PURPOSE: To evaluate the immediate orthotic, total and therapeutic effects of
functional electrical stimulation (FES) neuroprosthesis use on clinic based
measures of gait and function in children with hemiplegic cerebral palsy.
METHODS: Eleven children (mean 9 years 11 months) participated in an FES
neuroprosthesis (Ness L300) intervention (4 week accommodation period followed by
12 weeks of daily use) and were assessed at baseline and post in stimulation off
and stimulation on conditions. Measures included clinic based outcomes of gait
and function. RESULTS: No significant immediate orthotic effects were observed.
Significant (p < 0.01) total effects were noted for dorsiflexion at initial
contact, Six-Minute Walk Test (6MWT), and walking speed. A significant
therapeutic effect was found for steps off path on the Standardized Walking
Obstacle Course (SWOC). CONCLUSIONS: Results support previous findings of
neuroprosthesis total effects on gait and provide some evidence for effects on
function. Therapeutic effects remain unclear. Implications for Rehabilitation In
this study, children with hemiplegic CP did not demonstrate immediate
improvements in gait or function at their first clinic visit using the FES
neuroprosthesis device suggesting one visit using the device is not sufficient to
determine potential benefits. Over time with daily use of the FES
neuroprosthesis, ankle dorsiflexion in swing and at initial contact, walking
speed and endurance increased with the device worn. Overtime, no carryover
effects in ankle dorsiflexion in swing and at initial contact were noted at the
end of the intervention period with the device off. Clinicians should consider
purchasing units to loan or rent to individuals to trial a device at home before
determining long-term potential for benefit.
