The Use of 3D Printing Technology in Rehabilitation for Adults Living With Neurological Conditions: Scoping Review.

The included studies were very small and varied in design and intervention, so the review cannot say how well these devices work for most patients. The search was limited to English publications, so relevant studies in other languages may have been missed. The search did not use occupational therapy, audiology, or nursing terms, so it may have narrowed the findings. All included studies were from high- or upper-middle-income countries, so this says little about low-resource settings. Printer type, materials, and fabrication processes were inconsistently reported, so clinicians cannot compare methods or replicate devices from this review.

No external funding was received, the authors did not receive financial support, and no conflicts of interest were declared.

Do not read this as evidence that 3D-printed devices improve motor recovery. It is a scoping review of small, heterogeneous studies, and the review could not draw generalizable conclusions about effectiveness.
