BHSII Manual Score calculation: formula for obtaining a normalized score for each domain and the complete BHSII (scale from 0 to 100).

Domain	Formula	Results
Pain (P)	100– $\frac{(P 1 + P 2 + P 3 + P 4 + P 5 + P 6 + P 7 + P 8 + P 9 + P 10 + P 11 + P 12) \times 100}{48}$	= BHSII Pain
Stiffness (S)	100 – $\frac{(S 1 + S 2 + S 3 + S 4 + S 5) \times 100}{20}$	= BHSII Stiffness
Function (F)	100 – $\frac{(F 1 + F 2 + F 3 + F 4 + F 5 + F 6 + F 7) \times 100}{28}$	= BHSII Function
Visual examination (V)	100 – $\frac{(V 1 + V 2 + V 3) \times 100}{12}$	= BHSII Visual Ex.
Manual examination (M)	100 – $\frac{(M 1 + M 2 + M 3 + M 4 + M 5 + M 6 + M 7) \times 100}{28}$	= BHSII Manual Ex.
BHSII	100 – $\frac{t o t a l s c o r e o f t h e c o m p l e t e q u e s t i o n n a i r e \times 100}{136}$	= BHSII Total Score

The formula required is: normalized score = 100 – $\frac{t o t a l s c o r e o f e a c h s u b s c a l e \times 100}{m a x i m u m p o s s i b l e s c o r e f o r t h e s u b s c a l e .}$
