OBJECTIVE: Lymphedema is a chronic, progressive disease that results from the accumulation of protein-rich fluid in the interstitial tissue spaces. The aim of this study is to assess disease severity, respiratory muscle strength, respiratory functions, pectoralis minor muscle shortening, functionality, and quality of life(QoL) in patients with upper limb lymphedema (ULL), and to compare these findings with healthy controls. METHODS: The disease severity was assessed using the Stillwell classification system
respiratory muscle strength was measured through maximum inspiratory and expiratory intraoral pressures (MIP, MEP, respectively)
respiratory functions were evaluated with a spirometer
muscle length of pectoralis minor (PM) was measured with a tape measure
functionality was assessed using the Disabilities of the Arm, Shoulder and Hand (DASH)
and QoL was evaluated with the Lymphedema Quality of Life Questionnaire - Arm (LYMQOL-Arm). The participants were divided into 2 groups, patients with ULL in Group 1
the healthy individuals were included in Group 2. RESULTS: The group 1 had lower values for MIP, MEP, FEV CONCLUSION: Patients with ULL were found to be impaired in respiratory muscle strength, respiratory function tests, functionality and muscle length of PM compared to healthy individuals.
