Abstract
Objective: This study aimed to validate a smart-textile based on fiber-optics for simultaneous measurement of plantar temperature, pressure, and joint angles in patients with diabetic peripheral neuropathy (DPN).
Methods: After in-vitro validation in the laboratory, 33 eligible subjects with DPN were recruited (age: 58 ± 8 years, BMI: 31.5 ± 8 kg/m2 ) for assessing plantar pressure and temperature during habitual gait-speed in a clinical-setting. All participants were asked to walk at their habitual speed while wearing a pair of sensorized socks made from highly flexible fiber optics (SmartSox). An algorithm was designed to estimate temperature, pressure, and toe range of motion from optical wavelength generated from SmartSox. To validate the device, results from thermal stress response (TSR) using thermography and peak pressure measured by computerized pressure insoles (F-Scan) were used as gold standards.
Results: In laboratory and under controlled conditions, the agreements for parameters of interest were excellent (r > .98, P = .000), and no noticeable cross-talks between measurements of temperature, angle, and pressure were observed. During clinical data acquisition, a significant correlation was found for pressure profile under different anatomical regions of interest between SmartSox and F-Scan (r = .67, P < .050) as well as between thermography and SmartSox (r = .55, P < .050).
Conclusion: This study demonstrates the validity of an innovative smart textile for assessing simultaneously the key parameters associated with risk of foot ulcers in patients with DPN. It may empower clinicians to objectively stratify foot risk and provide timely care. Another study is warranted to validate its clinical application in preventing limb threating problems in patients with DPN.

创伤是指由于各种致伤因素导致的机体软组织、骨骼甚至内脏器官等等各个系统的损伤,创伤可以根据发生地点、受伤部位、受伤组织、致伤因素及皮肤完整程度进行分类。 按发生地点分为战争伤、工业伤、农业伤、交通伤、体育伤、生活伤等;按受伤部位分为颅脑创伤、胸部创伤、腹部创伤、各部位的骨折和关节脱位、手部伤等;按受伤类型分为骨折、脱位、脑震荡、器官破裂等;相邻部位同时受伤者称为联合伤(如胸腹联合伤);按受伤的组织或器官分类时,又可按受伤组织的深浅分为软组织创伤、骨关节创伤和内脏创伤。软组织创伤指皮肤、皮下组织和肌肉的损伤,也包括行于其中的血管和神经。单纯的软组织创伤一般较轻,但广泛的挤压伤可致挤压综合征。血管破裂大出血亦可致命。骨关节创伤包括骨折和脱位,并按受伤的骨或关节进一步分类并命名。如股骨骨折、肩关节脱位等。内脏创伤又可按受伤的具体内脏进行分类和命名。如脑挫裂伤、肺挫伤、肝破裂等。同一致伤原因引起两个以上部位或器官的创伤,称为多处伤或多发伤。按致伤因素,分为火器伤、切伤、刺伤、撕裂伤、挤压伤、扭伤、挫伤等。按皮肤完整程度,分为闭合性创伤、开放性创伤等。
