Area of Science:

  • Orthopedics
  • Rheumatology
  • Human Biology

Background:

  • Joint hypermobility is understudied in Southeast Asia.
  • Previous research predominantly originates from Western populations.

Purpose of the Study:

  • To determine the joint mobility profile in a Singaporean population sample.
  • To establish the prevalence of joint hypermobility among healthy individuals in Singapore.

Main Methods:

  • A cohort of 306 subjects aged 15-39 from Singapore's major ethnic groups (Chinese, Malays, Indians) participated.
  • Joint mobility was assessed using the modified Carter and Wilkinson criteria (Beighton et al.).
  • Sample demographics reflected the 1990 Singapore census data.

Main Results:

  • The prevalence of joint hypermobility was found to be 17%.
  • Joint mobility demonstrated a decline with increasing age.
  • Females exhibited higher joint mobility than males across all age groups.
  • Malays showed the highest joint mobility, followed by Indians, then Chinese.

Conclusions:

  • This study provides the first comprehensive data on joint hypermobility in Singapore.
  • Age, sex, and ethnicity are significant factors influencing joint mobility in this population.
  • Findings highlight the need for further research into ethnic variations in joint hypermobility.
