Certified Orthotist and the Wound Team - Taking the pressure off
Treat the Cause – assess and modify situations where pressure may be increased”*
* “Pathway to Assessment/Treatment of Pressure Ulcers” in the RNAO Best Practice Recommendations

Diabetic Autonomic Neuropathy – Nerve Damage
Impairment of sweat glands
Dry feet
Increased dilation of arterioles (excess of blood) and joint/tissue damage
Charcot Foot

Diabetic Autonomic Neuropathy – What can be done?
Skin care
Moisturize
Wear shoes that fit well

Diabetic Motor Neuropathy – Loss of Intrinsic Muscle
Muscle imbalance – “claw foot”
Causes high pressure area at metatarsal
heads, PIP joints and distal tips of toes.
Loss of ankle/foot
dorsiflexors causes “drop foot”

Diabetic Motor Neuropathy – What can be done?
For Muscle Imbalance – Foot Orthoses (FO)
For Drop foot – Ankle Foot Orthosis (AFO)

Sensory Neuropathy – Loss of Protective Sensation
Cannot feel foreign objects in shoes
Not aware to change gait to protect feet
Ill fitting shoes (too tight)

Sensory Neuropathy – What can be done?
Education/Behaviour

Proper shoe fitting

Pressure = Force/area
Pressure is inversely proportional to surface area that force is applied
Force – mass x acceleration – hard to change
Area – can we change the size, shape or contour of the area over which the force is applied?

What can be done to Re-distribute Pressure?
