Assessing Manual Components of Brazilian Children and Adolescents on Hemodialysis

Federal University of Minas Gerais42 enrolled

Overview

The purpose of this study was to assess the handgrip strength; fine motor skills; and hand sensitivity of Brazilian children and adolescents with Chronic Kidney Diseases (CKD). The sample was composed by 42 children and adolescents, 21 on hemodialysis (group A) and the other 21 acted as the control group (group B). The performance of both groups was compared. The outcome measures included Jebsen-Taylor Hand Function Test, the Semmes Weinstein monofilaments test and Jamar Dynamometer.

Outcomes

Primary Outcomes

Jebsen-Taylor Hand Function Test

The manual functioning of upper limbs were assessed by the Jebsen-Taylor Hand Function Test, a standardized test composed by manual tasks based on daily activities. The test is divided into seven sub-tests: (1) writing, (2) flipping cards, (3) small objects lifting, (4) spoon usage, (5) blocks stacking, (6) large and lightweight objects lifting, and (7) large and heavy objects lifting.

Time frame: 30 minutes

Secondary Outcomes

The Semmes Weinstein Monofilaments Test

The Semmes Weinstein monofilaments test was used to evaluate the skin threshold sensitivity. In this test, the damage to the skin sensitivity is classified in colors. The eyes are blindfolded and the nylon monofilaments are applied to the hands of participants until the touch is felt in the dermatomes, regarding the distribution of the ulnar, median and radial.

Time frame: 10 minutes

Jamar Dynamometer

The handgrip strength was checked by the Jamar® Dynamometer, it is constituted by a voltage sealers system which indicates on the device the handgrip strength in kilograms/strength (kg/f) or in pounds/inch. The device was used three times before and after hemodialysis session, and the results were based on the average of the three applications. In the group B, the test was applied 3 times, and obtained average. The dynamometer works in many situations in order to determine the functionality of the hands and is considered a "gold standard" for this purpose.

Time frame: 15 minutes
