This observational diagnostic accuracy study will evaluate the ability of the Slump Lateral Bending Test to identify patients with suspected peripheral neurogenic pain or neural mechanosensitivity. Adult participants will be assessed using clinical examination procedures, including the Slump Lateral Bending Test and other neurological and neurodynamic findings. Thes study aims to determine whether this test may help clinicians recognize patients in whom peripheral nerve involvement contributes to symptoms. The results may support clinical reasoning in physiotherapy and improve the assessment o patients with suspected neurogenic pain.
