Summary: The study found that a startling acoustic stimulus significantly reduced response time and EMG onset latencies for all muscles, with longer durations, higher tilt angles, and higher EMG amplitudes observed at 30 cm. Accelerometer signals in SAS trials had higher frequency content, suggesting reduced movement control. These measures could help objectively assess trunk stability in patients with neurological conditions in the future.

Summary: This study aimed to investigate the effects of robot-assisted arm training on stroke patients with unilateral spatial neglect. The results showed that this training program was feasible and safe, leading to significant improvements in neglect symptoms, motor function recovery, and social participation, but not in activities of daily living. The findings provide preliminary support for using robot-assisted arm training to remediate unilateral spatial neglect after stroke.

Summary: This study examined the impact of training with an electromechanically assisted gait training (EAGT) system, specifically the Hybrid Assistive Limb(R) (HAL), integrated with conventional rehabilitation on long-term improvements in individuals post-stroke. The findings suggest that intensive conventional gait training induced significant improvements while the integration of treadmill-based EAGT did not provide additional value in this study sample.

Summary: The study demonstrated the validity of a device-assisted approach in assessing severely impaired stroke patients' upper limb movements. Shoulder internal/external rotation was found to be a significant predictor in the clinical status, suggesting its relevance in the evaluation of stroke patients. These findings provide a promising new method for assessing severely impaired stroke patients and should be further validated in larger patient cohorts.

Summary: This study aimed to compare the effects of mirror therapy and bilateral arm training in stroke rehabilitation. It found that mirror therapy was more effective in improving upper limb motor function, and the effect can be maintained at three months follow-up.

Summary: This study developed a new method to study the modulation of stretch reflexes by combining multijoint movements with haptic environments and high-velocity perturbations. Using this method, researchers found stretch reflexes in the biceps muscle during reaching in stroke patients, but not in the control group. This study is important for understanding the impact of neurological injuries, such as spasticity after stroke, on reflex control.

Summary: This article proposes a soft wearable robot with SMA-based artificial muscle for assisting upper limb motion. Experiments and assessments show that the robot improves the range of motion and torque produced by users, but there are design issues that need further development.

Summary: The study developed robotic upper extremity therapy tasks for subacute stroke patients and found significant improvements in FMA UE, ARAT, FIM, and Visually Guided Reaching scores in the robotic therapy group post-intervention. However, only FIM and Arm Position Match scores improved in the control group over the same time period. The Kinarm therapy tasks show potential for improving outcomes in subacute stroke, but further studies are needed to confirm the benefits in a larger cohort.

Summary: An often-observed phenomenon in survivors of hemispheric stroke is the overreliance on the less-affected limb for functional tasks, despite the recovered capacity of the paretic limb. To better quantify this arm nonuse, a bimanual arm reaching test with a robot (BARTR) was developed. The BARTR is a valid, reliable, and simple instrument for assessing arm nonuse in chronic stroke survivors.

Summary: This article introduces a double-acting soft actuator that combines tendon-driven flexion and pneumatic extension of fingers using a single motor. The actuator achieves this through a smart pulley and bellow system. Kinematic and torque models are developed to analyze the actuator's performance, and experimental studies characterize its bending angle and extension torque. A prototype soft glove is fabricated to demonstrate finger flexion and extension assistance, and its performance is evaluated using electromyography signals.

Summary: This study aimed to investigate the interactive effects of proximal arm impairment and passive weight compensation on shoulder flexion performance after stroke. The results showed that shoulder flexion performance depends on proximal arm impairment and is influenced by the degree of unloading/loading provided, particularly among individuals with moderate paresis after stroke.

Summary: This study developed a sensorized glove to accurately measure joint angles of the upper limb during the performance of a functional task. It was found that stroke participants who had similar clinical scores exhibited unique patterns of joint angle variation, suggesting the importance of measuring individual joint angles in understanding changes in function after stroke.

Summary: The Armule exoskeleton was developed to mimic human natural movements for upper limb rehabilitation and showed significant improvements in clinical and kinematic metrics for stroke patients after 4 weeks of intervention. The postural synergy design concept and semi-transparent active control strategy contributed to active participation and motor control improvement.

Summary: This study aimed to determine the ability of stroke survivors and healthy individuals to generate internal and external rotation torque under different shoulder abduction and adduction loads. The results showed that patients on the paretic side performed poorly in generating internal and external rotation torque, and the effects of abduction and adduction loading were similar across all groups.

Summary: Muscle tissue undergoes changes after stroke, affecting muscle elongation and joint torque. Conventional rehabilitation lacks precise measurement tools and relies on subjective assessments of joint torques. Shear wave ultrasound elastography can provide accurate measurement of muscle mechanical properties and has the potential to be widely used in rehabilitation settings.
