The most common mistake in rehabilitation training is unclear diagnosis and blind use of rehabilitation training tools. For example, lumbar plate fractures (isthmus discontinuity) are often combined with lumbar disc herniation, so it is not advisable to forcefully move laterally during manual massage. If there is also slipped vertebrae, the waist should not be overextended during back muscle strength exercises. Therefore, it is necessary to: (a) carefully inquire into the medical history, including sports, injured movements, whether the sport and competition can be continued after the injury, and the current painful movements, etc. (ii) Systematic and comprehensive physical diagnosis and examination Certain special physical diagnosis and examination are often indispensable, such as the diagnosis of functional joint instability after a cruciate ligament rupture of the knee, which often requires the injured leg to do an S-shaped single-leg forward lateral jump to clarify whether there is functional instability of the joint. (iii) Reasonable use of various auxiliary examinations such as X-ray, CT, MRI, etc. For example, a better and less expensive way to diagnose meniscal injury is knee arthrography rather than CT or MRI, and the earliest method of diagnosing cartilage injury in the femoral talus is a push-patellar resistance test of the knee rather than MRI.
