Hyperkyphotic measures using distance from the wall: validity, reliability, and distance from the wall to indicate the risk for thoracic hyperkyphosis and vertebral fracture

摘要: C7WD is a practical, valid, and reliable measure that could clearly indicate risk of hyperkyphosis vertebral fracture in the elderly. The findings might be particularly use regions difficult to access radiology or for determination those who need further invasive radiologic examination therapy. Purpose To investigate psychometric properties 7th cervical vertebra wall distance (C7WD) determine thoracic spinal fracture, as compared standard Cobb's method. Methods Community-dwelling elderly (n = 104), aged at least 60 years with occiput-wall > 0 cm, were assessed their using rulers specially developed tool an accurate perpendicular from C7 wall: infrared-gun kyphosis (IG-KypDisT). first 15 participants also involved reliability tests by healthcare professional, village health volunteer, caregiver. Within 7 days, all hospital complete lateral plain radiograph (Cobb's method). Results Outcomes had excellent correlation Cobb angles (r 0.87 r 0.92 IG-KypDisT), when used three raters (ICC3,3 0.85-0.99). 7.5 9.5 cm best diagnostic respectively. Conclusion valid good fracture. confirm traditional ruler-based method practical screen monitor severity clinics communities. In addition, measurement IG-KypDisT provided data can saved analysis; it therefore suggested research settings. would promote standardization measurements various
