Tarsal tunnel syndrome (TTS) is a compression neuropathy of the posterior tibial nerve (or one of its branches) as it passes through the tarsal tunnel -- a fibrous canal posterior and inferior to the medial malleolus. It produces pain, burning, tingling, and numbness in the plantar surface of the foot, toes, and heel. TTS is the foot equivalent of carpal tunnel syndrome in the wrist. It is provoked by standing, walking, and prolonged weight-bearing, and relieved by rest and elevation.
How TTS Affects Walking
The posterior tibial nerve controls sensation in the sole of the foot and the intrinsic foot muscles. Tarsal tunnel compression produces:
- Burning and electric-shock pain in the sole and toes, triggered by weight-bearing
- Tingling that increases with walking duration and decreases with rest
- In advanced cases: weakness of toe flexors and intrinsic muscles, reducing push-off power
- Night pain in some patients (nerve inflammation worsening in dependent position)
Cane Use in Tarsal Tunnel Syndrome
A walking cane reduces the weight-bearing load through the affected foot, reducing the compression forces within the tarsal tunnel during gait. This directly reduces the nerve irritation at the compression site. The benefit is most pronounced during the stance phase of gait, when the foot is fully loaded and the tarsal tunnel volume is minimised (hindfoot pronation narrows the tunnel).
TTS Severity and Cane Appropriateness
| TTS Severity | Symptoms | Cane Role |
|---|---|---|
| Mild | Occasional burning; symptoms with prolonged standing only | Cane optional; most useful for long distances or prolonged standing |
| Moderate | Pain with normal walking; reduced walking distance | Cane recommended; contralateral to affected foot; reduces tarsal tunnel compression |
| Severe / chronic | Constant burning; intrinsic weakness; quality of life impairment | Cane beneficial; may also require orthoses, anti-pronation support |
| Post-surgical decompression | Variable; recovery 3-6 months; initial walking discomfort | Cane for 2-4 weeks post-op; reduces foot loading during healing |
Orthotics and the Cane in TTS
Hindfoot pronation narrows the tarsal tunnel and is the most common provocative factor in TTS. Anti-pronation orthotics (medial arch support) are a primary non-surgical treatment. The combination of orthotic (corrects tunnel geometry) and cane (reduces load through the tunnel) provides additive benefit: the orthotic reduces the compressive force per unit of weight-bearing, and the cane reduces the total weight-bearing load. Used together, they allow more comfortable walking than either alone.
