After COVID-19, musculoskeletal pain, anxiety, and sleep problems can continue. The study aimed to investigate the effects of strengthening and relaxation exercises on pain, anxiety, and sleep quality. The study was performed at Gaziosmanpaşa Education and Research Hospital with 76 post-covid patients that were randomized into experimental and control groups. Experimental group patients performed strengthening and relaxation exercises 3 times a week for 8 weeks. Control group patients did not perform any program. All participants were assessed with McGill Pain Scale short form (SFMPQ), short-form 36 (SF-36), and Pittsburgh sleep quality index (PSQI) before and after the study.
