Understanding the Coleman Block Test Assessment
To assess the **flexibility of a hindfoot varus deformity** and determine if it is fixed (bony) or flexible (soft tissue) in a patient with a **Cavus Foot (High Arch)**.
Watch How It's Done
How do I start?
Patient is standing with the lateral border of the foot elevated on a 1-inch wooden block, leaving the heel and first metatarsal head free.
What happens?
The patient shifts weight onto the block. The block allows the forefoot to plantarflex, which *removes the influence of the forefoot on the hindfoot*.
In Plain English
What Does a Positive Result Mean?
If the **hindfoot varus corrects or reduces** to neutral when standing on the block, the deformity is considered **flexible** (due to soft tissue/muscles). If it **does not correct**, the deformity is considered **fixed** (bony).
Helpful Tip:
This test helps determine the optimal surgical or orthotic intervention for a high arch foot.
Safety First
This guide is to help you understand what happens in a clinic. Do not try to diagnose yourself. If you have severe pain, swelling, or cannot put weight on your leg, please visit an urgent care center or your doctor immediately.
Other Foot Tests
External Rotation Stress Test (Syndesmosis Ligament Test)
To assess the integrity of the **Distal Tibiofibular Syndesmosis** (high ankle sprain ligaments) by applying a rotational stress.
Feiss Line Test (or Feiss Line Grading)
To clinically assess and grade the degree of **longitudinal arch collapse (Pes Planus or Flat Foot)**.
Navicular Drop Test (or Staheli's Arch Index)
To quantify the change in height of the **medial longitudinal arch** from non-weight bearing to full weight bearing (assessing flexible flatfoot).
Toe Spread Test
To assess the **strength and endurance of the intrinsic foot muscles** (IFMs), which are essential for arch stabilization and dynamic balance.
