The prognosis of self-reported paresthesia and weakness in disc-related sciatica

To explore how patients with sciatica rate the ‘bothersomeness’ of paresthesia (tingling and numbness) and weakness as compared with leg pain during 2 years of follow-up.
Observational cohort study including 380 patients with sciatica and lumbar disc herniation referred to secondary care. Using the Sciatica Bothersomeness Index paresthesia, weakness and leg pain were rated on a scale from 0 to 6. A symptom score of 4–6 was defined as bothersome.
Along with leg pain, the bothersomeness of paresthesia and weakness both improved during follow-up. Those who received surgery (n = 121) reported larger improvements in both symptoms than did those who were treated without surgery. At 2 years, 18.2 % of the patients reported bothersome paresthesia, 16.6 % reported bothersome leg pain, and 11.5 % reported bothersome weakness. Among patients with no or little leg pain, 6.7 % reported bothersome paresthesia and 5.1 % bothersome weakness.
During 2 years of follow-up, patients considered paresthesia more bothersome than weakness. At 2 years, the percentage of patients who reported bothersome paresthesia was similar to the percentage who reported bothersome leg pain. Based on patients’ self-report, paresthesia and weakness are relevant aspects of disc-related sciatica.
