Abstract

Polineuropathy is a complication from Diabetes Mellitus that have been very challenging for clinicians. It brings high costs for public health and huge impact on patients'quality of life. Prevention actions are still the most important stages to avoid plantar ulceration and amputations that are the most devastating endpoint of the disease. There are some interventions that show an improvement in gait quality, confidence and quality of life, but there is not yet evidence of an effective therapeutic intervention for recovering musculoskeletal functions and foot rollover during gait that can potentially reduce ulcer incidence or its recurrence. We present an intervention protocol with simple tasks that allow the patient to practice the exercises at home, without the need for professional supervision, aiming at recovering the most impaired segments due to polineuropathy. If these exercises show any benefit, they could be indicated as a complementary treatment for the disease. Methods/Design: a randomized controlled trial, blind assessment, was designed to study the effect of a physiotherapy intervention on foot rollover during gait, range of motion, muscle strength and function of the foot and ankle, and balance confidence. The main outcome is plantar pressure during foot rollover and secondary outcomes are kinetic and kinematic parameters of gait, neuropathy signs and symptoms, foot and ankle range of motion and function, muscle strength and balance confidence. The intervention is carried out for 12 weeks, twice a week, for 40-60 minutes each session. The follow-up period is 24 weeks of baseline condition. We calculatied the effect size of 0,36 (moderate effect size) to detect differences on the primary outcome. A sample size of 46 subjects is needed to provide 81% power, assuming an alpha level of 0.05 and an statistical design of F test of repeated measures (between and within effects). The statistical analysis will be based on intention-to-treat analysis and general linear models of analysis of variance and repeated measure will be used to detect treatment-time interactions. This trial is currently recruiting patients since August 2011. Trial registration: ClinicalTrials.gov identifier: NCT01207284. (AU)
