中文摘要 | 人體肢段參數(Body segmental Parameters; BSP)是一種應用於人體在空間中運動的基本參數,本研究目的是以核磁照影法(MRI法)測量40位台灣平均21.5歲健康男性,全身分為14個肢段,定義為頭頸、軀幹、上臂、前臂、手掌、大腿、小腿和腳掌,建立人體肢段參數包括肢段之體積、質量、質心及轉動慣量,並與其他相關研究結果進行比較。本研究腳掌以額狀面掃瞄,其他肢段皆以橫切面掃瞄,每一切面10mm、無間隔掃瞄,使用奇異(GE)MRI儀建立T-1影像,設定值為TR: 450~55Omsec, TE: 8.5~IOmsec, FOV: 300×300mm~48Ox48Omm,全身肢段之MRI影像資料,藉由影像分析軟體,數位化每一切片各組織之輪廓,以獲得面積及形心數位化資料再計算出體積,進一步各組織與其密度的乘積求得肢段質量,並且計算獲得質心與轉動慣量資料。研究結果在質量%和質心%在頭頸分別為織21、52.69,軀幹分別為42.28、41.96,上臂分別為3.25、47.16,前臂分別為1.36、40.98,手掌分別為0.54、32.60,大腿分別為13.50、48.56,小腿分別為4.63、41.68,腳掌分別為1.47、47.51。與其他研究比較,總合質量%為99.99%準確度較高,手掌、前臂和軀幹質量%較小,頭頸則較大。整體而言,肢段分界方法的不同,亦會造成質量%、相對質心%和轉動慣量的差異。其差異的因素會受到種族、生活習性、性別、年齡、和運動習性等影響。在尚未建立台灣人體肢段參數的時代,皆是使用外國人研究的資料,所以急需建立本土化的資料。建立本土化的人體肢段參數的價值,對於國人在醫學、人因工程和運動科學等領域之研究,具有重要性與迫切性。 |
英文摘要 | Body segmental parameters (BSP) have been applied in many areas There are forty Taiwanese young people (21.5±1.52yrs) participated in this study MRI were obtained with a GE MM 15-T scanner, metric size 512×512mm. FOV 480~480mm, TR 450~500msec. TE 8.5~lOmsec. thickness 10mm, T1-weighted The MRI digital images were analyzed by medical image software Moreover, this study is being planned to separate human body into different segments, such as "head and neck", "trunk". "upper arm". "forearm". "hand". "thigh", "shank" and "foot" We will collect the data of volume (V), mass (M), center of mass (CM). moments of inertia (I) and rotation radius (R) of each segmental This study result illustrated mass 00 and center of mass % were head and neck 821, 5269, trunk 42.28, 41.96, upper arm 3.25, 47.16, forearm 1.36, 40.98, hand 0.54, 32.60, thigh 13.50, 48.56, shank 4.63, 41.68, foot 1.47、47.51.The total body mass percentage was 99.99%. And, this study compared with other cadaver and vivo studies were lower in hand, forearm and trunk, but higher in head and neck The differences may due to the human race, living style, female or male, age and fitness level of subjects Besides, the definition of segments boundary and coordinate system were also different result with other studies Most previous researches study used cadavers from older persons or male They used few samples This research can provide valuable information and help to many professionals, such as the designer of walking aid, sports facilities, rehabilitation technologists, medical doctors and sports science researches to provide valuable references |
