Table 3 Survey comments on Archercise exercise protocol performed with biofeedback

General positive

Everything worked well

Much easier

Biofeedback helped

Biofeedback made the task easier and my foot muscles seemed to improve

Everything worked well

Simply, the visualisation works very well

The feedback all worked to get the exercise correctly

The biofeedback was fantastic and was very helpful in the tasks

Good to get feedback, hard to reach some of the highest markers, helps to recreate the expected patterns

Specific biofeedback GUI

I felt that the graphs were a huge help for me to perform the tasks as they were described to me.

Seeing my progress on the screen was good

Seeing the monitor gave good feedback on whether I’m doing the task correctly or not

The feedback helped to understand the concept of slowly lifting up and lowering down, and having the feedback helped with endurance and know that ‘i’m doing the right thing.

Negative comments

Concentrating on the new task (lowering the arch) and looking at the screen was difficult.

Fatigue affected the latter results.

Bladder

Bladder provided useful tactile feedback

Feeling the bladder under the arch helped enormously with arch awareness.

The pressure under the arch was very helpful and informative

Foot locators

Works well to see how your foot position changes are shown on the screen, to feedback if you are doing it correctly, especially with the speed test.

…. assisted specially with the little toe

Visual display

It was easier to understand what I was supposed to do with visual feedback.

The biofeedback made a huge difference in how I perceived that I performed the tasks, especially the arch relaxing task.

The screen really helps to complete the tasks.

The screen was a good stimulus to do the exercises properly

Pressure waves & guidance line of best fit (helped).

The guide and feedback when doing lifting up and lowering down helped with controlling the movement.

Help in most tasks but not helpful for me with the eccentric task^a.
