Bowen technique with retro-walking to loosen hamstrings in people with knee osteoarthritis

Effects of Bowen Technique With Retro-walking on Hamstring Flexibility in Knee Osteoarthritis Patients

Not applicable Interventional Riphah International University · NCT07238751

This will test whether Bowen technique combined with retro-walking improves hamstring flexibility, reduces pain, and boosts mobility in adults with mild-to-moderate knee osteoarthritis.

What this trial studies

This randomized controlled trial compares a combined Bowen manual-therapy program plus retro-walking to conventional physiotherapy in adults with knee osteoarthritis and bilateral hamstring tightness. Eligible participants are aged 40–60 with Kellgren-Lawrence grade I–II disease, pain for more than three months, VAS >3, and objective hamstring tightness. Outcomes include hamstring flexibility, pain, dynamic mobility, and knee-related disability measured over the treatment period at Shaafi International Hospital in Islamabad. Key exclusions are meniscal or ligamentous injuries, recent intra-articular steroid injection, major comorbidity, pregnancy, recent surgery, or prior regular flexibility programs.

Who should consider this trial

Good fit: Ideal candidates are adults 40–60 years old with mild-to-moderate (Kellgren-Lawrence I–II) bilateral knee OA who have hamstring tightness, VAS pain >3, and symptoms longer than three months without major comorbidities.

Not a fit: People with advanced OA (Kellgren-Lawrence III–IV), meniscal or ligament injuries, recent steroid injections, significant comorbidity, pregnancy, recent surgery, or current participation in other flexibility programs are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the combined Bowen and retro-walking approach could non-surgically improve hamstring flexibility, reduce pain, and enhance walking mobility and daily function for people with mild-to-moderate knee OA.

How similar studies have performed: Some small physiotherapy and manual-therapy studies report improvements in flexibility and pain with retro-walking and related manual techniques, but high-quality randomized evidence specifically for Bowen technique combined with retro-walking in knee OA is limited.
