[Nutritional evaluation and physical functional ability in scleroderma patients].
BACKGROUND
Systemic Sclerosis (SSc) is an inflammatory disease that decreases functional capacity through muscular atrophy, skin sclerosis and loss of joint function. Scleroderma patients suffer from movement's restriction. In addition, the disease affects the nutritional status, compromising the quality of life in varying degrees. The gastrointestinal involvement appears to be the main responsible for the nutritional impairment.


OBJECTIVE
To evaluate the physical and nutritional status of patients with SSc.


METHODS
We conducted a cross-sectional and descriptive study in 20 patients with SSc. All patients were evaluated in Physioteraphy Clinic of the Catholic University of Paraná, from July 2003 to April 2004. The evaluation was performed by Bioimpedance Body (BIA), the questionnaires Nutritional Risk Assessment (Determine), Mini Nutritional Assessment of Aging and Health Assessment Questionnaire (HAQ) and Visual Analogue Scale (VAS) for pain. The work muscle ability was assessed by measuring the peak torque of flexor and extensor muscles of the elbow in the isokinetic dynamometer Cybex Norm model 7000. We have calculated the mean and standard deviation for each variable analyzed, in addition to the percentage of peak torque deficit.


RESULTS
The values of the VAS ranged from zero to 97.8 mm (mean: 48.9 +/- 32.9 mm). The HAQ scores ranged from zero to 2.75 (average: 0.95 +/- 0.8). The average BMI was 22.4 +/- 3.9 kg / m2. The average deficit of mass was: 1.3 +/- 2.1 kg. Ten patients had high nutritional risk. 1 patient was malnourished and 15 were at high risk for malnutrition. The average peak torque to the muscle groups of elbows was 19.2 +/- 5 N / m to the flexor and 21.9 +/-6.6 N/m for the extensors, with an average deficit of 17% and 13% for the both groups.


CONCLUSIONS
We found that SSc patients were in poor nutritional status and had decreased functional and physical capacity by the weakening of the muscles of the elbow demonstrated by the isokinetic evaluation. We concluded that our SSc patients were at high risk for malnutrition and this may indicate that scleroderma patients need a better nutritional orientation. We do consider that SSc patients also must be included in physical activity programs in order to achieve better physical performance.
