Comparative Analysis of Manual Therapy and Exercise for Chronic Neck Pain Relief

Thesis Abstract

Chronic neck pain remains a prevalent musculoskeletal disorder that impairs functional capacity and diminishes quality of life, yet optimal intervention strategies continue to be debated among clinicians and researchers. This study aims to comparatively analyze the effectiveness of manual therapy and exercise interventions in relieving chronic neck pain, with a specific focus on assessing their short-term and medium-term outcomes. It seeks to identify which intervention produces superior pain reduction, functional improvement, and patient satisfaction, thereby informing clinical practice guidelines. Employing a randomized controlled trial design, the study recruited 150 adult participants aged 25 to 55 years diagnosed with nonspecific chronic neck pain lasting longer than three months. Participants were randomly assigned to three groups manual therapy, exercise therapy, and a control group receiving placebo treatment. Data collection involved standardized instruments including the Visual Analog Scale (VAS) for pain severity, the Neck Disability Index (NDI) for functional impairment, and the Global Perceived Effect (GPE) scale for patient satisfaction. Baseline assessments were conducted prior to intervention, with follow-up evaluations at four weeks (post-intervention) and three months (medium-term follow-up). The intervention period spanned six sessions over four weeks, tailored according to protocols delineated by the American Physical Therapy Association for manual therapy and exercise prescription. Data analysis employed descriptive statistics to summarize participant characteristics and outcome measures. Inferential analysis was conducted using repeated-measures ANOVA to compare within-group changes over time and between-group differences across time points. Post-hoc testing with Bonferroni correction determined the significance of pairwise comparisons. Additionally, regression analyses explored the relationship between baseline variables and treatment outcomes, controlling for confounders such as age, gender, and duration of neck pain. The theoretical framework draws upon the Biopsychosocial Model of Pain and Melzack and Wall’s Gate Control Theory, integrating the physiological and psychological dimensions of pain and therapeutic response. Expected findings indicate significant improvements in pain reduction and functional capacity in both manual therapy and exercise groups compared to the control group, with manual therapy potentially yielding more immediate pain relief. Medium-term assessments are anticipated to reveal sustained benefits, with exercise therapy possibly showing greater enhancement in long-term functional adaptation. Subgroup analyses may identify demographic or psychosocial factors influencing treatment efficacy. This comparative analysis contributes to the extant body of knowledge by delineating differential impacts of manual and exercise therapies in chronic neck pain management, providing empirical evidence to guide clinical decision-making. The main conclusion posits that both manual therapy and exercise are effective interventions, with specific advantages in different outcome domains and time frames. Recommendations include integrating tailored manual therapy and exercise programs within multidisciplinary treatment models for chronic neck pain and emphasizing patient-centered approaches based on individual responsiveness. The study advocates for further research employing larger sample sizes, longer follow-up periods, and exploration of combined therapy modalities to optimize treatment outcomes. Overall, this research enhances understanding of therapy-specific mechanisms and offers actionable insights to improve symptom management, functional recovery, and quality of life for individuals suffering from chronic neck pain.
