Assessing Physical Therapists' Expectations and Experiences With an Automated Rehabilitation System Using Technology Acceptance Model: Multiple Methods Pilot Study.
Cynthia Williams, Lindsay Toth, Raine Osborne and 2 others
PMID 40773738WHAT IT FOUND
Five physical therapists' perceived usefulness and ease of use of a new knee rehabilitation wearable significantly decreased after a month of use.
They cited calibration issues and setup time as barriers, suggesting the prototype needs substantial refinement before clinical adoption.
Key findings
01Perceived usefulness and ease of use scores significantly decreased after therapists used the device.
02Therapists reported technical challenges, specifically calibration issues and setup time, as major barriers to use.
03The expected frequency of using the device with patients significantly decreased after exposure to the system.

What it does not show
The sample size was very small (5 physical therapists), limiting generalizability. The study was conducted during the COVID-19 pandemic, which may have affected patient availability and in-person care dynamics. The participants were recruited from a single rehabilitation organization in one geographic region. The study used a prototype system, so findings may not apply to commercially available devices.
Declared interests
None declared.
The easy way to misread this
Do not conclude that wearable sensor technology is ineffective for knee rehabilitation. This pilot tested a specific prototype with usability issues in a very small sample; the negative findings reflect the current state of this specific device's design and reliability, not the potential of the technology class as a whole.
