The fact that the fingers of hemiplegic patients spread out after sleeping is mainly considered to be related to the change of body position and the relaxation of the nerves, which is a relatively common phenomenon, but the localized tension abnormality cannot be improved simply by sleeping. In hemiplegic patients, due to the damage of brain tissues and the resulting motor and sensory dysfunction of the limbs, the patients are unable to open their fingers on their own. After sleeping, due to the change of body position, the patient is lying on the back or side, and the nerves are relaxed during sleep, so the phenomenon of finger opening will occur. However, after waking up, the fingers will be in a tense state again and cannot be opened. It is recommended that hemiplegic patients should consult a doctor in a timely manner and undergo rehabilitation therapy under the guidance of a professional doctor as soon as possible, which is conducive to improving the quality of patients’ survival and promoting the recovery of their functions.
