Study type
Interventional
Description of intervention(s) / exposure
An electric stimulation therapy—Bodyflow (Trademark) Therapy—involves the application of electrodes to the limb which delivers a mild transdermal electrical stimulus targeting stimulation of smooth muscle (Tunica media) to promote the stimulation of arterial, venous and lymphatic systems.
Participants will be randomly allocated to one of three treatment groups in total n = 208 participants will be required.
1 Compression therapy (control) n=69
2 Electric Stimulation Therapy (with no compression therapy) n=69
3 Electric Stimulation Therapy and compression therapy n=69
The Bodyflow (Trademark) Electric Stimulation Device is a small portable device suitable for self-administration in the home setting. Recruits to the Bodyflow group will be given a demonstration on the use of Bodyflow by the clinician on recruitment including the placement of the electrodes, management of the battery powered unit. Written instruction are also given to the recruits to reinforce the instructions on the operation of the device. For recruits in the compression and electrical stimulation group, compression is not removed during treatment.
Guidelines for utilising the Bodyflow (Trademark) Therapy is four times daily for 20 minute sessions over 14 weeks, implemented by the participant or an informal carer in the home environment. Electrodes are attached to the lower limb around the wound (not directly over it) or above or below compression therapy if institu. The device is pre-set to a single, non-adjustable specific low frequency found between one and two Hertz, a current that specifically targets smooth muscle. Use of the device can create a pulsing or tingling sensation. There are no reported serious adverse events anticipated from the use of the Bodyflow (Trademark) Therapy.
Adherence to treatment in the Bodyflow group will be automatically logged by the machine. Continuing and ongoing data collection tools will be completed on each assessment visit and subsequent 2 week visit, 6 week visit, 10 week visit and 14 week visit.

Treatment: Devices
Comparator / control treatment
Standard care of compression therapy will be provided to study participants as per sections 1 and 2 of the Flow Chart for the Management of Venous Leg Ulcers (Australian and New Zealand clinical practice guideline for prevention and management of venous leg ulcer) or as outlined by the Best Practice for the Management of Lymphoedema: International Consensus. All care will be provided by registered healthcare professionals with specialist skills in wound care. Participants randomised to the compression therapy group will be encouraged to use the highest compression possible. Participants will be encouraged to use their compression therapy either 24/7 or from waking in the morning to going to bed at night. Financial support to encourage participants to purchase new compression stockings or to increase their level of compression bandaging will be provided. The study will require n=208 in total (69 per study group). To accommodate a 10% attrition of study participants the study will recruit a sample of n=76 per study group: N=228 overall.

Timepoint [4] 331737 0
Over all costs will be assessed by number of clinic visits/home visits, duration of visits, wound dressing products used over the 14 weeks the recruit is enrolled in the trail.

Summary
Brief summary
The trial will consider the clinical effectiveness of electrical stimulation therapy compared to or in combination with compression therapy. People with a lower leg ulcers will be recruited into the study. Participates will be randomised to either (1) continue their current compression therapy (control). (2) to use electronic stimulation therapy (intervention) or (3) use both compression therapy and electric stimulation. Participants in the study group involving electrical stimulation therapy will use a portable stimulation device that can be self administered in the home setting 4 times a day daily for 20 minutes per session. The number of wounds that heal and the percentage of wound size change will be monitored for 14 weeks in total. Fortnightly for the first follow up visit and then monthly. The clinical effectiveness of the treatments will be considered as will cost effectiveness.
