Polymyalgia rheumatica (PMR) is an inflammatory condition causing pain and stiffness in the shoulder girdle, hip girdle, and neck, typically occurring in people over 50 (mean onset age 70). Despite its name suggesting muscle pain, the primary pathology is synovitis of the large joints (glenohumeral, sternoclavicular, hip) and periarticular bursitis. PMR is closely associated with giant cell arteritis (GCA) and responds dramatically to corticosteroid treatment.
How PMR Affects Walking
PMR characteristically causes morning stiffness lasting more than 45 minutes. During the morning stiffness phase, the patient may be unable to rise from bed or a chair without assistance, and walking is painful and limited. The hip girdle involvement produces pain and stiffness at the hips and proximal thighs during weight-bearing, particularly during the first steps of the day. As the day progresses and corticosteroids take effect, function often improves substantially.
PMR and the Cane: Morning vs. Afternoon Use
The temporal pattern of PMR creates an unusual cane use pattern: the cane may be needed intensively in the morning (during peak stiffness) but not at all by mid-afternoon (once stiffness has resolved). This is different from most cane use scenarios where need is consistent throughout the day. The cane should be positioned at the bedside and in the bathroom to support the critical transition from supine to standing and the first steps of the day.
PMR Clinical Features and Cane Implications
| Feature | Implication for Cane Use |
|---|---|
| Morning stiffness more than 45 minutes | Cane essential in the morning; may not be needed by midday |
| Bilateral hip girdle involvement | Both sides affected; cane may not have a clear contralateral preference; bilateral canes or rollator considered if severe |
| Shoulder pain and stiffness | Shoulder involvement may limit ability to grip and load a cane; assess grip and shoulder range before recommending |
| Dramatic response to prednisolone | Cane need often resolves rapidly with corticosteroids; reassess need at each treatment review |
| Long-term steroid use | Steroid-induced osteoporosis increases fracture risk; cane role extends to fall prevention even after PMR resolution |
Steroid-Induced Osteoporosis and Cane Use
PMR treatment typically requires 1-2 years of corticosteroid therapy. Long-term corticosteroid use causes osteoporosis (vertebral and hip fracture risk increases 2-5x with more than 3 months of use). A cane provides fall prevention during this period of elevated fracture risk, even after the PMR itself has resolved. Patients on long-term steroids for PMR should receive bone protection (bisphosphonates, calcium, vitamin D) and should continue cane use for fall prevention beyond the PMR symptom period.
