A high proportion of patients with restless legs syndrome (RLS) also complain of arm paresthesia but the presence of periodic arm movements (PAM) has never been documented in a sleep laboratory in these patients. We investigated the prevalence of PAM during nocturnal sleep and awakenings in 22 RLS patients. Fifteen patients had a PAM index >5 movements per hour during wakefulness and among them only 3 had a PAM index >5 during sleep. Twenty patients had a periodic leg movement (PLM) index >5 during wakefulness and 17 had a PLM index >5 during sleep. In 42.8% of cases, PAM showed temporal relationship with PLM during wakefulness. These results show that PAM is frequent in RLS and suggest that the basic neurological dysfunction responsible for RLS is probably not located exclusively at the level of the lumbar spinal cord but involves neuronal systems located at upper levels.
