Fall Prevention Efforts at the University of Dayton

The UD Engineering Wellness and Safety Lab focuses on balance as a fall risk-factor.
Individuals with balance impairment are 1.6 – 5.4 times more likely to fall.
AGS, BGS, AAOS. JAGS. 2001.

Increased amount of sway or speed of sway is often the sign of balance deficit/increased fall risk.
Using engineering tools, we can measure balance deficits and improvements.

Center of Pressure Stabilogram
Through this type of research we were able to develop a method for clinical screening fall risk.
We also examined the effect of carrying grocery bags on postural stability.

We also focus on improving balance in neurological populations at high risk of falls – Kickboxing & MS
Pre – and Post – Program Measures:
•Timed Up & Go (TUG)
•Berg Balance Scale (BBS
•Dynamic Gait Index (DGI)
•Ten Meter Walk Test
•Activities of Balance
Confidence Scale(ABC)
•Posturography – A/P and M/L
COP Sway Range
•mCTSIB (30 seconds
each trial)
•Limits of Stability (2
trials)

We’re also looking at monitoring physical movement in the real world
