Hello,
i am trying to figure out which test are good NOT to screen / rule out, but to "confirm diagnosis" and "rule in" disc, radiculopaty, facet joint, instability, hypo mobility, etc.

Also, i would be interest in reliable value of SN, SP, LR+, LR- for these tests and tips about "when to use them":
- SRL
- SLUMP
- Passive Lumba Extension Test
- Prone Instability Test
- PPIVM and PAIVM (for hypomobility OR hypomobility?)
- Extension-rotation Test
- Centralization fenomenon
