Blood Flow Restriction Flashcards
What is BFR
A pt engages in low intensity high repetition resistance training, while wearing a tourniquet around the proximal part of the extremity in order to create a hypoxia environment
What are some physiological mechanisms behind BFR
Lactate production
Muscle activation
Growth hormone
IGF 1 and satellite cells
Myostatin
Mammalian target of rapamycin
What does lactate do to muscle activation
Increase it
Motor unit firing is affected by what
force speed of contraction and oxygen availability
What is downregulation of myostatin
Downregate the protein so muscle hypertrophic happens
What are the proposed benefits of BFR
Increased strength and hypertrophy
Increased aerobic capacity
Positive tendon adaptations
Increased bone turnover
Pain relief/ analgesia
What are grown hormones
Augumented by hydrogen ion and lactate accumulation
Wha are IGF-1
Stimulated by GH and has a hypertrophic role to fuse satellite cells into existing muscle fibers
What is the pathway responsible for muscle protein synthesis
Mammalian target of rapamycin complex 1
What are the targeted patient population for BRF
Injured athlete
Middle aged individuals
Geriatric population
Neuromuscular population
Patients with cardiac conditions
Patients with amputations
What are safety concerns for BRF
DVT formation
Muscle damage (rhabdomyolysis)
Paresthesias
Syncope and anxiety
What are precautions of BFR
Scaly skin
Dry nails
Varicose veins
Obese
Taking anti-hypertensive meds
Diabetes
HTN
Sickle cell trait
Renal compromise
Tumor
Arterial calcification
What are contraindications of BFR
Impaired circulation
Sickle cell anemia
Extremity infection
Dialysis
Increased ICP
elbow surgery
Vascular grafting
Venous thromboembolism
Cancer
What is billing for BFR
BFRT allows PTs to bill for therapeutic exercises, no specific code
Is certification for BFR required
Not required but recommended
