Effects of Glute Activation Exercises on Low Back Pain in Office Workers with Gluteal Amnesia: Case Study

Abstract

Background: Low back pain is highly common among office workers because prolonged sitting, low physical activity, poor lumbopelvic control, and repetitive static postures place sustained mechanical demand on the lumbar spine. Gluteal amnesia refers to delayed, reduced, or poorly coordinated activation of the gluteus maximus and gluteus medius during hip extension, pelvic stabilization, gait, squatting, stair climbing, and sit-to-stand activity. When the gluteal muscles fail to contribute efficiently, the lumbar extensors, hamstrings, tensor fascia lata, and hip flexors may compensate, leading to increased lumbar loading, anterior pelvic tilt, altered hip mechanics, and recurrent pain. Glute activation exercises are used to restore neuromuscular awareness, improve hip extension strategy, enhance pelvic control, and reduce unnecessary lumbar overuse during functional movement.

Presentation of Cases: This case study presents two adult office workers with mechanical low back pain and clinical features consistent with gluteal amnesia. Both worked more than seven hours daily in sitting, reported repeated episodes of pain after prolonged computer work, and demonstrated weak or delayed glute activation during prone hip extension, bridge holding, single-leg support, and sit-to- stand assessment. Case A presented with dominant gluteus maximus inhibition, hamstring overactivity, and extension-related lumbar discomfort. Case B presented with gluteus medius weakness, pelvic drop, dynamic knee valgus, and pain during stairs and prolonged standing. Both cases were medically stable and participated in a six-week supervised physiotherapy programme with progressive home practice.

Intervention: The intervention included education regarding sitting breaks and neutral spine awareness, low-load glute setting, supine bridge progression, prone hip extension with abdominal bracing, clamshells, side-lying hip abduction, band-resisted lateral walk, quadruped hip extension, hip hinge training, sit-to-stand retraining, step-up control, and work-related movement practice. Exercise intensity was progressed according to pain response, quality of activation, endurance, and ability to avoid lumbar substitution. Both cases were monitored for symptom irritability and fatigue.

Outcome Measures: Pain intensity, disability, strength, activation timing, movement control, and work tolerance were documented using the Numeric Pain Rating Scale, Oswestry Disability Index, manual muscle testing of gluteus maximus and medius, prone hip extension observation, single-leg bridge endurance, Trendelenburg assessment, sit-to-stand quality, sitting tolerance record, and a therapist-maintained functional task log.

Results: At six weeks both office workers showed reduction in pain, improvement in gluteal strength, better pelvic control, and increased tolerance for sitting and daily activity. Case A improved markedly in hip extension pattern, bridge endurance, and reduction of lumbar extensor dominance. Case B showed stronger improvement in frontal-plane pelvic stability, stair confidence, and single- leg control. Pain decreased from moderate-severe to mild levels in both cases, and disability shifted from moderate limitation to minimal functional restriction. The greatest functional changes were noted in prolonged sitting, rising from a chair, walking after office hours, stair use, and confidence during household activity.

Conclusion: Glute activation exercises were associated with meaningful improvement in low back pain, hip muscle performance, and functional tolerance in office workers with gluteal amnesia. The findings support a progressive programme that begins with isolated neuromuscular activation and advances toward task-based hip control.
