Pregnancy significantly increases joint laxity, especially in the third trimester, as measured by a sensitive hyperextensometer. This laxity is more pronounced in women expecting their second child compared to their first.

Area of Science:

Orthopedics
Physiology
Women's Health

Background:

Joint laxity can be influenced by hormonal changes during pregnancy.
Quantifying peripheral joint laxity requires sensitive measurement tools.

Purpose of the Study:

To investigate changes in peripheral joint laxity during pregnancy.
To compare joint laxity between primigravidae and multigravidae.

Main Methods:

Studied 68 females to assess peripheral joint laxity.
Utilized a finger hyperextensometer for metacarpophalangeal joint laxity.
Employed Beighton et al.'s modification of the Carter and Wilkinson scoring system.

Main Results:

A sensitive hyperextensometer showed increased joint laxity in the third trimester of pregnancy.

No change in laxity was recorded using the Beighton et al. scoring system.

Significantly greater laxity was observed in multigravidae compared to primigravidae.

Conclusions:

Peripheral joint laxity increases during late pregnancy.
Laxity increase is more substantial with subsequent pregnancies, particularly the second.
Sensitive measurement tools are crucial for detecting subtle physiological changes during pregnancy.
