Iatrogenic Insoles - inappropriate proprioceptive insoles dispensed to patient


(2)  Increased Forward Lean

In the above example, the head immediately shifts forward when the incorrect proprioceptive signal is placed under the patient's feet.

  • Proprioceptive Insole designed for a Rothbarts Foot was used on this patient with a PreClinical Clubfoot Deformity

This forward head position increases the strain on the neck muscles, resulting in debilitating headaches.

(3)  Stomach Distension/Protrusion 

(1)  Increased Forward Head Position

In the above example, there is an immediate distension/protrusion (See Arrow B) of the stomach when the incorrect proprioceptive signal is placed under the patient's feet.

  • The proprioceptive signal used was too weak

Abdominal distension (due to the weakness in the abdominal muscles) is frequently linked to GastroIntestinaI Symptoms such as diarrhea, nauseousness, constipation, abdominal pain and/or vomiting (e.g., G.I. Dysfunction).  

If the wrong type of proprioceptive insole is used, it can actually increase the postural distortion, and with it, the patient's subjective symptoms.

Below, a patient was originally fitted with a KS Italia insole to reverse a postural distortion resulting from a severe Rothbarts Foot.  This type insole should never be dispensed to patients with a Rothbarts Foot.

  • Note the increased forward shift in posture (a negative shift). 

When the correct proprioceptive insole was used (e.g., Rothbart's Insole), the forward shift in posture reduced (a positive shift).

In the above example, there is an immediate increase in the forward lean when the incorrect proprioceptive signal is placed under the patient's feet.

  • The proprioceptive signal used was too strong

The anterior lean increases the load and asymmetrical positioning of the weight bearing joints.  This results in uneven cartilaginous wear patterns withing the joints (much like a car with an alignment problem - resulting in the tires wearing unevenly).
Anterior lean patterns frequently are linked to chronic joint pain (ankle, knee, hip, back and/or jaw).
