A virtual rehabilitation system based on EEG-EMG feedback control

In recent years, many different technologies on virtual rehabilitation have been produced and used in research. However, existing studies are limited because most of them focus on the balancing ability of the elderly or studied stroke patients with same systems. Thus, it is necessary to investigate the effects of a new virtual rehabilitation system in patients with Anterior Cruciate Ligament (ACL) Reconstruction. The purpose of this study was to investigate the effects of a virtual rehabilitation system using a MarVAJEDÂ® system which provides visual and auditory stimulus aimed at educating and controlling the joint proprioception, range of motion, pain intensity, and knee swelling in individuals with an ACL injury. A total of fifteen patients with ACL reconstruction participated in this study. In addition to conventional physiotherapy, a virtual rehabilitation treatment was applied with visual and auditory stimulus for a total of eight weeks, three sessions per week. There were statistically significant improvements in measures of proprioception, range of motion, pain intensity, and knee swelling between preâ€“ and post â€“ treatment (p<0.05). We concluded that this new VR system known as MarVAJED effectively treat ACL patients by improving proprioception, range of motion, and by decreasing pain intensity, and knee swelling.

Abstract Background After stroke, sustained hand rehabilitation training is required for continuous improvement and maintenance of distal function. Methods In this paper, we present a system designed and implemented in our lab: the Home based Virtual Rehabilitation System (HoVRS). Fifteen subjects with chronic stroke were recruited to test the feasibility of the system as well as to refine the design and training protocol to prepare for a future efficacy study. HoVRS was placed in subjects’ homes, and subjects were asked to use the system at least 15 min every weekday for 3 months (12 weeks) with limited technical support and remote clinical monitoring. Results All subjects completed the study without any adverse events. Subjects on average spent 13.5 h using the system. Clinical and kinematic data were collected pre and post study in the subject’s home. Subjects demonstrated a mean increase of 5.2 (SEM = 0.69) on the Upper Extremity Fugl-Meyer Assessment (UEFMA). They also demonstrated improvements in six measurements of hand kinematics. In addition, a combination of these kinematic measures was able to predict a substantial portion of the variability in the subjects’ UEFMA score. Conclusion Persons with chronic stroke were able to use the system safely and productively with minimal supervision resulting in measurable improvements in upper extremity function.
