Upper Extremity Activities Of Daily Living Research Articles

BackgroundUpper-extremity exercise is for pulmonary rehabilitation. The 6-minute pegboard and ring test (6PBRT) was developed to evaluate arm exercise capacity in patients with chronic obstructive pulmonary disease (COPD). The purpose of this study was to characterize the 6PBRT and evaluate its relationship with upper-extremity activities of daily living (ADLs) in COPD patients.MethodsTwenty outpatients with mild to very severe COPD underwent the 6PBRT and spirometry, and their maximal inspiratory and expiratory pressures and grip strength were measured. For the 6PBRT, subjects were asked to move as many rings as possible in 6 minutes, and the score was the number of moved rings during the 6-minute period. Upper-extremity ADLs were evaluated with the upper extremity activities subdomain of the modified Pulmonary Functional Status and Dyspnea Questionnaire. Upper-extremity ADLs were also measured objectively by using a wrist accelerometer every day for 1 week.ResultsThere was a positive correlation between 6PBRT score and inspiratory capacity (r = 0.71, P , 0.001), inspiratory capacity/total lung capacity predicted (r = 0.68, P , 0.01), and forced vial capacity (r = 0.57, P , 0.01). There was also a positive correlation between 6PBRT score and accelerometer count (r = 0.54, P , 0.05) and a negative correlation between 6PBRT score and arm activity score (ρ = −0.49, P , 0.05).ConclusionThe 6PBRT may be a predictive test to maintain and improve upper-extremity ADL during pulmonary rehabilitation in patients with COPD.
