Can Blood Flow Restriction Therapy Improve Strength for Shoulder External Rotators Better Than Exercise Alone

2019-01-29 16:11:12 | BioPortfolio


The purpose of this study is to evaluate the ability of blood flow restriction therapy to improve strength of shoulder muscles during the sidelying external rotation (ER) exercise versus a control group who only performs the sidelying ER exercise.


The purpose of this study is to determine if blood flow restriction (BFR) therapy is superior at increasing strength of the shoulder (supraspinatus, infraspinatus, posterior deltoid, and middle deltoid) and increasing tendon size of the supraspinatus and infraspinatus (as determined by diagnostic ultrasound) while performing the sidelying external rotation exercise compared to those who only perform the sideyling external rotation exercise without BFR.

Subjects will be randomized to one of two treatment groups: exercise with BFR or exercise alone. Recruitment will be a sample of convenience consisting of healthy adults (age range 22 to 45). Subjects will perform the sidelying external rotation exercise 2 times a week for an 8 week period.

The Effects of Resistance Exercise With Blood Flow Restriction on Flow-Mediated Dilation and Arterial Stiffness in Elderly People With Low Gait Speed: Protocol for a Randomized Controlled Trial.

During aging, a significant loss of muscle mass, strength, and power is associated with a decline in daily functional capacities. Traditionally, resistance training is prescribed to prevent or reverse...

Low intensity blood flow restriction exercise: Rationale for a hypoalgesia effect.

Exercise-induced hypoalgesia is characterised by a reduction in pain sensitivity following exercise. Recently, low intensity exercise performed with blood flow restriction has been shown to induce hyp...

Effects of combined treatment with blood flow restriction and low current electrical stimulation on muscle hypertrophy in rats.

The position of the cuff bladder has a large impact on the pressure needed for blood flow restriction.

A recent study suggested that measuring the blood flow restriction pressure every training session may not be needed given the relative stability of this measurement over an eight week period of time....

Medical and Biotech [MESH] Definitions

A group of disorders marked by progressive degeneration of motor neurons in the spinal cord resulting in weakness and muscular atrophy, usually without evidence of injury to the corticospinal tracts. Diseases in this category include Werdnig-Hoffmann disease and later onset SPINAL MUSCULAR ATROPHIES OF CHILDHOOD, most of which are hereditary. (Adams et al., Principles of Neurology, 6th ed, p1089)

A heterogenous group of inherited muscular dystrophy without the involvement of nervous system. The disease is characterized by MUSCULAR ATROPHY; MUSCLE WEAKNESS; CONTRACTURE of the elbows; ACHILLES TENDON; and posterior cervical muscles; with or without cardiac features. There are several INHERITANCE PATTERNS including X-linked (X CHROMOSOME), autosomal dominant, and autosomal recessive gene mutations.

A heterogeneous group of inherited MYOPATHIES, characterized by wasting and weakness of the SKELETAL MUSCLE. They are categorized by the sites of MUSCLE WEAKNESS; AGE OF ONSET; and INHERITANCE PATTERNS.

The amount of PLASMA that perfuses the KIDNEYS per unit time, approximately 10% greater than effective renal plasma flow (RENAL PLASMA FLOW, EFFECTIVE). It should be differentiated from the RENAL BLOOD FLOW; (RBF), which refers to the total volume of BLOOD flowing through the renal vasculature, while the renal plasma flow refers to the rate of plasma flow (RPF).

Maintenance of blood flow to an organ despite obstruction of a principal vessel. Blood flow is maintained through small vessels.
