ObjectiveSelective tibial neurotomy (STN) has been indicated for spastic equinus foot (SEF); however, the impact of this procedure on quality of life and activities of daily living has not been evaluated in detail. This study aimed to evaluate the surgical outcomes of STN and its effect on SEF accompanied by pain.MethodsWe evaluated 26 patients (mean age: 59.6 ± 15.2 years; 14 men and 12 women) who underwent STN for SEF, 10 of whom complained of spontaneous pain preoperatively. We used the following scales for clinical evaluation: the Modified Ashworth Scale, Medical Research Council (MRC), 10-m walking test, Functional Independence Measure, and numeric rating scale for pain. These scales were evaluated preoperatively and postoperatively. Differences in clinical characteristics were compared between the 10 patients with pain and the 16 patients without pain.ResultsSignificant differences were observed in all evaluation scale scores except for the Functional Independence Measure, and no serious adverse events were reported. Pain intensity was significantly improved from 6.4 ± 2.0 to 2.7 ± 2.3 (P < 0.05). An analysis showed that the preoperative mean Medical Research Council score of ankle movement was significantly lower in patients with pain but recovered to the same level postoperatively at the 6-month follow-up.ConclusionsOur study showed significant improvements in spasticity and its associated symptoms, and STN effectively addressed spastic pain and motor weakness. Among various treatment modalities, STN may be positively indicated for patients with spastic pain in the lower leg.Copyright © 2022 Elsevier Inc. All rights reserved.
