Dolphin Therapy Case Studies

The Dolphin Therapy case studies on this page tell the powerful stories of patients who have used this unique support surface.

Dolphin Therapy simulates a fluid environment. This enables full immersion and envelopment,1,2,3 giving outstanding prevention and treatment of skin damage for highly complex patients.4

3,000+ Outstanding Dolphin Therapy Outcomes

The case studies have all been anonymised and grouped into the following themes:

  • Analgesia reduction
  • ‘Long lie’ falls
  • Dolphin Therapy with the Eleganza 5 bed

Dolphin Therapy Benefits

Tissue Symmetry Maintained

Vascular Occlusion Minimised

Tissue Ischaemia Prevented

Analgesia Reduction

A reduction in analgesia, particularly opioids, has a number of benefits. It can help people to get into a better sleep pattern, as they become less drowsy during the day. In turn, this can help to reduce the risk of falls. Additionally, it reduces other unpleasant and dangerous side effects such as constipation, nausea/vomiting and decreased respiratory drive.

The case studies below tell the stories of patients who were able to significantly reduce analgesia requirements after Dolphin Therapy placement.
