Half Arm Raise. Level 1 Example

Background:
This stroke survivor had not used his arm in any rehabilitation form for 6 years. This exercise was to demonstrate that he could his start to work on  some isolation of his left arm. Here in this example, there is some compensation of the trunk, which was eliminated in later levels. As a starting point this initial movement in his right arm was motivating for him.

Note the controller is inverted, with a inverted manfrotto stand. The arm has  5 inches to travel to connect the controller.

The concentration required to employ motor skills to move his right arm, resulted in some minor cognitive fatigue.
