简要总结
This study is investigating the immediate and long-term effects of bilateral cerebellar transcranial direct current stimulation on cognition, balance, and symptom severity in people with sports-related post-concussion syndrome. The central hypothesis is that tDCS will provide improvements in cognitive deficits, balance, and overall symptom attenuation in people with SRPCS both acutely and at 2 and 4 week follow ups. The researchers further hypothesize that cerebellar tDCS will ameliorate the symptoms of people with SRPCS.
详细描述
The long term goal is to develop an effective and broadly applicable treatment modality for athletes who develop SPRCS. The objective of this study is to investigate the effects of multiple (5 consecutive daily) sessions of 2 milliampere (mA) right cerebellar tDCS on cognitive deficits, balance, and overall attenuation of symptoms on people with SRPCS. Cognitive deficits will be assessed with the N-back Working Memory test, list sorting test, and dimensional change card test. Balance deficits will be assessed with the Berg Balance Scale and Standing Balance Test (SBT), and symptoms will be assessed via the Rivermead Post-Concussion Symptom Questionnaire (RPQ). The cognitive and balance tasks are taken from the NIH motor toolbox and have been shown to be the most important for health and success in school and work, and the RPQ is one of the most widely used SRPCS evaluation tools. The central hypothesis is that tDCS will provide improvements in cognitive deficits, balance, and overall symptom attenuation in people with SRPCS both acutely and at 2 and 4 week follow ups. The researchers further hypothesize that cerebellar tDCS will ameliorate the symptoms of people with SRPCS. The rationale is that the results will improve the quality of life of these patients and may prevent impairment of cognitive function later in life.

结局指标
主要结局
Berg Balance Scale
时间窗: 2 weeks
Balance Assessment. This is a 14 item test with scores from 0 to 4, with 4 being no inhibition at all. The max score on this test is 56, higher scores indicating better balance.
List Sorting Working Memory Test
时间窗: 2 weeks
Assessment of Cognition
Flanker Inhibitory Control Test
时间窗: 2 weeks
Assessment of Cognition/
Dimensional Change Card Sorting Test
时间窗: 2 weeks
Assessment of Cognition
Standing Balance Test
时间窗: 2 weeks
Balance Assessment. Outcomes of this test are overall postural sway translated into a normalized t-score.
