Summary: This study investigated the impact of dual-task interference on gait, balance, and cognitive function in stroke survivors. Results showed that dual-task interference significantly affected gait performance, balance, and cognitive abilities in individuals post-stroke. The degree of interference, whether in motor or cognitive tasks, had distinct effects on different aspects of function and performance in this population.

Summary: Magnetic resonance imaging (MRI) is a non-invasive tool widely used for measuring human brain properties. However, there is a lack of processing pipelines for multi-modal MRI data, and the reliability and validity measures are inadequate. To address this, PhiPipe, a multi-modal MRI processing pipeline, was developed and evaluated. PhiPipe showed comparable or better reliability and validity compared to two popular single-modality pipelines. It provides a user-friendly solution for multi-modal MRI data processing and includes reliability and validity assessments to aid researchers in experimental design and statistical analysis. This study also presents a framework for evaluating the reliability and validity of image processing pipelines.

Summary: This study aimed to evaluate the reliability and validity of the Insomnia Severity Index (ISI) in the population of people with chronic obstructive pulmonary disease (COPD). The results showed that the ISI had good internal consistency and construct validity in the COPD population, and correlated significantly with measures of depression, anxiety, fatigue, and dyspnea. This suggests that the ISI can effectively measure the severity of insomnia in COPD patients.

Summary: This study aimed to investigate the test-retest reliabilities of unconventional measures of quiet standing balance control in people with chronic stroke. The results showed that centre of pressure measures extracted from a single 30-second quiet standing trial may have sufficient reliability for some chronic stroke research studies, but clinical applications may require the average of at least two trials.

Summary: This study validates the accuracy and reliability of the Odonate system for gait analysis and demonstrates its ability to identify abnormal gait patterns. Compared to the traditional Vicon system, Odonate shows high consistency in measuring certain spatiotemporal parameters and joint angles. However, its consistency in gait phase division and ankle joint angle measurement is slightly lower. Odonate has the potential to provide accessible and objective measurements for clinical gait assessment.

Summary: Radio Frequency Identification (RFID) is a key technology in the Internet of Things (IoT) for locating objects. This work presents a system called RFCamera, which utilizes images to accurately identify and locate RFID-tagged objects. By treating images as visual angle of arrival (AoA) profiles, the system can highlight the locations of tagged objects. Experimental evaluation shows that RFCamera achieves high accuracy in azimuth and elevation angle estimation, as well as in locating visual entities in images.

Summary: This study analyzed the relative efficacy of mind-body exercises (MBE) such as yoga, Tai-Chi, Pilates, Qigong, and dance in improving functional performance and health-related quality of life (HRQoL) in Parkinson's disease patients. The results showed that Pilates was the most effective in improving functional mobility and balance performance, while yoga and dance were the most effective in improving motor function. Qigong was found to be most effective in improving gait speed. Dance was identified as the most effective exercise for improving HRQoL among PD patients.

Summary: This study compared the efficacy of non-invasive brain stimulation techniques in upper limb stroke rehabilitation. The results indicated that excitatory stimulation protocols showed the most promising effects on improving motor function and activities of daily living in stroke patients. Transcutaneous vagus nerve stimulation appeared to be a potentially effective intervention, but further research is needed to confirm its relative superiority.

Summary: Mobile payment has experienced explosive growth by using NFC and barcodes, with the former being more secure, user-friendly, and convenient. However, due to the lack of NFC modules or security concerns, NFC functionality is not available in almost half of current smartphones. To address this, MagCode proposes a cross-technology communication between NFC reader and camera, utilizing harmless magnetic interference to encode data and achieve communication with NFC-denied or NFC-disabled smartphones. Through extensive evaluations, MagCode demonstrates superior throughput and accomplishes data exchange within an average time of 1.8 seconds.

Summary: This study aimed to summarize the effects of dual-task training on cognitive, physical function, and dual-task performance in individuals with mild cognitive impairment or dementia. The results showed that dual-task training led to significant improvements in attention and functional mobility compared to no intervention, and had greater effects on overall cognitive function, balance, and functional mobility compared to single-task training. However, the effects on dual-task performance were inconclusive due to inconsistent results reported.

Summary: The objective of this meta-analysis was to determine the effectiveness of high-intensity laser therapy (HILT) in improving pain intensity, cervical range of motion (ROM), functional activity, and quality of life (QOL) in individuals with neck pain. The results showed that HILT was effective in improving pain intensity and cervical ROM with moderate quality evidence, but there was low quality evidence that HILT was not effective in improving functional activity.

Summary: Estimating the angle-of-arrival (AoA) of an RF source has been a classical topic in wireless systems, but it is not yet widely used for IoT due to high cost. This work introduces a novel sparse planar array, LSAB, which can estimate the AoA of an IoT device in 3D space using a few antennas connected to a single timeshare channel. The benchmark shows that LSAB performs comparably to a uniform planar array and achieves over 40% performance improvement compared to existing sparse arrays.

Summary: This study evaluated the immediate and long-term effects of 12 weeks of Tai Chi training on dynamic balance and disease severity among individuals with cerebellar ataxia. The results showed that Tai Chi training improved dynamic balance, but this improvement was not sustained during the follow-up period. However, Tai Chi did not benefit disease severity and health-related quality of life in this population.
