Assessment of Motor Compensation Patterns in Stroke Rehabilitation Exercises

Assessments are totally fucking worthless, we need EXACT STROKE PROTOCOLS that provide 100% recovery. WHEN THE HELL WILL YOU GET THERE? When you are the 1 in 4 per WHO that has a stroke will you be satisfied with this crapola and not getting recovered?

Abstract 

The increasing demand concerning stroke rehabilitation and in-home exercise promotion requires objective methods to assess patients’ quality of movement, allowing progress tracking and promoting consensus among treatment regimens. In this work, we propose a method to detect diverse compensation patterns during exercise performance with 2D pose data to automate rehabilitation programs monitorization in any device with a 2D camera, such as tablets, smartphones, or robotic assistants. 1 Introduction With the escalating demands towards stroke rehabilitation and the increase of in-home exercise recommendations [2], the need for new means to evaluate patients’ motor performance has risen [4, 7]. In conventional assessment tests, therapists assess movement quality based on observation, thus being highly subjective [4]; with the degree of experience implying distinct treatment approaches [7]. Quantitative and objective methods allow patients’ progress tracking, impaired movements’ understanding, and formulation of standard therapy regimens [4, 6]. Patients’ physically impaired often exhibit compensation behaviors to accomplish a task. Motor compensation is the presence of new movement patterns derived from the adaptation or substitution of old ones, which might help patients’ execute a task [5]. New patterns can include the use and activation of additional or new body joints and muscles. Most typical compensation behaviors are trunk displacements, rotation, and shoulder elevation. These functional strategies are commonly observed in reaching and are highly related to severe impairment levels [5]. Early on the recovery process, the use of compensation strategies promotes patients’ upper limb participation in task performance. However, their persistence may obstruct real motor function recovery and must be reduced during therapy through appropriate exercise instructions [5]. In this work, we present a method to assess quantitatively motor compensation from video frames during upper limb exercise performance. We have created a label set (Table 2) for each video frame of the dataset regarding the observed compensation patterns. We then explore two methods to assess these patterns based on 2D pose data enabling this kind of analysis with widely available RGB cameras.
