Psoriatic arthritis (PsA) is an inflammatory arthritis occurring in approximately 30% of people with psoriasis. It is a heterogeneous condition: some patients have predominantly finger and toe joint involvement (DIP pattern), others have large joint inflammation (hip, knee, ankle), others have axial (spine and sacroiliac) involvement, and many have enthesitis and dactylitis. For walking cane guidance, the critical pattern is lower limb PsA -- particularly knee, ankle, foot, and enthesitis involvement.
Lower Limb PsA Features That Affect Walking
- Knee arthritis: Effusion and synovitis produce pain, warmth, and reduced range of motion; significant impact on weight-bearing and stair use
- Ankle arthritis: Tibiotalar synovitis; pain with dorsiflexion (heel strike) and push-off; may coexist with Achilles enthesitis
- Foot involvement: Subtalar arthritis, MTP joint inflammation, dactylitis of toes -- all reduce push-off and weight distribution
- Enthesitis: Achilles tendon insertion and plantar fascia enthesitis; produces heel pain characteristic of PsA; pain worst in the morning and at heel strike
- Axial PsA: Spine involvement reduces trunk rotation and lateral flexion; less direct gait effect but can produce antalgic gait pattern
PsA Pattern and Cane Role
| PsA Pattern | Primary Gait Problem | Cane Role |
|---|---|---|
| Knee arthritis (unilateral) | Weight-bearing pain; stair difficulty; antalgic limp | Contralateral cane; significant load reduction at knee |
| Ankle / subtalar arthritis | Heel strike pain; reduced push-off | Contralateral cane; midfoot strike technique to reduce enthesitis load |
| Enthesitis (Achilles, plantar fascia) | Heel pain; worst in morning, at first steps | Cane for morning walking; reduces heel strike force |
| Foot dactylitis (sausage toes) | Foot pain with weight-bearing; forefoot overload | Cane reduces overall foot loading; combine with cushioned footwear |
| Mutilans (severe joint destruction) | Significant instability; severe deformity | Cane may be insufficient; rollator or forearm crutches considered |
Biologic Therapy and Cane Use
The introduction of biologic therapies (TNF inhibitors, IL-17 inhibitors, IL-23 inhibitors) and targeted synthetic DMARDs (JAK inhibitors) has transformed PsA management. Many patients achieve low disease activity or remission with effective treatment. Cane use in well-controlled PsA should be reassessed as disease activity improves: a cane appropriate during a flare may not be needed during remission. Equally, inadequate disease control means the cane remains a daily necessity.
Psoriasis and Cane Handle Hygiene
Patients with active psoriasis, particularly of the hands, may have skin fragility, fissuring, and infection risk at the cane handle contact area. A smooth, non-porous handle (finished wood or polymer) is preferable to foam or rubber that can harbour bacteria in skin fissures. The DaiWalk solid wood handle can be wiped clean without degradation, which matters for patients managing psoriatic skin disease of the hands.
