Summary: This study investigates the force distribution during stable thumb-index finger power-grasp of fruit. Significant differences were found in the percentage contribution of normal forces among power-grasp regions, fruit size, power-grasp postures, and centre of mass. The contribution of normal forces on the distal phalanx of the thumb and index finger was larger than other regions. The longitudinal power-grasp posture was found to be more efficient than the horizontal power-grasp. The distribution of normal forces on each grasping region should be adjusted based on the centre of mass location.

Summary: The study found that over 40% of patients still use treatments for thumb carpometacarpal arthritis surgery 1 to 4 years after the surgery, with 22% using multiple treatments. The use of any treatment is associated with significantly worse patient-reported outcomes for function and pain.

Summary: Sensor-based devices can provide a comprehensive approach to quantifying grip strength during sustained contractions. This study investigated the reliability and concurrent validity of measures of maximal tactile pressures and forces using a TactArray device in people with stroke. The study found that the device demonstrated satisfactory reliability and concurrent validity for measures of maximal tactile pressures.

Summary: Stroke patients vary in outcomes, with some showing natural recovery proportional to initial impairment. Predicting individual recovery potential through structural connectome analysis, especially in severely impaired patients, allows for personalized neuro-rehabilitation decisions. Understanding neuronal network mechanisms underlying recovery is crucial for predicting and facilitating stroke rehabilitation.

Summary: Most individuals with aphasia after stroke recover to some extent in the first year, and the recovery process is partially dependent on lesion location and extent. This study aims to provide a comprehensive description of patterns of recovery from aphasia in the first year after stroke. It found that lesion location and extent, as well as different language domains, have an impact on aphasia recovery.

Summary: This study aimed to quantitatively evaluate wrist spasticity in stroke survivors using a custom motor-controlled device and investigate whether the measured values could reflect the spastic state of the flexor muscles. The results showed that the damping force and normalized value increased significantly with velocity, and there were correlations between MAS scores and damping parameters.

Summary: After a stroke, neural plasticity mechanisms can be activated for significant recovery. Rehabilitation therapies aim to restore tissue and reorganize neural connections. New technologies such as brain-computer interfaces, robot-assisted and virtual reality therapies, brain stimulation, and cell therapies have emerged as promising options for better functional outcomes.

Summary: This study aimed to explore the whole-brain dynamic functional connectivity patterns in acute ischemic stroke (AIS) patients and their relation to stroke severity. The research identified differences in dynamic connectivity configurations between patients with different levels of stroke severity and highlighted the importance of dynamic connectivity involving default mode network components for recovery in the first 3 months poststroke.

Summary: The study investigated the relationship between poststroke brain functions and functional recovery with the rich-club organization of the structural brain network. It found that specific rich-club regions remained stable during stroke recovery and network properties related to the communication cost ratio and density ratio of connections played a role in poststroke brain functions. Additionally, higher normalized rich club coefficients and shorter local connections within a week after stroke were correlated with better recovery of motor functions and activities of daily living.

Summary: The high incidence of ischemic stroke and lack of effective neuroprotective drugs have led to the need for novel therapies in stroke recovery. VGF, a neurosecretory protein, has been identified as important for stroke recovery. Knockout mice lacking VGF demonstrated impaired recovery and reduced migration of immature neurons, which could be rescued by exogenous delivery of VGF peptides.

Summary: A study has found that the recovery of cognitive function after stroke is related to neurotransmitter systems, learning-related networks, and brain regions that can adapt to demand. The status of the cholinergic basal forebrain, fornix, and hippocampal subfields predicted improvement in long-term memory performance. These findings provide important information for personalized therapeutic strategies after stroke.

Summary: Ischemic damage in brain tissue leads to plastic changes in cell-to-cell interactions, influencing a wide range of molecular and structural interactions. Understanding and manipulating these intercellular connections is crucial for post-stroke neurorehabilitation.

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 study developed a statistical framework to analyze recovery patterns in stroke patients with different levels of initial impairment, finding that severely affected patients recovered more as their impairment decreased, while non-severely affected patients recovered more as their initial impairment increased. The study's out-of-sample prediction performance was R-2=63.5% (95% CI=51.4% to 75.5%), providing evidence for the benefit of simultaneously modeling recovery of severely-to-non-severely impaired patients and demonstrating shared and distinct recovery patterns.

Summary: This study aimed to develop methods for assessing corticospinal divergence and muscle coupling using transcranial magnetic stimulation (TMS). The researchers found that the number of muscles responding to TMS and the degree of coactivation increased with intensity, while correlations of MEP amplitudes varied among different muscle pairs, possibly quantifying different levels of muscle coupling.

Summary: This study found that the use of an algorithm with clinical measures only is better than chance alone at predicting the upper limb capacity at 3 months post-stroke. The moderate to high values of sensitivity, specificity, positive predictive value, and negative predictive value demonstrate the clinical utility of the algorithm within healthcare settings in the US.

Summary: The study aimed to investigate the modulation of corticospinal pathway on spinal reflex excitability. The results showed that subthreshold TMS pulses could partially restore the H-reflex when it was almost completely suppressed by lower extremity vibration. This suggests that the disinhibition of the H-reflex by corticospinal signals may play a role in the control of voluntary movement.

Summary: This study explored the feasibility of using bilateral wrist accelerometers to measure upper limb activity in children with autism. The findings showed that movement intensity and complexity were moderately related to motor coordination. These preliminary results suggest that wearable sensors may be an effective tool for assessing motor characteristics that impact adaptive function in children with autism.
