Two-point discrimination is widely used to measure tactile spatial acuity. The validity of the two-point threshold as a spatial acuity measure rests on the assumption that two points can be distinguished from one only when the two points are sufficiently separated to evoke spatially distinguishable foci of neural activity. However, some previous research has challenged this view, suggesting ins...

Background: Two-point discrimination test (2PD) represents large sensor fiber, which is more sensitive than smaller fiber to detect abnormality in carpal tunnel syndrome (CTS). Few studies have focused 2PD diagnose CTS.
 Objective: The study aimed establish the cutoff value of determine Methods: A descriptive diagnostic was conducted at Outpatient Department Rehabilitation Medicine, Phramo...

Two Point Discrimination test is notorious for their unexplained variations within subjects, between subjects, and between studies. This paper presents a systematic study of these variations and proposes a simple design to control the variations, thereby improving the TPD measurement accuracies. In the proposed Isobaric Aesthesiometer, monofilaments are used replacing the rigid prongs in a hand...

Two-point discrimination is the distinction of two points put to skin at same time (TPD). Objective: The main objective this study determine variation in two-point sense with increasing age among diabetic population. Methods: Cross Sectional conducted 309 Diabetic Participants from 21-60 years. Data Collected University South Asia, Lahore. Study completed within 6 months (from 5th September 201...

Non-somatic causes of pain may aggravate painful complaints and complicate the conservative management of diseases such as lumbo-sacral disk root disease. The two-point discrimination test has been used for assessment of diseases, which change patients' skin sensation. This study aims to find out how applicable is two-point discrimination test in the conservative treatment of lumbo-sacral disk ...

The two-point discrimination threshold (2PDT) has been used to investigate the integration of sensory information, especially in relation spatial acuity. 2PDT investigated for both innocuous mechanical stimuli and noxious thermal stimuli; however, previous studies different stimulation modalities compare stimuli. This study 19 healthy participants, using (laser) modalities. Within each modality...
