A Study in Patients With Venous Leg Ulcers and Measuring the Effects of Using Geko™ Device

A Single Centre Open Label Pilot Study Measuring Lower Limb Physiology in Patients With Venous Leg Ulcers Using the Geko™ T-2 or gekoTM Plus [R-2] Neuromuscular Electro Stimulation Device

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

Inclusion Criteria:

1. Age ≥ 18 years
2. Intact healthy skin at the site of device application
3. Able to understand the Patient Information Sheet
4. Willing and able to give informed consent
5. Willing and able to follow the requirements of the protocol
6. Subjects who had a chronic venous leg ulcer (i.e. CEAP classification of C6 1) greater than 1 cm2 and less than 10 cm in maximum diameter,
7. ABPI of ≥0.8
8. Patient treated with 4 layer compression bandaging

Exclusion Criteria:

1. Wound infection either acute or chronic
2. History of significant haematological disorders or DVT with the preceding six months
3. Pregnant
4. Pacemakers or implantable defibrillators
5. Use of any other neuro-modulation device
6. Current use of TENS in pelvic region, back or legs
7. Use of investigational drug or device within the past 4 weeks that may interfere with this study
8. Recent surgery that may affect the study (such as abdominopelvic, or lower limb) in the opinion of the investigator.
9. Recent trauma to the lower limbs
10. Size of leg incompatible with the geko™ device.
11. Obesity (BMI > 34)
12. Any medication deemed to be significant by the Investigator
13. Subjects who had an index venous leg ulcer greater in maximum diameter than 10cm in any one dimension, or less than 2cm.
14. Diabetes
15. Clinical evidence of peripheral arterial disease (i.e signs or symptoms, in the opinion of the researcher)
