![]() ![]() However, 2 patients experienced pain during gait and their pes varus angle increased during the follow-up period.īoNTA injection improved pes varus angle during gait. The comfortable overground gait velocity was also improved after the injection. It was significantly lower at 6 weeks after the injection during stance phase. The maximum pes varus angle during the swing phase was significantly lower at 2, 6, and 12 weeks after the injection. ![]() The median MAS scores were significantly lower at 2 and 6 weeks after the injection. ![]() Five healthy subjects were also recruited to develop the pes varus/valgus angle as a normal reference. MAS score, comfortable overground gait velocity, and pes varus angle during treadmill walking were evaluated before, 2, 6, and 12 weeks after the injection. Twenty-four hemiplegic patients with spastic pes varus deformity during gait received BoNTA injection into lower limb muscles. The purpose of this study was to evaluate the efficacy of BoNTA injection on pes varus during gait using 3-dimensional motion analysis. There are no reports that quantitatively evaluate pes varus during walking after botulinum treatment. The efficacy of botulinum toxin A (BoNTA) injection on spasticity is usually measured using Modified Ashworth Scale (MAS), but this only evaluates muscle tone at rest and has poor reliability. ![]()
