“…Also, it is impractical because disinfection of the equipment and water replacement are required after each measurement. [28] The reliability of tonometry is no better than that of circumference measurement or volumetry. These results may be due to operational inconsistencies between assessments and raters, especially because it is not easy to apply stable force without fluctuation.…”

Objective: To examine the reliability of ultrasonographic thickness and compressibility along with real-time pressure monitoring to evaluate postmastectomy lymphedema and to suggest a reference range of appropriate pressure. Design: Measurement reliability study. Setting: Research laboratory. Participants: Fifteen patients with prior mastectomy for breast cancer who were diagnosed with secondary lymphedema, and 16 healthy control subjects. Methods: The thickness and compressibility of the subcutaneous layer in the arms of 15 postmastectomy patients with secondary lymphedema were measured using B-mode and M-mode ultrasonography. An ultrasound machine was equipped with a real-time pressure-monitoring device to monitor downward compression pressure on the arms at a constant velocity. The ratio of thickness change defined the compressibility index. Two different experienced examiners participated in the measurement of lymphedema. Intrarater reliability and inter-rater reliability were estimated using the intraclass correlation coefficient. Very good reliability was defined as an ICC of more than 0.8. Main outcome measurements: The thickness of the subcutaneous layer, the compressibility index, and the intrarater and inter-rater reliability were measured.Results: The measured thicknesses demonstrated very good intrarater and inter-rater reliability for the forearm and upper arm. For the compressibility index, the upper arm and forearm had very good intrarater and inter-rater reliability at over 2000 Pa of compression (>0.9). Conclusions: Ultrasonography with real-time pressure monitoring may be useful for evaluating the severity and characteristics of lymphedema, particularly at compression pressures more than 2000 Pa.

“…However, quantifying lymphedema is a challenge because various measurement approaches have been used to define lymphedema and certain types of breast cancer-related lymphedema such as breast, shoulder, and truncal lymphedema cannot be quantified with current measurement technology. Methods of measuring limb volume LV include sequential circumference limb measurement, water displacement, infra-red perometry, and bioimpedance spectroscopy (Armer & Stewart, 2005;Petlund, 1991;Tierney, Aslam, Rennie, & Grace, 1996;Cornish, et al, 2001). …”

“…Patients submerge the affected arm in a container filled with water and the overflow of water is caught in another container and weighed (Figure 3). This method does not provide data about localization of swelling or shape of the extremity (Petlund, 1991;Tierney et al, 1996). The method is contraindicated in patients with open skin lesions.…”

Novel Strategies in Lymphedema

View full text Add to dashboard Cite

Lymphedema is a swelling caused by the abnormal accumulation of lymphatic fluid in the skin. Lymphedema can be caused by burns, injury, surgery, radiation therapy or cancer treatment that cancer survivors undergo. Risk of developing lymphedema is high especially in those with breast or prostate cancer. It is hereditary and can appear without warning at any time of life and is related to obesity and circulatory problems. If not treated, lymphedema can be painful and lead to life-threatening infections. This book will help physicians who deal with lymphedema. It will help you understand how the lymphatic system works, how lymphedema is diagnosed, how to cope with the challenges of lymphedema, how to find treatment, and how to deal with insurance issues.Novel Strategies in Lymphedema is for those with, or at risk of, developing lymphedema, and the healthcare professionals who care for them.

“…All limb volumes were measured and calculated in the clinic utilizing an infrared optoelectronic system (Pero-System, PeroPlus 2000; Juzo, Inc, Cuyahoga Falls, OH). The validity and reliability of the Perometer for limb volume measurement has been established [8][9][10][11].…”

Infrared optoelectronic volumetry, the ideal way to measure limb volume

Abstract: Perometry is a novel, extremely accurate and easy method for assessing limb volume. It provides more accurate results than traditional indirect measurement of limb volume and potentially is a very useful clinical and research tool.
