ObjectiveTo investigate the effect of early rehabilitation physiotherapy on muscle quality and function in critical patients.

MethodsA prospective randomized controlled study was performed. Adult critically ill patients admitted to intensive care unit (ICU) of Anhui Provincial Hospital from October 1st, 2016 to August 31st, 2017 who had been hospitalized for more than 7 days and had acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ ) > 8 were enrolled, and they were divided into treatment group and control group according to random number table method. All patients were given routine treatment, and on this basis, the treatment group was given rehabilitation therapy within 24 hours after admission, including limb active / passive activities, respiratory muscle function training and transcutaneous electrical nerve stimulation, etc. Bedside ultrasound was used to measure the area and cross sectional thickness of left rectus femoris muscle and the cross sectional thickness of middle thigh muscle of patients at 1, 4 and 7 days after treatment; at the same time, the muscle strength of sober patients was evaluated by medical research council (MRC) muscle strength evaluation method, and the mechanical ventilation time, ICU hospitalization time and ICU expenses were recorded.

ResultsForty patients were enrolled in this study, with 20 in each group. Compared with the control group, the difference of left rectus femoris muscle area between 1 day and 4 days, 4 days and 7 days, 1 day and 7 days (cm ²: 0.19±0.02 vs. 0.31±0.19, 0.02±0.01 vs. 0.08±0.05, 0.04±0.02 vs. 0.38±0.23), and the difference in left rectus femoris thickness (cm: 0.01±0.01 vs. 0.14±0.13, 0.03±0.03 vs. 0.16±0.14) and the difference in middle thigh muscle thickness (cm: 0.02±0.02 vs. 0.11±0.09, 0.03±0.02 vs. 0.16±0.12) between 1 day and 4 days, 1 day and 7 days in the treatment group were significantly reduced (all P < 0.01). The MRC strength score in the treatment group was significantly higher than that of the control group at 7 days (52.06±3.52 vs. 47.94±3.96, P < 0.05). The mechanical ventilation time in the treatment group ( n = 15) and the control group ( n = 13) were (138.5±34.5) hours and (185.0±40.9) hours, respectively, and the difference between two groups were statistical significance ( P < 0.05). Compared with the control group, the incidence rate of ICU acquired muscle weakness (ICUAW) in the treatment group was significantly decreased [5.0% (1/20) vs. 40.0% (8/20), P < 0.05], the length of ICU stay was significantly shortened (days: 17.67±4.91 vs. 22.06±5.94, P < 0.05), and the ICU expenses were significantly reduced (ten thousand yuan: 7.53±2.09 vs. 9.55±1.73, P < 0.05).

ConclusionEarly rehabilitation physiotherapy can improve the muscle quality and function in critical patients, and decrease the length of ICU stay.
