function to correct the consequences of the injury. these consequences are hypertonicity/spasticity, contractures, painful hyperesthesias and paralyzed proximal upper limb muscles with distal muscle sparing. spasticity is a frequent consequence of incomplete injuries. spasticity often decreases function, but sometimes a patient can control the spasticity in a way that it is useful to their function. the location and the effect of the spasticity should be analyzed carefully before treatment is planned. an injection of botulinum toxin (botox) into spastic muscles is a treatment to reduce spasticity. this can be used to prevent muscle shortening and early contractures. over the last ten years, an increase in traumatic incomplete lesions is seen, due to the better protection in traffic. treatment
