Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Limb Volume (ml)
Lasso di tempo: Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|
Limb volume changes measured via perometry reported in change of ml of fluid.
A negative value is associated with the clinically-desirable decrease in fluid.
|
Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|
|
Limb Volume (% Change)
Lasso di tempo: Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|
Limb volume changes measured via perometry reported in percent reduction.
A negative value is associated with the clinically-desirable decrease in fluid.
|
Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|
|
Change in Skin Tone
Lasso di tempo: Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|
Change in skin tone (fibrosis) measured via tonometry.
The tonometer is a mechanical device that gives an indication of the resistance of tissue to compression.
It is used in lymphedema to give an estimate of the extent of pitting and fibrotic induration.
Tonometry measures were collected at 5 anatomical locations.
A negative value is associated with a clinically desirable decrease in tone.

Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|

Patient Reported Outcomes - MYMOP
Lasso di tempo: Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|
Changes in patient-determined symptoms* and change in affect the symptoms had on the subject. Measured via MYMOP (Measure Yourself Medical Outcome Profile) questionnaire. A low score indicates a good outcome. Scores range from 0 (as good as can be) to 6 (as bad as can be). *Recorded symptoms were: Gr A, 1st symptom: none, abdominal pain and discomfort, swelling, physical, and worrying about granddaughters Gr B, 1st symptom: arthritis, hayfever, look of fat foot, right hand area of neck and shoulder, stairs, and swelling Gr C, 1st symptom: none, energy during dancing and gardening, frustration of not going out on own, swelling, mild longstanding depression, and MPT joint at base of small toe Gr A, 2nd symptom: fatigue, heaviness of leg, mental, and pain under knee Gr B, 2nd symptom: narrowed choice of footwear, shower in bath, and swollen left foot Gr C, 2nd symptom: being tired and aching all over, and shoes and clothing |

Cellular Fluid Changes (Ohms)
Lasso di tempo: Change after initial treatment on day 1 and change baseline to end of day 5 for all groups
|
Changes in extra cellular fluid (ECF) on treated leg measured by bioimpedance.
A negative number is indicative of a clinically desirable reduction in ECF.

|
|
Cellular Fluid Changes (% Change)
Lasso di tempo: Change after initial treatment on day 1 and change baseline to end of day 5 for all groups
|
Changes in extra cellular fluid (ECF) on treated leg measured by bioimpedance.
A negative number is indicative of a clinically desirable reduction in ECF.
|
Change after initial treatment on day 1 and change baseline to end of day 5 for all groups
|
|
Incidence of Complications
Lasso di tempo: Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|
Number of complications experienced.
Incidence based on clinician assessment.
|
Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|
|
Activity Level
Lasso di tempo: Day 1 compared to final treatment day (day 12 for Group A and day 5 for Groups B and C)
|
Change in number of steps as accumulated each day monitored through use of a pedometer.
A positive number indicates an increase in step count (activity) while a negative number indicates a decrease in step count.
|
Day 1 compared to final treatment day (day 12 for Group A and day 5 for Groups B and C)

Change in Skin Thickness
Lasso di tempo: Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|
Change in skin thickness measured by ultrasound.
Ultrasound measures were collected at 5 anatomical locations.
A negative value is associated with a clinically desirable reduction in skin thickness (a surrogate measure of oedema).
|
Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|
|
Change in Local Tissue Water (LTW)
Lasso di tempo: Change baseline to final day (day 12 for Group A and day 5 for Groups B and C)
|
Change in local tissue water (LTW) within the skin measured by MoistureMeterD (MMD).
MMD measures were collected at 5 anatomical locations using 2 probes: medium (M25) and large (L50).
A negative value is associated with a clinically desirable decrease in LTW (a surrogate measure of oedema).
