Periodic leg movements during sleep (PLMS) are a frequent finding in nocturnal sleep registrations that include tibialis anterior electromyographic signals. Different PLMS scoring rules exist and can have a major impact on PLMS frequency, which tends to be underappreciated. There is no consistent evidence that frequent PLMS are a causal risk factor for clinically significant outcomes. Several critical open questions are identified that need to be addressed, including but not limited to the consideration of the full range of all sleep-related leg movement activity.
周期性肢体运动在睡眠中（PLMS）是夜间睡眠记录中常见的发现，包括胫骨前肌肌电图信号。不同的 PLMS 评分规则存在，并且可以对 PLMS 频率产生重大影响，而这种影响往往被低估。没有一致的证据表明频繁的 PLMS 是导致临床显著结果的因果风险因素。确定了几个需要解决的关键开放性问题，包括但不限于考虑所有与睡眠相关的腿部运动活动的全部范围。
