Two-point discrimination values vary depending on test site, sex and test modality in the orofacial region: a preliminary study
TLDR
The normal values of TPD in this study suggest that the cheek and forehead were less sensitive than other regions evaluated and women were more sensitive than men.
Comparison of reliability and efficiency of two modified two-point discrimination tests and two-point estimation tactile acuity test
TLDR
The modified TPD testing methods demonstrated similar reliability to previous research, even with reduced runs allowing for increased efficiency in performing the test, while the TPE method showed poor reliability.
Reliability of two-point discrimination test in carpal tunnel syndrome patients
TLDR
The execution of two repeated measurements provides adequate reliability in measurements of 2PD test in CTS patients and is recommended for clinical trials, which reduces the smallest detectable difference (SDD) value < 1 mm in all cases.
Inter-rater reliability of two-point discrimination in acute stroke patients.
TLDR
The ability for 2 PD sensation was significantly reduced in all examined fingers on the affected side in comparison to the non-affected side and the 2PD sensation values for all fingers were higher for the affected site in compared to theNon-affected site.
The normal sensibility of the hand declines with age – a proclamation for the use of delta two‐point discrimination values for sensibility assessment after nerve reconstruction
TLDR
To overcome shortcomings of classification systems that do not consider the patient's age and inter‐individual differences, the difference of the static 2PD values of the injured to the uninjured contralateral nerve (delta 2PD) is suggested for assessment of sensibility after digital nerve reconstruction.
The Effect of Applied Force on Two-Point Discrimination Threshold in the Trigeminal Region.
TLDR
It is suggested that increased intensity of mechanical stimuli could increase tactile acuity as measured by the TPD test, and both gender groups showed a significant decrease in TPD thresholds.
The reliability and validity of the locognosia test after injuries to peripheral nerves in the hand.
TLDR
The locognosia test has excellent test-retest reliability, is a valid test of tactile spatial discrimination and should be included in the evaluation of outcome after injury to peripheral nerves.
Assessment of two point discrimination threshold on the thumbs of healthy adult Nigerians
TLDR
The mean twopoint discrimination value obtained in this study, for the subjects aged 18 to 25 years is comparable to the normative value reported for a similar age group in other regions.
Analysis of the two-point discrimination test in daily routine practice
TLDR
The results showed that the 2PD test is a valuable examination to diagnose nerve injuries of fingers in hand trauma patients and is a simple, reliable, and available examination tool and therefore can be suggested in daily clinical practice.

Comparing the Responsiveness over Time of Two Tactile Gnosis Tests: Two-Point Discrimination and the STI-Test
TLDR
It is concluded that the STI test is sensitive to change and should be used as an alternative to or at least complement the 2PD test when evaluating tactile gnosis after nerve repair.

TLDR
It remains too difficult for patients to obtain a measurable threshold value on 2PD and the test therefore lacks responsiveness and the rating of outcome from peripheral nerve repair should not be based solely on 2 PD testing and must include other tests of tactile sensibility.
Two-point discrimination test of the skin as an index of sensory aging.
TLDR
The two-point discrimination test of the skin can be used as a powerful and simple index of sensory aging, independent of those of visual accommodation tests and hearing loss of high-frequency sound.

Validation of Cutaneous Pressure Threshold Measurements for the Evaluation of Hand Function
TLDR
Cutaneous pressure threshold measurements with this device had a statistically significant correlation with the small-object subset of the Mayo Dexterity Test and with the object recognition test, demonstrating that the Pressure-specifying Sensory Device is a valid tool for evaluating the sensory aspect of hand function.
