Mensuration of elbow joint angle in the application of the neural tension test in individuals with leprosy

Abstract

Leprosy is a chronic and granulomatous disease, which affects skin and peripheral nervous system by invasion of Mycobacterium leprae in the immune system. The objective of this study was to evaluate the ulnar neural tension test in leprosy patients. In applying the test of neural tension, it was done goniometry and photometry to measure the angle of the elbow joint, and to perform the photometry we used a Samsung camera, 12.1 Mega pixels, and the data were analyzed using Corel Draw Software X5 (Microsoft®). We selected 44 individuals of Pro-Hansen Foundation, with an average age of 48.13±12.55 years, divided in three groups: G1, G2 and G3. G1 consisted of leprosy volunteers with preserved sensibility; the G2, the ones with leprosy and with no sensibility; and G3 was control group. In goniometry, it was found significant difference (p<0.05) when comparing the G1 and G2 with control of both the right and left limb, but no difference was found when comparing the two leprosy groups. In photometry, it was found difference between G2 and the control and bilaterally between the G1 and control on the left side. Comparing the right and left limbs, difference was not found in any group. Patients with leprosy showed a decrease in range of movement of elbow flexion in ulnar neural tension test in both sides when compared to the control group.
