Relationship of muscle strength with activities of daily living and quality of life in individuals with chronic obstructive pulmonary disease

Abstract Introduction: Few activities of daily living (ADLs) in chronic obstructive pulmonary disease (COPD) are tolerated because they are associated with ventilatory and metabolic changes. Simply lifting the upper limb muscle requires changes, resulting in thoracic abdominal asynchrony, increased dyspnea, and can interfere with quality of life (QoL). Objective: to relate the muscle strength of the shoulder girdle, trunk and hand grip with the degree of dyspnea in ADLs and secondarily correlate them with QoL in individuals with chronic obstructive pulmonary disease. Materials and Methods: Nine male subjects with chronic obstructive pulmonary disease III and IV (COPDG) and nine healthy, sedentary male individuals - control group (CG) were evaluated. All patients underwent the following evaluations: Pulmonary function, muscle strength of shoulder girdle, trunk and hand grip, and questionnaires. Results: In the intergroup analysis found that the spirometric variables of the COPDG were significantly lower compared to the CG. Intragroup analysis for measures of muscle strength, found significant difference for shoulder girdle, trunk and hand grip between both groups (COPDG) with lower mean (CG). Only the shoulder girdle had a positive correlation with ADL's and QoL. Conclusion: COPDG individuals, in addition to having pulmonary compromise, showed a significant decrease in muscle strength of the shoulder girdle, trunk and hand grip when compared to the CG. Only the shoulder girdle strength was positively correlated with the level of dyspnea in ADL's in QoL. Thus, pulmonary rehabilitation is an important tool for strengthening these muscles, possibly providing a positive impact on the degree of dyspnea during ADLs and reflecting on QoL.
