Shoulder pain and cycle to cycle kinematic spatial variability during recovery phase in manual wheelchair users: a pilot investigation
For wheelchair users the shoulder joint is often crucial for controlling their chair. There is growing evidence that kinematic variability is linked to wheelchair users shoulder pain, although this has never been used as a marker for wheelchair propulsion.
It was seen that there was no significant difference in mean power whether users had shoulder pain or not, nor did pain effect range of motion during propulsion. Users with a pre-existing shoulder condition did however show greater kinematic variability during the recovery phase. Moving at a higher speed gave greater ROM and it is believed that this accounts for no changes in kinematic variability when recovering from these faster runs.
Further study of the presence of these movement variances can be used to better track the treatment of, or to prevent future, shoulder injuries. > From: Jayaraman et al., PLoS One 9 (2014). Distributed under the terms of the Creative Commons Attribution License.
