ABSTRACT Objective: To investigate the effectiveness of a home-based therapeutic exercise program on lower back pain and functionality of SCD patients. Setting: A Hematology and Transfusion Medicine Center, University of Campinas (HEMOCENTRO-UNICAMP). Methods: This was a prospective study, with a three-month follow-up of SCD patients with lower back pain. The lumbar spine functionality was evaluated by questionnaires, trunk flexion and extension analyses by fiber-optic-electrogoniometry and measurements of muscle strength of trunk flexor and extensors. The Intervention Group (IG) comprised 18 volunteers, median age 44y (28–58) and the control group (CG) comprised 15 volunteers, median age 42y (19–58), who did not perform exercises. The protocol consisted of daily home-based exercises with two evaluations: at the beginning and end of a three-month program. In order to compare the groups at baseline, the Fishers´ exact test and Mann–Whitney test were used for categorical and numeric variables, respectively. The Wilcoxon test was used for related samples comparing numeric measures of each group over time with a 5% (p < 0.05) significance level. Results: After the intervention, patients demonstrated a significant improvement, according to the Visual-Analog-Scale (VAS; p = 0.01), Rolland Morris Disability questionnaire (RMDQ; p < 0.01) and trunk flexion and extension muscle strength (p < 0.01). No significant differences were found for the Start-Back-Screening-Tool-Brazil (SBST) and in measures of trunk flexion and extension range-of-motion (RoM). Conclusion: Results suggest that daily home-based exercises for a three-month period ameliorate pain and improve disability related to lower back pain and muscle strength.

OBJETIVO: Avaliar o efeito da estimulação elétrica neuromuscular na espasticidade nos pacientes com lesão medular. MÉTODOS: Participaram do estudo onze sujeitos lesados medulares (C4 a T5). Foram utilizados para esta avaliação a escala modificada de Ashworth e o teste pendular, que foi realizado através do Dispositivo de Teste Pendular - DTP (o equipamento possui um acelerômetro de transdutores de cristais de quartzo e eletrogoniômetro de fibra óptica flexível que mede as tensões e os deslocamentos angulares). Os pacientes realizaram estimulação elétrica neuromuscular (EENM) nos músculos quadríceps e nervo fibular, sendo que os testes foram aplicados antes e após o procedimento. RESULTADOS: Os dados mostram uma diminuição da espasticidade após a EENM, com características tais como um aumento na variação entre o pico máximo e o mínimo, ou seja, aumento da amplitude das curvas. Além disso, os dados da escala subjetiva, e escala modificada de Ashworth, após a estimulação elétrica neuromuscular também apresentaram uma redução nos valores da espasticidade. CONCLUSÃO: Os dados sugerem que a EENM é eficaz para reduzir a espasticidade imediatamente após a sua realização.

OBJECTIVE: To evaluate the effect of neuromuscular electrical stimulation on spasticity in patients with spinal cord injury. METHODS: The study included eleven subjects with spinal cord injuries (C4 to T5). The modified Ashworth scale and pendulum test, which is accomplished through the Pendular Test Device - PTD (equipment which has a quartz crystal transducer accelerometer and optic fiber flexible electrogoniometer measuring the tensions and angular displacements). Patients underwent neuromuscular electrical stimulation (NMES) to the quadriceps muscle from fibular nerve, and the tests were administered before and after therapy. RESULTS: The data show a decrease in spasticity after NMES, with features such as increasead variation between maximum and minimum peaks, i.e. increased amplitude of the curves. Furthermore, data from the subjective scale, and modified Ashworth scale after neuromuscular electrical stimulation also showed a reduction in the values of spasticity. CONCLUSION: The data suggest that NMES is effective in reducing spasticity immediately after completion. Level of Evidence II, Therapeutic Studies-Investigating the Results of Treatment.
