Investigation of the Relationship of Kinesiophobia and Physical Activity Level with Dyspnea, Muscle Strength, and Proprioception in Patients with Chronic Obstructive Pulmonary Disease: A Retrospective Study

Purpose: This study aimed to examine the relationship of kinesiophobia (fear of movement) and physical activity level with dyspnea, peripheral muscle strength and proprioceptive acuity in patients with chronic obstructive pulmonary disease (COPD). Metarial and Methods: A total of 36 COPD patients (mean age: 66.94 ± 10.40 years) were included in this retrospective cross-sectional study. Within the scope of the purpose of the current study, the patients’ demographics, respiratory symptoms, as well as clinical characteristics such as kinesiophobia level, physical activity level, dyspnea severity, peripheral muscle strength, and proprioceptive level were recorded from the patient file. Results: The majority of the patients (72.2%) were GOLD Stage 2. The patients had a high level of kinesiophobia (≥ 37 points), low physical activity level, prolonged sitting time, and high dyspnea severity (mMRC ≥ 2). In addition, the quadriceps, iliopsoas and tibialis anterior muscle strength of the patients were 7.47±2.40 kg, 7.34±2.06 kg and 8.93 (7.10/9.60) kg, respectively, and the patients’ knee proprioception (degree of deviation from the target angle) were 3.50 (1.33/4.16) degrees. Kinesiophobia level showed a significant relationship with physical activity level and sitting time (p
