Musical dual-task training in patients with mild-to-moderate dementia: a randomized controlled trial.

Abstract: Background/aims Dual-task training may improve dual-task gait performance, balance, and cognition in older adults with and without cognitive impairment. Although music has been widely utilized in dementia management, there are no existing protocols for music-based dual-task training. This randomized controlled study developed a Musical Dual-Task Training (MDTT) protocol that patients with dementia can use to practice walking and making music simultaneously, to enhance attention control in patients during dual-tasking. Methods Twenty-eight adults diagnosed with mild-to-moderate dementia were assigned to the MDTT (n=15) or control groups (n=13). The MDTT group received MDTT, while the control group participated in non-musical cognitive and walking activities. The effects of MDTT were evaluated through the primary outcome of attention control, and secondary outcomes of dual-task performance, balance, falls efficacy, and agitation. Results The MDTT group showed a significant improvement in attention control, while the control group did not (P<0.001). A significant effect favored MDTT over control treatment for the secondary outcome of falls efficacy (P=0.02) and agitation (P<0.01). Conclusion MDTT, a music therapy intervention that demands a high level of cognitive processing, enhances attention control, falls efficacy, and helps alleviate agitation in patients with mild-to-moderate dementia.

Acceptance of different design exergames in elders.

Abstract: For promoting the successful aging of elderly residents of Chang Gung Silver Village in Taiwan, five interactive exergames were developed to promote the well-being of the elderly The exergames included both physical games and cognitive games, and were implemented using various computer-based technologies in the Chang Gung Silver Village The exergames were trialed by 39 elderly residents (15 male, 24 female; mean age 795 ± 175 years) of Chang Gung Silver Village Following the trials, the participants were requested to complete a Technology Acceptance Model 2 (TAM2) questionnaire The results showed that the perceived playfulness and perceived usefulness of the exergames were significantly related to the users' usage behavior and intention to use for both the physical games and the cognitive games However, a relationship between the output quality of the game and the usage behavior was apparent only in the case of the cognitive exergames Finally, the impact of social influence on the intention to use and the usage behavior was more pronounced for the physical exergames Overall, the results revealed that the acceptance of exergames by the elderly depends not so much on the awareness of fun in using the game, but the perceived usefulness of the related physical and cognitive abilities

Intraoperative linguistic performance during awake brain surgery predicts postoperative linguistic deficits.

Abstract: Awake craniotomy pursues a balance between extensive tumor resection and preservation of postoperative language function. A dilemma exists in patients whose tumor resection is restricted due to signs of language impairment observed during awake craniotomy. In order to determine the degree to which recovery of language function caused by tumor resection can be achieved by spontaneous neuroplasticity, the change in postoperative language function was compared to quantified intraoperative linguistic performance. The modified, short-form Boston Diagnostic Aphasia Examination (sfBDAE) was used to assess pre- and postoperative language functions; visual object naming (DO 80) and semantic-association (Pyramid and Palm Tree Test, PPTT) tests assessed intraoperative linguistic performance. DO 80 and PPTT were performed alternatively during subcortical functional monitoring while performing tumor resection and sfBDAE was assessed 1-week postoperatively. Most patients with observed language impairment during awake surgery showed improved language function postoperatively. Both intraoperative DO 80 and PPTT showed significant correlation to postoperative sfBDAE domain scores (p < 0.05), with a higher correlation observed with PPTT. A linear regression model showed that only PPTT predicted the postoperative sfBDAE domain scores with the adjusted R2 ranging from 0.51 to 0.89 (all p < 0.01). Receiver operating characteristic analysis showed a cutoff value of PPTT that yielded a sensitivity of 80% and specificity of 100%. PPTT may be a feasible tool for intraoperative linguistic evaluation that can predict postoperative language outcomes. Further studies are needed to determine the extent of tumor resection that optimizes the postoperative language following neuroplasticity.

A scoping study on the development of an interactive upper-limb rehabilitation system framework for patients with stroke

Abstract: This study aims to propose the framework of the interactive upper-limb rehabilitation system with brain-computer interfaces. The system mainly includes an interactive rehabilitation training platform, a rehabilitation database system, and an EEG and EMG acquisition system. The interactive rehabilitation training system platform includes a virtual rehabilitation game system and an interactive upper-limb rehabilitation device by which a user can perform proactive and reactive rehabilitation.

Nerve detection plate, nerve evaluation system, and nerve evaluation method

Abstract: The invention relates to a nerve detection plate, a nerve evaluation system, and a nerve evaluation method. The nerve detection plate is suitable for detecting a nerve, and includes a substrate, and aplurality of detection units disposed on the substrate and spaced apart from one another. Each of the detection units includes an electrode and a conductive wire electrically connected to the electrode. When the electrodes are attached to a nerve, a selected one of the electrodes is configured to receive an input signal via the corresponding conductive wire and to transmit the input signal to thenerve, and each of the electrodes other than the selected one is configured to receive from the nerve a response signal associated with the input signal and to transmit the response signal via the corresponding conductive wire. Since the plurality of electrodes are in contact with each other at intervals, the nerve detection plate can quickly detect the reaction of the nerve through the pluralityof electrodes, so that the injured segment of the nerve can be quickly and accurately located.
