治疗关节炎的 4 级激光疗法和深层组织激光疗法：推进无创医学

导言

Arthritis is a multifactorial condition leading to progressive joint pain, stiffness, and functional disability. Standard therapies such as NSAIDs, corticosteroids, and surgical interventions provide symptomatic relief but come with side effects and long-term risks. The advent of 4 级激光治疗 和 深层组织激光疗法 represents a paradigm shift in managing arthritis, offering safe, non-invasive, and scientifically validated outcomes.

Biological Mechanisms

Laser therapy acts at the molecular and cellular levels, enabling tissue repair and anti-inflammatory effects. Mechanisms include:

• 光生物调节: Enhances mitochondrial respiration and ATP synthesis.
• Anti-inflammatory modulation: Reduces COX-2 expression and pro-inflammatory cytokines.
• 减轻疼痛: Alters nociceptor sensitivity and increases endogenous opioid release.
• 组织再生: Stimulates fibroblast and chondrocyte activity for cartilage repair.

Clinical Efficacy in Arthritis

Laser therapy for arthritis has been demonstrated to:

• Reduce pain severity and stiffness.
• Improve range of motion and functional ability.
• Complement pharmacological and physiotherapeutic regimens.

Meta-analyses confirm improved VAS pain scores and functional indices (WOMAC, HAQ) compared to sham treatment.
