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.

Outcome Measures

Primary Outcomes (1)

• Strength device

  The strength of the cylindrical grip movement was quantified through the door handle device, the spherical grip strength through the tap device, the hook grip strength through the vertical door pull handle, the pulp-pulp pinch strength through the linear switch device and the pulp-side pinch strength through the key device. The test was quantified 3 times with a 1 minute interval between each test and the force throughout the range of motion. Unit of measure: newton (N).

Study Arms (1)

Hand strength

EXPERIMENTAL

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.

Interventions

handgrip strength 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.

Also known as: Jamar dynamometer

Hand strength

Door handle device DEVICE

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

Hand strength

Tap device DEVICE

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

Hand strength

Door pull handle DEVICE

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

Hand strength

Linear Switch device DEVICE

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

Hand strength

Door Key device DEVICE

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