Introduction: Sensory modulation refers to a condition in which an individual's behavioural responses to sensory stimuli do not correspond to the nature or intensity of the stimuli. Sensory modulation affects children's participation in everyday activities and their well-being. The most common assessments used are caregiver questionnaires. Our aim is twofold; first to develop a clinical evaluative measure, the Sensory Adventure Measure (SAM), for directly assessing sensory modulation in children via therapists and children's self-report, second, we aim to establish its reliability and validity.
Methods: The study sample comprised 87 children ranging in age from 4 to 6 years and 11 months old divided into two groups: study group included 63 children with mild developmental disabilities and the control group included 24 typically developed children. The SAM's internal consistency, test-retest reliability, and inter-rater reliability were examined. In addition, criterion validity was established using the total score of the Short Sensory Profile (SSP) and construct validity was established by known group differences.
Results: The SAM exhibited good internal consistency (α = 0.83, 0.85) and moderate to very good test-retest reliability (r = 0.96, 0.98, 0.75). Inter-rater reliability was strong (r = 0.80-0.83). Moderate correlation was found between the SAM Therapist Rating of Magnitude total score and the total score of the SSP and significant differences were found in the SAM scores between groups thus establishing validity.
Conclusions: The SAM demonstrated good psychometric properties and can be used as a reliable and valid measure to assess sensory modulation among children aged 4 to 6 years. The SAM can be used by therapists to assess sensory modulation disorder based on observed responses to sensory stimuli and the child's self-report. The SAM contributes additional perspective to the evaluation process of sensory modulation disorder.

Spinal cord injury (SCI) is one of the devastating neurological disorders that leads to a loss of motor and sensory functions. Long non-coding RNA small nucleolar RNA host gene 6 (lncRNA SNHG6) plays a crucial role in inflammatory regulation across various diseases. This study investigates the role of SNHG6 in SCI development and its underlying regulatory mechanisms.

It remains unclear however whether or not noise exposure also compromises the cochlear efferent system, a feedback pathway in the brain that fine-tunes hearing sensitivity in the cochlea. We examined the effects of noise-induced hearing loss on the spontaneous action potential (AP) firing pattern in mouse lateral olivocochlear (LOC) neurons.

However, the role sympathetic axons play in the persistent dysfunction that occurs after nerve injuries remains to be explored. Peripheral nerve injuries are common and lead to motor, sensory, and autonomic deficits that result in lifelong disabilities.

Here, we explore a different theory, whereby DD emerges from local network-level interactions within a neocortical column. We propose that deviance-driven neural dynamics can emerge through interactions between ensembles of neurons that have a fundamental inhibitory motif: competitive inhibition between reciprocally connected ensembles under modulation from feed-forward selective (dis)inhibition.

Globally, 537 million people suffer from diabetes mellitus (DM), a condition often associated with sensory disturbances, wound development, and chronic pain, which significantly affects the quality of life and imposes a substantial economic burden. This study evaluated the effects of photobiomodulation (PBM) therapy on nociceptive and sensory changes in diabetic patients to understand pain manifestations and explore PBM's molecular mechanisms on wound healing. Twenty patients with type 2 DM underwent clinical assessments, completed pain and quality of life questionnaires, and had their pain sensitivity evaluated using the quantitative sensory test (QST).
