Grasp Analysis in the Home Environment as a Measure of Hand Function After Cervical Spinal Cord Injury.

The final analysed number of participants is not stated in the numbered text. One participant did not complete the study, and two were removed because too few hand-object interactions were collected. All grasp annotations were done by one person, although the annotations were repeated and a second person checked a subset of frames. Knowing that a camera was recording may have changed how participants performed tasks. Most participants had milder impairment, mostly AIS D, so the results may not apply to people with severe hand impairment. The grasp categories were developed for people without impairment, so some SCI-specific hand patterns may have been missed. Only stable portions of grasps were analysed, so transitions and unusual grasp patterns were not included.

The authors declared no potential conflicts of interest. Funding came from the Craig H. Neilsen Foundation and the Ontario Early Researcher Award program.

Do not conclude that this home grasp method has been tested to improve hand function or that it replaces clinic assessment. The study found associations between grasp use and clinical scores, not treatment effects.
