Sensory Integration Processes Characterize Concussed Athletes With Balance Deficits, Bhagyashree Singh, Ingo Helmich
Exercise and Sport Studies: Faculty Publications
Impaired postural control constitutes a major symptom after mild traumatic brain injuries (mTBI/sport-related concussions (SRC)). In order to uphold cognition and behavior during pathological situations, individuals may be characterized by neuronal upregulation. Because postural control necessitates the integration of sensory information within somatosensory (/parietal) cortices, we investigated the hypothesis that athletes with ongoing symptoms after SRC are characterized by increased brain activation within these areas in order to compensate for postural deficits. Sixty-six athletes (27 ± 13 years; 50 men, 16 women) participated in the study. Twenty-two concussed athletes reported high post-concussion symptoms (PCS; symptomatic group), and 22 concussed athletes …

Does Limb Specialization In Track And Field Introduce Asymmetry In Dynamic Stability?, Aaron X. Jones
Does Limb Specialization In Track And Field Introduce Asymmetry In Dynamic Stability?, Aaron X. Jones
Master's Theses
Time to stabilization (TTS) represents the time it takes for a person to become still after a hop landing. Lower times suggest greater dynamic stability. Whereas leg dominance (preference) does not seem to have a significant impact on TTS performance in the general healthy populations, limb specialization in sport may introduce asymmetry. This study compares TTS following forward hops in healthy male controls (N = 19) to varsity DIII Track & Field athletes (N = 20). Groups were equal for height, but the athlete group’s average limb length (106.7 ± 5.5 cm) was greater than the control group (101.5 ± …
