Novel Blood Flow Restriction Therapy Protocol for the Treatment of Postamputation Weakness and Pain due to Osteosarcoma: A Case Study

Abstract

BACKGROUND: Pain and weakness are 2 commonly reported postamputation symptoms. The purpose of this case report is to propose a novel blood flow restriction (BFR) protocol to address pain and weakness in a patient with transtibial limb loss. CASE PRESENTATION: A 36-year-old male 2 months after transtibial amputation presented for evaluation and treatment of his postamputation pain, weakness, and poor functional mobility. The patient completed a novel BFR strength protocol twice per week for 12 weeks. OUTCOME AND FOLLOW-UP: Amputee Mobility Predictor, L Test Measure of Functional Mobility, 2-minute walk test, 30-second sit to stand, hamstring force, single-limb leg press repetition maximum, hip abduction endurance test, and numeric pain scale preintervention and postintervention were measured. The patient achieved the minimal detectable change for the L-Test and 2MWT, resulting in meaningful improvement in the patient’s strength and function following the blood flow restriction protocol. DISCUSSION: This case supports the use of blood flow restriction to address postamputation weakness and pain in a physical therapy setting. JOSPT Cases 2024;4(1):1-7.
