Shoulder Abduction & Adduction AROM & Stability

Updated: Aug 20, 2019

In this mini v/blog post we'll examine a clinical application of #mocap. EuMotus BodyWatch is designed for #physicaltherapy clinicians.

Clinicians who use EuMotus BodyWatch use it for two main clinical reasons.

The first is to have an objective record, that automatically records objective data on the patient's movement. So if a patient comes in with a shoulder issue, the clinician can choose to record a patient baseline at the first visit. The clinician can choose to record and focus on a baseline of one or more of the following example metrics:

  • shoulder abduction & adduction active range of motion (AROM),

  • movement instability such as shoulder protraction during all or certain parts of shoulder movement, and/or

  • a/symmetry analysis - the clinician can choose to compare the affected relative to the contralateral shoulder.

Second, clinicians can also elect to use EuMotus clinical mocap to help better engage, and educate the patient. When shown visual graphics or videos of the patient movement, most patients, from teenagers through weekend warriors, and geriatrics get excited!

Make your patient's physical therapy visit even more fun!

"Wow, that's me! Look at my red skeleton and me doing the flossing dance.
But wait!! Why is my ___________ red?"

Getting your patient to their "But wait!" moment can help in improving their understanding of the movement issue at hand, as well as improving their buy-in and commitment to going through the full process of physical therapy.

Clinical motion analysis can be a small, but potent part of getting your patient to their "But wait!" moment.

Awesome! Now that we've established a couple of clinical reasons to use motion analysis in your clinic, below is an example application of EuMotus BodyWatch.

In the video below, we record Lynn performing shoulder abduction & adduction in the transverse (horizontal) plane. Our fully markerless single 3D sensor and computer vision algorithms automatically detect that Lynn is a human performing a shoulder abduction exercise!

No complex setup required! No markers!

As soon as the 15 second exercise is done, we see the summary screen, where maximum shoulder abduction & adduction values are automatically displayed, relative to normative data for a healthy, active adult. No post-processing of data or number crunching is required from the user. The traffic light summary - red light, yellow, green light - hints of areas of more or less concern.

If the clinician chooses to dig deeper, they can head to the graph & video analysis mode. The PT can plot selected metrics of interest. In the case of Lynn's shoulder abduction & adduction exercise in the transverse plane, we plot the according shoulder AROM, as well as the movement instability of shoulder protraction (shoulder roll).

The clinician can now observe if and when the particular movement instability occurs.

Watch the video below the shoulder transverse abduction AROM video to see how EuMotus BodyWatch works for yourself!

Below we have another video on shoulder coronal plane abduction & adduction. We measure shoulder frontal plane active range of motion (AROM).

Do you have questions or ideas on the application of EuMotus markerless mocap in your PT clinic? We'd love to speak with you! Contact us at hello / at / eumotus / com.

Thank you for watching!
