PEMOCS: Evaluating the effects of a concept-guided, PErsonalised, MOtor-Cognitive exergame training on cognitive functions and gait in chronic Stroke-study protocol for a randomised controlled trial.

BACKGROUND: Many stroke survivors remain with residual cognitive and motor impairments despite receiving timely acute and sub-acute rehabilitation. This indicates that rehabilitation following stroke should be continuous to meet the needs of individual stroke patients. Both cognitive and motor functions are essential for mastering daily life and, therefore, should be aimed at with rehabilitation. Exergames, motor-cognitive exercises performed using video games, are an auspicious method to train both motor and cognitive functions and at the same time may foster the long-term motivation for training. This study aims to assess the effect of concept-guided, personalised, motor-cognitive exergame training on cognitive and motor functions in chronic stroke survivors. METHODS: This study is a single-blinded, randomised controlled trial. Assessments are performed at baseline, after a 12-week intervention, and at a 24-weeks follow-up. Chronic stroke patients (≥ 18 years old, ≥ 6 months post-stroke) able to stand for 3 min, independently walk 10 m, follow a two-stage command, and without other neurological diseases apart from cognitive deficits or dementia are included. Participants in the intervention group perform the exergame training twice per week for 30 (beginning) up to 40 (end) minutes additionally to their usual care programme. Participants in the control group receive usual care without additional intervention(s). Global cognitive functioning (total Montreal Cognitive Assessment (MoCA) score) is the primary outcome. Secondary outcomes include health-related quality of life, specific cognitive functions, single- and dual-task mobility, and spatiotemporal gait parameters. The target sample size for this trial is 38 participants. Linear mixed models with the post-outcome scores as dependent variables and group and time as fixed effects will be performed for analysis. DISCUSSION: Superior improvements in global cognitive functioning and in the abovementioned secondary outcomes in the intervention group compared to the control group are hypothesised. The results of this study may guide future design of long-term rehabilitation interventions after stroke. TRIAL REGISTRATION: ClinicalTrials.gov (NCT05524727). Registered on September 1, 2022.

Effects of an outpatient physical exercise program on hematopoietic stem-cell transplantation recipients: a randomized clinical trial.

Patients who undergo hematopoietic SCT (HSCT) often experience physical and psychological problems, even long after treatment has been completed. This study was performed to evaluate the effects of a 12-week outpatient physical exercise (PE) program, incorporating aerobic and strength exercises, as compared with a usual care control condition on patients' physical performance and psychosocial well-being. Patients who had completed HSCT up to 6 months earlier were randomly assigned to a supervised PE program (n=64) or a usual care control group (n=67). Primary outcomes were quantified physical performance and self-reported physical functioning. Secondary outcomes were body composition measurement, quantified walking activity and patient-reported outcomes (physical activity, fatigue and health-related quality of life). Assessments were at baseline, immediately after program completion and at 3-month follow-up. Significant intervention effects were observed at both posttreatment and follow-up on physical performance measures. No other outcomes yielded statistically significant group differences. PE should be considered in the management of HSCT recipients to improve physical performance after discharge from the hospital. Further research is needed to determine how the program can be enhanced so that improved physical performance also translates into improved physical and psychosocial functioning in daily life.
