Although there were no randomized controlled trials that assessed the effect of electrical stimulation, Bélanger et al. (2000) produced impressive results with a level 2, non-randomized trial which used 1 limb as the treatment and the other as the control limb. Following training, the BMD recovered close to 30% of bone loss when compared with able-bodied values. Stimulation effects only occur over the areas of stimulation and return to baseline within months once stimulation is stopped (Mohr et al. 1997).
- There is level 2 evidence (from 1 prospective controlled trial) (Bélanger et al. 2000) that electrical stimulation either increased or maintained BMD over the stimulated areas.
Electrical stimulation can maintain or increase BMD over the stimulated areas.
