Clinical Trial Summary
The aim of this research is to determine the effect of blood flow restriction training on
shoulder pain, range of motion, muscle strength and shoulder. Randomized controlled trials
will be done at Lady Reading Hospital Peshawar and Shahab Orthopedic General Hospital. The
sample size is 36. The subjects will be divided in two groups, 18 subjects in BFR group and
18 in no BFR group. Study duration is 6 months. Sampling technique applied was non
probability connivance sampling technique. Tools used in the study are SPADI shoulder score,
NPRS, hand held dynamometer, sphygmomanometer and goniometer.
Description:
Frozen shoulder is painful shoulder condition associated with stiffness and shoulder
disability. It is associated with reduction in forward elevation and marked external
rotation. Frozen shoulder is common condition effecting population between ages 30 to 60
years. Prevalence is more common in women than on men There are four stages of adhesive
capsulitis, stage1, stage 2 (freezing stage), stage 3 (frozen stage) and stage 4 (thawing
stage). Patient have sharp pain at end range of motion, sleep disturbances and early loss of
external rotation. When compared to asymptomatic subjects, patients with adhesive capsulitis
have higher upper trapezius to lower trapezius EMG ratios during arm elevation, indicating a
muscular imbalance. The scapula eventually migrates upward before 60 degrees of abduction in
individuals with adhesive capsulitis, resulting in the recognizable "shrug sign" during
shoulder elevation.
Blood flow is restricted in a controlled form of vascular occlusion using external
tourniquet. A recent study demonstrated that augmentation of low load resistance with blood
flow restriction (L-L BFR) to contractile tissue can produce hypertrophy and strength gains,
using loads as low as 30% 1RM. BFR exercise may stimulate skeletal muscle growth and strength
gains through a number of different methods. These could include an increase in hormone
levels, an increase in the motor pathway or other intracellular signaling pathways for muscle
protein synthesis, an increase in satellite cell activity biomarkers, and apparent patterns
in fibre type recruitment.
The purpose of this study is to provide the effects of blood flow restriction training on
shoulder discomfort, range of motion, muscle strength and disability in patients with
adhesive capsulitis. Due to pain and decrease range of motion individual with adhesive
capsulitis experience muscle weakness in shoulder joint. Blood flow restriction training has
positive effect on improvement of muscle strength and range of motion in shoulder region.
Blood flow restriction training has also positive effect on bone healing and bone density.
Therefore the study is aimed to improve the muscles strength and capsule inflammation in
individual with adhesive capsulitis.
