Brief Summary:
Implementing workplace strategies to manage symptoms in office workers with chronic nonspecific spinal pain (CNSP) may improve both health- and work-related outcomes, as adherence to these interventions is more feasible in this context. Exercise therapy is considered the first-line treatment for CNSP; however, the added value of combining exercise therapy with manual therapy remains inconclusive. This study aims to examine the effects of short sessions of exercise therapy plus manual therapy, compared with exercise therapy plus sham manual therapy, delivered in the workplace, on health- and work-related outcomes in office workers with CNSP.
Detailed Description:
Objectives: To evaluate the effects of short sessions of exercise therapy plus manual therapy compared with exercise therapy plus sham manual therapy at work on self-perceived productivity, disability, global impression of change, pain intensity, depression, anxiety, and muscle tone.
Methods: A randomized controlled trial will be conducted. The study protocol was approved by the Research Ethics Committee of Catholic University of Murcia (UCAM) (CE042403). Eligible participants will be office workers from the UCAM University with nonspecific spinal pain. Participants will be randomized into two groups. The experimental group will receive exercise therapy plus manual therapy, while the control group will receive exercise therapy plus sham manual therapy. Both groups will complete two 15-minute sessions of exercise therapy per week for 8 weeks. In addition, the experimental group will receive two 15-minute sessions of manual therapy per week, while the control group will receive sham manual therapy during the same period.
Outcomes: The primary outcomes will be self-perceived productivity, disability, patient global impression of change, and pain intensity. Secondary outcomes will include depression, anxiety, and muscle tone. Assessments will be conducted at baseline, post-intervention, and at 3- and 6-month follow-ups. Any possible adverse events will be registered during the 8-weeks of interventions.
Sample Size Estimation: Sample size was calculated using G\*Power 3.1. To detect differences between groups over time, a small effect size (f = 0.17) was assumed, with 80% power and a 5% alpha level, indicating a minimum of 50 participants. Allowing for a 20% dropout rate, the target sample size was set at 60 participants (30 per group).
Statistical Analysis: A repeated-measures ANOVA (time × group) will be used. Mauchly's test will assess sphericity; if violated, the Greenhouse-Geisser correction will be applied. Post-hoc pairwise comparisons will be adjusted using Bonferroni correction. Effect sizes will be reported as partial eta-squared, and Cohen's d will be used for post-hoc comparisons. A chi-square test will assess the effectiveness of blinding by evaluating participants' perceptions of the intervention.
