Introduction:
Two-point discrimination (2PD) is an integral part of every neurovascular examination of the hand. However, sparse studies have compared static versus dynamic 2PD. We developed a standardized and reproducible approach to compare both modalities, aiming to evaluate which is more reliable in detecting nerve recovery following cold-induced paresthesia.
Methods:
An experimental cross-sectional study performed at King Abdulaziz University Hospital was done in two phases. Cold exposure, using ice packs, was utilized to induce paresthesia in both index and little fingertips. Phase one included 33 participants and aimed to identify the timing of onset of paresthesia following cold exposure. Phase 2 included 100 participants and aimed to compare static vs dynamic 2PD in detecting onset of paresthesia and recovery. Fine touch was also tested in both phases.
Results:
The study was performed on healthy individuals between 15-35 years of age. P-values of
Key words: Two-point discrimination; fine touch; sensibility; nerve regeneration.
