Peripheral for Quantify Strength of Children Functional During the Pinch Movement

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.

About this study

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.

Treatment and study plan

Door handle device

Device

To evaluate the cylindrical grip movement, it was used a door handle, which evaluated all the strength at the arc of motion

Linear Switch device

Device

To evaluate the pulp-pulp pinch movement, it was used one linear switch, which evaluated all the strength at the motion displacement.

Door Key device

Device

To evaluate the pulp-side pinch movement, it was used a door key, which evaluated all the strength at the arc of motion

Primary outcomes

  1. Force

    Time frame: 15 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 outcomes

  1. range of motion in angle

    Time frame: 15 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).

  2. range of motion in percentage

    Time frame: 15 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 (%).
