Figure 2 Longitudinal assessment of lumbar erector spinae muscle symmetry following ultrasound-guided platelet-rich plasma therapy. A: Pretreatment measurement demonstrating significant asymmetry (left: 2.3 cm; right: 3.6 cm; difference: 1.3 cm); B: 3-month post-treatment reduction in asymmetry (left: 3.5 cm; right: 3.8 cm; difference: 0.3 cm); C: 6-month follow-up showing near-symmetrical restoration (left: 4.4 cm; right: 4.6 cm; difference: 0.2 cm). White arrow: Affected side (left erector spinae). Black arrow: Unaffected side (right erector spinae). Dashed line: Muscle width measurement boundaries. Circle: Palpated spinous process landmark. L: Left side.
