Background: Virtual reality (VR) training allows the creation of the most applicable practice environment incorporated into computer-generated multisensory imagery.
Objectives: The purpose of this study was to investigate the effects of a virtual training program based on a RAPAEL smart glove on the upper extremity function and quality of life of community-dwelling individuals with chronic hemiparetic stroke.
Methods: Thirty-six outpatients diagnosed as having a first stroke were selected to receive a therapeutic rehabilitation program at local rehabilitation units. Participants were allocated randomly into two groups: the non-immersive VR training (intervention) group and the recreational activity (control) group. The intervention group received non-immersive VR training using a RAPAEL smart glove for 30 minutes per session, 3 days a week for 8 weeks. The control group performed recreational activities for the same period and also participated in a conventional rehabilitation program for 30 minutes per session, 3 days a week for 8 weeks as an additional therapy. To analyze the effects of the non-immersive VR intervention on upper extremity function, four clinical measures, namely the box and block test (BBT), the Wolf motor function test (WMFT), the Jebsen-Taylor hand function test (JTT), and a grip strength test, were used in this study. For the secondary clinical outcome, the trail-making test (TMT) was used to determine any improvement in cognitive function.
Results: At week 8, upon completion of the non-immersive VR-training the intervention group demonstrated significantly greater WMFT scores (73.0±12.9 to 81.6±7.5), BBT scores (27.3±8.9 to 34.2±7.1), and grip strength (19.2±8.2 to 23.8±8.5) compared with WMFT scores (70.4±12.1 to 73.2±13.1), BBT scores (27.1±10.5 to 28.8±12.9), and grip strength (18.4±4.2 to 18.3±4.9) in the control group.
Conclusions: This study suggests that virtual upper extremity training using the RAPAEL smart glove has reasonable and beneficial effects on upper extremity and cognitive function for chronic hemiparetic stroke survivors.

Introduction: Rhizarthrosis, or osteoarthritis of the trapeziometacarpal joint, predominantly affects women over 50, with up to 30% experiencing some degree of arthritis in this joint. Traditional surgical approaches, such as trapeziectomy with ligament reconstruction, can result in some patients in persistent pain or limited functionality. TMC ball-in-socket arthroplasty, with a cup placed in the distal scaphoid, offers a promising alternative to traditional arthrodesis or resection-suspension arthroplasty.

Purpose Of The Study: Rhizarthrosis-osteoarthritis of the thumb carpometacarpal (CMC) joint is usually a primary idiopathic disease. Total joint arthroplasty (TJA) is one of the surgical treatment options for symptomatic advanced thumb CMC arthritis. This retrospective study aims to evaluate the mid-term functional and radiological results of TJA with the minimum follow-up period of 3 years after the surgery.

Hand(s)-tapping tasks have been extensively studied in order to characterize the features of sensorimotor synchronization (SMS). These tasks frequently require participants to synchronize their tapping pace to an external, metronome-like sound. The impact of ageing on SMS abilities remains mainly unexplored.

Objective: Superior vena cava syndrome (SVC) is a debilitating disease, and surgical reconstruction has been described with some of the best results using spiral great saphenous vein (SGSV) grafts. SGSV grafts can be difficult to construct, and a long segment of saphenous vein is needed. Femoral vein has been an excellent conduit for infected aortic and peripheral reconstructions in our hands, and we sought to review outcomes using this conduit for SVC reconstruction.

Background: Core curricula do not include courses on how to find employment after hand fellowships. Little data exists in literature regarding job selection in hand surgery. This study's purpose was to provide information to future hand surgeons on ways of finding a job that meets their expectations and to elucidate factors that should be considered before deciding on a hand practice.
