| Outline of Final Research Achievements |
We studied the effects of repetitive tibial nerve stimulation (RTNS) on neurogenic claudication and F-wave conduction in a total of 45 patients with central lumbar spinal stenosis (LSS) as compared with 13 age- and sex-matched healthy volunteers. A conditioning RTNS consisted of 0.3 ms in duration and of an intensity 20% higher than the motor threshold, applied at a rate of 5/s for 5 minutes to the ankle.
RTNS significantly increased claudication distance and the F-wave conduction velocity in the LSS group, but not in the control group. In the LSS group, this effect of RTNS on the F-wave was demonstrated not only on the side ipsilateral to RUNS but also on the contralateral side.
Evidenced by this study, RTNS should have practical value in providing a new therapeutic modality for LSS. The technique can be carried out at home with a portable stimulator running on lithium batteries for LSS patients to reduce claudication symptoms.
