This study examined proprioceptive acuity and its relationship with motor function in Mandarin-speaking children with and without developmental language disorder (DLD). Fifteen children aged 9-12 years with DLD and 15 age- and sex-matched typically developing (TD) children participated in this study. Children's motor function was assessed using the second edition of the Movement Assessment Battery for Children (MABC-2). Their proprioceptive acuity was measured based on the absolute error (i.e., proprioceptive bias) and variable error (i.e., proprioceptive precision) when performing joint position matching tasks. Compared with the TD group, the DLD group exhibited impaired motor function and poorer proprioceptive acuity, as evidenced by the lower scores on the MABC-2 and the higher rates of absolute and variable errors in the joint position matching tasks. A significant association between the proprioceptive bias (absolute error) and the MABC-2 total score was also observed in the combined cohort of children with and without DLD. We conclude that DLD is associated with proprioceptive dysfunction.

We investigated proprioceptive acuity for location and motion of a never seen hand-held tool (30 cm long rod) and the accuracy of movements to place tool parts in the location of remembered visual targets. Ten blindfolded right-handed subjects (5 females) reached with the tool held in the right hand to touch the tip and midpoint to the stationary and moving left index-tip, to the right and left ear lobes and to remembered visual target locations. We also tested accuracy of left hand rod reaches to the ear lobes to determine if rod dimensions and control of tool movements experienced during right hand tool use could be used to accurately localize the rod parts when held in the left hand.

Active movement extent discrimination assessment (AMEDA) is a psychophysical task that evaluates proprioception and tactile acuity of the lower limbs, and it is a method of determining sensorimotor ability. Sensorimotor ability is the ability to judge small differences in movement tasks through the process of receiving sensory messages (sensory input) and producing a response (motor output). Participant attention lapses in prior psychophysical studies have been implicated as a cause for increased measurement variance thresholds in these types of assessments.

Introduction: Although the importance of trunk position sense as a clinical outcome measure related to spinal alignment has been established, there is no study evaluating the reliability of measurement techniques for trunk position sense in older adults. Hyperkyphosis is most prevalent in this population and is associated with adverse consequences.
Objective: This study aimed to investigate the test-retest reliability of a measurement technique consisting of photogrammetry and angle calculation in older adults with and without hyperkyphosis.

Background: Neck muscle vibration decreases pain and improves sensorimotor impairments in patients with chronic neck pain. However, the impact of placebo on these effects are still unclear.
Objective: The aim was to evaluate the effect of neck muscle vibration compared to placebo neck muscle vibration in patients with chronic neck pain.

Background: Proprioception is an essential sensory function of the body. Proprioception is defined as one's awareness of their body's position and movement through space. It contributes to both the conscious and unconscious awareness of limb and trunk position and movement.
