Physiotherapeutic intervention in patients with sequels of COVID-19

INTERVENTION: E02.779 E02.779.474 G11.427.410.698.277 This is a three‐arm, double‐blind, randomized controlled clinical trial. The target sample will be 43 individuals with post‐COVID‐19 syndrome. Experimental group 1: 14 individuals with post‐COVID‐19 syndrome will receive intervention through conventional rehabilitation, which will consist of 05 phases (Phase 1: warming up on an ergometric bicycle for 5 minutes; Phase 2: walking on a treadmill for 10 to 20 minutes; Phase 3: resistance exercises on gym machines for upper and lower limbs and trunk; Phase 4: balance exercises, such as mini squats and ankle flexions, free on the ground that will progress to destabilizing platforms, such as balance pad and disc‐shaped balance pad; Phase 5: slow and sustained muscle stretching for 30 to 60 seconds of the main muscles of the upper and lower limbs and trunk), each session lasting between 40 and 60 minutes; two weekly sessions will be held for eight weeks, totaling 16 sessions. Experimental group 2: 15 individuals with post‐COVID‐19 syndrome will receive intervention through the Pilates Method in the solo modality and with specific equipment, such as the Reformer, the Ladder Barrel, the Chair and the Cadillac, with a total of 49 exercises (which will be performed in 1 series of 3 to 10 repetitions, depending on the evolution of the treatment plan) distributed in 5 phases (Phase 1: Pre‐Pilates/Warm‐up, which consists of 07 exercises to prepare breathing, body and of the mind for the following exercises; Phase 2: MatWork/MatPilates, which consists of 18 exercises performed in the ground modality aimed at the upper and lower limbs and trunk; Phase 3: Reformer, which consists of 06 exercises performed on this device aimed at upper and lower limbs and trunk; Phase 4: Chair, which consists of 06 exercises performed on this device aimed CONDITION: C01.748.610.763.500 SARS‐CoV‐2 PRIMARY OUTCOME: It is expected to find an improvement in parameters related to physical health, which are pain, spinal flexibility, rib cage expansion, peripheral muscle strength, ventilatory muscle strength, lung capacity and volumes, functional capacity and physical conditioning, verified by through eight evaluation protocols, namely, the visual analogue scale, the spinal flexibility tests, the thoracic cirtometry, the manual dynamometry, the manovacuometry, the microspirometry, the sitting and standing test from a chair and the walking test of six minutes, respectively, from the verification of a variation of at least 5% in the pre‐ and post‐intervention measurements. SECONDARY OUTCOME: It is expected to find an improvement in the parameters related to mental health, which are self‐perception of health, quality of life, quality of sleep and symptoms of depression, anxiety and stress, verified through three evaluation protocols, namely, the Medical Outcomes Study 36 – Item Short‐Form Health Survey, the Pittsburgh Sleep Quality Inde Xand the Depression Anxiety Stress Scales‐21, respectively, based on the verification of a variation of at least 5% in the pre‐ and post‐intervention measurements. INCLUSION CRITERIA: Volunteers referred to the University of Passo Fundo Physiotherapy Service; age between 20 and 80 years; both genders; presence of symptoms related to SARS‐CoV‐2 infection and persistent for 12 weeks after diagnosis of COVID‐19
