Also the therapist pushed perfectionism that Peter Levine writes about in Movement elitism.
At least you can tell your therapist they don't know what they are doing, with robots it is kinda hard to get through to them. This example of voice activated elevator in Scotland is instructive.
Automatic Detection of Compensation during Robotic Stroke Rehabilitation Therapy
Abstract:
Robotic
stroke rehabilitation therapy can greatly increase the efficiency of
therapy delivery. However, when left unsupervised, users often
compensate for limitations in affected muscles and joints by recruiting
unaffected muscles and joints, leading to undesirable rehabilitation
outcomes. This study aims to develop a computer vision system that
augments robotic stroke rehabilitation therapy by automatically
detecting such compensatory motions. Nine stroke survivors and ten
healthy adults participated in this study. All participants completed
scripted motions using a table-top rehabilitation robot. The healthy
participants also simulated three types of compensatory motions. The 3-D
trajectories of upper body joint positions tracked over time were used
for multiclass classification of postures. A Support Vector Machine
(SVM) classifier detected lean-forward compensation from healthy
participants with excellent accuracy (AUC=0.98, F1=0.82), followed by
trunk-rotation compensation (AUC=0.77, F1=0.57). Shoulder-elevation
compensation was not well detected (AUC=0.66, F1=0.07). A Recurrent
Neural Network classifier (RNN), which encodes the temporal dependency
of video frames, obtained similar results. In contrast, F1- scores in
stroke survivors were low for all three compensations while using RNN:
lean-forward compensation (AUC =0.77, F1=0.17), trunk-rotation
compensation (AUC =0.81, F1=0.27), shoulder-elevation compensation (AUC
=0.27, F1=0.07). The result was similar while using SVM. To improve
detection accuracy for stroke survivors, future work should focus on
predefining the range of motion, direct camera placement, delivering
exercise intensity tantamount to that of real stroke therapies,
adjusting seat height, and recording full therapy sessions.
