What is spondylolisthesis?

Spondylolisthesis is characterized by the forward displacement of a vertebra, most commonly occurring in the lumbar spine. This condition arises when one vertebra slips over the one below it, which can alter spinal alignment and may lead to pain, nerve compression, and other complications.

This forward displacement often results from various factors, such as degenerative changes, trauma, or congenital defects. Patients may experience symptoms like back pain, leg pain, or muscle weakness, depending on the severity of the slippage and any associated nerve involvement.

Understanding the nature of spondylolisthesis is crucial in kinesiology, particularly when assessing spinal stability, function, and rehabilitation strategies for affected individuals.
