Resistance Exercise in Woman With Primary Sjörgen Syndrome.

Study Overview
=================
Brief Summary
-----------------
To analyze the effectiveness of 16-week resistance exercise in daily motor behavior and functional fitness in women with Primary Sjögren's Syndrome. The present study presents as hypothesis that a supervised resistance exercise program is effective and safe in improving the functional fitness and quality of life of patients with Primary Sjögren's Syndrome, making them more physically active, contributing positively to the capacity to perform daily life activities as household and / or professional tasks.

Detailed Description
-----------------
Sjögren's syndrome (SS) is a systemic autoimmune inflammatory disease that affects the exocrine glands and less frequently the internal organs, presenting intense lymphoplasmacytic infiltration mainly in the epithelium of the involved tissues, leading to the destruction and loss of the secretory function. SS can manifest itself in isolation, without association with other diseases, in this situation it is called Primary Sjögren's Syndrome (PSS), being considered the second most common autoimmune rheumatic disease, prevalent in women (9: 1). The inflammatory process can affect any organ, resulting in a generally severe clinical condition, and may involve the musculoskeletal, pulmonary, gastrointestinal, hepatic, hematological, vascular, dermatological, renal and neurological systems, leading to an evident decline of the physical functions with decrease in aerobic capacity, muscular strength, joint mobility and static balance, as well as psychological and social deficit. Patients with PSS also present a marked physiological characteristic with a high level of fatigue. Thus, resistance exercise becomes a non-drug strategy, aiming to improve musculoskeletal fitness, allowing the execution of daily activities with more independence, autonomy and safety, while influencing the patient's functional fitness. The aim of the present study is to analyze the effectiveness of resistance exercise in daily motor behavior and functional fitness in women with Primary Sjögren's Syndrome. After the use of actigraphy for 15 days, equipment that measures the level of daily physical activity, and evaluation of functional fitness, volunteers underwent a supervised resistance exercise program for 16 weeks. The following muscular clusters were exerted: latissimus dorsi, deltoid, pectoralis major , triceps brachialis, biceps brachialis, quadriceps, hamstring, thigh adductor muscles, thigh abductor muscles and gastrocnemius. The subjects performed in each exercise 3 sets of 10 maximum repetitions. The training sessions were held twice a week.

Design Details

Primary Purpose: Supportive Care
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: The division of the groups was obtained through randomization through a computer program. An opaque envelope containing the group allocation was given to the volunteer by the blind evaluator. After randomization, the sequential numbers were kept in opaque and closed envelopes and, as patients passed the initial evaluations, were allocated to one of the groups.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Exercise<br>Volunteers underwent a supervised resistance exercise program for 16 weeks. The subjects performed 10 exercises with 3 sets of 10 maximum repetitions in each. The training sessions were held twice a week. | Other: Exercise<br>* The following muscular clusters were exerted: latissimus dorsi, deltoid, pectoralis major , triceps brachialis, biceps brachialis, quadriceps, hamstring, thigh adductor muscles, thigh abductor muscles and gastrocnemius.<br>|
| No Intervention: Control<br>Volunteers in this group were instructed not to perform systematic physical exercises for 16 weeks (the same period of the GEX group training program), and only the SSP medication treatment was maintained, and they were followed up during the study period. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in functional fitness | The protocol consists of a sequence of 7 tests that aim to mimic the neuromotor and cardiorespiratory needs involved in the daily life activities. This battrey test was designed and validated to evaluate the elderly without a ceiling effect, ensuring that the physical aspect measured represents the maximum of the individual. The physiological components evaluated, based on the physical abilities performed in the daily activities are: upper and lower limb strength, aerobic capacity, upper and lower limb flexibility, as well as motor agility / dynamic balance. In addition, the authors added the body mass index (BMI), to estimate the body composition. | The subjects were assessed in 2 moments: before entering the resistance training program and after 16 weeks of intervention. | 
| Change in daily motor activity index | To verify the daily movement index of the subjects we used a device called an actigraphy or actimeter. | The subjects were assessed for 15 consecutive days belonging to the habitual routine of the volunteers. It was used in 2 moments: before entering the resistance training program and after 16 weeks of intervention. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quality of life estimate | To evaluate the quality of life, the Medical Outcomes Study SF-36, a generic questionnaire was translated and validated for the Brazilian population (Ciconelli, 1999). To evaluate, in a generic way, the quality of life. It is a multidimensional instrument composed of 36 items evaluating in 8 dimensions thus distributed: 10 items related to functional capacity; 4 physical appearance items; 2 items on pain; 5 items related to general health status; 4 items on vitality; 2 items with respect to social aspects; 3 items on emotional aspects; 5 items related to mental health and one more question of comparative evaluation between the current health conditions and that of a year ago. | The subjects were assessed in 2 moments: before entering the resistance training program and after 16 weeks of intervention. | 
| Estimates of disease activity | ESSDAI - Sjögren's Syndrome Disease Activity Index is a questionnaire that investigates the activity of SSP disease and has 12 domains (constitutional, lymphadenopathy, glandular, articular, cutaneous, respiratory, renal, muscular, peripheral nervous system, central nervous system, hematological, biological) (Seror et al. 2009). It was developed from a consensus study of the EULAR (European League Against Rheumatism) and the American group. His cross-cultural adaptation and validity for the Brazilian Portuguese language was performed by the Sjögren's syndrome clinic of the Rheumatology department of the Cassiano Antônio de Moraes University Hospital (HUCAM), in Vitória, Espírito Santo (Serrano et al., 2013). Disease activity is classified into 3 levels: mildly active, moderately active and highly active. | The subjects were assessed in 2 moments: before entering the resistance training program and after 16 weeks of intervention. |
