Clinical Trial Summary
It is an interventional study in which 60 obese elderly patients (30 male & 30 female)
estimated to enroll according to random allocation and divided into two groups. The study
group will receive active acupuncture low level laser in addition to nasal laser irradiation
and aerobic exercises while the control group will aerobic exercises. The laser consists of a
semiconductor and operates at a wavelength of 650 nanometre. The laser installed in the watch
comprises 10 individual laser beams for the wrist and an additional adapter for nasal
stimulation. The output power is 5 megawatt, but it can also be adjusted. The device operates
at an ambient temperature of -20 to +40 ° C and a relative humidity of ≤ 85%. The laser watch
can be used for a variable irradiation period of 10-60 min. the device will be applied on
specific acupuncture points ( acupuncture point, Radial artery acupuncture points, and ulnar
artery acupuncture points) combined with nasal laser irradiation at the same time, once per
day, 3 times per week for three months
Description:
PURPOSE:
To determine whether low level laser light therapy is effective as an adjunctive therapy on
countering hypercoagulable state parameters (fibrinogen, bleeding time, Prothrombin time) and
total cholesterol (, d-dimer and c-reactive protein) as preventive strategy of venous
thromboembolism incidence in obese elderly patients
BACKGROUND:
In the general population the annual incidence of venous thrombosis (VT) approximates 1 in
1000 persons and appears to be increasing over time. Notably, incidence rates rise
exponentially with age with an approximate 7- to 10-fold increase from less than 55 years to
greater than 75 years. Aging is associated with increased levels of coagulation factors and
decrease in natural anticoagulant factors. This strongly supports that age-related
hypercoagulable state occurs in elderly.
Blood coagulation plays a critical role not only in homeostasis but also in many
physiological and pathological conditions. Blood coagulation potential in humans reaches a
young adult level around the time of weaning, followed by a gradual increase during young
adulthood and an almost 2-fold increase by old age.
Fibrinogen may contribute to the cardiovascular risk due to their influence on blood
viscosity, platelet aggregation, low-density lipoprotein deposition, blood vessel diameter
and cell proliferation. Most of the factors that cause venous thromboembolism are related to
changes in blood flow and changes in the composition of the blood.
In recent years, an innovative technology using low-level laser light has garnered an
exceptional level of interest across myriad medical disciplines because of its unique ability
to modulate cellular metabolism, therefore inducing beneficial clinical effects
Low level laser radiation has particular effect on blood viscosity by changing the sizes of
erythrocyte aggregates which lead to an increase in the blood flow velocity in the human
body. There are several reasons for the increase in the blood microcirculation under
irradiation. One of the major reasons is the activation of the respiratory chains of cells
leading to a cascade of biochemical reactions that resulting in an increase in the
permeability of erythrocyte membranes and an increase in the concentration of oxygen in the
bio tissues.
HYPOTHESES:
countering hypercoagulable state parameters (fibrinogen, bleeding time, Prothrombin time) and
total cholesterol (, d-dimer and c-reactive protein) as a preventive strategy of venous
thromboembolism incidence in obese elderly patients
RESEARCH QUESTION:
Does low level laser therapy with aerobic exercises influence on obese elderly patients'
hemostatic state parameters as coagulation profile ((fibrinogen, bleeding time, Prothrombin
time) and total cholesterol (, d-dimer and c-reactive protein) as prevention of venous
thromboembolism in the obese elderly patient
