Meralgia Paresthetica Clinical Trial
Official title:
Conservative Treatment Versus Ultrasound Guided Injection in Management of Meralgia Paresthetica: A Randomized Controlled Trial
Meralgia paresthetica (MP) is an entrapment mononeuropathy of the lateral femoral cutaneous
nerve (LFCN), where conservative treatment options are not always sufficient.
The aim of this study was to evaluate the efficacy of ultrasound (US) guided lateral femoral
cutaneous nerve injection in the management of meralgia paresthetica by comparing with
transcutaneous electrical nerve stimulation (TENS) therapy and sham transcutaneous electrical
nerve stimulation therapy.
In this prospective, randomized, sham-controlled study, fifty four patients (23 female and 31
male, the mean age 53.61±11.99 years) with lateral femoral cutaneous nerve compression with
clinical and electrophysiological findings were enrolled. Patients were randomly assigned to
three groups: 1) Ultrasound-guided injection group, 2) TENS group, 3) Sham TENS group. The
blockage of the lateral femoral cutaneous nerve was performed for therapeutic meralgia
paresthetica management in group 1. Ten sessions of conventional TENS were administered to
each patient 5 days a week for 2 weeks, for 20 minutes per daily session in Group 2, and sham
TENS was applied to group 3 with the same protocol.
Visual Analog Scale (VAS), painDETECT questionnaire (PD-Q), Semmes Weinstein monofilament
test (SWMt), Pittsburgh Sleep Quality Index (PSQI) and health-related quality of life (SF
36), at onset (T1), 15 days after treatment (T2) and 1 month after treatment (T3) were used
for evaluation.
