The motor ability of the upper limb is of extreme importance for the performance of functional tasks present in the activities of daily life of an individual. Functionality is related to anatomical integrity, muscle strength, sensitivity and dexterity. Injury conditions affecting the upper extremity can lead to severe functional impairment, and accurate assessment is required to determine the most appropriate treatment in rehabilitation. To evaluate the function of the hand, it is important to use the performance tests through the simulation of activities of daily living as the functional test of the Jebsen-Taylor hand (TFJT). The objective of the study is to describe the normative values and to evaluate the test-retest reliability of the Brazilian version of TFJT in Brazilian asymptomatic individuals for upper limb dysfunctions between 18 and 60 years of age, regardless of the laterality. The methods consist of the standardized application of the specially developed Brazilian version of all 7 TFJT subtasks - write, turn cards, pick up small objects, simulate feeding, stack objects, pick up large and light and also large and heavy objects. The tests will be performed bilaterally and the time of each task will be recorded in seconds through a timer, in a sample of 240 asymptomatic volunteers. The volunteers will also be submitted to a standardized evaluation to characterize the sample, such as age, sex, occupational activity, dominance, and a test of isometric muscular strength of the pinch three points, lateral and tip to tip and grip strength with the Jamar® dynamometer. The test-retest reliability will be analyzed after an hour of interval, stratifying the values by age group of 20-29, 30-39, 40-49 e 50-59 years and sex through ICC and internal consistency, and ANOVA for groups comparations with SPSS software version 20.0, p <0.05.
