Background:
In paralysed limbs quite often edemas are seen, which might pose problems during rehabilitation. The origin of these edemas is not fully understood.
Methods:
48 patients with hemiplegia and edema of the paralysed arm were studied; in 40 patients lymphoscintigraphic studies (static and dynamic lymphography) were performed.
Results:
In 80% of these cases lymphatic flow in the paralysed arm was increased compared to the healthy arm. If there was marked edema in the paralysed arm, the increase of lymph flow was considerable (p < 0.01).
Conclusions:
Edemas in hemiplegic extremities are not due to lymphedema, as in lymphedema the lymph flow usually is very slow. They most likely are caused by disorders of filtration and reabsorption, due to a dysfunction of the autonomic nervous system.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
