Brief Summary

This study developed a system to quantify the functional strength of young adults without motor impairment during grip and pinch movement. Making it possible to know the accuracy of the value of these strength, the range of motion performed and whether the grip force was maintained throughout the range of motion. In addition to checking the functionality, reliability and reproducibility of the system.

Detailed Description

Quantifying grip and grip movement is essential as it allows for a basis in upper limb functionality. However, when there is access, it causes changes in the hands and changes the motor in relation to the force and range of motion, or generates changes in activities of daily living. Thus, a system with 5 devices, where each one the devices were prints in three-dimensional, and instrumented with force sensor for static-dynamic force analysis e potentiometer for analysis range of motion, during the execution of movements cylindrical grip, spherical grip, hook grip, pulp-pulp pinch, and pulp- side pinch in different activities of daily living. Elaborated a data storage interface through MATLAB® software that allows recording the data of each device. For the system functionality tests, 30 volunteers were selected for both sexes, young adults between 20 and 39 years old, students of the Physiotherapy and Graduate courses of the University of Mogi das Cruzes. The tests are divided into two sessions and are repeated after 7 days of the first test

Study Groups

Hand strength

The tests were performed in two sessions lasting 1 hour each. The volunteers used the devices: door handle, tap, door pull handle, switch and door key to quantify hand strength. The tests were performed in two sessions lasting 1 hour each. The volunteers used the devices: door handle, tap, door pull handle, switch and door key to quantify hand strength.

In the first session, the volunteers performed the movements 3 times in each device of daily living activities with the right limb, with a 1-minute rest interval between the 3 measurements. The entire procedure performed in the session was repeated again after 30 minutes to verify the reliability and reproducibility of the Intra-evaluator test. The Inter-rater test was repeated after 7 days by the second rater to analyze reliability between the rater.

Group Type: EXPERIMENTAL

handgrip strength

Intervention Type: DEVICE

First, the hand measurements of each volunteer were evaluated, followed by the measurement of handgrip strength using the Jamar® dynamometer. And later the tests were performed using the system that contains the 5 devices to quantify the hand strength.

Door handle device

Intervention Type: DEVICE

To evaluate the cylindrical grip movement, a door handle was used, which evaluated the full force in the range of motion.

Tap device

Intervention Type: DEVICE

To evaluate the spherical grip movement, a tap was used, which evaluated the full force in the range of motion.

Door pull handle

Intervention Type: DEVICE

To assess the hook grip movement, a door pull handle was used, which assessed the full force in the range of motion

Linear Switch device

Intervention Type: DEVICE

To evaluate the pulp-pulp pinch movement, a switch was used, which evaluated the full force in the movement of the movement.

Door Key device

Intervention Type: DEVICE

To assess the pulp-side pinch movement, a door key was used, which evaluated the full force in the range of motion.
