Table 1 The Beighton Hypermobility Scoring system is designed to quantify joint laxity and hypermobility. It uses a simple 9-point system, where the higher the score the higher the laxity. The threshold for joint laxity in a young adult ranges from 4 to 6. Any score above 6 indicates hypermobility, but is not necessarily true [25, 26]
