Prevalence and Demographic Distribution of Hypermobility in a Random Group of School-Aged Children in Nigeria KU Leuven
BACKGROUND: The purpose of this study was to determine the prevalence of hypermobility in randomly selected healthy children, without previous trauma or disease process affecting the joints and whether other demographic variables (age, sex, BMI) had an impact on Beighton scores and range of motion (RoM) in children between 6 and 10 years of age. RESULTS: 286 children were included; 27.3% of them had a Beighton score ≥7/9 and 72% would be ...
Multifactorial Assessment of Older Adults Able and Unable to Recover Balance During a Laboratory-induced Trip. KU Leuven
BACKGROUND: Older adults are prone to falls, and identifying fallers and non-fallers from a set of fall-related variables is essential while establishing effective preventive programs. AIMS: This study aimed to analyze if a set of parameters (i.e., strength, functional status, dynamic balance, gait, and obesity-related anthropometric measures) differ between older adults able and unable to recover from an induced trip. OBJECTIVE: To analyze ...
Sleep deprivation affects gait control KU Leuven
Different levels of sleep restriction affect human performance in multiple aspects. However, it is unclear how sleep deprivation affects gait control. We applied a paced gait paradigm that included subliminal rhythm changes to analyze the effects of different sleep restriction levels (acute, chronic and control) on performance. Acute sleep deprivation (one night) group exhibited impaired performance in the sensorimotor synchronization gait ...
Treatment of metatarsalgia based on claw toe deformity through soft tissue release of the metatarsophalangeal joint and resection of the proximal interphalangeal joint: Evaluation based on foot kinematics and plantar pressure distribution KU Leuven
INTRODUCTION: This study investigated the effect of operative claw toe correction with release of the metatarsophalangeal (MTP) joint, repositioning of the plantar fat pad and resection of the proximal interphalangeal joint on foot kinematics, plantar pressure distribution and Foot Function Index (FFI). METHODS: Prospective experimental study with pretest-posttest design. The plantar pressure, 3D foot kinematics and the FFI of 15 patients with ...
Effects of ageing on responses to stepping-target displacements during walking KU Leuven
PURPOSE: Human sensory and motor systems deteriorate with age. When walking, older adults may therefore find it more difficult to adjust their steps to new visual information, especially considering that such adjustments require control of balance as well as of foot trajectory. Our study investigates the effects of ageing on lower limb responses to unpredictable target shifts. METHODS: Participants walked on a treadmill with projected stepping ...
Fast responses to stepping-target displacements when walking KU Leuven
KEY POINTS: Goal-directed arm movements can be adjusted at short latency to target shifts. We tested whether similar adjustments are present during walking on a treadmill with shifting stepping targets. Participants responded at short latency with an adequate gain to small shifts of the stepping targets. Movements of the feet during walking are controlled in a similar way to goal-directed arm movements if balance is not violated. ABSTRACT: It is ...
Judging heel height: A new test for proprioception while standing reveals that young hypermobile children perform better than controls KU Leuven
BACKGROUND: Children with Generalized Joint Hypermobility (GJH) have been reported to have poorer proprioception than children with normal mobility. However, they were usually tested under unloaded conditions and in an age-group in which pain starts to play a role. RESEARCH QUESTION: In contrast, some young children with GJH perform well in motor tasks, suggesting they may have good proprioceptive abilities if assessed more ecologically. ...
Is the manual following response an attempt to compensate for inferred self-motion? KU Leuven
If the surrounding of a visual target unexpectedly starts to move during a fast goal-directed hand movement, the hand reflexively moves along with it. This is known as the 'manual following response'. One explanation for this response is that it is a compensation for inferred self-motion in space. Previous studies have shown that background motion gives rise to both postural responses and deviations in goal-directed hand movements. To evaluate ...
