Health professional (n=4) interviews:
+“I think you couldn’t make this much easier..”
-“My bug bear a bit; technology coming into our
job is meant to save us time, but often it doesn’t.”
-“If they had an activity monitor…”

Chain Linked Electro Goniometer (CLEG):
-Full freedom of movement, cheap, robust
-RMS error vs pre-set angles 1.1°
-relative non linearity 0.37%
-does not influence walking ROM
-Validity and reliability…..LOA
-activity recognition…
