Materials and Methods: This study of 40 subjects compares foot and ankle manipulation and mobilization with placebo (de-tuned ultrasound) in the management of Morton’s neuroma. Outcome measures included the Numerical Pain Rating Scale (NRS)101, a Short-form McGill Pain Questionnaire (SFMPQ), the Foot Function Index - Pain (FFIP) and the Foot Function Index - Disability (FFI-D), Algometer pain pressure threshold, and pain pressure tolerance.
Results: Data were statistically analyzed for significance at a 95% confidence level with alpha (á) set at 0.05. The NRS-101 showed Group B (manipulation and mobilization) to have a statistically significant improvement in perceived pain levels compared with Group A (placebo)at 6 weeks (mean NRS 25.4 and 40.7 respectively, p = 0.03). Algometry pain pressure threshold and tolerance were also found to be statistically significantly improved in Group B compared with Group A (p = 0.02 and p = 0.02 respectively). Power was adequate for the NRS 101 primary outcome measure. No other statistically significant differences in subjective outcome measures (SFMPQ, FFI-P, and FFI-D) were found between the 2 groups.
Discussion: There is evidence that the addition of the manipulative treatment protocol was more efficacious in reducing subjects’ perception of pain, but some limitations do exist.
Conclusion: These findings suggest the possibility of shortterm relief and efficacy for manipulation and mobilization in the treatment of Morton’s neuroma.
