Factors associated with upper extremity use after stroke: a scoping review of accelerometry studies.

The review included only cross-sectional associations, so it cannot determine if these factors cause changes in arm use over time. Data extraction was performed by a single author, which increases the risk of errors or bias. The analysis focused on univariate associations, meaning some factors might appear significant only because they are correlated with upper extremity impairment, not because they independently influence use. There was wide variability in how accelerometry metrics were calculated across studies, making direct comparison difficult. Few studies investigated environmental or participation factors, leaving these areas under-explored.

The work was supported by the Fonds de Recherche du Québec - Santé. No other conflicts of interest are explicitly detailed in the provided text.

Do not assume that a patient's clinical score in the therapy gym reflects their actual arm use at home. The review shows that capacity and use are associated but not identical, and many patients with good capacity still underutilize their arm. Use wearable sensors or detailed activity logs to verify if capacity translates into daily use.
