Mani D, et al. - Researchers determined the impact of two interventions that involved neuromuscular electrical stimulation (NMES) applied to the triceps surae muscles on the mobility and muscle function of older adults. Changes in motor function were assessed during a 6-week intervention, implemented in healthy older adults (73.5 ± 4.8 yrs), comprising 3 weekly sessions of either narrow- or wide-pulse NMES. They found improvements in the motor function could result from NMES but the time course of the adaptations varied across the mobility tests. They observed that following 3 wks of NMES (Week 4), time to walk 400 m decreased and maximal walking speed increased but no further change was noted at Weeks 7 and 10. Up to Week 7, a progressive decrease was noted in the time to complete the chair-rise and rapid-step tests but no change was evident further at Week 10. Moreover, the increase in plantar flexor strength was only observed at Week 7.
