Clinical Trial Summary

Investigators conducted a prospective study of cancer patients to investigate the efficacy, quality of life, satisfaction, and safety of a home-based intermittent pneumatic compression (IPC) device during the maintenance phase of lower extremity lymphedema. This device has a unique mode designed to mimic the manual lymphatic drainage (MLD) technique and thereby gently facilitate lymphatic draining of proximal extremities.

Intervention

Device:
home-based intermittent pneumatic compression (IPC) device
During the intervention, two programmed modes were used. The first mode, which mimics the MLD massage technique, begins with the inflation of the proximal chamber. After reaching the target pressure, the next chamber consecutively inflates while the initially inflated proximal chamber deflates. The inflation time of each chamber is 3 seconds with holding time of 1 second. The deflation and resting time of each chamber is 7 seconds (pressure setting: 40-60 mmHg). After 30 minutes of the first mode, the second mode, which is the conventional mode of sequential inflation from distal to proximal chambers while sustaining the pressure of the previously inflated chambers, was applied for 30 minutes (pressure setting: 80-100 mmHg, inflation time of each chamber: 6 seconds, holding time: 1 second, deflation time of each chamber: 7 seconds). Participants were instructed to use the IPC device with that 1-hour cycle twice a day for four weeks.

Outcome

Type Measure Description Time frame Safety issue
Primary Change of Inter-limb volume difference ratio Investigators measured three leg volumes: the distal leg volume (distal volume: from the smallest circumference at the ankle (B-measure) to the calf circumference right below the knee bend (D-measure)), the whole leg volume (limb volume without the foot up to the mid-thigh region (F-measure)), and the proximal leg volume (subtraction of the distal leg volume from the whole leg volume) Baseline, after 1 month (4-week)
Secondary Change of Quality of life (Lymph-ICF-LL) Lymphedema Functioning, Disability, and Health Questionnaire for Lower Limb Lymphedema (Lymph-ICF-LL).
Questionnaire contains 28 questions divided into 5 domains: physical function, mental function, general tasks/household activities, mobility activities, and life domains/social life. Each question is scored from 0 (not at all) to 10 (a lot), with lower scores representing better QOL. The total scores and 5 domain scores were calculated by summation.
Baseline, after 1 month (4-week)
Secondary Participant satisfaction questionnaire The questionnaire contained 6 items related to the subjective effects of the IPC device related to volume reduction, pain, heaviness, skin hardness, ease of use, and overall satisfaction with the home therapy offered by the device. Each question was answered using a 5-point scale from 1 (not at all) to 5 (very much). after 1 month (4-week)
