Virtual reality-based orthopedic telerehabilitation.

Rehabilitation interventions in remote areas are problematic because of distance and available resources. Orthopedic impairments acquired by individuals in remote areas can then lead to permanent disabilities/loss of function because of lack of appropriate rehabilitation. A system being developed by Rutgers and Stanford Universities provides therapy at the patient's home, with remote monitoring and periodic re-assessment. This telerehabilitation system uses virtual reality and haptic interfaces, and a pair of networked PCs. It is intended for rehabilitation of patients with hand, elbow, knee and ankle impairments. Data from the first patient treated with the telerehabilitation system is encouraging.

PC-based telerehabilitation system with force feedback.

A PC-based orthopedic rehabilitation system was developed for use at home, while allowing for remote monitoring from the clinic. The home rehabilitation station has a Pentium II PC with graphics accelerator, Polhemus tracker, and a novel Multipurpose Haptic Control Interface with its own Pentium board. This interface is used to sample patient's hand positions and to provide resistive forces using the Rutgers Master II (RMII) glove. A library of virtual rehabilitation routines was developed using WorldToolKit software. At the present time, it consists of two physical therapy exercises (DigiKey and Ball) and two functional rehabilitation exercises (Peg Board test and Ball game). All VR exercises allow automatic and transparent patient data collection into an Oracle database. A remote Pentium II PC is connected with the home-based PC over the Internet and an additional video-conferencing connection. The remote computer running Oracle server is used to maintain the patient database, monitor progress and change exercise level of difficulty. This allows for timely patient progress monitoring and repeat evaluations over time from the Clinic. The system will soon start clinical trails at Stanford Medical School, with progress being monitored remotely from Rutgers University. Other rehabilitation haptic interfaces under development include devices for elbow, and knee rehabilitation connected to the Multipurpose Haptic Control Interface.

Reconstruction of individual digits.

The development of microvascular techniques has encouraged the hand surgeon to re-examine the principles of reconstructive surgery. The transfer of vascularized composite tissues, if technically well done, can obviate the need for time-consuming staged procedures. However, success in microvascular reconstruction comes not in the knowledge of anastomotic techniques but in the understanding of the physiology of wound healing, the mechanics of hand function, and the principles and goals of hand reconstruction.

Case report: false aneurysm of the hand secondary to digital amputation.

A false aneurysm in an amputation stump of the second metacarpal produced a pulsatile mass and throbbing pain. Operative findings disclosed a false aneurysm arising from the digital artery on the radial side of the middle finger, with entrapment of the nerve to the ulnar side of the index digit within the aneurysmal sac. Excision of the aneurysm, relocation of the traumatic neuromas, and amputation of the index ray relieved the symptoms.
