The Impact of Real-Time Biofeedback on Partial Weightbearing Training: A Comparative Study.
Leonard Lisitano, Zarek Hezrrai DaSilva, Nicholas Koch and 5 others
PMID 40041539WHAT IT FOUND
Adding real-time audio-visual biofeedback to standard training helped 88% of healthy adults meet the partial weightbearing compliance criterion during walking, compared with 19% using standard training alone.
Key findings
01Adding real-time audio-visual biofeedback to the same standard training was associated with 88% meeting the compliance criterion, compared with 19% in the standard training group.
02The biofeedback group required 9 minutes 00 seconds of training on average, while the standard care group required 12 minutes 49 seconds on average.
03In the second assessment, all biofeedback participants met the compliance criterion, while 59% of standard care participants met it.

What it does not show
The participants were healthy adults aged 18 to 47 who could already walk unassisted, so the results may not apply to patients with fractures, pain, surgery, older age, obesity or other illness. The study measured training compliance and load during a mobility course, not bone healing, implant failure, pain, function or recovery time. The load target was a fixed 20 kg rather than a percentage of body weight, so the relative effort varied between participants. The satisfaction differences were not statistically significant, so the study did not show that participants preferred the biofeedback method over standard training.
Declared interests
The authors report no conflicts of interest.
The easy way to misread this
Do not read the 88% versus 19% compliance result as proof that biofeedback improves healing or prevents complications in patients. It tested healthy adults learning a weightbearing task, not people with fractures or surgery.
