  "description": "Sequential movements to mobilize the median nerve: shoulder ABD → elbow extension → wrist/finger extension → cervical lateral flexion. Neurodynamic mobilization: 100% subjective improvement vs 0% controls (RR 15.00). Significantly reduces CTS symptom severity (MD -1.20) and functional severity (MD -1.06). Most effective combined with splinting.",
