摘要: Abstract Objective The objective of this study was to determine the instantaneous rate loading during manual high-velocity, low-amplitude spinal manipulations (HVLA SMs) in lumbar and thoracic regions compare average rates loading. Methods Force-time profiles were recorded using a hand force transducer placed between doctor chiropractic subject’s back 14 HVLA SM thrusts on asymptomatic volunteers while 3 doctors delivered manipulations. Doctors also 36 posterior anterior mannequin. Data collected at sampling 1000 Hz Motion Monitor software. profile data differentiated obtain reduced custom-written MathCad program analyzed descriptively. Results 1.7 1.8 times higher than loading, unloading 2.1 2.6 SMs. Maximum occurred 102 111 milliseconds prior peak load. 121 154 after These may be useful for further understanding Conclusions where they describing
