Physical Condition in Lipedema and Obesity
Muscle Strength and Physical Fitness in Patients With Lipedema and Obesity: a Prospective Cross-sectional Pilot Study
Study Overview
Status
Intervention / Treatment
Detailed Description
Lipedema is a genetically mediated disorder of adipose tissue that occurs exclusively in women. Lipedema is an under-recognized condition, often misdiagnosed as lymfedema or dismissed as simple obesity. The diagnosis of lipedema is a clinical diagnosis and may be challenging to determine among patients who are obese. Measurements of muscle strength and physical fitness may give more clarity to differentiate between lipedema and obesity. This may lead to improvements in the criteria of diagnosing lipedema. The research question of the study is: Is there a difference in muscle strength between adult women with lipedema and adult women with obesity?
In this study 40 patients will be studied; 20 patients in every group. Besides the general data as length, weight, age, abdominal circumference, volume of the legs additional muscle strength and physical fitness of women with lipedema and women with obesity will be measured and analysis.
This study doesn't involve a negligible risk for participants. The study will not have direct benefit for the participants, but may be useful in giving more clarity in defining the phenotype for patients with lipedema.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The main determinant of this study is a muscle strength test of the Quadriceps muscle of the left and right leg measured with the MircoFET.
Time Frame: June 2013
|
Muscle strength will be measured with the MicroFET.
This test is performed when de patient is sitting.
The patient is instructed to perform knee extension three times for each leg.
The test result is de average score of each leg.
The MicroFET has been shown to be a valid measurement with the break-method.14,15
Schaubert et al.15 and Bohannon et al.14 looked at the reliability of MicroFET measurements and found a good Intraclass Correlation Coefficient (ICC) values of 0.807-0.97115
and ICC>.097014 respectively.
The test procedure of the break-method is described in Appendix 1).

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
walking capacity
Time Frame: June 2013
|
After performing the muscle strength test, the participants will be asked to perform a test for physical fitness, knowing the Six Minute Walk Test (6MWT).
Walking capacity will be measured with the 6MWT.
This standardized test is performed on a 30 meters course where every five meter is marked.
The patient will be instructed to cross a maximum distance in six minutes with a possibility to stop or rest if necessary.16
The result is the walking distance in meters (m) after six minutes (with five meter exactness).
The 6MWT is a good test for functional activity.
De walking distance performed with the 6MWT gives a good sight in the amount of activities in daily living (ADL) of the performer.17
Rjeski et al.17 found a good validity and correlation with the VO2max (r=0.64) for participants with chronic obstructive pulmonary disease (COPD).
The test-retest reliability of this test is good (ICC 0.94).18
