Outcome Measures

Primary Outcomes (2)

  • Initial Walking Distance Measured by Treadmill

    For the initial claudication distance measurement, a fixed load treadmill test will be carried out at 3.5 km/h with a 10% gradient. The initial claudication distance (ICD) is the distance walked until the onset of pain.

    Change in baseline treadmill walking distance at 6 weeks (positive numbers indicate increase from baseline, negative numbers indicate decrease from baseline) - 6 week - baseline values.

  • Absolute Walking Distance Measured by Treadmill

    For the absolute claudication distance measurement, a fixed load treadmill test will be carried out at 3.5 km/h with a 10% gradient. The absolute claudication distance (ACD) is the distance walked before the participant is forced to stop due to typical pain.

    Change in baseline treadmill walking distance at 6 weeks (positive numbers indicate increase from baseline, negative numbers indicate decrease from baseline)

Secondary Outcomes (6)

  • Femoral Haemodynamics Measured by Femoral Artery Duplex Ultrasonography

    Change in baseline femoral haemodynamics at 6 weeks - 6 weeks - baseline.

  • Laser Doppler Flow Measured by Optical Laser

    Change in baseline flowmetry at 6 weeks

  • Symptomatic Scores by Questionnaire

    Change in baseline questionnaire scores at 6 weeks

  • Quality of Life Scores Measured by Questionnaire

    Change in baseline quality of life at 6 weeks

  • Urine Metabolic Profile

    Change of profile at baseline and at 6 weeks

  • +1 more secondary outcomes

Study Arms (2)

Supervised Exercise Only

NO INTERVENTION

This is the cohort of patients with Intermittent Claudication that will receive standard care of a supervised exercise programme only.

NMES + Supervised Exercise

EXPERIMENTAL

This cohort of patients with Intermittent Claudication will receive the standard care of supervised exercise plus the use of a Revitive IX neuromuscular electrical stimulation device (Intervention) as per the protocol. The adjunctive benefit of the latter intervention compared to standard treatment alone will then be assessed.

Device: Revitive IX

Interventions

This is a neuromuscular electrical stimulation device

NMES + Supervised Exercise

Eligibility Criteria

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

You may qualify if:

  • Patients with intermittent claudication who have the following are eligible for the study:
  • All ethnic groups, male or female above the age of 18 years.
  • Diagnosis of intermittent claudication
  • Be of non-childbearing potential; OR using adequate contraception and have a negative urine pregnancy test result within 24 hours, if appropriate, before using the study device.
  • Blood pressure currently under moderate control (\< 160/100mmHg)
  • No current foot ulceration

You may not qualify if:

  • Patients meeting any of the following criteria are to be excluded:
  • Has an unstable condition (eg, psychiatric disorder, a recent history of substance abuse) or otherwise thought to be unreliable or incapable of complying with the study protocol.
  • Has renal failure
  • Has diabetes
  • Has an ankle-brachial pressure index (ABPI) \>0.9
  • Has any metal implants
  • Pregnant
  • Has a cardiac pacemaker or defibrillator device
  • Has recent lower limb injury or lower back pain
  • Has current foot ulceration or other skin ulcers
  • Has foot deformities
  • Has any disorder that, in the opinion of the Investigator, might interfere with the conduct of the study.
