A comparative study of the efficacy and functionality of 10 commercially available wrist-hand orthoses in healthy females during activities of daily living.

The study used only healthy participants, so the findings may not apply to patients with pain, stiffness, or muscle weakness who might interact with the orthoses differently. The orthoses were fitted by an expert team to ensure optimal fit; in real life, patients often self-fit these devices, which may result in poorer performance and comfort. The sample size was small (n=10), limiting the generalisability of the comparisons between specific orthoses. Compensatory movements at the shoulder and elbow were not measured, so the true functional cost of wearing the orthoses may be underestimated.

The study was funded by Versus Arthritis UK. The authors declared that the funding body had no role in the study design, data collection, analysis, or manuscript preparation.

Do not assume that a prefabricated orthosis will immobilise the wrist as intended. The study showed that none of the ten devices consistently blocked flexion or radial deviation during daily tasks, and all slowed down task performance. Prescribing them as a simple solution for wrist instability may lead to patient frustration and reduced adherence due to the functional delays.
