“…Lower OSI scores imply less variability of the CoP, indicating better postural control 19 . Our results support previous studies that showed better balance with visual feedback, 9,10,12 indicating beneficial effect of the additional sensory input for precise postural adjustments. Notably, there were no significant differences between groups with either VF or NVF.…”

“…Larger frontal theta values are interpreted as an increased focused attention 13 . Thus, the increased frontal theta power with the addition of visual feedback may indicate that repetitive and constant visual stimuli induced a greater amount of neurocognitive processing in the prefrontal cortex, requiring more attention for instantaneous postural adjustment 9,10,12 …”

“…This may explain why the occipital alpha‐2 power remained consistent, with no significant differences between NVF and VF in both ACLR and CONT groups. It was expected that there would be an increased cortical activation in the occipital cortex with VF; however, ACLR participants could have similar activation in the NVF condition possibly due to environmental visual stimulus around the room providing the participant perception of spatial orientation even without the cursor 10 . Additionally, the group‐by‐condition interaction effect for parietal alpha‐2 power was statistically significant, but pairwise comparison results were not significant.…”

“…Improved postural control has been shown with addition of visual feedback for both healthy older adults and those with balance deficits after a stroke 8 . Additionally, improved single‐leg balance has been also observed following ankle and knee injuries with additional visual feedback, 9,10 as the visual system allows simultaneous postural adjustment. As the brain simultaneously integrates and processes sensory inputs related to body posture from both the somatosensory and visual systems, additional visual feedback may assist to prepare and modify body posture to maintain balance 9 …”

Purpose Poor balance in anterior cruciate ligament reconstruction (ACLR) patients indicates neuromuscular control (NMC) deficits, which may be associated with altered cortical activation in the brain. This study examines cortical activation patterns in ACLR patients compared with healthy controls during a single‐leg balance task with and without visual feedback. Methods Thirteen ACLR patients (ACLR, 23.38 ± 3.38 years) and thirteen healthy controls (CONT, 23.54 ± 3.48 years) performed a single‐leg balance task with both visual feedback (VF) and non‐visual feedback (NVF) with continuous electroencephalograph (EEG) monitoring. Knee function was also evaluated through a subjective assessment survey. Results Frontal theta power was significantly higher with VF compared to NVF. Significant group‐by‐condition interaction effect for parietal alpha‐2 revealed that the CONT group had increased activation with VF, whereas the ACLR group had increased activation with NVF. A negative correlation emerged between KOS‐ADL in the ACLR group with parietal alpha‐2 during NVF and occipital alpha‐2 during VF. Conclusion ACLR patients had comparable single‐leg balance to healthy controls, yet different cortical activation patterns emerged on EEG. ACLR patients with better knee function showed greater cortical activation in the somatosensory and visual cortices. Further research should consider these cortical changes in restoration of balance after ACLR.

“…Balance ability refers to the control that coordinates the body continuously in relation to the environment (Tracey et al, 2012), which was a complex of static and dynamic balance. A degraded balance capability frequently leads to instability of the ankle joint (Mattacola and Dwyer, 2002;Nam et al, 2018). Consequently, balance exercise training is often prescribed as a treatment for improving postural control, proprioception, balance, and ankle joint stability (Ross and Guskiewicz, 2006;Wortmann and Docherty, 2013;Nam et al, 2018).…”

Context: Appropriate training without risk of injury is a critical concern for athletes. Remodeled bicycle pedal training with multi-directional challenges may be effective in improving the balance performance of athletes with functional ankle instability (FAI). Objective: To evaluate the effects of 6-week modified bicycle pedal training on the balance ability and proprioception of athletes with FAI. Design: Randomized controlled trial. Setting: University motion analysis laboratory. Participants: Fourteen healthy athletes (healthy group) and twenty-six athletes with FAI and an age of 18 to 30 years old. The participants with FAI were randomly distributed to two groups, designated as the training group (AI-T group) and non-training group (AI-NT group), respectively. The athletes in the AI-T group received 6-week remodeled bicycle pedal training, while those in the AI-NT group received no intervention at all. Intervention: A 6-week training using modified bicycle pedal capable of moving freely during loading cycle vs no intervention. Main Outcome Measures: The passive ankle joint position sense (JPS) in four angles and the center of pressure (COP) parameters were analyzed during single-leg standing with and without vision, respectively. Results: A 6-week remodeled pedal training: (1) significantly improved the passive JPS of ankle in all directions (P < 0.05); (2) reduced the excursion of the COP in the mediallateral (ML) direction (p < 0.05), the velocity of the COP in the ML direction (p < 0.05), and the RMS of the COP in the ML direction (P < 0.05) during single-leg standing both with and without vision. Conclusion: The remodeled bicycle pedal training improved the passive JPS and reduced the postural sway in single-leg standing both with and without vision. Therefore, remodeled bicycle pedal training can be considered for inclusion in rehabilitation programs for athletes with FAI to restore the proprioception and balance ability.

Background: Balance disorders are among the most frequent reasons for consultation and referral to specialist care. Osteopathic Manipulative Treatment (OMT) can influence the proprioceptive system by inducing alterations in the proprioceptive stimuli, hence affecting postural control. Objective: The present systematic review aimed to explore the effects of OMT in managing patients with vertigo and balance disorders. Methods: MEDLINE (PubMed), ScienceDirect, and Google Scholar were searched. Clinical trials and prospective observational studies were considered. Only studies that considered OMT as the main intervention, provided alone or combined with other interventions, were included. The methodological quality of the evidence was assessed with a modified version of the Newcastle-Ottawa Scale. Results: Five studies that enrolled a total of 114 subjects met our inclusion criteria. Overall, it has been observed that there is a positive effect on balance disorders through different outcomes in all of the included studies. Only two studies (9 subjects) mentioned low to moderate adverse events after OMT. Conclusions: OMT showed weak positive effects on balance function, encouraging the connection of conventional medicine and evidence-based complementary medicine for integrative clinical practice and interprofessional work. However, full-sized adequately powered randomized trials are required to determine the effectiveness of OMT for vertigo and balance disorders.
