Avaliação do equilíbrio funcional e qualidade de vida em pacientes com espondilite anquilosante

Abstract

Objective: To assess functional balance and quality of life among patients with ankylosing spondylitis. Type of study: Crosssectional. Methods: Sixty individuals were evaluated: 30 with ankylosing spondylitis (AS) and 30 healthy individuals-using the Brazilian version of the Berg Balance Scale, SF-36 questionnaire for the assessment of quality of life and a visual analogue scale (VAS) for pain. Results: The score of the scale of Berg was respectively for groups EA and control of 48.83 and 55.5 with statistically significant difference. There was a positive correlation between the Berg Scale and the VAS (r = 0,469) and between this scale and the functional capacity domain of the SF-36 (r = 0,648). There was a negative correlation between the VAS and following domains of the SF-36: functional capacity (r =-0,753), physical aspects (r =-0,612), overall health (r =-0,607), pain (r =-0,827) and vitality (r =-0,532). Conclusion: Patients with AS exhibit worse functional balance, a poorer quality of life and more pain than healthy individuals. Poorer balance was correlated to pain and worse functional capacity.

Equilíbrio estático e dinâmico no indivíduo com espondilite anquilosante: revisão da literatura

“…All of them involved fi eld research, but the ways of analyzing postural control and balance differed, hindering the data analysis as a whole. To assess balance, the instruments used were the Berg Balance Scale (BBS), 9 the study of the center of gravity displacements with force plataform, 8 and the Bath Ankylosing Spondylitis Metrology Index (BASMI). 6 The major postural disorder found was an increase in thoracic kyphosis and hip fl exion, leading to the forward displacement of the body's center of gravity.…”

“…Because of that position, compensation of knee fl exion and ankle plantar fl exion occurred to maintain balance. [6][7][8][9] Because of those postural changes, two authors have found worse balance in individuals with AS, and one of them has reported a correlation between balance and pain. 6,9 The authors have not ruled out the hypothesis that, with disease progression, the patients could not compensate the postural changes that lead to imbalance.…”

“…The characteristic changes in patients with AS include straightening of the lumbar lordosis, accentuation of the thoracic kyphosis, and head protraction, manifesting as an increase in upper cervical extension and lower cervical fl exion, in accordance with the fi ndings of the studies assessed. 10 Souza et al 9 have reported worse balance in individuals with AS as compared with that of healthy individuals, in addition to a positive correlation between pain (assessed by use of the pain Visual Analogue Scale) and balance (assessed by use of the BBS). Aydog et al 6 have reported no balance defi ciency, but a positive correlation between the occipital-wall distance (BASMI) and the mediolateral stability measure assessed by use of the Biodex Stability System (BSS).…”

“…The studies by Souza et al, 9 Bot et al, 8 and Murray et al 7 have not reported some important data, such as the exact time the patient had to remain in the required posture, the position of the shoulders when measuring the occipital-wall distance and that of the arms when measuring chest expansion, whether there was an interval between the tests, and at which day time the assessment was performed. The interval between assessments, aiming at eliminating the effect of muscle fatigue, and the day time of the assessment, because of morning stiffness, should be controlled because they can infl uence the results.…”

Postural Control and Balance in Ankylosing Spondylitis

“…Souza et al reported that postural balance was worse in AS patients than in healthy individuals and a positive correlation was determined between pain and balance [32].…”
