- OBJECTIVE: To investigate whether training in a virtual environment with a haptic device will improve motor function in the left hemiparetic arm of a stroke subject. DESIGN: Single case, A-B-A design. SETTING: University hospital research laboratory. PARTICIPANT: A man in his late fifties (right handed), with a right-hemisphere lesion that caused a deficit in the left upper extremity. INTERVENTION: The subject trained with a 3-dimensional computer game during a 4-week period that consisted of twelve 90-minute sessions. MAIN OUTCOME MEASURES: Three tests (Purdue pegboard test, dynamometer hand-grip strength, upper-extremity test) and a subjective interview were used to evaluate motor performance. RESULTS: Improvements were found in fine manual dexterity, grip force, and motor control of the affected upper extremity. The subject reported that there was a change in his day-to-day use of the upper extremity and that he was able to use it in activities that were previously impossible for him. CONCLUSIONS: Training with virtual reality and haptics can promote motor rehabilitation.

- Virtual reality (VR) technology is altering the health care environment and is changing the options that are available to therapists. This study describes how a haptic device was used as a cinematic assessment utility. Three chronic stroke inpatients at Sahlgrenska University Hospital with left hemisphere damage were assessed. The patients were administered by the box and block manual dexterity test. For comparisons, a reference group was added to the study. Several parameters, including time, speed, and movement of the right upper extremity, were extracted and evaluated. The results indicate that the system shows potential as an assessment device. The feasibility study setup is working well, as is the assessment method. Further research, testing, refinement of the exercises, and use of VR and haptics within neurological rehabilitation are suggested.

- A 3D-computer game was used as a training utility to promote motor relearning on a telemedicine platform in a laboratory setting. The subject suffered from a left arm paresis. He was evaluated before and after treatment with a specific hand function task, a standardized grip force measure test and an upper extremity task. Grip force, endurance and the movement pattern of the upper extremity improved after the treatment. The telemedicine platform allows the professional to record and evaluate progress. The findings implicate that training with Virtual Reality and Haptics can promote motor rehabilitation

- The objective of this pilot study is to identify the level of difficulty in which subjects with left hemisphere damage in the acute phase after stroke can start practicing in a virtual environment. Second, to test an application of Virtual Reality technology to existing occupational treatment methods in stroke rehabilitation and develop a platform for home rehabilitation controlled telemedically. The findings indicate that the system shows potential as an assessment and training device. The feasibility study setup is working well likewise the assessment method. Developing and increasing the complexity of the tasks must be based on the patient individual neurology, and that the cinematic motion patterns of the patient's are the basis for exercise design.
