Summary: This study examined the impairment of selecting, preparing, and initiating gait in individuals with Parkinson's disease (PD) and freezing of gait (FOG) using a startling acoustic stimulus paradigm. The results showed that a startling acoustic stimulus led to the rapid initiation of anticipatory postural adjustments in both simple and choice reaction time tasks in all groups. It was concluded that the neural capacity to prepare gait initiation remains intact in PD individuals with and without FOG, and the retained ability to prepare anticipatory postural adjustments may explain the effectiveness of external sensory cues in facilitating gait initiation in individuals with PD and FOG.

Summary: The aim of this study was to investigate changes in muscle synergies prior to gait initiation and the effects of gaze shift in Parkinson's disease (PD) patients. The study found that PD patients showed impaired stability of the center of pressure and decreased adjustment during gait initiation compared to the control groups. The stability indices and anticipatory synergy adjustment (ASA) may be useful for monitoring pre-clinical gait disorders and the emergence of freezing of gait in PD.

Summary: The study showed that reliability of gait initiation varies across outcomes but is similar for healthy elderly and individuals with Parkinson's disease with Freezing of Gait, under single and dual task conditions. Anticipatory postural adjustments and first step range of motion are the most reliable outcomes, while APA duration and latency are the least reliable. Future studies should consider conducting multiple trials of gait initiation depending on the specific outcome of interest to improve reliability.

Summary: This study aims to validate the performance of an ultra-light sensor in measuring anticipatory postural adjustments (APAs) during step initiation, compared to a smartphone and a kinematic system. The results show that the temporal measurements obtained from the sensor and smartphone have high correlation with the kinematic system. However, caution should be exercised when using the ultra-light sensor for amplitude measurements, as further research is needed.

Summary: This study compared the ability of young and older participants to generate anticipatory postural adjustments (APAs) in response to proprioceptive perturbation before gait initiation. Results showed that young adults actively adjusted their postural responses to altered proprioception from lower leg muscles, while older adults were unable to adapt.

Summary: This study investigated the differences in characteristics of patients with idiopathic Parkinson's disease (IPD) who exhibit freezing of gait (FOG) and examined the effectiveness of visual cueing using laser shoes. The results showed that patients with lower self-reported FOG severity scores, higher dopamine active transporter availability in specific regions of the brain, and shorter duration of FOG episodes without cueing responded better to visual cueing. These findings have important implications for identifying patients who may benefit from visual cueing and the early diagnosis of FOG in IPD patients.

Summary: This study aimed to investigate reduced anticipatory postural adjustments during gait initiation in post-stroke hemiplegic patients through measuring the center of pressure. The results showed that the latency and magnitude of center of pressure displacement peak for the paretic leg were significantly different compared to controls, and correlated with clinical measures of motor dysfunction and postural balance.

Summary: The difficulty in assessing FOG and the variety of existing cues make it challenging to determine the most appropriate cueing modality and targets for personalized treatments for FOG. This systematic review aimed to determine the effectiveness of cues in reducing FOG and improving gait parameters, and whether medication state affects cue-related results.

Summary: This study aimed to test the feasibility of center of pressure (COP) displacement during gait initiation as a measure of anticipatory postural adjustment (APA) in Parkinson's disease (PD) patients. The results showed that PD patients with a history of freezing of gait (FOG) had a favorable response of APAs to dopaminergic therapy. The COP parameters could be surrogate markers to assess PD patients with FOG history.

Summary: Patients with Parkinson's disease and freezing of gait have significant deficits in dynamic balance control, characterized by hypokinetic weight-shift amplitudes. Medication, particularly levodopa, can improve mediolateral weight-shifting in patients with freezing of gait, along with decreasing the freezing ratio. Further research is needed to investigate whether training can further ameliorate weight-shifting and freezing severity in these patients.

Summary: The study found that applying auditory cues based on individual's phi-rhythm can improve gait patterns in people with Parkinson's disease, such as parameters like stride length, walking speed, and toe clearance. Therefore, phi-rhythm appears to be an effective cue to enhance gait in individuals with PD.

Summary: This study aimed to assess the kicking competence of individuals with Down syndrome (IDS). The results showed that IDS had lower motor competence and lower angular velocities compared to typically developed individuals (ITD). The lower trunk angular velocity in IDS may limit the ability to perform the proximal-to-distal sequencing commonly observed in kicking and generate high shank angular velocity upon ball impact. This could be attributed to orthopaedic features of the pelvic girdle and poorer neuromuscular control of core muscles.

Summary: This study evaluated the current literature on the reactive recovery responses between over-ground and split-belt treadmill trips and slips, as well as the effect of aging on these responses. The results showed that although both treadmill and over-ground perturbations destabilize the center of mass similarly, the recovery responses to these perturbations were more consistent on treadmills. However, treadmills may be limited in investigating the variety of aging impairments on perturbation recovery responses due to the difficulties older adults face in perturbation recovery scaling.

Summary: Idiopathic toe walking (ITW) is a gait deviation characterized by forefoot contact with the ground and excessive ankle plantarflexion over the entire gait cycle observed in otherwise-typical developing children. Clinical evaluation of ITW is usually hindered by children adopting a typical walking pattern instead of a toe walk. Therefore, measuring gait in a more ecological environment may be crucial in this population.

Summary: This study aims to define a methodology using smartphone inertial measurement units to measure standing long jump (SLJ) easily. A group of 114 trained young participants performed the instrumented SLJ task and a subset of predictors of SLJ length was identified using Lasso regression and optimized machine learning architectures. The proposed configuration achieved an estimate of SLJ length with a RMSE of 0.122m and Kendall's t < 0.1 using a Gaussian Process Regression model. This study demonstrates the feasibility of using low-cost smartphone sensors for automatic and objective SLJ performance estimate in ecological settings.

Summary: The study showed that age-related changes in rhythmic reproduction ability are influenced by the complexity of the adopted movement task. Older adults demonstrated reduced accuracy and tendency to speed up beats reproduction, especially in more complex tasks like walking. Further research should examine how specific rhythmic training with progressive movement task complexity can help counteract this age-related decline.

Summary: Research has shown that spontaneous visual coupling supports frequency entrainment, phase attraction, and intermittent interpersonal coordination during the switch from a novision (NV) to vision (V) context among co-actors. The experiments demonstrate that similar self-paced frequencies result from same amplitude movements, while different amplitudes lead to disparate frequencies. In experiment 1, co-actors were instructed to maintain amplitude without explicit instructions for coordination, which limited frequency and phase entrainment in the V context. In experiment 2, co-actors were instructed to maintain amplitude and intentionally coordinate together, resulting in significant frequency modulations and the production of various stable relative phase patterns.
