT (r=0.557, p<0.001).
Conclusions: ISWT, QMS, and Y-BT parameters were impaired in children with PCD. Exercise capacity, peripheral muscle strength, and dynamic balance were moderately related in PCD. Considering the associations between these parameters, further study is needed to investigate whether balance assessment and training should be added to pulmonary rehabilitation to prevent deterioration in exercise capacity and peripheral muscle strength in children with PCD.
