In the reliability test involving 12 normal participants, each heel pad was tested six times in succession, and adequate reliability was reflected in the intraclass correlation coefficients (0.95, 0.93 and 0.96 for the microchambers, macrochambers and bulk heel pad, respectively). In the clinical assessment involving 20 normal participants and 16 unilateral plantar heel pain patients, diseased heel pads (86.8 ± 22.9, 36.8 ± 7.7 and 46.6 ± 10.9 kPa for the microchambers, macrochambers and bulk heel pad, respectively) were significantly stiffer than unaffected heel pads (66.8 ± 14.1, 25.2 ± 5.7, 34.2 ± 6.6 kPa) and those of normal participants (60.9 ± 11.4, 26.3 ± 6.1, 31.8 ± 6.3 kPa), suggesting that the heel pad with plantar heel pain was associated with loss of elasticity. ? 2015 World Federation for Ultrasound in Medicine and Biology.[SDGs]SDG3Health; Medical imaging; Reliability; Shear waves; Stiffness; Heel pads; Macrochamber; Micro-chambers; Plantar heel pain; Shear wave elastography; Shear flow; adult; Article; B scan; body mass; clinical article; clinical assessment; correlation coefficient; disease association; echograph; elasticity; elastography; female; heel pad stiffness; heel pain; human; intrarater reliability; male; musculoskeletal stiffness; pain assessment; priority journal; shear wave elastography; validation process; echography; foot disease; heel; pain; pathophysiology; physiology; reproducibility; Young modulus; Adult; Elastic Modulus; Elasticity; Elasticity Imaging Techniques; Female; Foot Diseases; Heel; Humans; Male; Pain; Reproducibility of Resultsjournal article10.1016/j.ultrasmedbio.2015.07.004262996852-s2.0-84943580350
