Using NetMeeting for remote configuration of the Otto Bock C-Leg: technical considerations.

Area of Science:

• Biomedical Engineering
• Rehabilitation Technology
• Digital Health

Background:

• Telehealth offers potential for remote support of advanced prosthetic devices.
• Computer-controlled prosthetics require specialized technical and clinical configuration.
• Remote adjustments can improve accessibility and patient outcomes.

Purpose of the Study:

• To evaluate the feasibility of using internet-based video conferencing for remote configuration of the Otto Bock C-Leg prosthetic.
• To assess the impact of different internet connection speeds on the remote configuration process.

Main Methods:

• A pilot study utilized Microsoft NetMeeting for remote C-Leg configuration between two computers.
• Tests were conducted over various local area network (LAN) speeds (56 Kbps, DSL/Cable, 10 Mbps) and a 28 Kbps modem connection.
• Remote configuration involved Application Sharing, Live Video, and Live Audio functionalities.

Main Results:

• Successful remote configuration of the C-Leg was achieved at higher internet speeds (56 Kbps and above).
• Lower internet speeds (28 Kbps) limited the real-time update of critical configuration data, such as peak toe loads and knee angles.
• The study demonstrated the potential of NetMeeting for cost-effective remote prosthetic adjustments.

Conclusions:

• Internet-based video conferencing is a viable tool for remote C-Leg configuration.
• Adequate internet data transfer speed is essential for the successful implementation of telehealth for prosthetic support.
• This technology can enhance accessibility and reduce costs associated with prosthetic device management.
