What type of end feel is described by involuntary muscle contraction due to pain?

The type of end feel characterized by involuntary muscle contraction due to pain is identified as spasm end feel. This phenomenon occurs when the body responds to pain or discomfort during movement by activating a protective reflex, causing the muscles to contract involuntarily. This muscle contraction aims to prevent further injury by limiting the range of motion at the joint.

In the context of clinical assessment, a spasm end feel indicates a pathological condition where the normal range of motion is restricted due to the body's response to pain. It often suggests the presence of underlying issues, such as inflammation or injury, prompting the body to adopt a protective mechanism.

Understanding this type of end feel is crucial for athletic trainers and healthcare providers, as it can guide them in assessing the severity of the condition and making informed decisions regarding rehabilitation and treatment strategies.
