Clinical Trial Summary

The flatfoot is one of the most common diagnosis in foot. The main goals of its orthotic intervention in adult population are the control of the rearfoot and midfoot movement, the affection of the forefoot position and the minimalization of painful deformities. However, only low-level evidence exists proving the positive effect of orthotic insoles in these patients. The concept of sensorimotor insoles describes besides the simple mechanical correction also the targeted modulation of activity of muscles participated on the correct foot function. The aim of the project is to assess the influence of customized sensorimotor insoles on the lower limbs' kinematics and the activity of lower limbs' muscles in people with diagnosed flexible flatfoot.

The study is designed as a crossover interventional study with experimental and control group (allocation ratio 1:1). Participants' lower limbs' kinematics and muscles activity will be assessed on the baseline measurement, immediately after and 3 months after the intervention with sensorimotor insoles in the experimental group. Also, the subjective perceived effect of intervention will be assessed through the research. After a washout period, experimental and control group will swap their roles and another period of 3 months will follow. Same parameters will be assessed both at the beginning and in the end of each period.

Intervention

Other:
Sensorimotor foot orthoses
The interventional group will receive one customized pair of sensorimotor insoles and will be instructed for their using on a daily bases for the period of 3 months. The duration of using the insoles was established as 1 hour at the day after receiving the insoles. After that, the insoles' tolerance will be assessed based on the email correspondence and further adjustments of insole will be consulted with manufacturer if necessary. Recommended progression in time of using the insoles was established as +1 hour per each day (if possible) with no maximal limit. After 3 weeks, control examination will take place for the control of subjective effect of insoles. Consulting will be offered to the participants through the duration of research. Participants will not undergo any other supplementary treatment (physiotherapy, …) focusing on the flatfoot deformity.

Outcome

Type Measure Description Time frame Safety issue
Other Global Rating of Change Scale Subjective evaluation of overall change in health status on the 11-point scale after 3 month from the baseline, where 0 means "unchanged", -5 means "very much worse" and +5 means "completely recovered". 3 months
Primary Foot kinematics - difference in foot eversion relative to shank during the stance phase of the gait cycle The two-way analysis of variance of the degree of the first peak of foot eversion measured by the optoelectronic system Vicon Vantage (Vicon Motion Systems Ltd., Oxford, Great Britain), where the factors are the "group" (intervention, control) and "time" (baseline, after 3 months). 3 months
Primary Foot kinematics - difference in foot external rotation relative to shank during the stance phase of the gait cycle The two-way analysis of variance of the degree of the first peak of foot external rotation measured by the optoelectronic system Vicon Vantage (Vicon Motion Systems Ltd., Oxford, Great Britain), where the factors are the "group" (intervention, control) and "time" (baseline, after 3 months). 3 months
Secondary Surface electromyography - difference in muscle activity by parameter "mean" during the stance phase of the gait cycle The two-way analysis of variance of the mean activity of the tibialis anterior, peroneus longus and gastrocnemius medialis muscles measured by the TrignoTM Wireless Systems (Delsys Inc., Natick, MA, USA) and normalised to their peak activity during the stance phase of the gait cycle, where the factors are the "group" (intervention, control) and "time" (baseline, after 3 months). 3 months
