Study Evaluating Flexitouch Plus With Connectivity on Compliance in 30 Patients With Breast Cancer-Related Lymphedema.

Study Overview
=================
Brief Summary
-----------------
The objective of this study is to demonstrate the feasibility of using the Flexitouch Plus with Cellular Connectivity (FT-CC) to monitor device use data to determine if reminders to patients impact compliance, and to identify the impact device compliance has on arm girth, quality of life (QOL), and symptom assessment.

Detailed Description
-----------------
This is a multi-center, on label, prospective, randomized, two-arm feasibility study that plans to enroll 30 female subjects in the United States. In an effort to reduce potential exposure to COVID-19, all study assessments are intended to be performed in a contactless manner (i.e., telephone, video conference, etc). If a subject passes the initial screening requirements via medical history and expresses interest in the study an informed consent form will be provided to them. Once consent has been obtained they will undergo a baseline visit where they will be randomized to one of two treatment groups: PASSIVE FT-CC (text messages reminders will not be sent to subjects) and ACTIVE FT-CC (text messages reminders will be sent if subject does not use the device for 2 consecutive days). Randomization was incorporated into the study to determine if ACTIVE FT-CC affects device use. A total of 2 follow-up visits will be conducted over a 60-day period.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Compliance Measured as the Average Number of Treatments Per Week | Compare the rate of compliance in patients treated with PASSIVE FT-CC and ACTIVE FT-CC. | 60 Days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Compliance With Device Use. | Analysis of compliance with prescribed device use. | Through 60 days after device training | 
| Quality of Life Assessment Via LYMQOL ARM | Comparison of quality of life in patients treated with Active FT-CC vs. Passive FT-CC via Lymphedema Quality of Life Tool (LYMQOL ARM). Lymphedema Quality of Life Tool (LYMQOL-ARM) includes sub-scores for Function (range 10-40), Appearance (range 5-20), Symptoms (range 6-24), and Emotion (range 6-24) where lower scores represent a better outcome. It also includes an Overall QOL sub-score (range 0-10) where a higher score represents a better outcome. | Changes through 60 days after device training | 
| Quality of Life Assessment Via SF-36 Physical Functioning Domain Score | Comparison of baseline vs. 60-day follow-up results of the The RAND 36-Item Short Form Survey (SF-36). The RAND 36-Item Short Form Survey (SF-36) taps eight health concepts: physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. It also includes a single item for perceived change in health. Min value: 0, Max value: 100. Higher scores represent a better outcome. | Changes through 60 days after device training | 
| Quality of Life Assessment Via LSIDS-A Score | Comparison of baseline vs. 60-day follow-up results of the LSIDS-A Scoring Tool. The LSIDS-A domains consist of 30 questions in the areas of soft tissue sensation, neurological sensation, function, behavior, resource, sexuality, and activity. Scores are compiled by domain and overall. Overall results will be posted here. | Changes through 60 days after device training |
