AbstractBackground & Aim
Distal radius fracture is a sentinel event associated with postural instability and 2-4 times increased risk of subsequent hip fractures. Preventing imminent risk of fractures is therefore crucial. The primary objective is to apply low-magnitude high-frequency vibration (LMHFV) therapy, a non-invasive biophysical intervention, to improve postural stability and prevent falls in distal radius fracture elderly patients.

Methods
An investigator-blinded randomized controlled trial was conducted to investigate the effect of 6 months LMHFV after a distal radius fracture in elderly patients. 200 patients will be recruited and randomized to control or LMHFV (n=100 per group). LMHFV was provided at 35Hz, 0.3g, 20 min/day, 5 days/week. Assessments included fall rates, postural stability by Biodex Balance System, timed up-and-go test (TUG), quadriceps muscle strength, compliance (confirmed by smart card) and adverse events. Time-points were measured at baseline, 6 weeks, 3 and 6 months. ANOVA used to compare means. Chi-square tests to compare proportions for categorical variables and Fisher’s exact test for categorical variables.

Results
Currently, 160 patients completed protocol for interim analysis. 4 patients dropped out from control group and 5 patients dropped out from LMHFV group. There were no significant differences between baseline characteristics. 95% compliance of LMHFV was documented.
Falls occurred significantly less in LMHFV group with 2 times compared to 9 times in control group at 6 months. No adverse events were recorded.
There was significant improvement with LMHFV at 6 months for postural stability. TUG was significantly improved at 10.8 2.3s compared to control at 6 months at 12.8 3.4s. Quadriceps muscle strength was also significantly improved at 3 and 6 months.

Conclusions
Our results showed decreased falls and improved postural stability with LMHFV. Future clinical practice may adopt LMHFV in Fracture Liaison Services for prevention of falls and potentially imminent risk of fractures.
