Healthy ageing involves degeneration of the neuromuscular system which impacts movement control and proprioception. Yet the relationship between these sensory and motor deficits in upper limb reaching has not been examined in detail. Recently, we reported that age-related proprioceptive deficits were unrelated to accuracy in rapid arm movements, bu...

During normal healthy ageing there is a decline in the ability to control simple movements, characterised by increased reaction times, movement durations and variability. There is also growing evidence of age-related proprioceptive loss which may contribute to these impairments. However, this relationship has not been studied in detail for the uppe...

It is uncertain how vision and proprioception contribute to adaptation of voluntary arm movements. In normal participants, adaptation to imposed forces is possible with or without vision, suggesting that proprioception is sufficient; in participants with proprioceptive loss (PL), adaptation is possible with visual feedback, suggesting that proprioc...

During normal healthy ageing there is a deterioration in motor control which is characterized by increased reaction times, movement durations and kinematic variability. This is thought to be due to a multi-factorial process of general sensorimotor system decline, yet the extent to which proprioceptive sensory loss contributes to age-related motor i...

BACKGROUND - Recently, it has been reported that proprioceptive acuity measured during passive wrist movement in the elderly is not predictive of their active motor performance (Helsen et al. 2016). Here, we used a 2D robotic manipulandum device to investigate whether dynamic proprioceptive acuity could better predict reaching motor performance in...
