目的:确定木尔坦不同政府大学学生的椅子人体测量与导致肌肉骨骼问题的生物力学变量之间的关联。
方法:对木尔坦不同政府大学的383名学生进行了横断面研究,巴基斯坦。有23个人体测量,如肩高(SH),肩宽(SB),膝盖高度(KH),pop高度(PH),弯头高度坐姿(EHS),肘部指尖长度(EFL),腹部深度(ABD),臀部-腿部长度(BPL),大腿厚度(TT),前臂宽度(FW),髋部角度(HA),膝部角度(KA),颈椎屈曲(CF),宫颈延长(CE),颈椎侧屈(CLF),颈椎旋转(CR),胸屈(TF),胸部延伸(TE),木材弯曲(LF),木材延伸(LE),木材侧屈(LLF),和木材旋转(LR)。椅子有11种尺寸:座椅高度(SH),座椅深度(SD),座椅宽度(SW),办公桌长度(DL),办公桌宽度(DW),办公桌高度(DH),靠背高度(BH),靠背深度(BD),在木尔坦不同大学的六种常用椅子中,测量了座椅底盘深度(SPD)。这项研究是为了使用组合方程确定椅子的适合度。
结果:大多数学生的人体测量与椅子之间存在巨大差异。推荐的测量值是SH(33.2厘米),SW(43.6cm),SD(42厘米),DH(24.5cm),DL(51.1cm),DW(95厘米),BW(42.6cm),BD(2cm),BH(55厘米),和SPD(4厘米)。
结论:没有发现木尔坦大学使用的椅子是根据学生的人体尺寸设计的,导致肌肉骨骼问题.有必要根据学生的人体测量数据修改椅子的设计,以最大程度地减少肌肉骨骼问题。
OBJECTIVE: To determine the association between anthropometric measurements of chairs and biomechanical variables leading to musculoskeletal problems in students at different government universities in Multan.
METHODS: The cross-sectional study was done on 383 students at different government universities in Multan, Pakistan. There were 23 anthropometric measurements like shoulder height (SH), shoulder breadth (SB), knee height (KH), popliteal height (PH), elbow height sitting (EHS), elbow-fingertip length (EFL), abdominal depth (ABD), buttock-popliteal length (BPL), thigh thickness (TT), forearm width (FW), hip angle (HA), knee angle (KA), cervical flexion (CF), cervical extension (CE), cervical lateral flexion (CLF), cervical rotation (CR), thoracic flexion (TF), thoracic extension (TE), lumber flexion (LF), lumber extension (LE), lumber lateral flexion (LLF), and lumber rotation (LR). There were 11 dimensions of chairs: seat height (SH), seat depth (SD), seat width (SW), desk length (DL), desk width (DW), desk height (DH), backrest height (BH), backrest depth (BD), and seat pan depth (SPD) were measured in six types of commonly used chairs in different universities in Multan. This research was done to determine the fitness of chairs using combinational equations.
RESULTS: There was a huge difference between most anthropometric measurements of students and chairs. The recommended measurements were SH (33.2 cm), SW (43.6 cm), SD (42 cm), DH (24.5 cm), DL (51.1 cm), DW (95 cm), BW (42.6 cm), BD (2 cm), BH (55 cm), and SPD (4 cm).
CONCLUSIONS: None of the chairs used in the universities of Multan were found to be designed according to the anthropometric dimensions of students, resulting in musculoskeletal problems. It is necessary to revise the design of chairs according to the anthropometric data of students to minimize musculoskeletal problems.
