The 6-minute pegboard and ring test is correlated with upper extremity activity of daily living in chronic obstructive pulmonary disease

Abstract

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.

Arm Activity During Daily Life in Individuals With Chronic Obstructive Pulmonary Disease

“…However, we found no significant correlations between these variables. Our observations conflict with the findings of Takeda et al, 29 who found positive significant correlations between an unsupported arm functional test (6-minute pegboard and ring test) and measures of daily wrist activity (measured using an accelerometer) in individuals with COPD. However, the authors did not attempt to isolate arm activity from overall physical activity, and therefore the positive correlations of the 6-minute pegboard and ring test with the wrist accelerometer in their study may reflect a relationship between the overall level of physical activity with the individual's functional status.…”

“…33,34 The shuttle test, despite less use than the 6MWT, also has the ability to measure physical capacity changes in COPD submitted to an intervention. 35 In addition, unsupported upper-limb tests could also describe the functionality of COPD patients 36 and could be taken alone or in conjunction with the 6MWT or shuttle test.…”
