Comparing a Sensor for Movement Assessment With Traditional Clinical Assessment Methods in Patients After Knee Surgery.
Comparing a Sensor for Movement Assessment With Traditional Clinical Assessment Methods in Patients After Knee Surgery.
Eight parameters measurable by the sensor "Orthelligent Pro" are compared with traditional measurements based on a goniometer or video taping. The aim is to inform potential users about the distribution of the differences they have to expect when moving from traditional measurement methods to the new sensor.
Patients will perform eight corresponding movement exercises at a single study visit.
In patients suffering from musculo-skeletal disorders, the restoration of full functioning is an important goal of many interventions. Assessment of functioning is often based on corresponding tests. If functioning is related to specific movement patterns, accelerometers and similar sensors are promising to allow a simple and objective assessment, and may replace traditional assessment methods, e.g. based on measurements with the goniometer. Corresponding products tend to enter the market and face clinicians and patients with the question, to which degree they are reliable and comparable with the traditional assessment methods.
Recently, a sensor named "Orthelligent Pro" has been released by the medical device company OPED and is today commercially available. The sensor - to be attached to the knee of a subject - offers the opportunity to assess several parameters related to movement patterns in the lower extremities that are of relevance in the rehabilitation process of orthopedic patients.
The aim of the current project is to inform potential users of this sensor about the difference they have to expect when compared to traditional assessment techniques of the same parameters and about the reproducibility of the measurements both based on the sensor and based on traditional assessments.
Patients of a single clinic will be offered participation. The patients will perform the eight exercises at a single study visit arranged as an addition to a routine follow up visit.
