Studies indicate that brain response during proprioceptive tasks predominates in the right hemisphere. A hemisphere lateralization for proprioception may help to explain findings right-limb dominant individuals perform position matching better with non-dominant left side. Evidence proprioception-related and side preference is, however, limited based mainly on studies of upper limbs. Establishing associated acuity lower limbs asymptomatic could be useful understanding influence neurological...

Knee proprioception deficits and neuroplasticity have been indicated following injury to the anterior cruciate ligament (ACL). Evidence is, however, scarce regarding brain response knee tasks impact of ACL injury. This study aimed identify regions associated with proprioceptive sense joint position at whether related individuals reconstruction differed from that asymptomatic controls. Twenty-one persons unilateral (mean 23 months post-surgery) either right ( n = 10) or left 11) knee, as well...

The evolving use of sensors to objectively assess movements is a potentially valuable addition clinical assessments. We have developed new self-test application prototype, MyBalance, in the context fall prevention aimed for by older adults order independently balance and functional leg strength. objective this study was investigate concurrent validity between instruments variables collected with smartphone. prototype has two test procedures: static standing positions, strength performed as...

Abstract1. To investigate whether toxicity tests on HeLa cells were predictive of eye irritancy, 18 compounds known irritancy and in vitro cytotoxicity tested the MIT-24 system.2. The results correlated well with as determined by Draize test rabbits for 16 substances, but failed to detect high 1-heptanol allyl alcohol, both which cytotoxic other cellular systems.

This study evaluated motor control recovery at different times following anterior cruciate ligament reconstruction (ACLR) by investigating lower-limb spatiotemporal symmetry during stair descent performances. We used a cross-sectional design to compare asymptomatic athletes (Controls, n = 18) with group of people ACLR (n 49) divided into three time-from-ACLR subgroups (Early: <6 months, 17; Mid: 6–18 16; Late: ≥18 16). evaluated: "temporal symmetry" the stance subphases (single-support,...

Abstract The ability to perform individual finger movements, highly important in daily activities, involves visual monitoring and proprioception. We investigated the influence of vision on spatial temporal control independent for dominant non-dominant hand relation sex. Twenty-six healthy middle-aged old adults (M age = 61 years; range 46–79 females n 13) participated. Participants performed cyclic flexion–extension movements at metacarpophalangeal joint one a time while keeping other...

Sensorimotor deficits, particularly proprioceptive, are often reported following rupture of the anterior cruciate ligament (ACL). High secondary injury rates and long-term negative consequences suggest that these deficits not properly identified using current assessment methods. We explored a novel obstacle clearance test to evaluate sensorimotor control in individuals ACL reconstruction (ACLR) rehabilitation. Thirty-seven post-ACLR individuals, 23 nonathletic asymptomatic controls (CTRL),...

Musculoskeletal trauma often leads to lasting psychological impacts stemming from concerns of future injuries. Often referred as kinesiophobia or re-injury anxiety, such have been shown hinder return physical activity and are believed increase the risk for secondary Screening anxiety is currently restricted subjective questionnaires, which prone self-report bias. We introduce a novel approach objectively identify electrocortical associated with threat destabilising perturbations. aimed...

Nineteen isomeric chlorophenols were tested in the MIT-24 system for their toxicity to HeLa cells. Cytotoxicity varied between 0.37 and 900mg/L generally increased proportion number of chlorine substituents partition coefficient. In addition, ortho chlorination decreased toxicity, while meta had opposite effect. A good correlation was found cell data on bacterial substances, indicating similarity mechanism action. Acute lethal dosage rats did not correlate well with cytotoxicity data, spite...

Abstract Knee proprioception deficits and neuroplasticity have been indicated following injury to the anterior cruciate ligament (ACL). Evidence is however scarce regarding brain response knee tasks impact of ACL injury. Twenty-one persons with unilateral reconstruction (mean 23 months post-surgery) either right (n = 10) or left 11) knee, as well 19 controls (CTRL) matched for sex, age, height, weight current activity level, performed a joint position sense (JPS) test during simultaneous...
