NCT05476913

Brief Summary

This multicentre, randomised geko™ venous thromboembolism (VTE) prevention study will prospectively collect clinical data on VTE occurrences in immobile patients after stroke, who will be randomised, on a 1:1 allocation, to receive either standard of care (Intermittent Pneumatic Compression) or geko™ neuromuscular electrostimulation device. The aim is to assess the prevention of VTE during a follow-up period of 90 days (three months) post-randomisation.

Outcome Measures

Primary Outcomes (1)

  • Frequency of any symptomatic or asymptomatic Deep Vein Thrombosis (DVT) in the calf, popliteal or femoral veins or any Pulmonary Embolism (PE).

    Determine the number of patients diagnosed to have a VTE (DVT and PE), comparing the two groups: geko™ device compared to IPC standard of care. Asymptomatic DVT will be diagnosed using above knee compression Doppler (Compression Duplex Ultrasound) and PE will be diagnosed using ventilation perfusion scan or by computer tomography pulmonary angiogram (CTPA). Compression Dopplers will be conducted any time there is a clinical suspicion of DVT. Above knee compression Dopplers will be conducted at 7 days and 14 days after randomisation, or at patient discharge if patient recovers earlier than 7 d and 14 days post-randomisation.

    From randomisation to 30 days. Compression Dopplers at 7 d (optional) and 14 d after randomisation.

Secondary Outcomes (9)

  • Device Acceptability

    At 14 days after randomisation

  • Device effectiveness

    At 30 days after randomisation

  • Leg pain level using a Numerical Rating Scale (NRS) score

    At 90 days after randomisation

  • Disability using the modified Rankin score

    At 90 days after randomisation

  • Health related quality of life using EQ-5D-5L

    At 90 days after randomisation

  • +4 more secondary outcomes

Study Arms (2)

geko™ T-3 interventional

EXPERIMENTAL

The geko™ device will be applied bilaterally as soon as possible after randomisation and each geko™ device will be used to deliver one 24-hour dose. Devices will be worn continuously and changed every 24 hours. Treatment will be continued for a maximum of 30 days or until patient recovers mobility, or is discharged into the community, or meet other defined criteria, whichever comes earlier.

Device: geko™ device

Intermittent Pneumatic Compression (IPC)

NO INTERVENTION

Control treatment will be IPC using NHS approved devices as used for standard clinical care. They will be applied to both legs as soon as possible after randomisation. They will not be changed unless damaged or soiled. Treatment will be continued for a maximum of 30 days or until patient recovers mobility, or is discharged into the community, or meet other defined criteria, whichever comes earlier.

Interventions

Neuromuscular electrical stimulation of the peroneal nerve

Also known as: geko, NMES
geko™ T-3 interventional

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age 18 years or older
  • Clinical diagnosis of acute stroke (WHO criteria)
  • Within 36 hours of symptom onset
  • Not able to get up from a chair/out of bed and walk to the toilet without the help of another person

You may not qualify if:

  • Inability to gain consent from the patient, or a declaration from a Personal Consultee or Nominated Consultee
  • Unwitnessed onset with a long lie on the floor before admission
  • Clinically apparent deep vein thrombosis at screening
  • Patient is expected to require palliative care within 14 days
  • Patient does not live in the local catchment area and is expected to be transferred to their local hospital for on-going care.
  • Patient has recently been involved in or is currently involved in a clinical trial for either a medical device or medicinal product, within the past 3 months, with the exception: if co-enrolment is not considered to impact adverse events or outcomes in the opinion of the Chief Investigator. (A live document containing a list of approved studies will be included in a reference document made available to all study sites and available upon request)
  • Contraindications for the use of the geko™ device:
  • Allergy to hydrogel constituents
  • Contraindications to IPC:
  • Severe peripheral vascular disease
  • Severe oedema
  • Leg deformities making appropriate fitting impossible
  • Uncontrolled congestive cardiac failure
  • Pregnancy
  • Single or double leg amputations
