Chronic kidney disease (CKD) is defined as kidney damage or reduced kidney function (GFR below 60 mL/min/1.73m2) persisting for more than 3 months. As CKD progresses toward end-stage kidney disease (ESKD) and dialysis, its systemic effects on walking capacity become substantial and multi-layered.
How CKD Affects Walking
- Uraemic myopathy: Accumulation of uraemic toxins causes skeletal muscle dysfunction and atrophy. Proximal muscle weakness (similar in distribution to steroid myopathy) is common in advanced CKD and ESKD. Quadriceps weakness is particularly relevant for walking
- Uraemic neuropathy: The peripheral nervous system is affected by uraemia, causing a length-dependent sensorimotor neuropathy similar to diabetic peripheral neuropathy. Sensory loss in the feet impairs proprioception and balance; motor weakness causes gait abnormality
- Anaemia: Erythropoietin deficiency in CKD causes anaemia. Reduced haemoglobin lowers oxygen-carrying capacity, limiting exercise tolerance and walking endurance
- Cardiovascular complications: CKD strongly promotes cardiovascular disease. Heart failure, coronary disease, and peripheral arterial disease (all more common in CKD) further limit walking capacity
- CKD-MBD (mineral and bone disorder): Disturbed calcium, phosphate, PTH, and vitamin D metabolism causes secondary hyperparathyroidism, renal osteodystrophy, and osteoporosis -- increasing fracture risk during walking falls
Dialysis and Walking
Haemodialysis (typically 3 times weekly, 4 hours per session) creates a specific walking pattern:
- Post-dialysis fatigue: many patients are exhausted for hours after dialysis sessions. Walking capacity on dialysis days is significantly lower than on non-dialysis days
- Intradialytic hypotension: blood pressure drops during dialysis are common and can persist into the post-dialysis period, creating orthostatic hypotension risk when standing to walk
- A walking cane on dialysis days -- particularly in the hours immediately after a session -- is more necessary than on non-dialysis days
Walking Cane Role in CKD and ESKD
- Uraemic neuropathy: proprioceptive supplement, fall prevention, same role as for any peripheral neuropathy
- Uraemic myopathy: compensate proximal weakness during walking, stability during stance phase
- Post-dialysis fatigue and hypotension: transition anchor for sit-to-stand, energy economy
- Renal osteodystrophy/osteoporosis: fall prevention is especially important given higher fracture risk from bone disease
CKD Stage and Walking Aid Relevance
| CKD Stage | Primary Walking Impact | Cane Role |
|---|---|---|
| CKD G3 (GFR 30-59) | Mild fatigue and early neuropathy | Optional; terrain safety; fall prevention if neuropathy |
| CKD G4 (GFR 15-29) | Significant fatigue, neuropathy, anaemia | Consistent use recommended; energy economy |
| CKD G5/ESKD (GFR <15 / dialysis) | Severe; post-dialysis particularly limited | Essential on dialysis days; used throughout |
