LOWER EXTREMITY LYMPHEDEMA, MAY, RECRUITMENT
This three-arm, prospective, randomized, preliminary study assessed the comparative efficacy of different treatment frequency and duration in achieving a measurable effect on lower extremity lymphedema using the FT device (The outcomes were measured within day, that is, before and after treatment and before and after 5 days of treatment to determine possible long-term differences. The group which had 1 hour of treatment daily continued treatment for 12 days to explore whether this resulted in better outcomes than after 5 days. It was felt that doing this for the other groups would pose too heavy a burden and deter patients from participating in the study.The protocol was approved by the National Research Ethics Service Committee East Midlands, Derby, United Kingdom (revised May 2014). Written informed consent was obtained from all study participants. Recruitment was conducted among patients who presented to the Derby Lymphedema Service between December 2013 and March 2019.
