Many stroke patients show a lot of positivity when they first start to recover function, both psychologically and in action, and some even work hard night and day to exercise in the hope of an early recovery. The mood is completely understandable! However hard exercise is not necessarily good, because we know that many stroke patients go home to exercise on their own after neurological treatment without life-threatening, and doctors say the same thing, “Go back to exercise”! Then there is a lot of what we can all see, walking with the upper limbs on end, hooking the hands and drawing circles on the feet. This is the typical spastic pattern after stroke hemiplegia, which inhibits further recovery of function and can cause joint contractures and other disadvantages. Self-imposed hard exercise is often a further step toward this incorrect spasticity pattern. Why does this typical spasticity pattern occur? The reason is that after a stroke, the central nervous system is damaged and the brain’s inhibitory effect is weakened, causing the release of primitive neurological reflexes in the lower centers, which in turn causes spasticity, resulting in abnormal movement patterns such as joint reaction, common movement, tension line reflex, grip reflex, positive support radiation, etc. If there is no professional rehabilitation training guidance, and if you exercise hard on your own, a significant number of patients will have these abnormal patterns. If there is no professional rehabilitation training guidance, and if you just exercise hard on your own, a significant number of patients will have these abnormal patterns reinforced to the point that the motor function cannot be further improved, and even delay the treatment, resulting in a lifelong spasticity pattern. Therefore, it is good to exercise hard, but the correct mode of training must be carried out under the guidance of a rehabilitation physician or therapist, otherwise it may be too much!
