PMID 30392855WHAT IT FOUND
Clinicians rarely use surface EMG in neurorehabilitation, citing lack of time, training, and evidence.
They want simple, waterproof, low-cost systems with intuitive apps that show patients early progress. Current tools fail to meet these needs, preventing routine clinical uptake.
Key findings
01Most clinicians rely on low-tech assessment and treatment methods because sEMG systems are too complex, expensive, and lack training support.
02Clinicians see value in sEMG for showing patients early, objective progress and providing biofeedback, but require systems that are simple, waterproof, and affordable.
03Barriers to sEMG adoption include institutional budget constraints, lack of robust evidence linking signals to functional outcomes, and poor usability of current devices.

What it does not show
The study used convenience sampling from a single metropolitan region (Seattle), so findings may not represent clinicians in other geographic or institutional contexts. Participants had limited prior experience with sEMG, which may have influenced their perceptions of usability and barriers. The demonstrations were brief 'show and tell' sessions, so clinicians could not assess real-time setup or implementation challenges in their own clinics. Qualitative methods cannot determine the frequency of these views across the wider profession or measure clinical outcomes.
Declared interests
The study was supported by the National Institutes of Health (N.I.H., Extramural). The text does not report any other conflicts of interest or commercial funding.
The easy way to misread this
Do not interpret this study as evidence that sEMG improves patient outcomes. It reports clinician perceptions and barriers to adoption, not clinical efficacy. The lack of uptake is attributed to usability and resource issues, not necessarily a lack of clinical value, but no data here proves sEMG works better than current low-tech methods.
