Study type | Interventional |
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.

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 |
