- Rheumatoid athiritis
- Osteomyelitis
- DVT
- Compartment syndrome
- If the patient is using anticoagulants (To prevent blood clots)
- Uncontrolled high blood pressure
- Unstable cardiac conditions/angina
The pedal pump technique uses what mechanism?
Explain how this mechanism works?
Calf pump mechanism
Dorsiflexion of the foot, the lymphatic vessels are compressed between the soleus and gastrocnemius muscles.
Encouraging the flow of lymph towards the heart.
Whilst performing the pedal pump technique, the recoil of the foot creates what type of pressure?
