COMPARISON OF TWO REHABILITATION PROGRAMS FOR PAIN AND FUNCTIONALITY IN PEOPLE IN THE CHRONIC PHASE OF CHIKUNGUNYA
Chikungunya Fever. Chronic Pain. International Classification of Functioning, Disability and Health. Aquatic Therapy. Rehabilitation.
Chikungunya is an arbovirus that can evolve from an acute to a chronic condition, with symptoms remaining, mainly arthralgia. Due to the frequent presence of pain, the disease tends to compromise functional capacity, affecting the activities of daily living and productivity of those affected. The aim of this study is to analyze the effects of two functional rehabilitation programs on the ground versus an aquatic therapy protocol on pain and functionality in people in the chronic phase of chikungunya. This is a randomized clinical trial, carried out in a Physiotherapy School Clinic, located in the municipality of Santa Cruz-RN, two days a week for six weeks, with individuals who have chronic sequelae resulting from chikungunya. The sample was randomly assigned to two intervention groups: the Functional Rehabilitation Group (FRG) and the Aquatic Therapy Group (ATG). For data collection, a questionnaire developed for this study was used with sociodemographic and health information; the Health Assessment Questionnaire (HAQ); and the Brief Pain Inventory (BDI); as well as the Sit and Stand Test (SST), Time Up and Go Test (TUG), and the 8-step Stair Climb Test (SST8). The data was tabulated and analyzed using the Statistical Package for the Social Science (SPSS) software, version 20. A descriptive analysis of the study variables was carried out using measures of absolute and relative frequencies, as well as measures of center and variation. Student’s t-tests were carried out for continuous variables and the corresponding non-parametric Mann-Whitney and Wilcoxon tests for discrete variables, with a significance level of 5%. Cohen’s d was used as a measure of effect size for the t- test, while r was used for the non-parametric tests. Normality was assessed using the Kolmogorov-Smirnov test. Fifty-three individuals took part in the study, 28 of whom were allocated to the GRF and 25 to the GTA, with a predominance of females. In both groups, there was a reduction in pain and improvement in the performance of functional tests, with no significant differences between the groups. The inter-group difference was observed in the HAQ score (p-value = 0.012; d = 0.72), with a significant intra-group difference in the GRF (p-value = 0.000; d = 1.10). The results showed that both functional rehabilitation and aquatic therapy provided significant improvements in pain and performance in functional tests for individuals in the chronic phase of chikungunya. With regard to functional capacity assessed by the HAQ, rehabilitation on the ground was superior to the aquatic therapy protocol, indicating that performing movements that simulate daily activities can promote greater functional repercussions.
