Using this online EMG feedback, subjects were trained to fully relax their resting limbs even when movements were performed with the other body side (figure 2).
Without performance feedback, subjects rushed to intercept a moving target in an animate context, whereas they dragged in an inanimate context.
2) Implicit feedback: Subjects will undergo a dynamic visual feedback intervention.
Following feedback subjects were then presented with an outcome screen (750 ms).
When performing the task with images instead of visual feedback, subjects received feedback (mean, SD of force) after a series of trials.
2. Mirror feedback: Subjects were instructed to perform the routine in front of a mirror and use the feedback from the reflection of their body on the mirror.
Following modification of the PROM, based on patient feedback, subjects reported that the tool was fully inclusive and easy to comprehend.
This finding suggests that during visual feedback subjects were paying attention to their performance on the computer screen and possibly physiologically loading their anaerobic system to a greater level, but they did not experience a higher perceived fatigue.
This solicited feedback from subject matter and clinical experts during development was an unusual but valuable step in shaping this decision aid.
By soliciting feedback from subject matter experts, family leaders, and the lay public, we improved the likelihood that the questionnaire items will be understood and interpreted as intended.
