To compare the difference in the manual measurement of Fengshi (GB 31) between the standing position and the supine position so as to determine the location.
A total of 197 volunteers were included in the manual measurement of Fengshi (GB 31) at the standing position and 92 volunteers at the supine position. The differences were compared between the two measurements.
The results in the manual measurement at the standing position showed that the distance was (39.27±3.83) cm from the greater trochanter of femur to the popliteal transverse crease [(39.96±4.21) cm in males, (38.82±3.49) cm in females, < 0.05]. The distance was (19.08±2.97) cm from the tip of the middle finger to the popliteal transverse crease [(18.96±3.50) cm in males, (19.16±2.58) cm in females]. After calculating according to the formula of proportional bone measurement, Fengshi (GB 31) was located (9.28±1.44) above the popliteal transverse crease [(9.07±1.64) in males, (9.42±1.29) in females]. The results in the manual measurement at the supine position showed that the distance was (41.89±3.88) cm from the greater trochanter of femur to the popliteal transverse crease [(42.36±3.88) cm in males, (41.67±3.89) cm in females]. The distance was (23.01±3.37) cm from the tip of the middle finger to the popliteal transverse crease [(22.50±3.73) cm in males, (23.25±3.20) cm in females]. After calculated according to the formula of proportional bone measurement, Fengshi (GB 31) was located (10.51±1.69) above the popliteal transverse crease [(10.16±1.75) in males, (10.67±1.63) in females].
Fengshi (GB 31) is located on the femoral region, in the depression under the tip of the middle finger at the standing position. The simple localization of the acupoint at the supine position: at the supine, the palm touches the middle of the lateral side of the thigh, about 1 directly below the depression under the tip of the middle finger. The location of Fengshi (GB 31) in female is slightly upper than male.
比较站立位与仰卧位时风市穴（GB 31）手法测量的差异，以确定其定位。
纳入197名志愿者进行站立位风市穴（GB 31）的手法测量，92名志愿者进行仰卧位风市穴（GB 31）的手法测量。比较两种测量结果的差异。
站立位手法测量结果显示，股骨大转子至腘横纹的距离为（39.27±3.83）cm[男性为（39.96±4.21）cm，女性为（38.82±3.49）cm，P<0.05]。中指指尖至腘横纹的距离为（19.08±2.97）cm[男性为（18.96±3.50）cm，女性为（19.16±2.58）cm]。按骨度分寸法公式计算，风市穴（GB 31）位于腘横纹上（9.28±1.44）寸[男性为（9.07±1.64）寸，女性为（9.42±1.29）寸]。仰卧位手法测量结果显示，股骨大转子至腘横纹的距离为（41.89±3.88）cm[男性为（42.36±3.88）cm，女性为（41.67±3.89）cm]。中指指尖至腘横纹的距离为（23.01±3.37）cm[男性为（22.50±3.73）cm，女性为（23.25±3.20）cm]。按骨度分寸法公式计算，风市穴（GB 31）位于腘横纹上（10.51±1.69）寸[男性为（10.16±1.75）寸，女性为（10.67±1.63）寸]。
风市穴（GB 31）位于股部，站立位时在中指指尖下的凹陷处。仰卧位时穴位简易定位：仰卧，手掌贴于大腿外侧中部，约在中指指尖下凹陷处直下1寸。风市穴（GB 31）女性的位置略高于男性。
