Is tactile acuity altered in individuals with acute mechanical neck pain?
It can be concluded that individuals with acute mechanical neck pain demonstrated a change in tactile acuity, which may suggest the extent of the altered threshold of sensory discriminative aspect of pain experience.
Pain sensitivity and tactile spatial acuity are altered in healthy musicians as in chronic pain patients
The significant increment of pain sensitivity together with decreased spatial discrimination in pain-free musicians and the similarity of results found in chronic pain patients, suggests that the extensive training of repetitive and highly skilled movements in classical musicians could be considered as a risk factor for developing chronic pain.
Is tactile acuity altered in people with chronic pain? a systematic review and meta-analysis.
Correlations between Age, Pain Intensity, Disability, and Tactile Acuity in Patients with Chronic Low Back Pain
It is indicated that tactile acuity was negatively associated with age, pain intensity, and disability in young patients with chronic low back pain.
Tactile acuity is reduced in people with chronic neck pain.
Selectivity of conditioned fear of touch is modulated by somatosensory precision.
Specificity of fear responses appears to be affected by somatosensory precision, which has implications for the understanding of the role of sensory imprecision in the development of chronic pain.
Tactile acuity training for patients with chronic low back pain: a pilot randomised controlled trial
This pilot RCT found tactile acuity training to be no more effective than sham tactile acity training for function and less effective for pain in individuals with CLBP.
Motor Imagery Performance and Tactile Spatial Acuity: Are They Altered in People with Frozen Shoulder?
If motor imagery performance assessed by the left/right judgement task, and tactile acuity assessed by two-point discrimination, are altered in people with unilateral frozen shoulder, a case exists for the use of treatments aimed at reversing these changes, training the brain to reduce chronic shoulder pain.


Mislocalization of tactile stimulation in patients with complex regional pain syndrome
The occurrence of mislocalizations was correlated with a detailed psychophysical examination in which sensory, motor and autonomic symptoms were assessed and support the concept of pain–induced reorganization in the somatosensory system of CRPS patients.
Simulating sensory-motor incongruence in healthy volunteers: implications for a cortical model of pain.
The hypothesis that motor-sensory conflict can induce pain and sensory disturbances in some normal individuals is supported and it is proposed that prolonged sensory-motor conflict may induce long-term symptoms in some vulnerable subjects.
Extensive reorganization of primary somatosensory cortex in chronic back pain patients
Sensorimotor returning in complex regional pain syndrome parallels pain reduction
Patients with complex regional pain syndrome (CRPS) and intractable pain showed a shrinkage of cortical maps on primary and secondary somatosensory cortex contralateral to the affected limb, which suggests that the reversal of tactile impairment and cortical reorganization in CRPS is associated with a decrease in pain.
Mean sustained pain levels are linked to hemispherical side-to-side differences of primary somatosensory cortex in the complex regional pain syndrome I
Low pain levels were linked to small representational side-to-side differences, while subjects with a distinctive hemispherical asymmetry reported the highest pain levels, and follow-up studies using functional imaging methods might be instrumental in providing a better understanding.
Graded motor imagery for pathologic pain
Motor imagery reduced pain and disability in these patients with complex regional pain syndrome type I or phantom limb pain, but the mechanism, or mechanisms, of the effect are not clear.
Phantom-limb pain as a perceptual correlate of cortical reorganization following arm amputation
A very strong direct relationship is reported between the amount of cortical reorganization and the magnitude of phantom limb pain (but not non-painful phantom phenomena) experienced after arm amputation, indicating that phantom-limb pain is related to, and may be a consequence of, plastic changes in primary somatosensory cortex.
Improvement and Decline in Tactile Discrimination Behavior after Cortical Plasticity Induced by Passive Tactile Coactivation
It was found that a few hours of Hebbian coactivation evoked a significant increase of primary and secondary somatosensory cortical areas representing the stimulated body parts, and the amount of plastic changes was strongly correlated with improvement in spatial discrimination performance.
