背景：工作记忆（WM）问题影响大多数日常生活活动。目的是评估脑损伤后计算机化工作记忆训练是否对日常生活功能有显著影响。方法：将22-63岁的WM缺陷门诊患者随机分为干预组（IG，n = 20）和对照组（CG，n = 18），接受5周的标准康复治疗。IG还接受了Cogmed QM培训计划的WM培训。在干预前（A1）、干预后即刻（A2）和干预后3个月（A3）进行评估。随访结束后，对CG进行计算机培训并进行评估（A4; n = 8）。评估包括WAIS-III数字广度翻转，疲劳影响量表（FIS），运动和处理技能评估（AMPS），Rivermead行为记忆测试-II（RBMT-II）和WM questionnaire.Results：IG改善数字广度和FIS，A1-A2，并显着超过CG的WM问卷，A1-A3。两组的AMPS运动技能都有所改善，AMPS过程技能评分从A1-A3在IG中有显著改善的趋势。训练后（A3-A4），CG在数字广度和RBMT-II方面有所改善。结论：WM训练似乎对功能活动和减轻疲劳有广泛的影响。
Background: Working memory (WM) problems influence most activities of daily living. The aim was to evaluate if computerized working memory training after brain injury has a significant effect on functioning in daily life.Method: Outpatients with WM deficits, aged 22-63 years, were randomized to either intervention group (IG, n = 20) or control group (CG, n = 18) and received 5 weeks standard rehabilitation. The IG also received WM training with the Cogmed QM training program. Assessments were made before (A1), immediately (A2) and 3 months (A3) after intervention. After follow-up, the CG was offered the computerized training and assessed after this (A4; n = 8). Assessments included the WAIS-III Digit span reversed, Fatigue Impact Scale (FIS), Assessment of Motor and Process Skills (AMPS), Rivermead Behavioural Memory Test-II (RBMT-II) and a WM questionnaire.Results: The IG improved on digit span and FIS, A1-A2, and significantly more than the CG on the WM questionnaire, A1-A3. Both groups improved in AMPS motor skill and the AMPS process skill score tended towards significant improvement in the IG, from A1-A3. After training (A3-A4), the CG improved in digit span and RBMT-II.Conclusion: The WM training seems to have a generalized effect on functional activity and lessens fatigue.
