McMurray test
- meniscus tears - Your doctor will bend your knee, then straighten and rotate it. This puts tension on a torn meniscus. If you have a meniscus tear, this movement will cause a clicking sound.

51
Nerve conduction studies
NCS : Demyelination vs Axonal neuropathy - Demyelination: Delayed or blocked nerve conduction velocity - Axonal injury: reduced in signal strength/ amplitude. - Myasthenia Gravis: Normal NCS, but decreased motor strength on repetitive stimuli in Muscle Conduction studies.
