“…In fact, few examples of full-field strain measurement exist in this domain, and our previous work on knee braces [32] is unusual. Pressure exerted by a compression textile is commonly measured using pointwise measuring systems, for example, in [36][37][38][39], and full-field pressure fields could only be found for scoliosis braces [40,41], although a preliminary work has been proposed recently [42].…”

Low back pain represents a major economic and societal challenge due to its high prevalence. Lumbar orthoses are one of the recommended treatments. Even if previous results showed their clinical effects, the detailed mode of action is still poorly known, making the device design difficult. A renewed instrumentation and experimental protocol should bring better insight into the lumbar brace–trunk mechanical interaction. This instrumentation should give detailed information on the basic physical or geometrical parameters: the pressure applied on the trunk, the body shape and the strain in the belt. The principal objective of this study was to propose and validate a new measurement protocol, based on pressure mapping systems and full-field shape and strain measurement. The feasibility of the protocol was tested along with its validity and repeatability. The influence of various parameters, which could cause changes in the measurements, was tested with six different belt configurations on one subject. Measurements were also performed to study the impact of posture on pressure and strain. Both pressure and strain appeared to be asymmetric from left to right. The pressure applied by the lumbar belt on the back varies with breathing and with posture. This study showed that full-field measurements were necessary to render the high variability of pressure or strain around the trunk, under recommendations of their use to guarantee a satisfying repeatability.

“…In the medical field, many authors have used pressure measurement to evaluate medical devices. They have been employed to prevent bedsores (Fenety, Putnam, and Walker 2000;Hamanami, Tokuhiro, and Inoue 2004;Reenalda et al 2009;Rithalia, Heath, and Gonsalkorale 2000;Shelton and Lott 2003;Tam et al 2003;Vaisbuch, Meyer, and Weiss 2000)), wheelchair ulcers (Meffre, Gehin, and Dittmar 2007), in the study of rigid or soft braces (Aubin et al 2007;van den Hout et al 2002;Rébecca Bonnaire et al 2014) or more recently for ulcer prevention in diabetic patients (Perrier et al 2014;Bus et al 2016) or even in the study of bandage on animals (Taroni et al 2015). Yet, most work has been developed to measure the interface pressure of compression stockings or compression bandages (Candy, Cecilia, and Ping 2010; Damstra, Brouwer, and Partsch 2008;Dumbleton et al 2009;Hafner et al 2000;Kumar, Das, and Alagirusamy 2013;H.…”

Elastic compression of the lower leg is the traditional preventive and curative treatment of venous insufficiency. After presenting the medical strategies related to compression therapies, this chapter develops current advances in clinics as well as in engineering and outline the more important knowledge arising from this review. Compression hosiery acts by providing pressure to the leg. Pressure generation using socks mainly depends on the stiffness and the size of the socks, the size of the leg, but also the leg morphology. In the case of bandages, the role of friction must be outlined, as the main factor in maintaining the bandage wrapped around the leg, but also as an influencing factor in pressure generation. Besides generated pressure, response of superficial veins to compression also depends on the vein size and the fat stiffness. But mechanical assessments should not mask the importance of other factors such as muscular contraction or nurse formation. An important impact of these results would be head towards an improved personalization of compression treatment.

“…In the medical field, pressure measurement is already used to evaluate devices employed to prevent bedsores, [5][6][7][8][9][10][11] to measure the interface pressure of compression stockings, compression bandages [12][13][14][15][16][17][18] and rigid orthosis. 19,20 Using pressure measurement to mechanically characterize lumbar belts can be considered as new approach.…”

The purpose of this study is to evaluate the possible use of four "FSA" thin and flexible resistive pressure mapping systems, designed by Vista Medical (Winnipeg, Manitoba, Canada), for the measurement of interface pressure exerted by lumbar belts onto the trunk. These sensors were originally designed for the measurement of low pressure applied by medical devices on the skin. Two types of tests were performed: standard metrology tests such as linearity, hysteresis, repeatability, reproducibility and drift, and specific tests for this application such as curvature, surface condition and mapping system superposition. The linear regression coefficient is between 0.86 and 0.98; hysteresis is between 6.29% and 9.41%. Measurements are repeatable. The location, time and operator, measurement surface condition and mapping system superposition have a statistically significant influence on the results. A stable measure is verified over the period defined in the calibration procedure, but unacceptable drift is observed afterward. The measurement stays suitable on a curved surface for an applied pressure above 50 mmHg. To conclude, the sensor has acceptable linearity, hysteresis and repeatability. Calibration must be adapted to avoid drift. Moreover, when comparing different measurements with this sensor, the location, the time, the operator and the measurement surface condition should not change; the mapping system must not be superimposed.
