- Abstract: Objective To analyze characteristics of video polysomnography （V-PSG） for different clinical phenotypes of sleep related rhythmic movement （SRRM）. Methods The clinical data of patients with sleep related rhythmic movement diagnosed by video polysomnography（V-PSG） monitoring in our sleep center from December 2017 to August 2020 were analyzed retrospectively，their genders，ages，first episode time，clinical types and PSG results were statistically analyzed. Results A total of 21 SSRM patients were performed in 959 sleep monitoring cases，including 16 males （76.2%） and 5 females （23.8%）. The mean age was 27.29±11.64 years old，and 17 cases were ≥18 years old. SSRM first occurred in 9 adults （42.9%），4 children （19%），4 patients （19.0%） with unclear onset age，and 4 patients （19.0%） with adolescent onset. The movement frequency of 21 cases （100%） was lower than 0.5 times per second. The clinical manifestations were head shaking type in 10 cases （47.6%），body shaking type in 1 case （4.8%） and mixed type in 10 cases （47.6%）. 14 cases occurred REM in SSRM cases （66.7%），NREM2 2 cases （9.5%%），NREM2+REM3 cases （14.3%），and awake 2 cases （9.5%）. PSG showed that the sleep efficiency of SSRM patients was decreased，the latency period of REM was prolonged and the total waking time after sleep was prolonged，and the total sleep time and sleep stage ratio were approximately normal. Hamilton anxiety score was greater than 8 in 12 cases （57.14%）. Conclusion Adult SSRM is not uncommon，and it is mostly the first episode in adult life. In adults，SSRM is mainly manifested as head shaking type and mixed type，and the occurrence frequency of REM is the highest. The clinical significance of SSRM and its relationship with REM sleep need to be further studied and evaluated.
