Resumo(s)
Enquadramento: A Lombalgia crónica é considerada a principal causa de anos vividos com
incapacidade em todo o mundo. A evidência disponível demonstra que o exercício físico
apresenta uma tendência para a redução da dor. No entanto, a variabilidade de modalidades de
exercício disponíveis e a utilização de programas pobremente descritos não permitem formular
recomendações claras para a prática clínica. Por outro lado, parecem exisitir outros efeitos
induzidos pelo exercício, de cariz psicossocial, que parecem ter um papel mais preponderante na
alteração dos níveis de dor e funcionalidade ao invés da exclusiva melhoria da capacidade física
dos indivíduos. Objetivo: Pretende-se comparar dois programas de exercício estruturado (força
de resistência vs aeróbio) em indivíduos com lombalgia crónica não específica ao nível da
intensidade da dor, catastrofização e qualidade de vida. Metodologia: Foi conduzido um estudo
piloto randomizado, de duração de 12 semanas, que incluiu 13 indivíduos com lombalgia crónica.
O grupo de controlo (n=8) realizou um programa de exercício de força de resistência
previamente testado (programa Rehmove), enquanto que o grupo experimental (n=5) realizou
um protocolo de exercício aeróbio criado para o efeito. Os participantes foram avaliados antes da
intervenção (baseline), às 6 e às 12 semanas. Foram utilizados os instrumentos: Escala
Numérica da Dor (END); Pain Catastrophizing Scale (PCS); EQ-5D-3L (Qualidade de Vida
relacionada com a Saúde); Escala de Atividade Física Habitual Modificada (EAFHM); e Global
Perceived Effect Scale (GPES). Foi utilizada a StarT Back Screening Tool (SBST) na baseline
para averiguar o risco de desenvolver dor persistente. Resultados: Não existiram diferenças
estatisticamente significativas intergrupo. A análise intragrupos demonstrou diferenças
estatisticamente significativas a favor do grupo de controlo ao nível da intensidade da dor e
qualidade de vida relacionada com a saúde. Conclusão: Os resultados mostram que, quando
comparadas entre si, não parece existir uma modalidade de exercício mais eficaz gestão da
lombalgia crónica. Parece existir uma melhoria mais rápida (às 6 semanas) ao nível dos
outcomes intensidade da dor e qualidade de vida relacionada com a saúde perante a realização
de um programa de exercícios de força de resistência. No entanto, é necessária a realização de
estudos de maior qualidade e dimensão para verificar a reprodutibilidade dos resultados obtidos.
Chronic Low Back Pain (LBP) is considered the leading cause of years lived with disability worldwide. The available evidence demonstrates that physical exercise has a tendency to reduce pain. However, the variability of exercise modalities available and the use of poorly described programs do not allow us to formulate clear recommendations for clinical practice. On the other hand, there seem to be other effects induced by exercise, of a psychosocial nature, which seem to have a more preponderant role in altering pain levels and functionality rather than in the exclusive improvement of individuals' physical capacity. Objective: To compare two structured exercise programs (resistance vs aerobic) in individuals with chronic non-specific low back pain in terms of pain intensity, catastrophizing and quality of life. Methodology: A 12-week randomized pilot study was conducted, including 13 subjects with chronic low back pain. The control group (n=8) performed a previously tested resistance strength exercise program (Rehmove program), while the experimental group (n=5) performed an aerobic exercise protocol created for this purpose. Participants were assessed before the intervention (baseline), at 6 and 12 weeks. The following instruments were used: Numerical Pain Scale (END); Pain Catastrophizing Scale (PCS); EQ-5D-3L (Health-Related Quality of Life); Modified Habitual Physical Activity Scale (EAFHM); and Global Perceived Effect Scale (GPES). The StarT Back Screening Tool (SBST) was used at baseline to assess the risk of developing persistent pain. Results: There were no statistically significant differences between groups. The intragroup analysis showed statistically significant differences in favor of the control group in terms of pain intensity and health-related quality of life. Conclusion: The results show that, when compared to each other, there does not seem to be a more effective exercise modality for chronic low back pain management. There appears to be a faster improvement (at 6 weeks) in the outcomes of pain intensity and health-related quality of life outcomes when performing an resistance exercise program. However, it is necessary to carry out studies of greater quality and dimension to verify the reproducibility of the results obtained.
