Medical compression stockings failed or didn't reach expected positive functions in practical uses, one of the reasons is related to the inaccurate or inappropriate of pressure distributions. Three-dimensional (3D) scanning and analysis were carried out to extract human anthropometric data. Knitting parameters were engineering designed and theoretical pressure profiles were predicted by mathematical models, according to integrative considerations of Standard, leg morphology and machine parameter setting. The predicted pressure distributions for Class I, II & III MCSs generally in predefined ranges. The actual measured pressure values were greater than predicted at all tested regions for Series 1 of MCSs. The MCSs combined structure A and B at calf region make the effect of homogenizing pressure around calf cross-section. It's feasible and valuable to develop MCSs based on knitting parameters, 3D body scanning individually and pre-defined pressure distribution ergonomically to match directly patient-specific medical requirements and healthcare.

In this study, it is postulated that information based on skin layer deformation is necessary for the design of next-to-skin functional cycling suit. Especially for shoulder–chest region, shoulder–back region, waist–abdomen region and waist–hip region, which are critical factors in contact comfort sensations. The skin length deformation during three different road conditions (including uphill, downhill and normal road) and four cycling motions in various longitudinal, horizontal and curved directions were measured. The amount of skin deformation was slightly different for each of the five subjects, but the basic tendency of boundary between extension and contraction of skin surface was very much within the same region. The research results will help to improve cycling clothing in terms of function and comfort under the premise of the adaptation of human movement. [ABSTRACT FROM AUTHOR]

The garment pressure comfort sensation and discrimination were studied in the paper. The garment pressure comfort threshold and difference threshold were defined and calculated according to staircase method of psychophysics. In experiment, 10 subjects were employed in sensory tests and pressure measurements. A novel stretchable compressive belt was developed, which was used to control the pressure applied on separate body parts by its extension and intention, and the subjects judgement and pressure monitor were recorded in times. Finally, the comfort thresholds at nine separate body parts below waistline and difference thresholds at three parts & three varied standard pressure levels were investigated. This study provided proper comfort pressure range to human body for developing compression wear. Practitioner summary: Garment pressure comfort and difference threshold were firstly defined and calculated according to staircase method of psychophysics. The comfort thresholds at nine body parts and difference thresholds at three parts & three varied standard pressure levels were investigated. This study provided proper comfort pressure range to human body for developing compression wear. [ABSTRACT FROM AUTHOR]
