Summary: In golf swing analysis, traditional tools like high-speed cameras and Trackman devices are expensive and inaccessible for golfers. This research proposes using an affordable inertial motion capture system to accurately record golf swing movements, specifically focusing on distinguishing between straight and slice trajectories. The Hilbert-Huang transform (HHT) is employed to analyze the opening motion of the body's left half and the head-up motion, which are associated with a slice trajectory. The research found discernible differences in the golf swing's moment of impact between straight and slice trajectories within the instantaneous frequency domain.

Summary: This study compared the pressure distribution patterns on the foot insoles of golfers at different skill levels during the golf swing. The results showed differences in pressure distribution patterns between the left and right foot, but the patterns remained almost the same when switching between different clubs. Significant differences were also observed between professional golfers and players with medium and high handicaps in their pressure distribution patterns.

Summary: The integrated hydraulic transformer based on hydraulic common pressure rail system has a significant energy saving effect. The control of the inner loop, which is the valve-controlled hydraulic swing motor system, is closely related to the performance of the integrated hydraulic transformer. To guarantee energy-saving performance, an extended state observer-based finite-time backstepping filter control strategy is designed, considering input delay, output constraints, and actual working conditions in the inner loop system.

Summary: A constant tension control method of payload anti-swing is proposed based on the principle of linear velocity feedback. The study establishes a dynamic model of the payload anti-swing system driven by hydraulic motors and obtains the characteristics of the payload swing and cable tension through dynamic simulation. The results show that the method significantly suppresses payload swing and has a good suppression effect on asymmetric payload swing.

Summary: The study examined the relationship between movement style, center of pressure, and golf performance. The analysis of center of pressure paths of 104 amateur golfers' driver and 5-iron shots revealed that the discrete method resulted in two-cluster solutions, showcasing front-foot and reverse center of pressure styles. However, a continuous principal component analysis illustrated that these clusters were not well separated, supporting the idea of a multidimensional continuum. The analysis also found a strong correlation between center of pressure styles and handicap as well as clubhead speed, suggesting that golfers with lower handicap and faster swing speed tend to display a front-foot center of pressure style.

Summary: Motor imagery and action observation, when combined, can enhance motor performance. This study found that a combination of action observation and motor imagery performed in an asynchronous or progressive manner results in better golf putting performance and learning compared to synchronous combination. Further research is needed to determine the best way to combine action observation and motor imagery.

Summary: The study demonstrates that an external focus improves performance and learning of motor skills compared to an internal focus. Through a golf pitch shot experiment, it is found that external focus instructions enhance skill learning, increase positive affect, reduce negative affect, and improve self-efficacy. These findings support assumptions of the OPTIMAL theory and emphasize the attentional and motivational benefits of an external focus.

Summary: This study investigated physiotherapists' perceptions of prescribing ACTs for patients with bronchiectasis. The results found that physiotherapists need to consider various factors, including organizational factors, patient-related factors, and physiotherapist/profession-related factors, when making decisions regarding ACT prescription. Considering these factors can improve the personalized prescription of ACTs and promote patient adherence to treatment to improve outcomes.

Summary: The study aimed to establish the test-retest reliability of the Dyspnea Challenge in heart failure (HF) patients and compare it to chronic obstructive pulmonary disease (COPD) patients. The results showed that HF patients exhibited higher levels of average speed, gradient, oxygen uptake, and ventilation compared to COPD patients. On the other hand, COPD patients showed greater decreases in inspiratory capacity, arterial oxygen saturation, and breathing reserve.

Summary: This study found that 5-HT2 receptor activity plays a regulatory role in the behavior of motor units (MUs) in humans, affecting the firing rate and activation threshold of MUs. Inhibiting 5-HT2 receptors reduces MU discharge rate and increases derecruitment threshold, without changes in maximal voluntary contraction. This indicates that 5-HT2 receptor activity is important in regulating discharge rate of populations of spinal motoneurons during voluntary contractions.

Summary: This study used TMS to investigate the effects of muscarinic receptor blockade on muscle responses during voluntary contractions. The results showed that there were no drug-related differences in MEP area during non-fatigued or fatigued contractions. However, the duration of the TMS-evoked SP was increased by promethazine, indicating that the cholinergic system affects neural circuits associated with the SP. This study contributes to our understanding of the mechanisms behind motor side-effects caused by medications with cholinergic properties.

Summary: The purpose of this study was to examine the effects of two common methods of continuous hypoxaemia on the activity of intracortical circuits responsible for motor output inhibition and facilitation. The results showed that severe acute exposure to hypoxia for 2 hours reduced the excitability of intracortical networks and spinal circuits responsible for inhibiting motor output. This study provides insight into the potential cause of variances in motor evoked potential responses when exposed to hypoxia.

Summary: Serotonin modulates corticospinal excitability, motoneurone firing rates, and contractile strength via 5-HT2 receptors. This study investigates the effects of 5-HT2 antagonism on corticospinal and motoneuronal excitability with and without descending drive to motoneurons, showing that excitatory drive is necessary for 5-HT2 receptors to regulate motoneurone excitability but not intracortical circuits.

Summary: Recent developments in musculoskeletal modeling have focused on model customization. Personalization of the spine profile may affect estimates of spinal loading and stability. This study investigates the biomechanical consequences of changes in the spinal profile and finds that personalizing the spine profile has medium to large effects on trunk muscle forces and negligible to small effects on spinal loading and stability.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.
