Summary of the studies selected for this systematic review on the physiotherapeutic management of the main functional changes after covid-19

Author/Year	Aim	Sample	Intervention	Outcome measures	Results
Li et al. (2022) [14]	To investigate the superiority of a telerehabilitation program for COVID-19 over no rehabilitation	Total: 120 GE: 59 GC: 61	GE: Performed 6-week unsupervised home exercises, delivered via a smartphone app called RehabApp GC: Received short educational instructions at baseline	6-min walk test (6MWT), squat in seconds; lung function assessed by spirometry; HRQoL measured with Short Form Health Survey-12 (SF 12) and mMRC-dyspnoea	This study demonstrated the superiority of TERECO over no rehabilitation for the outcomes analyzed
PEHLIVAN et al., (2022) [15]	examined the effectiveness of some online performance tests on Covid-19 cases in showing the physical performance changes of cases	Total: 21 GE: 11 GC: 10	The EG received breathing exercises, active breathing cycle techniques, range of motion and light aerobic exercises. The GC, on the other hand, received a leaflet with information about basic exercises that can be done at home and about the disease	30-s sit-to-stand test; short-term performance test; Consultation of fatigue on visual analogue scale and dyspnea scale (mMRC)	The authors reported that an online exercise program has positive effects on the physical performance of Covid 19 cases
Nambi et al. (2022) [16]	To compare the clinical and psychological effects of low-intensity and high-intensity aerobic training combined with resistance training in community-dwelling elderly men with symptoms of post-CONVID-19 sarcopenia	Total: 76 G1: 38 G2: 38	G1: Received low-intensity aerobic training for eight weeks G2: received high-intensity aerobic training for eight weeks	Muscle quantity: magnetic resonance imaging; Hand grip strength: portable dynamometer (Camry digital hand dynamometer, EH 101–17);(RM)Quality of life: Sarcopenia and Quality of Life questionnaire (SarQol); Kinesiophobia: The Tampa Scale of Kinesiophobia – 11; perceived exertion (RPE); (Borg scale 6–20) and Likert scale	Low-intensity aerobic training exercises improved clinical and psychological aspects compared to high-intensity aerobic training in older adults with post-COVID-19 sarcopenia
Foged et al. 2021 [17]	Investigate the fidelity, tolerability and safety of three different training protocols high intensity interval (HIIT) in individuals who have been hospitalized due to COVID-19	Total: 10	A randomized crossover trial was performed to compare three supervised HIIT protocols (4 × 4, 6 × 1, 10–20-30) in 10 subjects who were recently discharged after hospitalization for severe COVID-19	Muscle quantity: magnetic resonance imaging; Hand grip strength: portable dynamometer (Camry digital hand dynamometer, EH 101–17);(RM)Quality of life: Sarcopenia and Quality of Life questionnaire (SarQol); Kinesiophobia: The Tampa Scale of Kinesiophobia – 11; perceived exertion (RPE); (Borg scale 6–20) and Likert scale	The authors suggest that individuals who have been hospitalized for severe COVID-19 can safely tolerate the HIIT protocol as a rehabilitation strategy in this context
Giardinia et al. (2022)	To assess balance in patients with post-acute COVID-19 compared with patients with acute exacerbation of chronic obstructive pulmonary disease and healthy subjects	Total: 75 G1: 25 G2: 25 G3: 25	All individuals underwent specific tests to assess balance and, at the end, comparative tests were performed between the groups	Mini Balance Evaluation Systems Test (Mini-BESTest) and Timed Up and Go (TUG),	The study demonstrated that there were similar results between COVID and PwAECOPD. PwCOVID showed a balance deficit in both dynamic and static conditions
