What does a 'springy block end feel' suggest during joint assessment?

A 'springy block end feel' during joint assessment indicates that there is a rebound sensation at the endpoint of the joint's range of motion. This is not simply a hard stop or a soft tissue resistance; rather, it reflects an elastic or spring-like response when the joint is moved to its limit. This sensation typically suggests the presence of intra-articular pathology, such as a meniscus tear in the knee or loose bodies within the joint.

This characteristic response is distinct from other end feel types, which may indicate different issues such as pain or instability. For instance, a sensation of definite pain before reaching the end range suggests a more acute or reactive condition, normal soft tissue tension would indicate healthy joint mechanics without any underlying pathology, and complete joint dislocation would typically result in a loss of normal joint mechanics rather than a springy sensation. Understanding this springy feel is crucial for clinicians when assessing joint functionality and determining appropriate treatment strategies.
