Several studies in adults having observed the effect of eye movements on postural control provided contradictory results. In the present study, we explored the effect of various oculomotor tasks on postural control and the effect of different postural tasks on eye movements in eleven children (7.8 ± 0.5 years) and nine adults (30.4 ± 6.3 years). To vary the difficulty of the oculomotor task, three conditions were tested: fixation, prosaccades (reactive saccades made toward the target) and antisaccades (voluntary saccades made in the direction opposite to the visual target). To vary the difficulty of postural control, two postural tasks were tested: Standard Romberg (SR) and Tandem Romberg (TR). Postural difficulty did not affect oculomotor behavior, except by lengthening adults' latencies in the prosaccade task. For both groups, postural control was altered in the antisaccade task as compared to fixation and prosaccade tasks. Moreover, a ceiling effect was found in the more complex postural task. This study highlighted a cortical interference between oculomotor and postural control systems.

Stroke significantly contributes to long-term disability, one of the problems is with impaired balance control, increasing the risk of falls. The risk of falls may be mitigated using reactive balance training (RBT) which has been shown to effectively reduce fall risk by enhancing reactive stepping following repeated balance perturbations. However, the optimal RBT intensity for people with chronic stroke remains unknown.

Background: Postural balance is impaired in adults with asthma; however, this remains poorly understood in older people with asthma.
Objective: To assess postural balance and the incidence of falls in older individuals with moderate to severe asthma.
Methods: A controlled cross-sectional study with follow-up included individuals aged 65 to 80 years (asthma group,AG; n = 26) and without asthma (control group,CG; n = 27).

Purpose: Total knee arthroplasty (TKA) is associated with acute postoperative effects that increase the risk of falls. These effects differ between the medial parapatellar (PP) and mid-vastus (MV) surgical techniques but have not been evaluated in terms of postural sway complexity. Loss of this complexity leads to increased randomness in the center of pressure and higher fall risk.

Objective: This study aims to investigate whether alterations in the lower extremity kinematics, kinetics, and muscle activity of individuals with chronic ankle instability (CAI) occur during landing with expected and unexpected inversion perturbations.
Methodology: PubMed, Embase, Cochrane Library, Web of Science, and Scopus databases were searched for relevant studies up to November 30, 2024. Comparative studies investigating the characteristics of lower extremity kinematics, kinetics, and muscle activity in individuals with CAI compared with healthy controls were included.

The ability to navigate through one's environment is crucial for maintaining independence in daily life and depends on complex cognitive and motor functions that are vulnerable to decline in persons with Multiple Sclerosis (MS). While previous research suggests a role for mobility in the physical act of navigation, it remains unclear to what extent mobility impairment and perceptions of mobility constraints may modify wayfinding and the recall of environment details in support of successful navigation. Therefore, this study examined the relations among clinical mobility function, concern about falling, and recall of environment details in a clinical sample of MS.
