Benign joint hypermobility syndrome (BJHS), also know as Ehlers Danlos Syndrome (EDS) Hypermobility type III are thought to be inherited connective tissue disorders where there are multiple musculoskeletal complaints in a hypermobile individuals with no evidence of rheumatologic disease. Individuals experience pain in multiple joints, fatigue, and hypermobility that might result in a higher incidence of dislocations and sprains. Doctors often use joint hypermobility mobility screening tests to diagnose this syndrome.
For example:

  • The thumb can be moved down and back to contact the forearm.
  • The little fingers can be extended back beyond 90 degrees.
  • When standing, the knees have a bowing appearance from the side.
  • When fully extended, the arms bend further than normal (beyond straight).
  • The ability to place hands flat on floor with forward bending with knees straight

Your doctor might suggest physical or occupational therapy to help strengthen these joints, and to educate in joint protection strategies, and appropriate home exercise.
