Electromyographic activity, pain, disability, and improvement perception in chronic neck pain after multimodal physiotherapy ; Actividad electromiográfica, dolor, discapacidad y percepción de mejoría en dolor cervical crónico en fisioterapia multimodal ; Atividade eletromiográfica, dor, incapacidade e perceção de melhoria na cervicalgia crónica após fisioterapia multimodal

Introduction: Few studies have explored the clinical course in patients with chronic neck pain. Understanding the clinical course can help clinicians evaluate individual patient outcomes, define goals, and establish prognosis. Objective: To describe the clinical course of patients with non-specific chronic neck pain (NCNP) in response to a multimodal physiotherapy program. Methodology: A total of 15 patients with NCNP participated in a six-week physiotherapy multimodal program. Baseline assessments included sociodemographic characteristics and clinical history of neck pain. The main outcome measures were cervical muscle activity, pain, disability, and global perception of improvement. The Friedman and post-hoc tests with Bonferroni correction were used for statistical analysis. Results: All variables under study varied significantly (p<0.001) over the six-week physiotherapy multimodal program. In the first 3 weeks, sternocleidomastoid and anterior scalene muscles showed a significant decrease in muscle activity of 64% and 24%, respectively. All self-reported variables were also observed early significant clinical improvements, with pain and disability decreasing by 50% and 24% at the end of the 3-week intervention. Discussion: Patients with NCNP who are treated with a physiotherapy multimodal program that includes specific motor control exercises can expect a short-term influence on the muscular activity of superficial neck muscles and a reduction of symptoms. Physiotherapists may use this information to make more informed decisions when treating patients with NCNP. Conclusions: The results of the present study may be useful in designing clinical trials to establish whether the improvements were due to the treatment provided or natural condition recovery. ; Introducción: Pocos estudios han explorado el curso clínico en pacientes con dolor cervical crónico. Comprender su evolución clínica puede ayudar a los clínicos a evaluar los resultados individuales, definir objetivos y establecer un pronóstico. Objetivo: ...
