Background Tactile acuity is defined as the skin’s ability to discriminate spatial patterns of stimulation. The two-point discrimination (TPD) threshold is commonly used to assess tactile acuity in non-specific low back pain (nsLBP) [1]. Another approach, the two-point estimation (TPE) task [2], is more time-efficient and, therefore potentially suitable for clinical use. The TPD is closely linked to functional and structural reorganisation in the primary somatosensory cortices (S1) [3] [4], yet studies on neural correlates of TPE are lacking. This study aims to identify potential associations between outcomes of…
