Dorsal flexion maneuver of the phalanx of the first
metatarsophalagic joint with the use of running socks

The movement of the dorsal flexion of the first metatarsophalagic joint (MTPJ) is necessary for a correct gait. Its
restriction generates an alteration in the establishment of the windlass mechanism, the Jack´s test allows to assess if
there is alteration of movement. The use of compressive running socks is commonly used in the population, but we do
not know how these socks influence the mechanism of windlass.Objectives: the aim of this study is to measure the
amount of force needed to perform the dorsal flexion of the first MTPJ with the use of special compressive running
socks.Methods: The sample size of this research was 30 subjects. Jack's test was measured with a new device,
consisting of an algometer and a lever system. The necessary force was calculated with the use of two types of
compressive running socks.Results: There were statistically significant differences with the use of special compressive
running socks with orthopedic corrections during the Jack´s test measured with the new device(13.33N ±3.54,
p<0.001).Conclusions: The use of special compressive running socks with orthopedic corrections decreases the force
needed measured in Newtons to perform the dorsal flexion of the first MTPJ during the Jack´s test. The new device for
measuring dorsal flexion of the first MTPJ is a valid and reliability tool.
