“…These results seem to indicate a more pronounced role of tactile information during localized hand performance (fine movements) in comparison to more global arm movements, which incorporate more muscles and joints. In some previous studies, tactile feedback improved movement accuracy and control during tactile precision-grip tasks [21]. These results seems to highlight the special importance of tactile receptors in the on-line control of fine movement.…”

Purpose. This study aimed at measuring the reaction of the hand when tactile feedback was impaired in upper extremity motor performance in order to empirically evaluate how precision was affected during visually controlled hand and arm movement. Methods. 26 right-handed young male adults were tested with the use of a line tracking task by means of schuhfried's Vienna Test system. Tactile feedback during line tracking task was impaired by the use of different gloves: a chirurgical latex glove, a rubber glove and a thick work glove made of soft animal leather. Results. The results found a strong relationship between hand movement accuracy and the degree of tactile impairment; no significant relationship was found between tactile impairment and movement speed. Limiting tactile feedback was found to influence motor task accuracy during local wrist movements (using only the carpal and palm joints), while tasks that allowed global movement (both wrist and forearm) were found to have accuracy influenced only when tactile feedback was highly impaired (line tracking with the thick leather glove). Conclusions. The results have indicated that the role of tactile feedback on accuracy during visually-guided precision movement is far greater than previously reported.

“…Vice versa, there is recent evidence that concurrent tactile feedback enhances proprioceptive function in another basal-ganglia related disease. In a study with Parkinson's disease patients tactile feedback improved the proprioceptive accuracy in an arm-matching task (Rabin et al, 2010). There is also evidence that stimulating the proprioceptors of the dystonic musculature may overcome dystonic postures.…”

Musician's dystonia (MD) is a neurological motor disorder characterized by involuntary contractions of those muscles involved in the play of a musical instrument. It is task-specific and initially only impairs the voluntary control of highly practiced musical motor skills. MD can lead to a severe decrement in a musician's ability to perform. While the etiology and the neurological pathomechanism of the disease remain unknown, it is known that MD like others forms of focal dystonia is associated with somatosensory deficits, specifically a decreased precision of tactile and proprioceptive perception. The sensory component of the disease becomes also evident by the patients' use of “sensory tricks” such as touching dystonic muscles to alleviate motor symptoms. The central premise of this paper is that the motor symptoms of MD have a somatosensory origin and are not fully explained as a problem of motor execution. We outline how altered proprioceptive feedback ultimately leads to a loss of voluntary motor control and propose two scenarios that explain why sensory tricks are effective. They are effective, because the sensorimotor system either recruits neural resources normally involved in tactile-proprioceptive (sensory) integration, or utilizes a fully functioning motor efference copy mechanism to align experienced with expected sensory feedback. We argue that an enhanced understanding of how a primary sensory deficit interacts with mechanisms of sensorimotor integration in MD provides helpful insights for the design of more effective behavioral therapies.

“…Proprioception is critical in “light-touch” balance control to distinguish fingertip skin deformation as due to either postural drift or arm adjustments [12] . Proprioceptive movement control is impaired by PD [9,13–15] . In particular, proprioceptive balance control [27] , and small amplitude movements such as maintaining constant arm positions [28] are degraded in PD.…”

Parkinson’s disease (PD) degrades balance control. Haptic (touch and proprioception) feedback from light contact with a stationary surface inadequate to mechanically stabilize balance improves balance control in healthy people. In this study we tested whether PD impairs use of haptic cues independent of mechanical support to control balance. We measured postural sway in thirteen individuals with PD (H&Y 1–3, median=2, Q1=2, Q3=2) and thirteen age-matched controls balancing in a widened, sharpened Romberg stance in four conditions: eyes-closed, no manual contact; eyes-closed light-touch contact (<1N), eyes-closed, unrestricted contact; and eyes-open, no contact. To determine whether PD-severity affects any of these balance strategies, PD participants were tested on- and off-medication, and using the more- and less-affected body side in the stance and manual contact. Individuals with PD simultaneously maintained non-supportive fingertip contact and balance in this task without practice. PD participants swayed more than control participants (ML CP p=0.010; shoulder p<0.001), but manual contact reduced sway. Non-supportive manual contact stabilized balance more than vision (p<0.05). PD-severity factors had no significant effect (p>0.05). We conclude the effect of PD on balance is not specific to vision or haptic feedback. Nevertheless, haptic cues from manual contact, independent of mechanical support, improve balance control in individuals with PD. We discuss the implication that PD or associated dopaminergic pathways do not directly affect haptic feedback balance control mechanisms, including arm/posture coordination and proprioceptive integration.
