Summary

Rehabilitation after stroke often employs Robot and Allied Digital Technologies (RADTs), yet evidence on their effectiveness remains inconclusive due to study heterogeneity and limited sample sizes. This multicentre randomized controlled pragmatic trial aims at comprehensively and accurately assessing the effectiveness of rehabilitation mediated by RADTs after a stroke, compared to traditional rehabilitation, also considering economic sustainability.

Detailed description

The aim of this study is to evaluate, in a pragmatic trial on a large sample of patients who have experienced a stroke within the six months prior to enrollment, the effectiveness of a multimodal treatment using robotics and advanced technologies compared to traditional multimodal treatment, in the recovery of activities of daily living. Primary Objective: To demonstrate, in a population of subacute stroke patients, the non-inferiority of a rehabilitation treatment integrated with robotic and/or technological devices compared to traditional rehabilitative treatment in the recovery of activities of daily living. Secondary Objectives: * To demonstrate the superiority of rehabilitative treatment integrated with robotic and/or technological devices compared to traditional rehabilitation treatment in the recovery of activities of daily living, should non-inferiority be demonstrated; * To compare the improvements between two groups in all targeted domains (upper limb sensorimotor abilities; lower limb sensorimotor abilities and gait; balance; cognitive abilities), in accordance with the International Classification of Functioning, Disability, and Health (ICF); * To analyze the neurophysiological parameters and factors involved in neuroplasticity processes; * To compare the time pattern of manual dexterity and walking performance recovery in the two groups; * To assess the effects of the rehabilitation treatment in terms of daily life activities and quality of life through medium-term follow-up; * To evaluate the acceptability and usability of the rehabilitative treatment integrated with robotic and/or technological devices for the patient, their family, and the healthcare practitioner; * To create a predictive model capable of forecasting the effectiveness of robotic and technological treatment in subjects after a stroke, based on a detailed description of the patient at baseline (using demographic data and clinical picture at admission); * To assess the economic sustainability of the rehabilitative treatment integrated with robotic and/or technological devices for the patient, payer, and society, through the creation of a model for the assessment and prediction of cost-effectiveness, cost-utility, and, for the healthcare system, a Budget Impact Analysis, and related sensitivity analyses. The study employs a multicenter, multimodal, randomized, controlled, parallel-group (1:1) interventional design with blinded assessors, following a pragmatic approach. It will be conducted across multiple clinical centers involved in a national research initiative, encompassing both outpatient and inpatient settings. Randomization will be centralized and stratified by clinical center, latency, and clinical setting (inpatients or outpatients). The sample size (596 patients) was determined considering the following, with respect to the primary outcome (the change in the modified Barthel Index): (a) the non-inferiority of robotic treatment compared to traditional treatment; (b) a power of 80%; (c) a non-inferiority margin of 5 points; (d) a bilateral 95% confidence interval; (e) a standard deviation of the primary outcome of 20 points. Considering these parameters, a sample size of 506 patients (253 per group) is obtained. Additionally, considering a dropout rate of 15%, a total sample size of 596 patients is obtained. The same sample size is sufficient to also demonstrate the potential superiority of robotic treatment. In fact, considering a significance level of 5%, a power of 80%, a minimal clinically important difference of the scale of 9.25 points, a standard deviation of 20 points, and a dropout rate of 15%, a total of 178 patients are required for demonstrating superiority. The experimental group will receive rehabilitation using RADTs within a new organizational model, where two physical therapists supervise four to six patients. In the control group, patients will undergo individual traditional rehabilitation, maintaining a 1:1 patient-to-therapist ratio. In both groups, patients will undergo comprehensive rehabilitation treatment, targeting the following domains: a) upper limb sensorimotor abilities; b) lower limb sensorimotor abilities and gait; c) balance; d) cognitive abilities. The primary outcome is to demonstrate non-inferiority in activities of daily living as measured by the modified Barthel Index. Should non-inferiority be established, the study will then evaluate the potential superiority of RADTs in activities of daily living. All participating centers will follow a standardized operating procedure regarding treatment and outcome assessment to ensure consistency across all sites. Data will be systematically collected using the REDCap (Research Electronic Data Capture) platform.

Interventions

Type	Name	Description
OTHER	robotic rehabilitation	Treatment will occur in a gym equipped with devices for all the domains, with two physiotherapists supervising groups of 4 to 6 patients, depending on their clinical severity. Patients will undergo a total of 25 sessions, each lasting 45 minutes, with the following frequency: * 5 times a week for 5 weeks, for inpatients; * 3 times a week for 8.3 weeks, for outpatients.
OTHER	traditional rehabilitation	A physiotherapist-to-patient ratio of 1:1 is provided for the treatment in all participating centres. Patients will undergo a total of 25 sessions, each lasting 45 minutes, with the following frequency: * 5 times a week for 5 weeks, for inpatients; * 3 times a week for 8.3 weeks, for outpatients.
