fes has also been found to be useful for treating foot drop in people with multiple sclerosis. the first use was reported in 1977 by carnstam et al., who found that it was possible to generate strength increases through using peroneal stimulation. a more recent study examined the use of fes compared to an exercise group and found that although there was an orthotic effect for the fes group, no training effect in walking speed was found. further qualitative analysis including all participants from the same study found improvements in activities of daily living and a reduced number of falls for those using fes compared with exercise. a further small scale (n=32) longitudinal observational study has found evidence for a significant training effect through using fes.
