Avaliação funcional dos membros superiores em indivíduos amputados de membro inferior

Abstract

Functional assessment provides information on various motor components such as strength, power, balance, mobility and coordination. These capabilities are important both in health and performance. And the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) is a validated test to evaluate the functional performance of the upper limbs. It has reference values for volleyball, tennis, handball and baseball athletes, which favors the monitoring of shoulder rehabilitation programs, when necessary. However, there is no such data in the literature on the performance and validation of the test in people with disabilities (PWD), especially with regard to lower limb amputees since this population uses the upper limbs in an open and closed kinetic chain. than other athletic populations. The main objective of this study was to apply the CKCUEST to lower limb amputees, and the secondary objectives consists of test the reproducibility of the test in lower limb amputees; compare performance in different test adaptation positions; correlate the result with muscular power of the upper limbs and describe the inertial signals during the test. Nineteen physically active amputees without osteoarticular pathologies in the upper limbs were recruited and performed three variations of the CKCUEST, using inertial sensors for movement analysis. One-way ANOVA was used to compare the average values of touches, normalized value and power score of the CKCUEST, as well as the subjective perception of effort (BORG) and visual analogue pain (VAS) scales between the position. Lin’s correlation coefficient of agreement (CCC) was used to evaluate the reproducibility of the test. Person’s correlation was used to correlate SMBT performance with the CKCUEST and with the inertial sensor metrics. The performance results on the CKCUEST in amputees were 28.58 (4.64) the average number of touches, 16.27 (2.64) touches of the normalized value and 97.66 touches/sec of the power score. The variable that differed between positions was subjective perception of effort. Good test-retest agreement was not observed for CKCUEST parameters. The inertial sensor metrics closely linked to the movement carried out in CKCUEST are the dominant frequency and amplitude. The conclusion is that the CKCUEST is a functional test that can be adapted and applied to the population of people with lower limb amputations.
