Summary: The study compared the use of pulse oximeter and handheld Doppler equipment for arterial occlusion pressure measurement in blood flow restriction, finding that pulse oximeter results were reliable. Therefore, in BFR practice, using portable pulse oximetry to measure AOP may be more convenient and cost-effective.

Summary: Low-intensity resistance exercise combined with blood flow restriction exercise affects arterial stiffness in humans. Acute LIRE-BFR may have both positive and negative effects on arterial stiffness in young healthy individuals, while longitudinal studies show no significant changes in arterial stiffness in young and older people.

Summary: There is scientific evidence that Blood Flow Restriction (BFR) is beneficial in patients with neurological disorders, showing improvements in sensorimotor function, gait-related measures, fatigue, and other outcomes. However, the limited number of articles and heterogeneity of the studies call for more robust clinical trials to homogenize protocols and improve methodological quality.

Summary: Blood flow restriction training (BFRT) is a critical tool in rehabilitation medicine, athletic, and clinical populations, but it can also have adverse effects, especially for individuals with cardiovascular diseases. To ensure safe use of BFRT, a risk stratification questionnaire is recommended to assess potential risks and provide appropriate recommendations and referrals.

Summary: The study examines how individuals in the United States use BFR/KAATSU devices and administer BFR/KAATSU training, as well as the safety considerations involved. The findings show that individuals from various professions use a range of devices for BFR/KAATSU training, with different parameters applied to populations with and without defined efficacy.

Summary: The study found that body position significantly affects upper limb arterial occlusive pressure, with seated position showing higher pressure compared to supine position, and supine position showing higher pressure compared to standing position. The method used demonstrated excellent inter-rater reliability and repeatability between different days.

Summary: This study measured arterial occlusion pressure (AOP) in the dominant and non-dominant legs of males and females using different cuff inflation protocols. The results showed no significant differences in AOP within or between the legs, or between sexes. AOP measurements were highly reliable, and the choice of cuff inflation protocol was a matter of personal preference. It is important to measure AOP in both limbs to ensure safe and effective use of blood flow restriction (BFR) during exercise.

Summary: This systematic review examined the efficacy of blood flow restriction in cancer survivors. The results showed that it can improve various factors such as quality of life, physical function, strength, and lean mass, and reduce postoperative complications and hospital stay.

Summary: BFR training shows positive effects on quadriceps strength and CSA in patients undergoing ACL reconstruction and suffering from KOA, but has less significant impact on pain perception, function, and quality of life. Further research is needed to confirm its efficacy.

Summary: The study aimed to validate a handheld Doppler (HHDOP) device for measuring arterial occlusion pressure (AOP) of the brachial and femoral arteries. The results showed no differences in limb circumference or volume in males and females, or between dominant and non-dominant limbs. The differences between HHDOP and gold standard Doppler measurements of AOP were either not significant or had little practical importance. HHDOP can be used by practitioners for safe and effective blood flow restriction.

Summary: Blood flow restriction training shows significant improvements in muscular strength, hypertrophy, and endurance; when compared to high-intensity training, low-intensity BFR training is more effective in a similar low-intensity protocol.

Summary: This study compared the acute effect of traditional resistance exercise (TRE) and low-intensity blood flow restriction (LIRE-BFR) on arterial stiffness in older people with slow gait speeds. The results showed that both TRE and LIRE-BFR had similar responses regarding hemodynamic parameters and pulse-wave velocity.

Summary: Higher retinal vascular resistance, indicating stiffer retinal vessels, is associated with faster functional loss in glaucoma. This finding suggests that tissue stiffening plays a role in glaucomatous damage.

Summary: This study investigated the effects of low-intensity resistance training combined with moderate blood flow restriction on muscle strength and size in patients early after cardiac surgery. The results showed that KAATSU RT can safely increase skeletal muscle strength and size, with improvements in muscle thickness, walking speed, and knee extensor strength.
