Aim of the present study was to evaluate whether the presence of body shadows during virtual reality (VR) training with BTS NIRVANA (BTs-N) may lead to a better functional recovery.
We enrolled 20 poststroke rehabilitation inpatients, who underwent a neurocognitive-rehabilitative training consisting of 24 sessions (3 times a week for 8 weeks) of BTs-N. All the patients were randomized into 2 groups: semi-immersive virtual training with (S-IVTS group) or without (S-IVT group) body shadows. Each participant was evaluated before (T0) and immediately (T1) after the end of the training (Trial Registration Number: NCT03095560).
The S-IVTS group showed a greater improvement in visuo-constructive skills and sustained attention, as compared with the S-IVT group. The other measures showed nonsignificant within-group and between-group differences.
Our results showed that body shadow may represent a high-priority class of stimuli that act by "pushing" attention toward the body itself. Further studies are needed to clarify the role of body shadow in promoting the internal representation construction and thus self-recognition.
本研究的目的是评估在使用BTS NIRVANA(BTs-N)进行虚拟现实(VR)训练期间身体阴影的存在是否可能导致更好的功能恢复。
我们招募了20名中风后康复住院患者,他们接受了由24节(每周3次,共8周)BTs-N组成的神经认知康复训练。所有患者被随机分为2组:有身体阴影的半沉浸式虚拟训练(S-IVTS组)或无身体阴影的半沉浸式虚拟训练(S-IVT组)。在训练开始前(T0)和训练结束后立即(T1)对每位参与者进行评估(试验注册号:NCT03095560)。
与S-IVT组相比,S-IVTS组在视觉建构技能和持续注意力方面有更大的改善。其他测量结果显示组内和组间差异无统计学意义。
我们的结果表明,身体阴影可能代表一类高优先级的刺激,通过将注意力“推向”身体本身来发挥作用。需要进一步的研究来阐明身体阴影在促进内部表征构建从而自我识别方面的作用。
