Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Loss of arm function is a common and distressing consequence of stroke. Neurotechnology-aided rehabilitation could be a promising approach to accelerate the recovery of upper limb functional impairments. This multicentre randomized controlled trial is aimed at assessing the efficacy of robot-assisted upper limb rehabilitation in subjects with sub-acute stroke following a stroke, compared to the traditional upper limb rehabilitation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Stroke is the most common cause of complex adult disability in high-income countries \[1\]. Loss of arm function affects 69% of people who have a stroke \[2\]. Only 12% of people with arm weakness at the onset of stroke make a full recovery \[3\]. Improving arm function has been identified as a research priority by stroke survivors, carers, and health professionals who report that current rehabilitation pays insufficient attention to arm recovery \[4\].

Robot-assisted training enables a greater number of repetitive tasks to be practiced in a consistent and controllable manner. Repetitive task training is known to drive Hebbian plasticity, where the wiring of pathways that are coincidently active is strengthened \[5, 6\]. A dose of greater than 20 h of repetitive task training improves upper limb motor recovery following a stroke \[7\] and, therefore, robot-assisted training has the potential to improve arm motor recovery after stroke. We anticipate that Hebbian neuroplasticity, which is learning dependent, will operate regardless of the post-stroke phase. We, hereby, describe the protocol for a multicentre randomized controlled trial to determine whether robot-assisted training improves upper limb function following a stroke in the sub-acute stage.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental Group (EG)

The experimental group (EG), in addition to the standard treatment, will perform one session per day, each lasting 40 minutes, with the Armeo Power robotic system for upper limb rehabilitation. Each subject will perform a total of 25 ± 3 treatment sessions with a frequency of 5 times a week for 5 weeks.

Group Type EXPERIMENTAL

Exoskeleton-Assisted Upper Limb Rehabilitation

Intervention Type DEVICE

The patients will be undergone 25+/-3 Armeo-P training sessions, each lasting 40 minutes (i.e. five times a week for five consecutive weeks). During the first session, the device should be adjusted to the patient's arm size and the angle of suspension. The working space and the exercises will be selected once the UL has been fitted with the system. The selection of personalized exercises will be based on the motor skills of each patient and the difficulty can be gradually increased during training. In particular, a course of exercises has been defined in which the difficulty (suspension rate; the level of assistance; the complexity of movement (1D, 2D, 3D)).

The physiotherapist will choose the modality based on the patient's motor skills (standardized personalized training).

Control Group (CG)

The control group (CG), in addition to the standard routine rehabilitation treatment, will follow 40 minutes of conventional upper limb rehabilitation. Each subject will perform a total of 25 ± 3 conventional upper limb treatment sessions with a frequency of 5 times a week for 5 weeks.

Group Type ACTIVE_COMPARATOR

Traditional Upper Limb Rehabilitation

Intervention Type OTHER

The control group (CG), in addition to the conventional treatment based on the routine rehabilitation program, will follow 25+/-3 sessions of traditional upper limb rehabilitation (i.e. five times a week for five consecutive weeks). Each session will consist of passive, active-assisted, and active exercises addressed for shoulder, arm and hand motor rehabilitation.
