背景：当急性感染后3周开始出现多种症状并持续12个月或更长时间时，就会出现长型COVID。高清经颅直流电刺激(HD-tDCS)已经在COVID-19患者中进行了测试；然而，以前的研究没有调查HD-tDCS联合吸气肌训练（IMT）治疗长COVID的呼吸后遗症。
方法：纳入6名个体（4名女性和2名男性），年龄在29至71岁之间，有长期COVID的呼吸道后遗症。他们接受了包括HD-tDCS联合IMT的干预，每周两次，持续5周。在基线和干预5周后进行肺功能和呼吸肌评估。
■HD-tDCS可能通过增加呼吸肌力量来增强IMT效应，效率,和长期COVID患者的肺功能。
BACKGROUND: Long COVID occurs when numerous symptoms begin 3 weeks after acute infection and last for 12 months or more. High-definition transcranial direct current stimulation (HD-tDCS) has been tested in patients with COVID-19; however, previous studies did not investigate the HD-tDCS use combined with inspiratory muscle training (IMT) for respiratory sequelae of long COVID.
METHODS: Six individuals (four women and two men) aged between 29 and 71 years and presenting with respiratory sequelae of long COVID were included. They were submitted to an intervention that comprised HD-tDCS combined with IMT twice a week for 5 weeks. Lung function and respiratory muscle assessments were performed at baseline and after 5 weeks of intervention.
UNASSIGNED: HD-tDCS may enhance the IMT effects by increasing respiratory muscle strength, efficiency, and lung function of individuals with long COVID.
