Efficacy of a Structured Exercise Program for Improving Functional Capacity and Quality of Life in Patients With...

This study investigated the effects of an exercise program on functional capacity and quality of life in patients with stage 3 and stage 4 sarcoidosis.

Eighteen patients with stage 3 and 4 sarcoidosis were recruited; 9 received 12 wk of supervised exercise training and 9 received usual care. Patients underwent the following evaluations at baseline and follow-up: 6-min walk test, maximal inspiratory and expiratory pressure tests, back and leg dynamometer test, modified Medical Research Council Dyspnea Scale, Fatigue Severity Scale, St George Respiratory Questionnaire, Short Form-36 Quality of Life Questionnaire, Hospital Anxiety and Depression Questionnaire, body plethysmography, carbon monoxide diffusing capacity test, and blood gas analysis.

The median (interquartile range) increase in 6-min walk distance in the intervention group was 40 (31-62) m. Improvement in functional capacity; perception of dyspnea; fatigue; anxiety; peripheral and inspiratory muscle strength; partial arterial oxygen pressure; arterial oxygen saturation; and the symptom, activity, and total scores of the St George Respiratory Questionnaire were significantly greater in the intervention group than in the usual care group at follow-up (P < .05).

Exercise training improves functional capacity, muscle strength, dyspnea, quality of life, anxiety, fatigue, and oxygenation in patients with stage 3 and stage 4 sarcoidosis. Standard treatment of patients with late-stage sarcoidosis should integrate exercise training and pulmonary rehabilitation.
