Key result
Blood flow restriction training combined with low-load resistance exercises may reduce pain and improve functional outcomes following upper extremity injuries, though current evidence is limited.
Why the study?
Further studies focusing on blood flow restriction training after upper extremity injuries are needed to establish its potential clinical impact.
Does blood flow restriction training improve muscle strength, hypertrophy, and clinical outcomes in patients with upper extremity injuries?
Does blood flow restriction training improve muscle strength, hypertrophy, and clinical outcomes in patients with upper extremity injuries?
Blood flow restriction training combined with low-load resistance training shows potential for improving rehabilitation outcomes in upper extremity injuries, but requires further large-scale studies.
Hypothesis-generating for BFR in upper extremity rehab; larger RCTs needed before clinical adoption.
Blood flow restriction (BFR) utilizes a cuff or tourniquet to induce muscle hypoxia by maintaining arterial flow, while restricting venous return. This technique has recently gained popularity in healthy patients and patients undergoing rehabilitation. Two studies have shown that patients who use BFR, in addition to the standard therapy protocol, following an upper extremity injury (UEI) have reduced pain and improved Patient-Reported Wrist Evaluation scores. The use of BFR in the upper extremity of healthy patients and patients with a prior lower extremity injury have shown statistically significant improvements in muscle strength and muscle hypertrophy. Further studies focusing on BFR training following various upper extremity injuries are needed to determine the potential impact on clinical outcomes. The purpose of this review was to analyze the use of BFR following lower extremity injuries, summarize the literature of BFR for upper extremity injuries, and consider the application of BFR following upper extremity injuries in the future.

Stevens et al. (2022) conducted a review in Upper Extremity Injuries. Blood Flow Restriction (BFR) training vs. Standard rehabilitation without BFR was evaluated. Blood flow restriction training combined with low-load resistance exercises may reduce pain and improve functional outcomes following upper extremity injuries, though current evidence is limited.
