Common symptoms of chikungunya fever are persistent arthritis and arthralgia, such symptoms can lead to impairment in functionality. The objective of this study is to evaluate the efficacy of a resistance exercise protocol on the functionality of individuals with chronic musculoskeletal manifestations of Chikungunya fever. Quality of life, number of painful joints, intensity of pain, number of recurrence of exacerbation and thermography are secondary outcomes that will also be evaluated. The protocol uses elastic resistance to strengthen muscle groups that stabilize the main joints affected by Chikungunya Fever. The sessions will be 2 times a week for 12 weeks. The control group will not be submitted to the intervention during the 12 weeks, being contacted through telephone calls. After the reevaluation at the end of the 12 weeks the control group will perform the same protocol. The sample will be characterized and the effect size and the mean difference will be calculated. Intention-to-treat analysis and rate of adherence will also be calculated.

Change in functionality through a walk test
Performance in seconds of the 40m Fast-paced Walk Test, the longer the time in seconds, the worse the outcome. The normative values for women between 50´s and 60´s age range are 19,90 to 22,60 seconds, and for men in the same age range between 19,32 and 20,73 seconds.
Time frame: Assessed before intervention, in 6 weeks and after the 12-week intervention
Change in functionality through a stair climb test
Performance in seconds of the 4 step stair climb test, the longer the time in seconds, the worse the outcome. The normative values mean for healthy women is 10.22 seconds and healthy men is 8.72 seconds
Time frame: Assessed before intervention, in 6 weeks and after the 12-week intervention
Change in functionality through a chair stand test
Performance in number of time the patient stands in the 30-Second Chair Stand Test, the higher the number of the better the outcome, the mean for women in the 60´s age range is from 11 to 17 times and for men in the same age range is from 12 to 19 times
Time frame: Assessed before intervention, in 6 weeks and after the 12-week intervention
Change in functionality of upper limbs
Function of upper limb trough specific score of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire with 30 items with responses range from 1(not limited) to 5 (extremely limited) and two optional sections, responses are used to calculate a scale score ranging from 0 (no disability) to 100 (most severe disability)
Time frame: Assessed before intervention, in 6 weeks and after the 12-week intervention
Change of score on the Medical Outcomes Study 36 - Item Short - Form Health Survey questionnaire
quality of life assesment through Medical Outcomes Study 36 - Item Short - Form Health Survey questionnaire that consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0 (maximum disability) to 100(no disability) scale
Time frame: assessed before intervention, in 6 weeks and after the 12-week intervention
Change in the intensity of pain: VAS
number correspondent to the intensity of pain using visual analogic scale from 0(no pain) to 10 (maximum pain)
Time frame: assessed in every intervention day (twice a week for 12 weeks)
Change in the number of painful joints
assessed though a tender joints count, the higher the number the worse the outcome
Time frame: assessed before intervention, in 6 weeks and after the 12-week intervention
Change in the number of exacerbation recurrences
the higher the number the worse the outcome
Time frame: assessed through the 12-week intervention period
Change in temperature of areas of interest (joints)
assessed with thermography through index of thermic distribution seen through software FLIR Tools 5.3. the higher the temperature the worse the outcome
Time frame: assessed before intervention, in 6 weeks and after the 12-week intervention
Change in patients global impression of change
number corresponding to answer of the Patient Global Impression of Change (PGIC) questionnaire being 1 (no change) the worst outcome and 7 (a lot better) the best outcome
Time frame: assessed before intervention, in 6 weeks and after the 12-week intervention
Number of patients reporting adverse effects
Unexpected effects reported by patients potentially associated with the intervention such as worsening pain, swelling, stiffness or other
Time frame: Reported through study completion, an average of 1 year
Change in muscle strength
Performance in the repetition maximum test (1RM) for every exercise, the higher the value the better the outcome
Time frame: Assessed every two weeks during the 12-week intervention period
