NCT02884323

Brief Summary

This is a single centre open label study measuring lower limb physiology in patients with venous leg ulcers at the University Hospital of South Manchester. Ambulatory venous pressure, venous transit times, wound bed tissue oxygenation and changes in microcirculation will be measured at baseline after the gekoTM device is activated. Ambulatory venous pressure and venous transit times will be performed whilst the participant is standing, sitting and supine

Outcome Measures

Primary Outcomes (1)

  • The acute effect of the geko™ device on ambulatory venous pressure in patients with venous leg ulcers will be evaluated when sitting, standing or supine

    using Lectromed Multitrace II venous pressure recording system, this will measure Ambulatory venous pressure which will show any influence, if any, gekoTM has on AVP.

    2 hours

Secondary Outcomes (4)

  • The acute effect of the geko™ device on lower leg venous transit times

    2 hours

  • The acute effect of the geko™ device on wound tissue oxygen levels

    2 hours

  • The effect of the geko™ device on lower leg microcirculation

    2 hours

  • Adverse events assessments

    2 hours

Study Arms (1)

geko device arm

EXPERIMENTAL
Device: geko™ device

Interventions

The geko™ (T-2 and R-2) devices are small disposable, internally powered, neuromuscular stimulators that are applied externally to the leg.

  • Use of any other neuro-modulation device
  • Current use of TENS in pelvic region, back or legs
  • Use of investigational drug or device within the past 4 weeks that may interfere with this study
  • Recent surgery that may affect the study (such as abdominopelvic, or lower limb) in the opinion of the investigator.
  • Recent trauma to the lower limbs
  • Size of leg incompatible with the geko™ device.
  • Obesity (BMI \> 34)
  • Any medication deemed to be significant by the Investigator
  • Subjects who had an index venous leg ulcer greater in maximum diameter than 10cm in any one dimension, or less than 2cm.
  • Diabetes
  • Clinical evidence of peripheral arterial disease (i.e signs or symptoms, in the opinion of the researcher)
