Abstract Background: Task-specific training has been proven to be effective in promoting recovery of the hemiparetic upper extremities after a stroke. This study was to develop a new and innovative task-specific VR (TS-VR) program using a Leap Motion Controller VR device and the Unity3D program for distal hand function training, and to investigate whether a two-week program of TS-VR training would promote recovery of the hemiparetic upper extremity in patients with chronic stroke.Methods: We designed the TS-VR program based on seven general hand function tasks used in the activities of daily living that require upper limb movement, such as pushing open a door and pouring water. Then, we examined the content validity of the TS-VR according to the views of an expert panel and through field testing on patients with stroke. The final version of the TS-VR was tested on 20 patients suffering from chronic stroke with upper extremity hemiparesis over 2 weeks, 5 sessions per week, 30 minutes per session. Outcomes were assessed using the Fugl-Meyer Assessment-Upper Extremity score (FMA-UE), the Wolf Motor Function Test (WMFT), and the Motor Activity Log (MAL). Data were collected at the first session (week 0), last session (week 2), and follow-up session (week 5). Patients’ arm impairments were stratified into lower- and higher-functioning groups according to the Functional Test for the Hemiplegic Upper Extremity (FTHUE).Results: Significant improvements in upper extremity functions were found after TS-VR training in FMA-UE Total score (χ2=34.219, p=0.000), FMA-UL subscore (χ2=31.2, p=0.000), FMA-Hand subscore (χ2=22.6, p=0.000), and WFMT score (χ2=27.8, p=0.000) among the three time occasions, but no significant effect on grip strength was found. Moreover, the higher-functioning group (levels 5-7 in FTHUE) benefited more from the TS-VR, as indicated in outcome measures of FMA-UL, FMA-Hand, FMA-UE Total, and WMFT respectively, as well as amount of use score in MAL, but this was not the case for those in the lower-functioning group (levels 1-4 in FTHUE).Conclusions: Our findings suggest that our new TS-VR training system was useful for upper extremity recovery in patients with chronic stroke. It has potential to be applied in clinical settings in future.

Abstract Permanent impairment cannot be assessed until the patient is at maximum medical improvement (MMI), but the proper time to test following carpal tunnel release often is not clear. The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) states: “Factors affecting nerve recovery in compression lesions include nerve fiber pathology, level of injury, duration of injury, and status of end organs,” but age is not prognostic. The AMA Guides clarifies: “High axonotmesis lesions may take 1 to 2 years for maximum recovery, whereas even lesions at the wrist may take 6 to 9 months for maximal recovery of nerve function.” The authors review 3 studies that followed patients’ long-term recovery of hand function after open carpal tunnel release surgery and found that estimates of MMI ranged from 25 weeks to 24 months (for “significant improvement”) to 18 to 24 months. The authors suggest that if the early results of surgery suggest a patient's improvement in the activities of daily living (ADL) and an examination shows few or no symptoms, the result can be assessed early. If major symptoms and ADL problems persist, the examiner should wait at least 6 to 12 months, until symptoms appear to stop improving. A patient with carpal tunnel syndrome who declines a release can be rated for impairment, and, as appropriate, the physician may wish to make a written note of this in the medical evaluation report.
