Antenatal Pelvic Girdle Pain and Return-to-Work Pressure
A 30-year-old at 28 weeks gestation, a hospital nurse working 12-hour shifts, reports anterior and posterior pelvic girdle pain, 5/10 at rest and 8/10 after shifts, with pain on turning in bed, stairs, and single-leg stance. She has no red flags. On exam: positive provocation tests for the symphysis and both sacroiliac joints, pain with hip abduction against resistance, and a widened stance gait. Her manager is pressuring her to maintain full duties. She wants to work as long as possible and asks whether a support belt will 'fix it.'
1. What is your diagnosis and how do you counsel her on the belt and on work modification?

Diagnosis: pregnancy-related pelvic girdle pain (PGP) with symphyseal and bilateral sacroiliac involvement, functionally limiting at 28 weeks.
Belt counseling: a pelvic support belt can reduce pain during specific tasks (walking, prolonged standing) by adding compression and proprioceptive input, but it is an adjunct, not a cure. It should be fitted correctly, worn for tasks rather than all day, and paired with exercise and load management. Do not let her believe it 'fixes' the underlying load-tolerance problem.
Work modification: with 12-hour shifts and 8/10 end-of-shift pain, full duties are not sustainable. Recommend task modification (reduce prolonged standing, limit repetitive lifting/patient handling, scheduled micro-breaks, seated tasks) and a graded plan. Frame this as preserving her ability to work longer, which aligns with her goal. Document functional limitations to support the employer conversation.
2. Design the core exercise and self-management program and state how you will measure whether it is working.

Program (task-specific, not generic):
- Stability/endurance: pelvic floor and deep hip/trunk coordination with attention to symmetry; avoid painful single-leg loading initially.
- Functional retraining: turning in bed with knees together, sit-to-stand mechanics, stair strategy, and stance width.
- Strength: progressive hip abductor/extensor work within pain tolerance.
- Self-management: pacing, micro-breaks, belt for high-demand tasks, sleep positioning with pillow between knees.
Outcome measures:
- Pain (NRS) at rest and after a shift.
- Function: timed stairs, sit-to-stand, and a validated PGP-specific measure (e.g., Pelvic Girdle Questionnaire).
- Work tolerance: hours/shift completed without escalation of pain.
Decision rule: pain should settle within 24 h of activity; if it escalates and persists, reduce load. Reassess in 2-3 weeks. If pain worsens or new neurologic signs appear, escalate.
