2016
We developed a real-time mirror robot system for functional recovery of hemiplegic arms using automatic control technology, conducted a clinical study on healthy subjects, and determined tasks through feedback from rehabilitation doctors. This simple mirror robot can be applied effectively to occupational therapy in stroke patients with a hemiplegic arm.

Muscles that Move the Arm

2024
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles. The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Extinction Training During the Reconsolidation Window Prevents Recovery of Fear

2012
Conditioned fear can be diminished through an inhibitory process called extinction, but can resurface under conditions such as the passage of time or exposure to stress. Our protocol presents a novel way of preventing fear recovery by introducing extinction during the reconsolidation window (the re-storage phase of a reactivated memory).

Rats' anxiety-like behavior tested by the elevated plus maze varies highly depending on the testing environment. Here we show how apparatus settings, especially arm structure, affect behavior on the maze, and we explain a reliable protocol to detect effects of anxiolytic drugs. This report will contribute to anxiety research.
FAQs
Neuroplasticity provides the rationale for repeated, task-specific practice: the nervous system may adapt as a person repeatedly performs meaningful movements. Training that focuses on reaching and grasping links rehabilitation with motor control rather than treating strength in isolation. Bioengineering systems can support this process by measuring performance and delivering consistent practice matched to the user’s changing ability.
Reaching and grasping connect physical improvement with functional arm use. Their performance reflects multiple factors, including movement, strength, and coordination, so changes can reveal more than a single impairment measure. In rehabilitation research, analyzing these actions helps clinicians evaluate whether training produces meaningful improvements in how the arm performs practical tasks.
Adaptive technologies adjust assistance or feedback to the user’s ability while maintaining opportunities for active practice. Robotic assistance can support movement, functional electrical stimulation can help deliver task-related input, and virtual feedback can reinforce performance. Together, these approaches allow training to be structured, repeated, and measured without relying only on subjective clinical observation.
Motion sensors provide quantitative information about arm performance during activities such as reaching and grasping. Instead of recording change only through general clinical impressions, clinicians can use measured movement data to track performance and compare progress over time. This information supports personalization of training and helps evaluate whether a rehabilitation strategy is producing measurable change.
A bioengineering workflow can begin by measuring movement and impairment, followed by repeated task-specific training with selected technological support. Robotic assistance, functional electrical stimulation, or virtual feedback may be incorporated according to the user’s ability. Performance is then reassessed to identify changes and guide further personalization, creating a measurement-guided rehabilitation process.
Researchers use these tools when they need to deliver structured practice while measuring or adapting the rehabilitation experience. Robotic assistance can provide movement support, functional electrical stimulation can contribute to the training approach, and virtual feedback can supply performance information. The appropriate technology depends on the study’s training goals and the participant’s functional ability.
These studies can measure changes in impairment and functional performance, particularly during reaching and grasping. Quantified movement data may help determine whether coordination, strength, or practical arm use has improved after training. Such outcomes also inform the design of assistive devices and help clinicians and researchers compare personalized treatment strategies with the capabilities of the people using them.
