Device: Door key device
Registration Number

Brief Summary

This study has developed a peripheral to quantify the functional strength of children without motor change during the movement of grip and pinch. It was possible to know the exact values of these strengths, the range of motion that was made, and also if the grip strength was maintained during all the arc of motion.

Detailed Description

Since childhood, it has been necessary to produce sufficient force to grip and pinch, for performing daily tasks independently; therefore, measurements of these forces end up being useful markers to evaluate the performance and the physical development of the child. It was developed a peripheral containing three devices and instrumented for analyzing the force applied during execution of the cylindrical grip movement, pinch pulp-side and pinch pulp-pulp in different situations of the daily life of the volunteer. The data acquisition interface was developed in a software for data recording. For the peripheral functionality tests, thirty volunteers of both genders were selected. They were also students of the Sports Secretary, with no motor abnormalities, between seven and ten years old.

Primary Outcome Measures
NameTimeMethod
Force15 minutes

The force of cylindrical grip movement was measured through a door handle device, pinch pulp-side through a door key and pinch pulp-pulp movement through a switch. The test was measured 3 times with 1 minute interval and it was measured the strength during all arc of motion. Unit of measurement: Newton (N).

Secondary Outcome Measures
NameTimeMethod
range of motion in angle15 minutes

The test measured the range of motion in a door handle device and in a door key device 3 times with 1 minute interval for each test, in which all the range of motion was measured from its start until its end. Unit of measurement: Angle (º).

range of motion in percentage15 minutes

The test measured the range of motion in a linear switch device 3 times with 1 minute interval for each test, in which all of the range of motion was measured from its start until its end. Unit measurement: Percentage (%).
