Knee Height Equation
Knee Height Equation. 43.5 in (waist height) horizontal: On multivariable linear regression analyses, arm span and sex, half arm span and sex, and knee height and sex significantly predicted height measurement (p<0.05) (table 5).
In the height prediction equation using knee height, 1 cm increase in knee height was associated with a 1.63 increase in height cm (p < 0.001) while after controlling for sex. Measuring height of bedridden patients can be difficult. The patient's height is then estimated using a standard formula.
Height (Cm) = 84.88 + (1.83 × Kh [Cm]) − (0.24 × Age [Y]).
Formulas can be found in the original paper. With a special formula, this information can be used to estimate the full body length. Height (cm) = 75 + (1.91 × kh [cm]) − (0.17 × age [y]) [8].
Two Equations Were Established To Predict Height Using Kh:
58 in (shoulder height) horizontal: 62 (lowest) 58 in (shoulder height) vertical: —(2_69xkh)+24.2 standard error 1.1 cm stature in cm, kh knee height in cm
Height (Cm) = 64.14 + (2.02 × Kh [Cm]) − (0.04 × Age [Y]);
80 in the present study knee height too showed a positive linear relationship with height (r = 0.740 for males & 0.668 for females) while li et al 12, shahar & pooy 4 and fatmah 8 showed a better correlation between these Stature (cm)=59.01+ \(\left(2.08{\times}knee\ height\ \left[cm\right]\right)\) 25 in (knee height) horizontal:

10.1 Equations For Calculating Height From Knee Height (Chumlea And Guo.
The formula varies based on sex, race, and age. (1) for boys h = 29.895 + (0.081 × age [months] + (2.267 × kh)) and (2) for girls h = 26.297 + (0.110 × age [months] + (2.278 × kh)). In the height prediction equation using arm span, a cm increase in arm span increased height by 0.63 cm (p <0.001) after adjusting for sex.
