Chronic kidney disease (CKD) is a progressive loss of kidney function affecting approximately 10-15% of adults globally. From a mobility perspective, CKD creates multiple concurrent problems: renal anaemia causing profound fatigue, peripheral neuropathy (uraemic neuropathy), renal bone disease (CKD-MBD causing bone fragility and skeletal deformity), and cardiovascular disease limiting exercise tolerance. Many CKD patients reach dialysis with significant mobility limitation before kidney failure itself is the most pressing problem.
CKD Features Affecting Walking
| CKD Feature | Prevalence in CKD | Walking Impact | Cane Role |
|---|---|---|---|
| Renal anaemia | Near universal in CKD stages 3b-5 | Fatigue; reduced exercise tolerance; dyspnoea on exertion | Cane reduces walking metabolic demand; extends functional walking distance |
| Uraemic peripheral neuropathy | Up to 65% in end-stage renal disease | Sensory loss; imbalance; restless legs | Cane compensates for sensory ataxia; reduces fall risk |
| Renal osteodystrophy (CKD-MBD) | Nearly all CKD stage 3+ patients | Bone pain; fracture risk; skeletal deformity | Cane for pain reduction; fall prevention in high fracture-risk patients |
| Dialysis-related fatigue | Post-dialysis fatigue in up to 70% of HD patients | Extreme fatigue for hours post-dialysis; limited mobility on dialysis days | Cane essential on dialysis days; potentially not needed on non-dialysis days |
| Cardiovascular disease | Leading cause of death in CKD | Exercise intolerance; claudication if PAD present | Cane allows rest-break positioning; reduces cardiovascular demand of walking |
Dialysis Patients: Cane on Dialysis Days vs. Non-Dialysis Days
Haemodialysis (HD) sessions are profoundly fatiguing. Approximately 70% of HD patients report significant post-dialysis fatigue that can last 4-6 hours after each session. Cane need may be significantly greater on dialysis days than on days between sessions. Planning cane use around the dialysis schedule -- always having the cane on dialysis days, with optional use on other days -- is a practical strategy many patients benefit from.
Uraemic Neuropathy and the Cane
Uraemic neuropathy is a predominantly sensory and motor neuropathy affecting the distal lower limbs (length-dependent: feet affected first). Sensory loss in the feet removes the proprioceptive input that normally contributes 50-60% of upright balance. A cane provides additional contact with the ground, giving the nervous system an alternative balance signal through the upper limb. Restless legs syndrome (extremely common in CKD, particularly in dialysis patients) does not directly impair walking mechanics but significantly disrupts sleep, contributing to daytime fatigue and fall risk.
