Q

What pathologies can occur from Deep Shear Stress?

A

Bursas/Bursitis

‘Glassicallus’

17
Q

What is Compressional Stress?

A

When the forces are being pulled together

18
Q

What Pathologies occur as a result of tensile stress?

A

Fissures - cracks in the skin - occurs often interdigitally, and around the calcaneous

19
Q

What is Torsional Stress?

A

An amalgamation of shearing, tensile and compressional stress, it can occur when the foot is used in a pivotal action

20
Q

What pathologies can occur from Torsional Stress, and at what common areas?

A

Callus

Common areas:

  1. Plantar aspect of 1st mtpj
  2. Plantar calcaneal area
  3. Plantar aspect of hallux
