Early post-stroke rehabilitation for upper limb motor function using virtual reality and exoskeleton: equally efficient in older patients.

AIM OF THE STUDY: To evaluate the effectiveness of virtual reality therapy (VRT) Armeo Spring® upper limb exoskeleton (Armeo), in early post-stroke rehabilitation with a focus on the elderly. CLINICAL RATIONALE FOR THE STUDY: Convalescence from a stroke is a complex process driven by a spontaneous recovery supported by multifactorial activation. Novel technology-based rehabilitation methods are being introduced to support brain plasticity. MATERIALS AND METHODS: Using a randomised controlled study design, participants within 30 days after stroke with arm paresis were, in addition to a daily rehabilitation programme, assigned to an intervention group (45 minutes Armeo IG n = 25; mean age 66.5 years) performing VRT, or to a conventional physiotherapy (45 minutes) control group (Armeo CG, n = 25, mean age 68.1 years). Montreal Cognitive Assessment (MoCA), Functional Independence Measure (FIM) and Fugl Mayer Assessment Upper Extremity Scale (FMA-UE) were performed before and after the three-week therapy with 12 therapeutic sessions. Results of participants < 65 and ≥ 65 years old were compared. RESULTS: Paretic upper arm function improved significantly in both the IG and CG groups, the improvement in FMA-UE was significantly higher in the IG compared to the CG (p = 0.02), and patients ≥ 65 years old presented an equal magnitude of improvement in paretic arm function compared to younger patients. CONCLUSIONS AND CLINICAL IMPLICATIONS: Early post-stroke rehabilitation strategies using, in addition to the daily rehabilitation programme, VRT with visual biofeedback is more effective on upper extremity motor performance than conventional physiotherapy, and the effectiveness does not diminish with patient age. This may be a promising addition to conventional physiotherapy in older stroke patients as well as in younger.

Illusory movements for immobile patients with extensive burns (IMMOBILE): A randomized, controlled, cross-over trial.

INTRODUCTION: Patients who have sustained extensive burns frequently exhibit substantial damage to skeletal muscle and associated complications. The rehabilitation of these patients can be challenging due to the nature of the injury and the subsequent complications. Nevertheless, there is a possibility that functional proprioceptive stimulation (illusory movements) may facilitate effective rehabilitation in patients with limited physiotherapy options. Nevertheless, this approach has yet to be tested in patients with burn injuries. MATERIAL AND METHODOLOGY: A prospective, randomised, crossover trial was conducted at a burn centre in a tertiary teaching hospital. The objective was to assess the effects of illusory movements on energy metabolism, insulin sensitivity, and skeletal muscle biology in adult critically ill patients with deep burns covering 30 % or more of the total body surface area. Two 30-minute daily sessions of functional proprioceptive stimulation were administered in addition to the standard physical therapy or physical activity regimen. Subsequently, the patients proceeded to the next stage of the trial, which involved a two-week crossover period. MEASUREMENTS AND MAIN RESULTS: Daily indirect calorimetry and calculation of nitrogen balance. Skeletal muscle biopsies from vastus lateralis for high resolution respirometry and euglycemic clamps to assess whole body glucose disposal were performed three times: at baseline and then fortnightly after each intervention period. The intervention was feasible and well tolerated in both early and late stages of burn disease. It did not change energy expenditure (mean change -33 [95 % CI: -292;+227] kcal .24 h-1, p = 0.79), nitrogen balance (+2.0 [95 % CI: -3.1;+7.1] g N .1.73 m-2 BSA .24 h-1), or insulin sensitivity (mean change of insulin-mediated glucose disposal -0.33 [95 % CI: -1.18;+0.53] mmol.h-1). At the cellular level, the intervention increased the capacity of mitochondria to synthesize ATP by aerobic phosphorylation and tended to increase mitochondrial coupling. Functional capacities of fatty acid oxidation and electron transfer chain complexes I, II, and IV were unaffected. CONCLUSIONS: Compared to physical therapy alone, two daily sessions of functional proprioceptive stimulation in addition to usual physical therapy in patients with extensive burns did not change energy expenditure, insulin sensitivity, nitrogen balance, or energy substrate oxidation. At cellular level, the intervention improved the capacity of aerobic phosphorylation in skeletal muscle mitochondria. Clinical effects remain to be demonstrated in adequately powered trials.

Stretching exercises in managing spasticity: effectiveness, risks, and adjunct therapies.

Spasticity is a component of upper motor neuron disorders and can be seen in neurological conditions like stroke and multiple sclerosis. Although the incidence rate of spasticity is unknown, it can put pressure on the health condition of those with spasticity, and there is no absolute effective way to control it. In the past, stretching exercises were an accessible tool for physical therapists to manage and control spasticity, but opinions on the optimal dose, aftereffects, and mechanism of effects were controversial. Therefore, this article tries to provide an overview of the effectiveness and risks of stretching exercises. Furthermore, there are several adjunct therapies, such as brain stimulation and botulinum injection, that can increase the effectiveness of a simple stretch by increasing cortical excitability and reducing muscle tone and their role is evaluated in this regard. The results of this study propose that several prospective and case studies have demonstrated the benefits of stretching to control spasticity, but it seems that other methods such as casting can be more effective than a simple stretch. Therefore, it is better to use stretching in combination with other therapeutic regimes to increase its effectivity of it.

Can functional electrical stimulation-assisted cycle ergometry replace insulin infusion in patients? A nested substudy in a randomized controlled trial with 6 months' follow-up.

BACKGROUND: Functional electrical stimulation-assisted cycle ergometry (FESCE) can deliver active exercise to critically ill patients, including those who are sedated. Aerobic exercise is known to stimulate skeletal muscle glucose uptake. We asked whether FESCE can reduce intravenous insulin requirements and improve insulin sensitivity in intensive care unit (ICU) patients. METHOD: We performed an a priori-planned secondary analysis of data from an outcome-based randomized controlled trial (NCT02864745) of FESCE-based early-mobility program vs standard of care in mechanically ventilated patients. We analyzed glucose profile, glucose intake, and insulin requirements during ICU stay in all enrolled patients. In a nested subgroup, we performed hyperinsulinemic (120 mIU/min/m2 ) euglycemic clamps at days 0, 7, and 180 (n = 30, 23, and 11, respectively). RESULTS: We randomized 150 patients 1:1 to receive intervention or standard of care. Seventeen (23%) patients in each study arm had a history of diabetes. During ICU stay, patients received 137 ± 65 and 137 ± 88 g/day carbohydrate (P = .97), and 31 vs 35 (P = .62) of them required insulin infusion to maintain blood glucose 8.61 ± 2.82 vs 8.73 ± 2.67 mM (P = .75, n = 11,254). In those treated with insulin, median daily dose was 53 IU (interquartile range [IQR], 25-95) vs 62 IU (IQR, 26-96) in the intervention and control arm, respectively (P = .44). In the subgroup of patients undergoing hyperglycemic clamps, insulin sensitivities improved similarly and significantly from acute and protracted critical illness to 6 months after discharge. CONCLUSION: The FESCE-based early-mobility program does not significantly reduce insulin requirements in critically ill patients on mechanical ventilation.
