Corticospinal Adaptation to Short-Term Horizontal Balance Perturbation Training [PDF]

Brain Sciences, 2023
Sensorimotor training and strength training can improve balance control. Currently, little is known about how repeated balance perturbation training affects balance performance and its neural mechanisms.

Test–retest reliability of cortico-spinal measurements in the rectus femoris at different contraction levels [PDF]

Frontiers in Neuroscience, 2023
Single-pulse Transcranial Magnetic Stimulation (TMS) and, very recently, lumbar stimulation (LS) have been used to measure cortico-spinal excitability from various interventions using maximal or submaximal contractions in the lower limbs.

The Effects of Cold Water Immersion on the Recovery of Drop Jump Performance and Mechanics: A Pilot Study in Under-20 Soccer Players [PDF]

Frontiers in Sports and Active Living, 2020
Cold water immersion (CWI) is a popular method used for enhancing recovery from exercise. However, the efficacy of this approach is inconclusive and studies investigating variables contributing to overall performance are scarce. Additionally, few studies

Reliability of transcranial magnetic stimulation and H-reflex measurement during balance perturbation tasks [PDF]

Frontiers in Physiology, 2022
Following ankle movement, posterior balance perturbation evokes short- (SLR ∼30–50 ms), medium- (MLR ∼50–60 ms), and long-latency responses (LLR ∼70–90 ms) in soleus muscle before voluntary muscle contraction.

Comparative assessment of heel rise detection for consistent gait phase separation [PDF]

Heliyon
Background: Accurate identification of gait events is crucial to reliable gait analysis. Heel rise, a key event marking the transition from mid-stance to terminal stance, poses challenges in precise detection due to its gradual nature.

A comparative analysis of non-communicable disease risk among adolescents aged 12 to 18 in the Eastern Cape, South Africa, with regard to sex, school quintiles, and perceived stress [PDF]

Frontiers in Public Health
BackgroundNon-communicable diseases (NCDs) are a growing concern in low- and middle-income countries, especially among adolescents. Recent data indicate a rise in NCD cases within this group. Despite the increasing prevalence of NCD risk factors, limited

Revising the stretch reflex threshold method to measure stretch hyperreflexia in cerebral palsy [PDF]

Frontiers in Bioengineering and Biotechnology, 2022
Hyper-resistance is an increased resistance to passive muscle stretch, a common feature in neurological disorders. Stretch hyperreflexia, an exaggerated stretch reflex response, is the neural velocity-dependent component of hyper-resistance, and has been

Medial Gastrocnemius Muscle Architecture Is Altered After Exhaustive Stretch-Shortening Cycle Exercise [PDF]

Frontiers in Physiology, 2019
Muscle architecture is an important component of muscle function, and recent studies have shown changes in muscle architecture with fatigue. The stretch-shortening cycle is a natural way to study human locomotion, but little is known about how muscle ...
