Office workers suffer from posture disorders and immobility that can adversely affect spinal health.
Objectives
This study aimed to evaluate the impact of online Transtheoretical Model Based (TTM-based) ergonomic training on regular exercise and correct working posture in office workers.
Methods
This randomized controlled trial (RCT), conducted between 2022-2023 with 130 office workers from Suleyman Demirel University/Türkiye, lasted 24 weeks, including 12 weeks of intervention and 12 weeks of follow-up. Participants were divided into two groups: 66 in the training group and 64 in the control group. All participants were given brochures and exercise visuals at the beginning of the study and regular communication was maintained throughout the intervention period. In addition, during the intervention period, those in the training group received 6 sessions of stage matched training. SPA (Spine Protection Approach) scales, exercise forms, ROSA (Rapid Office Strain Assessment) and CMDQ (Cornell Musculoskeletal Discomfort Questionnaire) were used for assessment.
Results
In the post-test measurements, statistically significant differences were obtained between the groups in stages of change (p < 0.005), decision-making balance (p < 0.05), change process (p < 0.005) and self-efficacy (p < 0.05) related to SPA. In addition, in ROSA score (p < 0.005) and regional risk scores, differences were obtained for upper back (p < 0.005), lower back (p < 0.05), shoulder (p = 0.005), upper arm (p = 0.005) and forearm (p < 0.005), while the number of painful regions did not change (p > 0.05).
Conclusion
The results support that TTM-based training can promote regular exercise and correct working postures and reduce pain-related complaints.
