Increased Range of Joint Movement: Hypermobility and Connective Tissue Evaluation

Increased Range of Joint Movement: Hypermobility and Connective Tissue Evaluation

1. Introduction An increased range of joint movement, clinically recognized as joint hypermobility, occurs when an individual’s joints stretch significantly further than the typical physiological limit. While often viewed simply as being “double-jointed” or an advantageous trait for dancers and gymnasts, excessive joint laxity represents a fundamental alteration in the structural mechanics of the human … Read more

Introduction Thumbs click audibly when bent completely backward due to the sudden mechanical snapping of the flexor or extensor tendons slipping over the bony ridges of the metacarpophalangeal joint, or due to rapid fluid cavitation within the joint capsule. When forced into hyperextension, the complex ligamentous structure of the thumb is stretched to its … Read more
