• Aim
• Design and develop telerehabilitation (TR) system
  with customized consultation categories.
• Evaluate novel bandwidth adaptation algorithm to
  ensure system functionality in narrow-bandwidth
  environments.
• Relevance
• TR systems that are usable under low-bandwidth
  network environments are rare.

3
Method

• Method for bandwidth adaptation was introduced.
• Different consultation categories were identified
  based on TR session requirements.
• Each category was formed with varying parameter
  settings frame rate, compression quality, color
  information, cropping features, and spatial data
  extraction.
• System was evaluated for minimum bandwidth
  required to be used successfully in TR session.

4
Results

• System performed effectively in each consultation
  category while the rehabilitation exercises were
  being performed.
• Proposed algorithm adapted content quality and
  effectively utilized the network under
  constrained conditions.
• Results of survey on video quality of system
  under low-bandwidth conditions were encouraging
  for large-scale deployment of the application.

5
Conclusion

• Experimental results and ground survey responses
  suggest that using the developed system in
  bandwidth-limited environments, such as rural
  areas in developing countries, may allow
  successful TR sessions with specialists in the
  city or even other countries.
