Special Issue Information

Dear Colleagues,

The brain serves a vital role in orchestrating movement, and one of its most crucial functions is controlling posture to maintain an upright body position. In recent decades, extensive research efforts have been dedicated to unraveling the intricate neural processes that underlie postural control mechanisms.

This Special Issue is dedicated to advancing our understanding of human movement control, with a specific emphasis on postural control. While we welcome research contributions across the spectrum of human movement, we extend a special invitation to studies that explore postural control from a movement analysis perspective. The objective of this Special Issue is to explore the intricate intersection between neuroscience and human movement, offering insights into fundamental scientific inquiries as well as practical applications in therapy and training. For instance, we aim to unravel questions such as the following: How do neural mechanisms or adaptations within the neural system influence the nuances of postural movements? When discrepancies or alterations in these movement patterns emerge, what are the ramifications for the motor control models that are hypothesized to govern postural control? Furthermore, how can the principles of motor control be harnessed to enhance therapeutic interventions?

Researchers and experts are invited to contribute their insights, methodologies, and findings to shed light on these critical questions. Together, let us deepen our knowledge of the intricate relationship between the brain, postural control, and human movement, pushing the boundaries of our understanding and paving the way for innovative approaches in the field.

Purpose: Persons with multiple sclerosis (MS) experience changes in balance, such as poor and reactive stepping, as well as altered fall-related psychological factors, such as increased concern about falling and feared consequences about falling. Such concerns and fear may relate to and influence mobility. However, these relations are poorly understood in people with MS. This study aimed to investigate the relation between reactive stepping performance and fall-related psychological factors, as well as to assess how these relations differ between individuals who have and have not fallen. Methods: In a single session, participants completed measures regarding fall-related psychological factors (balance confidence, concern about falling, and feared consequences of falling) and completed reactive stepping tasks. Following the visit, participants completed weekly surveys for 3 months to report their falls. Spearman rho correlations were computed to examine associations between participants’ reactive stepping performance and their fall-related concerns, confidence, and consequences, with a stratified analysis to compare these associations between fallers and non-fallers. Results: 44 individuals with MS participated in our study, with 27 individuals experiencing 0 falls (non-fallers) and 17 individuals experiencing at least 1 fall (fallers) in the 3-month follow-up period. Better reactive stepping performance was correlated with fewer concerns, greater confidence, and lower feared consequences related to falling. The stratified analysis revealed a greater number of significant associations for non-fallers than fallers, although the small sample of fallers reduced our ability to detect a relationship in this group. Conclusions: Reactive stepping was associated with fall-related psychological factors. Interventions targeting reactive stepping may be beneficial in enhancing fall-related psychological well-being in the MS community. Full article

Bilateral Deficits in Dynamic Postural Stability in Females Persist Years after Unilateral ACL Injury and Are Modulated by the Match between Injury Side and Leg Dominance

Previous research has documented brain plasticity after an anterior cruciate ligament (ACL) tear and suggests that these neural adaptations contribute to poorer motor control. Since both brain hemispheres show adaptations, we hypothesized that reduced dynamic stability occurs not only in the injured, but also the contralateral, uninjured leg. Further, given brain hemispheric specialization’s impact on motor coordination, we hypothesized the need to consider the injury side. A total of 41 female athletes and 18 controls performed single-leg jump-landings. Dynamic postural stability was measured as time-to-stabilization (TTS). We found reduced medio-lateral dynamic stability for the ACL injured leg (p = 0.006) with a similar trend for the contralateral leg (p = 0.050) compared to the control group. However, when distinguishing between injuries to the dominant and non-dominant legs, we found increased medio-lateral TTS only if the injury had occurred on the dominant side where landings on injured (p = 0.006) and contralateral (p = 0.036) legs required increased TTS. Assessments of dynamic stability, e.g., in the context of return-to-sport, should consider the injury side and compare results not only between the injured and the contralateral leg, but also to uninjured controls. Future research should not pool data from the dominant-leg ACL with non-dominant-leg ACL injuries when assessing post-injury motor performance. Full article
