Objective: During the transitional phase (ambulatory to non-ambulatory), synergies characterize the evolution of Duchenne muscular dystrophy (DMD). This study was performed to describe and quantify compensatory movements while sitting down on/rising from the floor and climbing up/down steps.
Method: Eighty videos (5 children × 4 assessments × 4 tasks) were recorded quarterly in the year prior to gait loss. Compensatory movements from the videos were registered based on the Functional Evaluation Scale for DMD.
Results: The most frequently observed compensatory movements were upper limb support on lower limbs/floor/handrail during all the tasks and lumbar hyperlordosis, trunk support on handrail, equinus foot, increased base of support, non-alternated descent, and pauses while climbing up/down steps.
Conclusion: Climbing up/down steps showed a higher number of compensatory movements than sitting down on/rising from the floor, which seemed to be lost before climbing up/down steps in ambulatory children with DMD.

Vertebrates stabilize gaze using a neural circuit that transforms sensed instability into compensatory counterrotation of the eyes. Sensory feedback tunes this vestibulo-ocular reflex throughout life. We studied the functional development of vestibulo-ocular reflex circuit components in the larval zebrafish, with and without sensation.

Age-dependent sensory impairment, memory loss, and cognitive decline are generally attributed to neuron loss, synaptic dysfunction, and decreased neuronal activities over time. Concurrently, increased neuronal activity is reported in humans and other organisms during aging. However, it is unclear whether neuronal hyperactivity is the cause of cognitive impairment or a compensatory mechanism of circuit dysfunction.

Long-latency reflexes (LLRs) are critical precursors to intricate postural coordination of muscular adaptations that sustain equilibrium following abrupt disturbances. Both disturbances and adaptive responses reflect excursions of postural control from quiescent Gaussian stability under a narrow bell curve, excursions beyond Gaussianity unfolding at many timescales. LLRs slow with age, accentuating the risk of falls and undermining dexterity, particularly in settings with concurrent additional tasks.

Physical activity (PA) and fruit and vegetable consumption (FVC) are crucial factors jointly affecting young adults' physical and mental health. However, the psychosocial interactive mechanisms of these behaviors remain understudied. Using a two-wave prospective design over two months, this study investigated the psychological mechanisms underlying multiple health behavior change (MHBC) through a novel two-layer social-cognitive framework, the Compensatory Carry-Over Action Model (CCAM), among 322 Chinese college students (19.

Unlabelled: Purpose: Chemotherapy-induced peripheral neuropathy (CIPN) with associated weakness, areflexia, neuropathic pain, and sensory loss, is a common occurrence in children treated for cancer. However, accurate, quantifiable descriptions of gait deviations due to CIPN are lacking. This scoping review explores common gait abnormalities in children with CIPN.
