Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Compression Therapy System Prototype
Identifies legs randomized to receive the experimental intervention
|
A device designed to deliver compression therapy at a pre-set level to the lower leg for legs with a circumference between 30-50 cm.
The device provides compression through a series of three air bladders and is controlled by a battery-powered electronic module that controls compression levels by monitoring bladder pressure.
|
Active Comparator: Coban 2 (2 Layer Compression Wrap)
Identifies the legs randomized to receive the control intervention
|
Coban 2 represents the standard of care 2-layer compression wrap used to treat venous leg ulcers.
The device consists of a comfort layer and a compression layer.
A clinician applies the device to establish compression therapy.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time to Apply Intervention by clinician
Time Frame: Measured on Day 0
|
The time it takes a clinician to place the assigned intervention to each limb
|
Measured on Day 0
|
Time to Apply compression therapy prototype by volunteer
Time Frame: Measured on Day 0
|
The time it takes the volunteer to place the assigned intervention to each limb
|
Measured on Day 0
|
Interface Pressure after Application of Intervention
Time Frame: Measured on Day 1
|
Interface pressure measured by pressure sensor (Pico Press) following application by research clinician
|
Measured on Day 1
|
Average Interface Pressure during Walking
Time Frame: Measured at 0 hours, 1 hour, and 4 hours on Day 1
|
The participant walks on a treadmill for 10 minutes.
A pressure sensor (Pico Press) continuously measures compression at the medial gastrocnemius head.
The interface pressure measurements are averaged over ten minutes of data collection.
The analysis compares changes in pressure over the three measurements for each intervention.
|
Measured at 0 hours, 1 hour, and 4 hours on Day 1
|
Average Interface Pressure during Calf Pumping
Time Frame: Measured at 0 hours, 1 hour, and 4 hours on Day 1
|
The participant pumps each calf independently for 30 seconds.
A pressure sensor (Pico Press) continuously measures compression at the medial gastrocnemius head.
The interface pressure measurements are averaged over 30 seconds of data collection.
The analysis compares changes in pressure over the three measurements for each intervention.
|
Measured at 0 hours, 1 hour, and 4 hours on Day 1
|
Average Interface Pressure during Standing
Time Frame: Measured at 0 hours, 1 hour, and 4 hours on Day 1
|
The participant stands for 30 seconds.
A pressure sensor (Pico Press) continuously measures compression at the medial gastrocnemius head.
The interface pressure measurements are averaged over 30 seconds of data collection.
The analysis compares changes in pressure over the three measurements for each intervention.
|
Measured at 0 hours, 1 hour, and 4 hours on Day 1
|
Average Interface Pressure while laying down
Time Frame: Measured at 0 hours, 1 hour, and 4 hours on Day 1
|
The participant lays down on the bed for 30 seconds.
A pressure sensor (Pico Press) continuously measures compression at the medial gastrocnemius head.
The interface pressure measurements are averaged over 30 seconds of data collection.
The analysis compares changes in pressure over the three measurements for each intervention.
|
Measured at 0 hours, 1 hour, and 4 hours on Day 1
|
Accuracy of Compression Therapy System Prototype compared to Interface Pressure
Time Frame: Measured between 0 and 4 hours on day 1
|
During data collection on day 1, the pressure sensor (Pico Press) will continuously monitor compression level applied to the calf.
Researchers willl compare the pressure applied from the device to the measured pressure at the calf.
|
Measured between 0 and 4 hours on day 1
|
Visual Analogue Sensory (Pain) Assessment
Time Frame: Measured on Day 1 at hour 4
|
Pain assessment completed by a 0 to 10 visual analog scale where 0 represents no pain and 10 represents severe pain.
|
Measured on Day 1 at hour 4
|
Visual Analogue Skin Redness Assessment
Time Frame: Measured on Day 1 at hour 4 for both interventions; Measured on Day 2 - 4 for Compression Therapy System Prototype
|
Visual Analogue Scale between 0 (no redness) to 10 (severe redness)
|

Usability Assessment
Time Frame: Completed on Day 1 for both interventions and daily on Day 2, 3, and 4 for the compression therapy system prototype
|
Questionnaire that allows research participants to score each intervention on a 1 (Strongly disagree) to 5 (Strongly agree) scale for the following questions: The intervention stayed in place while you are wearing it. The appearance of the intervention is aesthetically appealing The dimensions of the intervention are appropriate The weight of the intervention is comfortable when wearing it Overall I was able to successfully use the compression therapy prototype The user manual is helpful for me in managing the compression therapy prototype The instructions in the user manual are understandable (compression therapy prototype only) Overall, the Compression Therapy System Prototype is user friendly Overall, I feel comfortable when I use the intervention Overall, I feel confident when I use the intervention Overall I feel there is no risk to me when I use the intervention |
Completed on Day 1 for both interventions and daily on Day 2, 3, and 4 for the compression therapy system prototype
|
At home usability assessment
Time Frame: Day 2 and 3
|
Questions will be asked to healthy volunteers during three day period at home. Volunteers rate their response on a scale from 1 (strongly disagree) to 5 (strongly agree). I learned to use the compression therapy prototype quickly I learned to use the compression therapy prototype easily I easily remember how to use the compression therapy prototype I quickly became skillful with the compression therapy prototype It isn't necessary to have too much previous knowledge to use the compression therapy prototype The instructions for use are clear and easy to understand The LED signs from the compression therapy prototype is accurate Overall, I was able to successfully interpret the LED signs of the compression therapy prototype The LED signs of the compression therapy prototype are understandable and easy to interpret The LED signs were helpful for me in managing the compression therapy prototype The LED signs allow me to correct mistakes quickly and easily |
