Firstkind – geko post-THR

The geko neuromuscular electrical stimulator

A feasibility randomised controlled trial to evaluate the effectiveness of a novel neuromuscular electro-stimulation device in preventing the formation of oedema and deep vein thrombosis following total hip replacement surgery


This study investigated whether the geko™ device is more efficient than compression stockings in preventing the formation of symptomatic/asymptomatic Deep Vein Thrombosis (DVTs), post total hip replacement surgery.

Primary Outcome Measures:

Presence of asymptomatic DVT assessed by Duplex Ultrasound
Presence of oedema

Secondary Outcome Measures:

  • VAS Pain score
  • Adverse event rate

The results of this study suggest that the NMES is a safe and well tolerated alternative to compression stockings, which should be considered by clinicians seeking the additional benefit of reducing post-operative oedema. In addition the NMES device should be considered as part of a DVT prophylaxis. The full reports are published in Surgical Technology and Heliyon. link:
