Description of intervention(s) / exposure
ARM1:
Intelligent Stroke Rehabilitation System is a device which assists rehabilitation doctors and therapies to do functional assessment for the hemiplegic upper limb of stroke patients, and also provides equipment for rehab exercises.
It consists of a doctor station and a patient station. The doctor station is operated by the therapist in hospital and includes system software and data memory. Through the system software, therapists can perform the following tasks on computer: storage and query of patient information, evaluation of patient upper limb function, movement selection, and exercise parameter settings. The therapist stores the training program into the data memory for patients. The patient station is used by patients in the hospital treatment room or at home and includes: data acquisition, an infrared reflective garment, and infrared reflective glove. During rehabilitation training, the patient puts the infrared reflective garment and the infrared reflective glove on the affected upper limb, standing or sitting on the direction of the data acquisition unit at a certain distance. The data memory is inserted into the data acquisition unit which is connected with a TV to show the training system interface. Body positioning and screen touching training are based on system prompts. After finishing the training, the patient turns off the data acquisition unit, and takes off the infrared reflective garment and infrared reflective glove. At regular follow-up visits, training records recorded on the data memory are examined by the therapist by computer to determine whether re-evaluation of upper limb function is needed. If re-evaluation is needed, movement selections and exercise parameters will be set up; if it is not needed, the system software can automatically update the training program according to the training performance of the patient at the previous stage, and therapists can adjust corresponding training exercise parameters according to the actual situation of the patients. Then, the training program is stored in the data memory for the next rehabilitation training sessions.
Thirty-two movements achieving goals make up the core of the sports training of the system. Additionally, it includes 4 warm-up and relaxation exercises. We designed these upper limb motions (excluding hand) according to the Chinese Stroke Full Guideline. The rehab system structure and algorithm supports four sets: self-assisted, active feedback, table-assisted and active motion.
The rehab system guides patients to do exercises which cover 3 joints: shoulder, elbow and wrist. There were two sets involved in the 8 week exercise training.
Exercise Set: Two sets of exercises were used in the 8 weeks exercise training
9 Self-assisted exercises: the movement of the affected upper extremity is driven by the healthy upper extremity (Bobath method)
2 shoulder joint active exercises.
In the first 4 weeks, 9 self-assisted exercises and 4 warm-up and relaxation exercises were used. In the second 4 weeks, 2 shoulder joint active exercises, 9 self-assisted exercises, and 4 warm-up and relaxation exercises were used.
Exercise plan: Therapist chose 6-8 movements from the above exercise set every 2 weeks according to the subject’s condition. The therapist could determine range of motion and the number of repetitions for the chosen exercise.
The role of therapist during the system guided training: The therapist guided patients to understand and use the rehab system at the beginning of training, for example, how to complete calibration and how to follow guidance from the system. The therapists did not have any physical contact with the patients during the exercising process.
Exercise schedule: There were a total of 8 weeks of system therapy on the hemiplegic upper extremity (excluding hand), with 9 sessions per week, 20 minutes per session, for a total of 72 sessions.

ARM2:
Hemiplegic upper extremities (excluding hands) from treatment and control groups received neurodevelopmental treatment (NDT) based on conventional physical therapy. This consisted of one-on-one treatment provided by therapists focusing on exercise therapy including: active, passive, and assisted joint mobility, voluntary movement of shoulder, elbow, wrist and fingers in all directions, forearm rotation, relaxation exercises of upper limbs, limb positioning and maintaining activities, muscle stretch training, coordination training, task oriented training, and Activities of Daily Living training. Details of hemiplegic hand and lower extremity treatment of the treatment group and the control group were not specified for the trial and they were decided by therapists based on subject circumstances. There were a total of 8 weeks of conventional physical therapy on the hemiplegic limb: for the first 4 weeks, 5 minutes/session for the upper extremity, and 15 minutes/session for the hand and lower extremity; and for the second 4 weeks, 10 minutes/session for the upper extremity, and 10 minutes/session for the hand and lower extremity. There were 5 sessions per week, for a total of 40 sessions.

Comparator / control treatment
The control group received self-exercises by picture guidance. The picture exercise is a control devised to approximate the novel intervention and is according to the Chinese Stroke Full Guideline.
Exercise Set: 9 self-assisted exercises, 2 shoulder joint active exercises, 3 relaxation exercises and a muscle stretch exercise. In the first 4 weeks, 9 self-assisted exercises, 3 relaxation exercises and a muscle stretch exercise were used. In the second 4 weeks, all 15 exercises in the pictures were used.
Exercise plan: The therapist chose 6-8 movements from the above exercise set every 2 weeks according to the subject’s condition and asked them to self-exercise guided by the pictures.
The role of the therapist during self-exercise: The therapist explained the key points of movement in the pictures followed by verbal guidance and demonstration. Therapists did not have any physical contact with the patients during the self-exercise.
Exercise schedule: There were a total of 8 weeks of self-exercise guided by pictures on the hemiplegic upper limb (excluding hand), with 9 sessions per week, 20 minutes per session, for a total of 72 sessions.
