          Abstract

          Spasticity is a determining for functional loss following ischemic stroke. OBJECTIVE: To detect possible predictive factors for its occurrence. METHOD: Demographic, clinical and tomographic data on 146 stroke patients were analyzed. RESULTS: Spasticity was noted more frequently among patients who underwent physiotherapy (p<0.0001; OR=19.4; 95% CI: 4.4-84.5), those who underwent such treatment for long periods (p=0.028; OR=4.80; 95% CI: 1.1-8.3) and those with manual work (p=0.041; OR=2.2; 95% CI: 1.02-4.6), lower income (p=0.038), pain complaints (p<0.0001; OR=107.0; 95% CI: 13.5-847.3), appearance of pain at the same time as spasticity (p<0.0001), previous vascular disease (p=0.001; OR=4.2; 95% CI: 1.7-10.3), muscle weakness (p<0.0001; OR=91.9; 95% CI: 12.0-699.4), extensive lesions as seen on tomography (p=0.01) and lesions affecting more than one cerebral lobe (p=0.018). Manual work had a relative risk of 2.9; previous stroke 3.9, and extensive lesion 3.6. CONCLUSION: Spasticity affected 25% of the patients, and was associated with: manual work, previous stroke, extensive lesions, decrease in individual income, underwent physiotherapy, underwent physiotherapy for longer period, pain complaints, the pain started simultaneously with the spasticity, presented changes in strength.

          A espasticidade é fator determinante para perda funcional após o acidente vascular cerebral isquêmico (AVCI). OBJETIVO: Detectar possíveis fatores preditivos para a ocorrência da espasticidade. MÉTODO: Foram analisados dados demográficos, clínicos e tomográficos de 146 pacientes pós-AVCI. RESULTADOS: Na análise univariada a espasticidade foi notada com maior freqüência em pacientes que realizaram fisioterapia (p<0,0001; OR=19,4; 95% CI: 4,4-84,5), com maior tempo de duração desse tratamento (p=0,028; OR=4,80; 95% CI: 1,1-8,3) e que realizavam trabalho braçal (p=0,041; OR=2,2; 95% CI: 1,02-4,6), renda menor (p=0,038), referência de dor (p<0,0001; OR=107,0; 95% CI: 13,5-847,3) e seu aparecimento simultâneo à espasticidade (p<0,0001), acidente vascular cerebral (AVC) pregresso (p=0,001; OR=4,2; 95% CI: 1,7-10,3), fraqueza muscular (p<0,0001; OR=91,9; 95% CI: 12,0-699,4), lesão tomográfica extensa (p=0,01) e lesão afetando mais de um lobo cerebral (p=0,018). Na análise de regressão multivariada a atividade braçal apresentou risco relativo de 2,9; acidente vascular cerebral prévio com risco relativo de 3,9 e lesão tomográfica extensa risco relativo de 3,6. CONCLUSÃO: A espasticidade afetou um quarto da população estudada e esteve associada ao trabalho braçal, AVC pregresso, lesões tomográficas extensas, diminuição da renda individual, realização de fisioterapia, realização de fisioterapia por um período maior, presença de dor, surgimento da dor simultânea à espasticidade e alteração da força.

            Structural and functional changes in spastic skeletal muscle.

            This review summarizes current information regarding the changes in structure or function that occur in skeletal muscle secondary to spasticity. Most published studies have reported an increase in fiber size variability in spastic muscle. There is no general agreement regarding any shift in fiber type distribution secondary to spasticity. Mechanical studies in whole limbs as well as in isolated single cells support the notion of an intrinsic change in the passive mechanical properties of muscle after spasticity in addition to the more widely reported neural changes that occur. Evidence is presented for changes within both the muscle cell and extracellular matrix that contribute to the overall changes in the tissue. Taken together, the literature supports the notion that, although spasticity is multifactorial and neural in origin, significant structural alterations in muscle also occur. An understanding of the specific changes that occur in the muscle and extracellular matrix may facilitate the development of new conservative or surgical therapies for this problem.

              The impact of stroke.

              The socio-economic impact of stroke is considerable world-wide. Stroke is assuming an increasing impact in terms of media attention, patient and career knowledge, service developments and research. It is estimated that there are 4.5 million deaths a year from stroke in the world and over 9 million stroke survivors. Almost one in four men and nearly one in five women aged 45 years can expect to have a stroke if they live to their 85th year. The overall incidence rate of stroke is around 2-2.5 per thousand population. The risk of recurrence over 5 years is 15-40%. It is estimated that by 2023 there will be an absolute increase in the number of patients experiencing a first ever stroke of about 30% compared with 1983. There is a total prevalence rate of around 5 per thousand population. One year after a stroke, 65% of survivors are functionally independent, stroke comprising the major cause of adult disability.
