‘Ergonomics Adjustments For Chronic Mechanical Low Back Pain Patient’: A Case Study

Background: Ergonomics aims to optimize work environments to align with individual physical capabilities, particularly in healthcare settings where chronic low back pain is prevalent among professionals like dentists. This study investigates the effects of ergonomic adjustments combined with conventional physiotherapy on a 30- year-old female dentist suffering from chronic low back pain. Method: The patient underwent an initial treatment phase focusing on stretching and strengthening exercises, followed by a three-week period of ergonomic interventions targeting her workplace environment. Pain intensity, functional status, and quality of life were assessed using the Numerical Pain Rating Scale, Oswestry Disability Index, and WHOQOL-BREF questionnaire. Results: After four weeks, the patient's pain intensity decreased from 7/10 to 3/10, and her functional status improved from 44% (severe disability) to 16% (mild disability). Significant enhancements in physical health and environmental perceptions were noted, with WHOQOL-BREF scores indicating improved overall wellbeing. Conclusion: The integration of ergonomic adjustments with physiotherapy significantly alleviated pain and improved functional capacity and quality of life for the patient, highlighting the importance of ergonomic principles in managing chronic low back pain in physically demanding professions
