Table 1.

Overview of an intervention session in the experimental and control groups according to the Template for Intervention Description and Replication (TIDieR) checklist and guide. Both groups will receive 25 sessions of rehabilitation treatment for three weeks (5 sessions/week).

TIDieR Item	Experimental Group	Control Group	Experimental and Control Groups
1. Name	Upper limb rehabilitation through Armeo Power exoskeleton	Upper limb rehabilitation through conventional therapy	Passive, active-assisted, and active exercises addressed for shoulder, arm, and hand motor rehabilitation	Exercises for muscle strength	Stretching exercises	Functional activity training
2. Why	To improve upper limb motor functioning	To improve upper limb motor functioning	To improve mobility and muscle activation, to preserve the passive range-of-motion (ROM), and to prevent contractures and spasticity	To improve muscle strength	To prevent muscle retraction/contractures and spasticity	To improve autonomy in activities of daily living
3. What (materials)	Exoskeleton with auditory and visual bio-feedback	Proprioceptive and therapy objects	With or without continuous shoulder and/or elbow passive motion	Soft weights, elastic resistance bands, and therapy objects assisted by physiotherapist	Manually assisted by physiotherapist	Objects typically present in the home for activities of daily living
4.What (procedures)	The exoskeleton will be donned and customized on the patient and they will be asked to interact with it in an assist-as-needed modality, receiving a real-time visual biofeedback and interacting with serious video-games.During the first session, the device will be adjusted to the patient’s arm size and the angle of suspension. The working space and the exercises will be selected once the upper limb has been fitted with the system. The selection of personalized exercises is based on the motor skills of each patient and the difficulty can be gradually increased during training.	The exercises will consist of passive, active-assisted, and active exercises for the shoulder, elbow, and wrist in a seated position	Gradual increasing the degree of flexion and extension or a physical therapist will passively mobilize the joints into flexion and extension	The exercises will consist of isometric, isotonic contraction of the upper limb muscles	The exercises will consist of stretching the upper limb muscles	The patients will follow training on activities of daily living. The patient will perform training with assistance, with aids, or autonomously.
5. Who provided	Senior physical therapists who are experts in neurorehabilitation					Occupational Therapists
6. How	An individual face-to-face treatment session
7. Where	Rehabilitation gym in an intensive subacute rehabilitation hospital
8. When and how much	45 + 60 (occupational therapy; functional therapy (trunk control, standing, and walking training), speech therapy, and/or neuro-cognitive therapy)
9. Tailoring			The exercise will be tailored to participants’ goals, current abilities, and preferences, also considering the patient’s point of view
10. Modifications	The exercises difficulty will be increased gradually session by session, depending on current progress, level of pain, and ability.
11. How well (planned)	Organizing periodical updating meetings with the team of physical therapists and other clinicians involved in the study to conduct the treatments in the most homogeneous way possible and to address any problems and/or critical points that may be encountered during the trial execution.
12. How well (actual)	Physical therapist delivering the treatments will register how many sessions a patient attended and completed.
