Clinical Trial Summary

The aim of this study is to assess the clinical effectiveness of the RehaARM-robot and to determine the feasibility of including robotic therapy in daily rehabilitation programmes, after stroke. Additionally, we aim to investigate the acceptance of this intervention from patients and therapists. A total of 10 patients will be recruited in this study, all the patients will receive 1 hour of standard therapy together with 45 min of robot therapy every day. The robot therapy will last 45 minutes, for 15 consecutive days within a maximum period of four weeks. Additional 15 minutes are required for placing surface electrodes on the shoulder and patient preparation. The study will include passive and active shoulder training of four movements: Horizontal abduction/adduction, abduction/adduction, internal/external rotation and flexion/extension. The passive part lasts 10 minutes and the active part 35 minutes.

Eligibility

Inclusion Criteria:

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Shoulder active range of movement (ROM-S)	Active range improvement for shoulder abduction and flexion are measured using the Tyromotion Pablo System.	3 weeks (15 sessions)
Other	• Average amount of active task repetitions of a sequence of motor tasks using the robot during a 1-hour therapy treatment.	A higher number of repetitions is a paramount for neuroplasticity. The ability of subjects to execute a larger of number of motor task repetitions with the robot after the treatment is measured.	3 weeks (15 sessions)
Other	• Smoothness of the torque (i.e. Number of peaks of the torque, [n]) for a sequence of motor tasks using the robot during a 1-hour therapy treatment .	Smoothness is a measure of human movement coordination. Improvement of smoothness after the treatment is measured.	3 weeks (15 sessions)
Other	• Average magnitude of the muscle activation during the active phase normalized by duration of the active phase (magnitude/time) for a sequence of motor tasks using the robot during a 1-hour therapy treatment.		3 weeks (15 sessions)
Other	• Average similarity between the muscle (synergy) modules of the paretic arm and the muscle modules of the right arm of healthy subjects for a standard sequence of motor tasks using the robot during a 1-hour therapy treatment		3 weeks (15 sessions)
Primary	Fugl-Meyer Assessment scale - Upper Extremity (FMA-UE)	Motor function of the upper limb is measured by means of the Upper Extremity Motor Assessment of the Fugl-Meyer Assessment Scale.	3 weeks (15 sessions)
Secondary	Functional Independence Measure (FIM)	FIM is an 18-item scale that assesses patient's disability and medical rehabilitation functional outcome (A total of 126 points).	3 weeks (15 sessions)
Secondary	Reaching Performance Scale (RPS)	It assesses the ability of subjects to reach an object (a cone). The cone is placed at a 4-cm distance and after at a 30-cm distance from the subject. The subject is asked to reach and grab the cone if possible. The observer evaluates the quality of reaching instead of the grip strength ( A total of 36 points).	3 weeks (15 sessions)
Secondary	Modified Ashworth Scale (MAS) of five muscles	Spasticity is measured using the MAS of five muscles: Pectoralis major, biceps, wrist flexors, flexor digitorum superficialis, flexor digitorum profundus (Total of 20 points).	3 weeks (15 sessions)
Secondary	Nine Hole Pegboard Test (NHPT)	It measures the dexterity of the hand. Patient should insert 9 pins in the board. There are 9 pins. The number of pins inserted in 50 min are registered or if the patient inserted 9 pins, then the time is registered.	3 weeks (15 sessions)
