Orthelligent®: ein Rehab/Pre-hab Gerät

Last week the company Orthelligent® visited PHYSIO RESTART. I invited them because I was looking for something which supports and optimizes my work as a physiotherapist in clinical practice. For that matter it needs to be evidence-based, high quality, time-saving, easy to set up and use and motivating for the patient.

After an introduction and try out by myself, I decided to order a 3-months trial version to convince mysel of its benefit.

"Orthelligent Knee Rehab is a digital rehabilitation program including a motion sensor and an associated app for the lower extremities.“ ( )

The sensor is wrapped around your knee and measures your joint alignment and muscle performance during different functional tasks. Via an App on the iPad we can have immediate feedback about your knee range of motion, coordination, stability and balance.

The exercises on the App are standardized tests I use in clinical settings to evaluate your performance after an injury but also as a prevention to detect any asymmetry and deficit. We are able to compare your injured extremity’s function to your healthy one as well as set your results in relation to reference scores of a large population group.

Why is it good to use?

Because the sensor and tests…

  • ensure a speedy recovery and safe return to activity and competition

  • evaluate range of motion, coordination, and strength / speed while providing instant feedback on the app

  • give reliable conclusions concerning the healing process which is ideal for function-based after-care following an injury

  • track the recovery progress and effectiveness of therapy


Are there goals to reach?

Yes! Orthelligent has a large reference group consisting of scores from varies ages and weights of healthy and injured persons. These data give us the opportunity to compare your results and evaluate your progression in different rehab phases.

For example: In phase 1 after an ACL surgery you should reach the full range of motion in your knee, because at least 0° knee extension is important for a normal gait, 110° flexion for riding a bike. In the last stage of rehab, studies recommend that you should have at least 85-90% performance of the healthy leg.

For whom is it convenient?

  • for persons who undergo a conservative rehabilitation programme to guide their progression and return to sport / competition after an injury on the lower extremity

  • for persons after a surgery to guide their progression and return to sport / competition after an injury on the lower extremity

  • for healthy persons who would like to know about their extremities' performance regarding range of motion, stability and coordination


* Injuries include any muscle, ligament, tendon strain/rupture or contusion, joint instability, degenerative joint conditions, muscle imbalances and many more!

Note: The team of Orthelligent is working constantly on improvement, safety and new developments. In future we may be able to use it also for other parts in the body?

I think that this device will be a new guidance for my clinical decision making process! (Anneke Klostermann, CEO PHYSIO RESTART)
