Objective: correlate between clinical and electrophysiological findings of carpal tunnel syndrome Methods: cross sectional study at outpatient setting.109 patients (83females, 26males) with clinical manifestations of carpal tunnel syndrome participated in the study.All the patients had the following: Medical history and neurological examination including Tinel's sign and Phalen test and nerve conduction studies including medianulnar, median -radial comparative studies and electromyography of both upper extremities.Results: mean age 57.71±13.4. pain was mild in 9.2%, moderate in 25.7% and severe in 56% of patients. Numbness was present in 87.2%. Impaired sensory exam in 43.1% Impaired motor exam in 8.3%. Positive Tinel's sign unilateral (38.5%) and bilateral (47.7%). Positive Phalen test unilateral (30.3%) and bilateral (34.9%). Unilateral thenar Muscle wasting in 4.6% and bilateral in 1.8%. Pure sensory median neuropathy was found in 65 patients (59.6%), sensory motor median neuropathy in 44 patients (40.37%). Demyelinating neuropathy in 91.7% and demyelinating-axonal neuropathy in 8.3% of patients.Abnormal distal motor latency was significantly correlated with severity of pain p=0.0025, impaired sensory exam p=0.0001, impaired motor exam p=0.0001, positive Tinel's sign of both hands p=0.0001, positive Phalen test of both hands p=0.0001. as well as with unilateral or bilateral muscle wasting p=0.001.Prolonged peak median sensory latency was significantly correlated with numbness p=0.0001, severity of pain p=0.001, Impaired sensory exam p=0.005, positive Tinel's sign for either one or both hands p=0.0001, positive Phalen test of one or both hands p=0.0001Conclusion: Highly significant correlation was found between subjective and objective sensory manifestation and peak median sensory latency. While distal motor latency were significantly correlated with severe pain, only bilateral positive Tinel's sign and Bilateral Phalen test and the objective sensory and motor deficit.
