Natural Course of Muscular Strength, Physical Performance, and Musculoskeletal Symptoms in Hospitalized Patients With COVID-19.
To investigate the course of muscle strength, musculoskeletal symptoms and physical performance over time in hospitalized COVID-19 patients, and their relation with disease severity at admission.
Prospective cohort study.
Pandemic clinic of Gazi University Hospital, Ankara, Turkey.
76 adult COVID-19 patients (aged >18 years) were enrolled in the study between March 2021 and May 2021 (N=76). The participants were grouped as "mild," "moderate," and "severe" according to clinical and radiological findings.
The fraction of inspired oxygen (FiO2), oxygen saturation (SpO2), hand grip strength (HGS), 5-times sit and stand test (5XSTS), modified Borg scale at rest (mBorg-rest), modified Borg scale during activities of daily living (mBorg-ADL), Barthel index, and visual analog scale for myalgia (myalgia-VAS) values were recorded on the first day of hospitalization and in the first, third, and 12th weeks. Outcome measures were compared between disease severity groups. In addition, the changes in these outcome measures over time were also examined.
There were 15 (19.7%) participants in the mild, 20 (26.3%) in the moderate, and 41 (53.9%) in the severe groups. At the baseline evaluation, SpO2 (P<.001), FiO2 (P<.001), 5XSTS (P=.002), mBorg-rest (P=.016), and mBorg-ADL (P<.001) were different in 3 groups, but there were no differences for HGS, Barthel index, and myalgia-VAS score. HGS, 5XSTS, myalgia-VAS, and mBorg-ADL scores improved significantly over time in all the groups (P<.001, P≤.001, and P<.001, respectively). At the end of 12 weeks, only 5XSTS was different between the groups. 5XSTS was significantly longer in the severe group (P=.010).
Although significant improvement was observed in the muscle strength, physical performance, and musculoskeletal symptoms of patients with COVID-19 over time, the physical performance of these patients did not reach normal standards. We conclude that post-COVID-19 rehabilitation programs are needed to optimize the physical performance of the patients.

Long COVID: rheumatologic/musculoskeletal symptoms in hospitalized COVID-19 survivors at 3 and 6 months.
To document the detailed characteristics including severity, type, and locations of rheumatic and musculoskeletal symptoms along with other COVID-19 persistent symptoms in hospitalized COVID-19 survivors at 3 and 6 months.
In this extension cohort study, two telephone surveys at 3 and 6 months following the hospitalization were carried out. In these telephone surveys, participants were asked regarding their symptoms through a previously designed standard questionnaire.
At 3 months, 89.0% of survivors had at least one symptom, 74.6% had at least one rheumatic and musculoskeletal symptom, and 82.1% had at least one other COVID-19 symptom. At 6 months, 59.6% of survivors had at least one symptom, 43.2% had at least one rheumatic and musculoskeletal symptom, and 51.2% had at least one other COVID-19 symptom. Regarding the rheumatic and musculoskeletal symptoms, 31.6% had fatigue, 18.6% had joint pain, and 15.1% had myalgia; and regarding the other-COVID-19-symptoms, 25.3% had dyspnea, 20.0% had hair loss, and 17.2% sweat at 6 months. In an adjusted model, female patients were more likely to have fatigue (OR: 1.99, 95% CI: 1.18-3.34), myalgia (3.00, 1.51-5.98), and joint pain (3.39, 1.78-6.50) at 6 months.
Approximately 3 in 5 patients had at least one symptom with ≈2 in 5 patients had at least one rheumatic and musculoskeletal symptom. Fatigue, joint pain, and myalgia were the most frequent rheumatic and musculoskeletal symptoms. Joint pain and myalgia were mostly widespread. This information guide rheumatologists to understand the nature and features of persistent rheumatic and musculoskeletal symptoms in hospitalized COVID-19 survivors and may contribute to better management of these individuals. Key Points • Approximately 3 in 5 patients had at least one symptom with ≈2 in 5 patients had at least one rheumatic and musculoskeletal symptom at 6 months • Fatigue, joint pain, and myalgia were the most frequent rheumatic and musculoskeletal symptoms followed by back pain, low back pain, and neck pain • Dyspnea, hair loss, and sweat were the most frequent other-COVID-19-symptoms.

Grip strength as a predictor of disease severity in hospitalized COVID-19 patients.
Grip strength is one of the main components for the physical functioning in sarcopenia and physical frailty.
To explore the role of grip strength measurement at admission for predicting disease severity in COVID-19.
Demographic data, smoking status, comorbidities, COVID-19 related symptoms, grip strength, laboratory and computed tomography (CT) findings at admission were all noted. Using a Smedley hand dynamometer, the maximum grip strength value (kg) after three measurements on the dominant side was recorded. Low grip strength was defined as two standard deviations below the gender-specific peak mean value of the healthy young adults (<32 kg for males, <19 kg for females). Patients were categorized into three groups according to clinical and CT findings. Severe illness group had pneumonia with a respiratory rate >30/min, oxygen saturation ≤90%, or extensive lung involvement in CT. Moderate illness group had pneumonia with CT score ≤11. Mild illness group had normal CT findings.
The study population included 312 patients (140 F, 172 M). The distribution of mild, moderate and severe disease groups were 36.9%, 51.0% and 12.2%, respectively. Cough, fever, dyspnea, hypertension, obesity, cardiovascular disease (CVD) and chronic obstructive pulmonary disease (COPD) were most frequent, and C-reactive protein (CRP), ferritin, D-dimer, and neutrophil levels were highest in the severe group (all p<.05). Absolute grip strength values were lowest and the frequency of having low grip strength were highest in the severe group (both p<.01). Since we found that the significant differences were stemming from the severe group, we combined the mild and moderate group as non-severe, and compared severe vs. non-severe groups with binary logistic regression analyses. When age, gender, body mass index, smoking status, presence of comorbidities and low grip strength, and abnormal laboratory findings were taken into analyses; age (odds ratio [OR]: 1.054 [95% confidence interval (CI): 1.020-1.089]), obesity (OR: 2.822 [95% CI: 1.143-6.966]), COPD (OR: 5.699 [95 %CI: 1.231-26.383]), CRP level (OR: 1.023 [95% CI: 1.010-1.036]) and low grip strength (OR: 3.047 [95% CI: 1.146-8.103]) were observed to be independent predictors for severe COVID-19 disease (all p<.05).
In addition to the well-known independent risk factors (i.e. age, obesity, COPD, and CRP level), low grip strength independently increased (about three times) the severity of COVID-19.
