2? applied second

Wear both tapes for first 3?

then remove 4 remaining

A
  1. Fat Pad compression taping
  2. 3 way modified low dye
  3. 24 hrs
25
Q

Fat Pad Atrophy

Determine if any difference between taping, if more 1? involvement, the 2? will feel

better. Can guide orthotic prescription.

A
  1. fat pad
  2. fat pad compression taping
26

  1. Footwear
  2. Orthotics
  3. Surgical
  4. Controversial:
A
  1. Ensure excellent cushioning in footwear
  2. Prescribe a deep heel cup to cushion the fat

pad, preventing spread. Can also use a heel aperture

filled with poron to provide additional cushioning

  1. Autolipotransplantation, involving harvested

adipose tissue from calf

  1. liquid silicone injections
27
Q

Foot kinematics

Those with plantar heel pain have 1? postulated to increase loads on PF.

A

greater total rearfoot eversion and peak PMPj DF

28
Q

the functional risk factors for Plantar fascia:

Prolonged foot pronation causes 1?

Muscles that may be involved with increased pronation are

2? caused by weakness reducing ability to pronate or resupinate the foot.

Proximal muscles that may be involved 3?

Intrinsic foot musculature

A
  1. muscle weakness, achilles tightness, structural foot deformities.
  2. Posterior tibialis, FDL, FHL, Peroneus longus, Achilles
  3. GMed, G Min, TFL
29
Q

The Anatomic risk factors for Plantar Fascia:

1?

Excessive 2?

Excessive 3?

Foot type 4?

A
  1. LLD
  2. Tibial Torsion
  3. Femoral Anteversion
  4. PF symptoms found in supinated and pronated

foot types.

30
Q

What are the clinical assessments for Plantar Fascia?

A

  • Palpable tenderness over the insertion of plantar fascia at the medial calcaneal tubercle.
  • Diffuse tenderness along lateral and medial calc, DDx would be calcaneal #
  • Positive windlass manoeuvre: pain with passive DF of hallux,

loading PF. Not often seen clinically only in severe cases whereby rupture/ tear is present.

• No swelling, is rare usually indicates other pathology

31
Q

What are the diagnostic imaging for plantar fascitis?

A

Ultrasound: Diagnosis > 4mm, decreased echogencity, -compare bilaterally?

In acute, U/S may show hypervascularity and of surrounding tissues.

U/S is as reliable as MRI, cheaper more timely.

U/S can also be used to determine treatment outcome,

pre and post exam reveals PF to reduce in thickness in

response to Tx.

Plantar spurs are of no diagnostic value unless there is a fracture

32
Q

What are the treatment options for Plantar Fasciopathy?

1?

2?

3?

4?

5?

6?

A
  1. Stretching
  2. Orthotic therapy
  3. Corticosteroids
  4. NSAIDs
  5. ESWT
