OBJECTIVE Chronic pain from rheumatic and musculoskeletal conditions is associated with cortical changes and altered tactile acuity. Tactile acuity is considered a clinical signature of primary somatosensory representation. The two-point discrimination (TPD) threshold is increasingly used both clinically and in research. Remarkably, the reliability and precision of the measure at commonly used sites has not been determined. This study aimed to determine the utility, intra- and inter-rater…

Background Reduced tactile acuity has been observed in several chronic pain conditions and has been proposed as a clinical indicator of somatosensory impairments related to the condition. As some

Reliability of the 2-PD test was considered good-moderate, suggesting that tactile acuity in the trigeminal region is impaired in patients with temporomandibular disorders.

Intra- and Inter-Rater Reliability of Three Measurements for Assessing Tactile Acuity in Individuals with Chronic Low Back Pain

TPD, PTP, and TPE have moderate-to-good intra- and inter-rater reliability on the painful and pain-free sides of the fifth lumbar vertebrae in participants with chronic low back pain at different ages.

Intra‐ and Interobserver Reliability of Sensibility Testing in Asymptomatic Individuals

The data indicate that Semmes‐Weinstein monofilaments and two‐point discrimination tests yield unreliable measurements in asymptomatic individuals.

Quantitative Measure of Cutaneous Sensation

Assessment of two-point discrimination is useful in the clinical evaluation of certain types of patients, but the existence of intraindividual and interindividual differences suggests that therapists must interpret the results of these tests with caution.

Tactile acuity is disrupted in osteoarthritis but is unrelated to disruptions in motor imagery performance.

That TPD and MIP were unrelated in knee OA, but related in back pain, suggests that the relationship between them may vary between chronic pain conditions and suggests against the idea that disrupted cortical representations contribute to the pain of either condition.

Tactile acuity and lumbopelvic motor control in patients with back pain and healthy controls

Tactile acuity, a clear clinical signature of primary sensory cortex organisation, relates to voluntary lumbopelvic control, which raises the possibility that the former contributes to the latter, in which case training tactile acuity may aid recovery and assist in achieving normal motor performance after back injury.

Establishment of reliability in the evaluation of hand sensibility.

Based on the results of this study, evaluation of hand sensibility may be attained with measurement of vibration and cutaneous pressure threshold, two-point discrimination, and object identification.
