目的近年来出现了多种生物反馈刺激技术来治疗磨牙症，但连续应用振动反馈刺激的效果尚不清楚。本研究阐明了振动反馈刺激通过口腔用具（OA）SB时，振动反馈施加4 weeks.MethodsThis是一个前瞻性的，单臂，开放标签，干预研究的效果。10名被诊断为“明确”SB的参与者在家庭环境中穿着特别设计的OA 45个晚上。基于力的SB检测系统，包括放置在OA内部的压敏压电膜，触发连接到OA的振动器。在前2周适应期（第1 - 15晚）期间停止振动刺激，在4周刺激期（第16 - 43晚）期间施加振动刺激，并在刺激后期间（第44和45晚）再次停止。根据家庭便携式多导睡眠描记仪记录的咬肌肌电活动，计算SB发作次数和持续时间/睡眠小时，并比较第15和45个夜晚（无刺激）和第17和第43夜结果振动刺激后SB发作次数和持续时间明显减少（第15晚与第17晚：分别为p= 0.012和p = 0.012），然后在刺激期后停止振动刺激时显著增加（第43夜与第45夜：分别为p= 0.023和p = 0.023）。结论通过OA进行的应急振动刺激可以连续4周抑制SB相关的咀嚼肌活动，并且可能是SB管理的有效替代方案。//jrct.niph.go.jp/;试验注册号：jRCTs 032190225
PurposeVarious biofeedback stimulation techniques of managing sleep bruxism (SB) have recently emerged; however, the effect of successive application of vibratory feedback stimulation has not been clarified. This study elucidated the effect of vibration feedback stimulation via an oral appliance (OA) on SB when vibration feedback was applied for 4 weeks.MethodsThis was a prospective, single-arm, open-label, intervention study. Ten participants diagnosed with “definite” SB wore a specially designed OA for 45 nights in a home-setting. A force-based SB detection system, including a pressure-sensitive piezoelectric film placed internally in the OA, triggered a vibrator attached to the OA. Vibratory stimulation was withheld during the first 2-week adaptation period (1st–15th nights), applied during the 4-week stimulation period (16th–43rd nights), and again withheld during the post-stimulation period (44th and 45th nights). The number and duration of SB episodes/hour of sleep were calculated based on masseter electromyographic activity recorded with in-home portable polysomnography and compared between the 15th and 45th nights (without stimulation) and the 17th and 43rd nights (with stimulation).ResultsThe number and duration of SB episodes significantly decreased after vibratory stimulation (15th vs. 17th nights:p= 0.012 andp= 0.012, respectively), then significantly increased upon cessation of vibratory stimulation after the stimulation period (43rd vs. 45th nights:p= 0.023 andp= 0.023, respectively).ConclusionContingent vibratory stimulation through an OA may suppress SB-related masticatory muscle activity continuously for 4 weeks and may be an effective alternative for the management of SB.Trial registrationhttps://jrct.niph.go.jp/; trial registration number: jRCTs032190225
