Sjögren syndrome (SS) is a systemic autoimmune disease primarily affecting exocrine glands (lacrimal and salivary glands), producing dry eyes and dry mouth, but with significant extraglandular manifestations including peripheral neuropathy, inflammatory arthritis, fatigue, and in severe cases CNS involvement. The walking limitations in Sjögren syndrome are heterogeneous, arising from different disease mechanisms that may coexist in the same patient.
Sjögren Syndrome Features Affecting Walking
- Peripheral neuropathy: Sjögren syndrome causes several distinct peripheral neuropathy patterns -- sensory ataxic neuropathy (ganglionopathy), painful small fibre neuropathy, and motor neuropathy. The sensory ataxic ganglionopathy is particularly disabling: loss of large fibre sensory function causes profound proprioceptive ataxia similar to subacute combined degeneration, with Romberg-positive gait and severe instability in darkness
- Inflammatory arthritis: Articular involvement is similar to rheumatoid arthritis -- peripheral joint pain and swelling limiting walking
- Fatigue: A prominent and often underestimated symptom in Sjögren syndrome, partly from chronic inflammation and partly from autonomic dysfunction. Fatigue limits walking distance independently of joint or neuropathic symptoms
- Autonomic neuropathy: Small fibre autonomic involvement causes orthostatic hypotension and POTS, adding the orthostatic fall risk to the neuropathic gait problem
Sensory Ataxic Neuropathy in Sjögren: The Most Serious Walking Limitation
The ganglionopathy (dorsal root ganglion involvement) of Sjögren syndrome destroys large sensory neurones, causing irreversible proprioceptive loss. Unlike inflammatory neuropathies that may recover with immunotherapy, ganglionopathy in SS often produces permanent sensory loss. Walking aid needs may therefore be long-term.
Cane Use in Sjögren Syndrome
| SS Feature | Walking Impact | Cane Role |
|---|---|---|
| Sensory ataxic neuropathy (ganglionopathy) | Romberg-positive; severe instability in darkness; proprioceptive loss | Essential sensory substitution; primary ground reference in low light |
| Painful small fibre neuropathy | Foot burning/pain with walking; reduced tolerance | Ipsilateral cane reduces foot loading; pain management primary |
| Inflammatory arthritis | Joint pain; swelling; reduced range of motion | Contralateral cane for most affected joint; as per RA protocol |
| Fatigue | Rapid walking fatigue; reduced daily walking distance | Reduces postural demand; extends walking tolerance |
| Autonomic neuropathy / POTS | Orthostatic symptoms on standing | Immediate support on rising; lean support during prolonged standing |
