Purpose: This study aims to investigate and compare the efficacy of two training programs of weight-bearing on a mini-trampoline, and ankle exercise therapy on foot-ankle functionality in people with peripheral neuropathy.
Methods: The present research is a clinical trial study that has been conducted using two intervention groups and one control group. The statistical population of this study includes 48 women living in Tehran City, Iran with type 2 diabetes and moderate or severe neuropathy. The Michigan neuropathy screening instrument (MNSI) and foot health status questionnaire (FHSQ-BR) were used to collect data. The first experimental group performed mini-trampoline exercises, while the second group performed ankle therapeutic exercises at home for eight weeks. Data were analyzed using analysis of covariance (ANOVA) and correlated t-test.
Results: The findings showed that mini-trampoline exercise and ankle exercise therapy had a significant effect on relieving foot pain (P<0.05), as well as improving foot functionality (P<0.05) and overall foot health (P<0.05) in both intervention groups compared to the control group. Also, the results showed that ankle exercise therapy was more effective than mini-trampoline exercise in two variables of foot pain and foot functionality (P<0.05). Both training programs showed significant effects on the ankle range of motion (P<0.05), while, no significant difference was observed between the two intervention groups for the range of motion of the ankle (P<0.05). Moreover, mini-trampoline exercise and ankle exercise therapy revealed a significant effect on the range of motion of the metatarsophalangeal joints compared to the control group (P<0.05). In the range of motion of dorsiflexion of the right foot, mini-trampoline exercises were more effective than therapeutic exercises, while regarding the variable of dorsiflexion of the left foot, the effectiveness of ankle training intervention was more than trampoline (P<0.05). Both trampoline exercise and ankle therapeutic exercise interventions had a significant effect on ankle strength, but no difference was observed in plantar flexion strength of the right foot between the two intervention groups. However, the mini-trampoline intervention was more effective than the ankle exercise therapy intervention for the three variables of the hallux dorsiflexion strength of the hallux and plantar flexion strength of the left foot (P<0.05). Both training interventions were effective on the variable of right and left hallux flexion strength (P<0.05). The efficacy of none of the two interventions on the right and left hallux extension strength was confirmed; the effectiveness of both interventions on the right and left hallux flexion strength was similar and no significant difference was observed (P>0.05). No significant difference was found in the control group after 8 weeks for the relevant variables (P>0.05).
Conclusion: Exercises on the mini-trampoline and ankle therapeutic exercises at home can be effective in improving patients’ quality of life as a simple, affordable, low-risk, and quick-improvement treatment program that focuses on the use of segmental exercises for foot functionality.
