Effectiveness of adapted physical activity and therapeutic exercise programme in improving chronic fatigue syndrome in long COVID, delivered via hospital-based rehabilitation versus telerehabilitation.

Publication date: Jun 17, 2026

Long COVID is a prevalent condition characterised by pain, fatigue, disability, and a multitude of health issues. There are various treatment options for managing long COVID symptoms, including non-pharmacological interventions like physiotherapy and rehabilitation, which can be effectively delivered either in institutional care settings or via telerehabilitation. This three-arm randomised controlled trial included 145 participants selected from a population-based cohort in eight administrative divisions in Bangladesh. Participants aged 18 and above diagnosed with chronic fatigue syndrome (CFS) secondary to long COVID were included and history of fatigue, cardiovascular, neuro-musculoskeletal, or respiratory diseases, or red flag signs were excluded. Participants were allocated to three groups: hospital-based rehabilitation (HBR), telerehabilitation (TR), or a home programme (HP). Interventions consisted of an individualised exercise programme. The HBR and TR groups received physiotherapist-supervised sessions with sessions lasting 45 min, twice weekly for 8 weeks. And the HP group performed exercises independently following structured instruction. Fatigue, the primary outcome, was measured using the Chalder fatigue scale, while secondary outcomes were quality of life measured using the 36-item Short Form Survey (SF-36), disability-adjusted life years (DALYs), and cardiorespiratory parameters (blood pressure, pulse rate, oxygen saturation, and lung capacity). Between 1st July 2023 and 31st December 2023, 145 participants were enrolled, with a mean age of 46. 1 +/- 6. 7 years. After 8 weeks of intervention, the among-group within-group comparison showed a significant difference in fatigue level (HBR: P
