About
This study is designed to compare the effectiveness of two physiotherapy techniques-Dry Needling and the Cyriax Technique-in people suffering from chronic low back pain (CLBP) that radiates to the outer thigh, a condition commonly known as meralgia paresthetica.
Meralgia paresthetica occurs when a nerve called the lateral femoral cutaneous nerve (LFCN) gets compressed, leading to pain, numbness, tingling, or burning sensations in the front or side of the thigh. Many patients also experience difficulty in performing daily activities because of these symptoms.
Dry Needling is a modern treatment where fine, sterile needles are inserted into specific muscles to relieve tension and improve nerve function. It is believed to release natural pain-relieving chemicals and reduce inflammation.
On the other hand, the Cyriax Technique is a manual therapy approach involving deep friction massage and gentle mobilizations targeted at the affected nerve area to reduce pressure and pain.
In this study, 80 participants between the ages of 30 and 50 years, who have had low back pain for more than three months and symptoms of nerve entrapment in the thigh, will be randomly divided into two groups. One group will receive Dry Needling therapy, and the other will receive Cyriax treatment. Both groups will also receive standard physiotherapy, including heat therapy, muscle stimulation, and stretching exercises. Treatment will continue for 8 weeks (2 sessions per week).
The aim is to evaluate and compare changes in pain, tingling/numbness (paraesthesia), and daily life functioning using recognized clinical tools such as the Visual Analogue Scale (VAS), Neuropathic Pain Symptom Inventory (NPSI), and the Roland-Morris Disability Questionnaire (RMDQ). Data will be collected at the beginning, and then again after 2, 4, and 8 weeks.
This research will help determine which therapy-Dry Needling or Cyriax-is more effective in treating patients with this type of nerve-related back and thigh pain. The findings may guide physiotherapists and healthcare providers in choosing the most suitable treatment for managing meralgia paresthetica in chronic low back pain.
Full description
Chronic low back pain (CLBP) with radiating symptoms to the anterolateral thigh, often due to meralgia paresthetica (MP), represents a complex clinical presentation with both musculoskeletal and neuropathic components. MP results from entrapment or irritation of the lateral femoral cutaneous nerve (LFCN), leading to symptoms such as numbness, tingling, burning sensations, and pain in the outer thigh. These symptoms can significantly impair quality of life and physical functioning.
This randomized controlled trial aims to compare two physiotherapeutic interventions-Dry Needling (DN) and the Cyriax Technique-with respect to their impact on pain relief, reduction of paraesthesia, and improvement in functional disability among patients with MP secondary to CLBP.
Participants will be screened based on strict inclusion and exclusion criteria. Eligible participants will be adults aged 30-50 years, diagnosed with CLBP lasting more than three months and exhibiting characteristic symptoms of MP. Exclusion criteria include prior spinal surgery, coagulopathies, serious neurological disorders, or contraindications to dry needling.
After obtaining informed consent, participants will be randomly allocated to either the experimental group (DN) or control group (Cyriax) using computer-generated randomization. Both groups will receive 16 treatment sessions over 8 weeks (2 sessions per week), in addition to standard physiotherapy consisting of heat therapy, electrical muscle stimulation, and targeted exercises.
The dry needling group will receive intramuscular stimulation along the anatomical route of the LFCN, targeting muscles including piriformis, psoas major, iliacus, tensor fasciae latae, vastus lateralis, and sartorius. Aseptic technique using solid filiform needles will be followed, with each needle retained in situ for 15 minutes per session.
The Cyriax group will receive deep transverse friction massage along the LFCN pathway, focused around the anterior superior iliac spine (ASIS), with repeated mobilizations aimed at releasing nerve entrapment and relieving local tissue tension.
Blinding will be maintained at the assessor level to reduce bias. Outcomes will be evaluated using standardized tools:
Visual Analogue Scale (VAS) for pain intensity,
Neuropathic Pain Symptom Inventory (NPSI) for paraesthesia,
Roland-Morris Disability Questionnaire (RMDQ) for functional disability.
These assessments will be conducted at baseline, 2nd, 4th, and 8th weeks of the intervention period. The study is powered at 80% with a 95% confidence interval to detect statistically significant between-group differences. Statistical analysis will be performed using SPSS, with ANOVA applied for both intra- and inter-group comparisons.
This trial is expected to provide clinically meaningful insights into which physiotherapy technique yields better therapeutic outcomes in MP associated with chronic low back pain. It will also contribute to evidence-based practice by addressing a gap in the comparative literature for these two commonly used interventions in musculoskeletal and peripheral nerve-related pain management.
