Description

Bulbena et al evaluated the different criteria for the diagnosis of joint hypermobility. The essential elements were combined into a new scale. The authors are from the Hospital del Mar in Barcelona, Spain.


Parameters (10)

Finding

thumb

passive apposition of the thumb to the flexor aspect of the forearm, separated by < 21 mm

metacarpophalangeal

with the palm of the hand resting on the table, the fifth finger can be passively dorsiflexed >= 90°

elbow hyperextension

passive hyperextension >= 10°

external shoulder rotation

with the upper arm touching the body and with the elbow flexed to 90°, the forearm is taken in external rotation up to >85° of the sagittal plane (shoulder to shoulder line)

hip abduction

in the supine position, passively abducted to >= 85°

rotular hypermobility

in the supine position and with the proximal end of the tibia held in one hand, the rotula (patella) can be moved well to the sides with the other hand

ankle and foot hypermobility

in the supine position, excessive passive dorsiflexion of the ankle and eversion of the foot

metatarsophalangeal

in the supine position, dorsal flexion of the toe over the diaphysis of the first metatarsal to >= 90°

knee hyperextension

in the prone position, the heel can make contact with the buttock

ecchymoses

bruising after minimal trauma

 

total score =

= SUM(number of findings present)

 

Interpretation:

• minimum score: 0

• maximum score: 10

• The higher the score, the greater the joint mobility.

• For men, joint hypermobility was defined with a score >= 4.

• For women, joint hypermobility was defined with a score > =5.
