Clinical examination was done for all patients. The standardized semi-quantitative clinical History-Objective (Hi-Ob) scale was used to assess the CTS severity by integrating symptoms with clinical features. The Hi-Ob scale has 5 stages of severity. Stage 1: it represents the mildest form of CTS with the presence of nocturnal paresthesia only. Stage 2: the paresthesia occurs at day time with no objective sensory deficits. Stage 3: there is sensory deficit in the presence of nocturnal or diurnal symptoms. Stage 4: the presence of motor weakness with mild atrophy of median innervated thenar muscles. Stage 5: there is complete atrophy or plegia of median innervated thenar muscles [13].
