These measures assessed execution and directional control, respectively. Results showed that peak mallet heights increased from notes 1-4 during crescendos and decreased over the same range during decrescendos, coinciding with increased and decreased peak hand velocity. During crescendos, the left mallet and hand were consistently elevated higher above the playing surface than the right. Within the right hand effects were localized to the velocity domain. For upstrokes, hand velocity was lower in crescendos versus decrescendos, while velocity was higher for downstrokes in crescendos. These findings indicate distinct motor control strategies contributing to the directional control and execution of sound-producing movements, emphasizing limb-specific mechanisms that could inform percussion pedagogy.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"827-842"},"PeriodicalIF":1.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145543800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kinematic data were acquired using a Motion Monitor unit with a 3D motion tracking electromagnetic system (Liberty, Polhemus). Scapular, upper limb, and head were recorded during forward reaching tasks (hand on overhead ball and hand to head) and a backward reaching task (hand on the back pocket). The study revealed reduced shoulder flexion and extension in children with NBPP during hand on ball and on the back pocket tasks compared to unaffected controls. Limited elbow flexion was also observed in children with NBPP during the hand on ball and hand on the head tasks. During the hand to head task, children with NBPP presented increased head flexion compared to unaffected controls. Scapular kinematics analysis showed increased posterior tilt in children with NBPP during forward reaching (the hand on ball and hand to head tasks). In the backward reaching task (hand on the back pocket), the NBPP group exhibited reduced scapular external rotation compared to unaffected controls. These findings indicate distinct kinematics in the scapula, shoulder, elbow, and head during reaching tasks for children with NBPP compared to controls. Furthermore, different execution speeds did not alter the kinematic differences between the groups.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"107-117"},"PeriodicalIF":1.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142569894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These changes were sometimes correlated with corticospinal effects, suggesting a link between VIB-induced plasticity and clinical improvements.

Twenty-two healthy participants engaged in eight postural control tasks: standing/crouching (Posture) × eyes opened/eyes closed (Vision) × light touch/no touch (Touch). The total trajectory length and root-mean-square of the center of pressure in the anterior-posterior and medio-lateral directions were analyzed. Light touch reduced the sway of the center of pressure in both the standing and crouching postures, particularly in the anterior-posterior direction. Furthermore, the touch effect on the sway of the center of pressure varied between the standing and crouching postures. Consistent effects were observed in the anterior-posterior direction, but differing effects were observed in the medio-lateral direction. These results indicate that somatosensory input from the fingertip reduces postural sway in both directions in a crouched posture. Variations of the center of pressure disturbances in the medio-lateral direction could originate from differences in postural strategies involving the ankle and hip joints between bipedal standing and crouching positions.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"260-268"},"PeriodicalIF":1.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143494350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, less is known about the influence of the nature of visual feedback on torque variability. The present study aimed to investigate the effect of two different feedback natures, one from the angular position and the other from the torque produced, on the magnitude and temporal structure of torque variability during submaximal hold isometric tasks. Twenty healthy and young participants performed a knee extension isometric task, consisting in sustaining an applied resistance equivalent to 40% of their Maximal Voluntary Isometric Contraction for 30 s with visual feedback from angular position (Hangle) and with visual feedback from torque (Htorque). The magnitude of torque variability was calculated through the coefficient of variation. Sample Entropy was used to analyze the temporal structure of torque fluctuations, i.e., torque complexity. We observed no significant differences between conditions (Hangle vs Htorque) in both magnitude (p = 0.117) and the temporal structure of torque fluctuations (p = 0.940). Our results demonstrated that torque regulation seems not to be affected by the nature of the visual feedback during hold submaximal isometric tasks, suggesting a participation of sensorimotor system due to the nature of the task. Researchers should take this into account to take methodological decisions when using hold submaximal isometric tasks to investigate possible changes in motor control.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"269-277"},"PeriodicalIF":1.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143558529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the mechanisms to induce a cutaneous afferent volley have been limited to electrical stimulation, it remains unknown if mechanical stimuli can modulate stretch reflex (SR) excitability. The purpose of this study was to examine the effect of adding cutaneous inputs on modulating the SR during perturbed gait termination. Thirty young adults completed walking trials when a platform unexpectedly tilted 10 degrees anteriorly or posteriorly, inducing a tibialis anterior (TA) or medial gastrocnemius (MG) short-latency reflex. The SR latency, the peak SR amplitude, and the total SR amplitude of the agonist burst, were compared between the stretched muscle and cutaneous facilitation. Statistically significant interactions were observed between the stretched muscle and cutaneous facilitation on the SR peak and SR burst. More notably, texture resulted in a consistent expression on the TA SR magnitude, without a similar effect in MG. Despite confirming the ability of cutaneous afferent facilitation on modulating spinal interneuronal circuitry, participant variability in response to texture highlights the importance of focusing on individual participant results when studying the effects of cutaneous facilitation on modulating spinal motorneuron excitability.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"311-320"},"PeriodicalIF":1.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143568762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants performed a novel snare drum excerpt while motion capture measured upper-limb movements prior to and following training. Temporal errors were also computed by comparing note onsets to the ideal timing specified by a metronome. Results revealed that temporal errors were lower in post- vs. pre-training performances, irrespective of group. In both groups, post-test performances were characterized by a higher average position of the mallets above the playing surface and greater hand velocity vs. pre-training performances.

While often attributed to postural stiffening, such changes may also reflect a shift toward more automatic control. However, most height-related studies use a feet-parallel stance, which may not be generalized to more constrained foot positions like semi-tandem, which are often encountered in real-world height situations. This study investigated the effects of acute virtual height exposure on postural control in a semi-tandem stance. Twenty young adults stood on a force platform under three conditions: (1) no VR, (2) VR sidewalk at ground level, and (3) VR elevated plank. Each participant completed six 60-second trials per condition. Repeated-measures ANOVAs revealed that wearing the VR headset alone affected postural control, with further changes under height exposure. Height was associated with increased COP frequency and irregularity, suggesting more automatic control. However, due to biomechanical constraints, the semi-tandem stance may have influenced postural strategies, resulting in increased COP variability. These findings support the use of VR to study postural threat and highlight the role of foot position in postural adaptations.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"664-672"},"PeriodicalIF":1.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144818059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Young adults (n = 24; 15 female; 24.9 ± 4.5 years) completed walking turns to goals located 60 degrees left or right of their walking path. In some trials, heel contact with a force plate triggered appearance of an arrow on the same side (congruent), opposite side (incongruent) or in the middle (neutral) of a screen. To determine impact of different biomechanical demands for task execution, researchers specified which foot to initiate gait for each trial; this ensured visual cues were triggered either by the same limb as the turn direction (ipsilateral) or opposite (contralateral). We observed that head and trunk yaw motion was initiated earlier and with greater relative rotation magnitude for incongruent visual cues. Step width adaptations were also observed for both step patterns when responding to incongruent visual cues.
