The Electric Lumbar Traction Devices ecosystem spans raw‑material sourcing, device assembly, and final delivery with support. Upstream participants supply motors, steel or aluminum frames, electronic boards, and medical‑grade plastics. Midstream actors—original equipment manufacturers and system integrators—combine components, embed software, and certify devices to clinical standards. Downstream, distributors and service firms handle logistics, installation, training, and maintenance, while health‑care facilities, rehabilitation clinics, and home‑care patients are the ultimate buyers. Value is generated through engineering differentiation, regulatory compliance, and service contracts, and captured by manufacturers via product margins, by distributors through channel mark‑ups, and by service firms via recurring support fees.
