Functional outcomes of protocol-based rehabilitation for patients with coronavirus disease 2019 in an acute care setting.

Objectives: To examine the functional outcomes of patients with coronavirus disease 2019 (COVID-19) who underwent a new protocol-based rehabilitation program. Methods: In this retrospective cohort study, we enrolled patients who were hospitalised in a university hospital in Japan because of COVID-19 from 1st September, 2020-5th July, 2021. The primary outcome was the Functional Independence Measure (FIM) subtotal score for motor items at discharge. The secondary outcomes included the FIM cognitive subtotal score, length of hospital stay, rehabilitation period, total rehabilitation time, final rehabilitation protocol level, and discharge destination. Results: Of the 78 enrolled patients (49 men; mean age [standard deviation], 70.3 [13.9] years), 24 died (30.8%) during hospitalisation. Disease severity was classified as mild, moderate I, moderate II, and severe in 1, 6, 41, and 30 patients, respectively. The FIM motor subtotal score differed significantly among groups for all participants (p=0.027). Post hoc analysis revealed that the FIM motor subtotal score in the severe group was significantly lower than that in the moderate II group (p=0.030). Conclusions: Disease severity significantly affected patients' functional outcome for COVID-19 at discharge. Our protocol-based program provides a benchmark for COVID-19 rehabilitation in an acute care setting.

THE EFFECT OF IN-BED LEG CYCLING EXERCISES ON MUSCLE STRENGTH IN PATIENTS WITH INTENSIVE CARE UNIT-ACQUIRED WEAKNESS: A SINGLE-CENTER RETROSPECTIVE STUDY.

Objective: To examine the effect of in-bed leg cycling exercise on patients with intensive care unit-acquired weakness (ICU-AW). Design: Single-center retrospective study. Subjects/Patients: Patients admitted to the ICU between January 2019 and March 2023 were enrolled in the ergometer group, and those admitted to the ICU between August 2017 and December 2018 were enrolled in the control group. Methods: The ergometer group performed in-bed leg cycling exercises 5 times per week for 20 min from the day of ICU-AW diagnosis. Furthermore, the ergometer group received 1 early mobilization session per day according to the early mobilization protocol, whereas the control group received 1 or 2 sessions per day. The number of patients with recovery from ICU-AW at ICU discharge and improvement in physical functions were compared. Results: Significantly more patients in the ergometer group recovered from ICU-AW than in the control group (87.0% vs 60.6%, p = 0.039). Regarding physical function, the ergometer group showed significantly higher improvement efficiency in Medical Research Council sum score (1.0 [0.7-2.1] vs 0.1 [0.0-0.2], p < 0.001). Conclusion: In-bed leg cycling exercise, in addition to the early mobilization protocol, reduced the number of patients with ICU-AW at ICU discharge.

Measuring and Monitoring Skeletal Muscle Mass after Stroke: A Review of Current Methods and Clinical Applications.

OBJECTIVES: Muscle mass at admission is important to survive stroke, and stroke-induced sarcopenia is a serious problem because of its poor prognosis. Muscle mass measurement and monitoring are essential for appropriate rehabilitation and nutrition management. However, few reviews are available about the muscle mass measurement and monitoring after stroke. MATERIAL AND METHODS: Several methods are used to assess skeletal muscle mass in stroke, such as computed tomography (CT), ultrasound, bioelectrical impedance analysis, dual-energy X-ray absorptiometry, biomarkers, and anthropometrics. We summarized the current methods and clinical applications in stroke. RESULTS: In stroke, a head CT is used to estimate muscle mass by measuring the temporal muscle. However, it can be conducted retrospectively due to radiation exposure. After stroke, limb muscle atrophy and diaphragm dysfunction are observed using ultrasound. However, ultrasound requires an understanding of the methods and skill. A bioelectrical impedance analysis can be used to assess muscle mass in patients after a stroke unless they have dynamic fluid changes. Dual-energy X-ray absorptiometry is used for follow-up after hospital discharge. Urinary titin N-fragment and serum C-terminal agrin fragment reflect muscle atrophy after stroke. Anthropometrics may be useful with limited resources. CONCLUSIONS: We summarized the features of each measurement and proved the recent evidence to properly measure and monitor skeletal muscle mass after stroke.
