Shoulder Kinematic motion analysis

[Jason Yu]

Dear experts,

would you please suggest any parameter to quantify the upper limb performance in terms of smoothness/effectiveness/performance.
Thanks.

Dear Dr. Jason Yu,

Perhaps the paper below may have some useful information for your research:

"Reliability of the Performance of Upper Limb assessment in Duchenne muscular dystrophy"

"Abstract
The Performance of Upper Limb was specifically designed to assess upper limb function in Duchenne muscular dystrophy. The aim of this study was to assess (1) a cohort of typically developing children from the age of 3 years onwards in order to identify the age when the activities assessed in the individual items are consistently achieved, and (2) a cohort of 322 Duchenne children and young adults to establish the range of findings at different ages. We collected normative data for the scale validation on 277 typically developing subjects from 3 to 25 years old. A full score was consistently achieved by the age of 5 years."
