Isokinetic Profile of Ankle Muscles in Chronic Non-Specific Low Back Pain Patients

Official title: The Relationship Between Chronic Non-Specific Low Back Pain and Isokinetic Performance of Ankle Joint Muscles

Run by Cairo University · NCT07636967 · Data updated 2026-11-12

This study tests how ankle muscle performance differs in men with chronic non-specific low back pain compared with typical expectations, using isokinetic testing to explore links between pain, function, and fatigue.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are men aged 20-40 with chronic non-specific low back pain (pain >3 months, VAS ≥3, MODI 21-40%) referred by an orthopedic surgeon and meeting other criteria.

Probably not a fit

Individuals with prior back surgery, spine disorders like herniation or stenosis, or chronic ankle instability may not benefit from this study outcomes.

What this trial studies

This observational study uses the Humac Isokinetic system to measure ankle joint muscle strength, endurance, and timing in 50 male adults with chronic non-specific low back pain. Researchers will correlate isokinetic results with pain levels, disability scores, psychological status, and overall fatigue. The study aims to identify patterns in ankle muscle performance that may relate to postural or functional impairments associated with low back pain. Participants will undergo testing under standardized conditions, with data analyzed for dominant versus non-dominant limb differences and relationships to clinical measures. The study is conducted at Al-Salam University with Cairo University as lead sponsor.

Why it matters

Potential benefit: If successful, findings could improve understanding of how ankle muscle function relates to chronic low back pain and potentially inform rehabilitation strategies.

How similar studies have gone: Previous research has explored links between back pain and lower limb function, but data on detailed isokinetic ankle profiles in CNSLBP are limited, making this approach relatively novel.
