ABSTRACT
INTRODUÇÃO: O período de silêncio cutâneo (PSC) é um reflexo protetor inibitório da coluna vertebral e seus aferentes consistem em fibras nervosas A-delta. Nosso objetivo foi avaliar pacientes com fibromialgia (FM) e controles saudáveis para determinar as diferenças entre os grupos em relação à duração e latência do PSC, e quando presente, determinar se há alguma relação com as características da doença, distúrbios psicológicos e qualidade de vida. MATERIAIS E MÉTODOS: Trinta e dois pacientes com FM e 32 voluntários saudáveis foram incluídos no estudo. Os dois grupos foram comparados em relação à latência e duração do PSC em ambos os membros superiores e inferiores. Características da doença, distúrbios psicológicos e qualidade de vida dos pacientes foram avaliados utilizando o Fibromyalgia Impact Questionnaire (FIQ), e o Short Form-36 (SF-36). Os pacientes com medida de PSC igual ou inferior às do grupo controle foram comparados com aqueles com valores mais elevados do que os controles em termos de características da doença, estado psicológicos e qualidade de vida. RESULTADOS: Latências significativamente prolongadas de PSC nos membros superiores e inferiores foram determinadas em pacientes comparados com os controles. Observou-se que a prolongamento da latência do PSC no membro inferior estava associado com a gravidade da doença e incapacidade funcional. CONCLUSÕES: Latências do PCS nos membros superiores e inferiores em pacientes com FM são mais longas do que em voluntários saudáveis. Além disso, o prolongamento da latência do PSC no membro inferior está associado com a gravidade da doença e incapacidade funcional física.
INTRODUCTION: Cutaneous silent period (CSP) is an inhibitory spinal protective reflex and its afferents consist of A-delta nerve fibers. We aimed to evaluate patients with fibromyalgia (FM) and healthy controls to determine any differences between the groups in terms of CSP duration and latency, and if present, to determine whether there is any relationship with disease characteristics, psychological disorders and quality of life. MATERIALS AND METHODS: Thirty-two patients with FM and 32 healthy volunteers were included in the study. The patient and control groups were compared in terms of CSP latency and duration in both upper and lower extremities. Disease characteristics, psychological disorders and quality of life of patients were assessed using the Fibromyalgia Impact Questionnaire (FIQ) and Short Form-36 (SF-36). Patients with CSP measurements equal to or lower than those of the control group were compared with those with higher values than controls in terms of disease characteristics, psychological status and quality of life. RESULTS: Significantly prolonged CSP latencies in both upper and lower extremities were determined in patients compared to controls. We found that prolongation of CSP latency in the lower extremity is associated with disease severity and functional disability. CONCLUSIONS: CSP latencies in both upper and lower extremities in patients with FM are longer than in healthy volunteers. Moreover, prolongation of CSP latency in the lower extremity is associated with disease severity and physical functional disability.

INTRODUCTION: Cerebral palsy is the most common cause of physical disability in children. Spasticity is a disabling clinical symptom that is prevalent among patients suffering from cerebral palsy. The treatment of spasticity with botulinum toxin type A (BTX-A) is a well-established option in the interdisciplinary management of spasticity, providing focal reductions in muscle tone in cerebral palsy patients. OBJECTIVE: The aim of this retrospective study was to describe the effect of multilevel BTX-A injections in the lower extremities, focusing mainly on gross motor function and functional status in cerebral palsy patients. METHODS: Data from 71 cerebral palsy patients (64 percent male, 36 percent female, mean age 6.7 ±3.2 years) were analyzed retrospectively. We used the Ashworth and Tardieu scales to evaluate the degree of spasticity. Motor function was measured by the Gross Motor Function Measure (GMFM-88), and functional status was classified by the Gross Motor Function Classification System (GMFCS I-V). Multilevel BTX-A injections were applied after sedation and with electrostimulation guidance. The evaluations were repeated every three months, and the patients were followed for six months. RESULTS: We found that the Ashworth and Tardieu scores decreased significantly at the three-month evaluation (p<0.05) but not at the six-month evaluation (p>0.05). Although the improvement in spasticity was not maintained at the six-month evaluation, GMFM-88 scores increased significantly at the three- and six-month assessments. GMFSC levels showed no change in the three- and six-month assessments. CONCLUSION: We believe that a single multilevel BTX-A injection reduces spasticity and improves motor function in children with cerebral palsy.
