Effect of 12-month rehabilitation with low loading program on chronic respiratory disease.

[Purpose] The purpose of this study was to examine the effect of 12-month rehabilitation with low loading program on chronic respiratory disease. [Subjects and Methods] Twelve patients with chronic respiratory disease participated in this study, in which the effect of long-term rehabilitation for 12 months was assessed. Nine patients had chronic obstructive pulmonary disease, two had asthma, and one had interstitial pneumonia. In all patients, symptoms, lower-extremity strength, walking distance, activities of daily living, and quality of life were investigated to examine the effect of respiratory rehabilitation. [Results] After 12 months, the isometric knee extension strength and weight-bearing index both showed a significant increase. [Conclusion] The findings of this study suggested that improvement in lower-limb muscle strength can be achieved through long-term intervention, and indicated the validity of repetitive standing and walking exercises.
