This systematic review and meta-analysis evaluated the effects of low-load exercise with blood flow restriction (LLE-BFR) versus low-load exercise (LLE) and high-load exercise (HLE) in individuals with musculoskeletal conditions. The analysis included 45 RCTs with 1652 participants. LLE-BFR showed superior improvements in muscle strength (SMD=0.82) and disability (SMD=0.63) compared to LLE, while no significant differences were found between LLE-BFR and HLE for muscle strength.
Key findings
- LLE-BFR improved muscle strength compared to LLE (SMD=0.82).
- LLE-BFR also reduced disability more than LLE (SMD=0.63).
- No clear difference in muscle strength was found between LLE-BFR and HLE (SMD=0.08).
- Pain intensity showed small differences favoring LLE-BFR over LLE (MD=4.45).
Why it matters
Understanding the comparative effectiveness of LLE-BFR versus conventional exercises can guide rehabilitation strategies for musculoskeletal conditions, potentially enhancing patient outcomes in muscle strength and disability management.
