The Prediction Of Need Of Using Ankle-Foot Orthoses In Stroke Patients Based On Findings Of A Transcranial Magnetic Stimulation Study

Ankle-foot orthoses (AFOs) are widely prescribed for stroke rehabilitation. We investigated the potential of transcranial magnetic stimulation (TMS) at an early stage, a?ter stroke, to predict the need of using AFOs in stroke patients. We recruited 35 patients who could walk with intermittent support of one person or independently 3 months a?ter onset of stroke. The patients included in the study were classified into two groups: a TMS (+) group (n =10), in which motor-evoked potential (MEP) in the a?fected tibialis anterior (TA) was present, and a TMS (-) group (n = 25), in which the MEP in the a?fected TA was absent. Three months a?ter the onset of stroke, we investigated whether patients were using AFOs or not. We also checked the motor function of the a?fected lower extremity using the Medical Research Council (MRC) scale. A?ter 3 months of onset of stroke in the TMS (+) group, 4 patients (40%) were using an AFO during ambulation. In the TMS (-) group, 21 patients (84%) were using an AFO. The probability of using AFOs in the 2 groups were significantly di?ferent. Additionally, 3 months a?ter the onset of stroke, the MRC scores of ankle dorsi?lexor power, on the a?fected side, were significantly higher in the TMS (+) group. Early TMS evaluation of the corticospinal tract to the TA appears to be useful for predicting the need of using AFOs in stroke patients during the recovery phase.
