Q.1 The biofeedback device is a therapy which is driven by sensors. It is attached with the body
to evaluate the body functions. The primary focus of the therapy is to train how to combat stress
by means of relaxation process. Person can consciously handle body’s involuntary functions,
heart rate, and breathing so that the person can dominate against stressful condition (Pinter et al,
2019).
Q.2 The common methods that are followed in biofeedback are –
Electromyography (EMG) evaluates muscle tension that varies time to time.
Thermal EMP examines altered body temperature over time.
Electroencephalography evaluates brain wave activity.
Electrocardiogram is used to monitor the heart rate and its variation over time.
Q.3 Biofeedback mainly focuses on the stress related events most. Some examples of this are
eating disorders, learning disorder, muscles spasms, and urine incontinence. It serves other
several problems like asthma, high blood pressure, chronic pain, Raynaud’s disease, and stress or
anxiety disorder. It helps to treat these conditions that are noninvasive and independent of
medicines.
Q.4 The biomed validates the biofeedback’s sounds and value is altered with the specific
processes. In elaboration, it can be stated that biofeedback sensor is attached with the patient’s
body and then it creates a sound and show the variation on the monitor.

Q.5 The specific tests that a biomed performs on the biofeedback unit during pulse modification
include temperature biofeedback and electrocardiogram. In these tests, the signal is transmitted
in the form of pulse. In pulse modulation, continuous signals are sampled at regular intervals.

Q.1 The main purpose of the diathermy is to provide relief to the people suffering from back
pain, muscle strains, arthritis, and inflammation. It uses a high frequency electric current
prescribed for muscle and conditions. It triggers deep heat into the tissue at the time of
continuous application.
Q.2 The actual meaning of diathermy is “heating through” which was first coined by a German
Physician. The diathermy means the heat generation in the tissue by radiation, electric currents.
Q.3 The short wave diathermy is preferred over ultrasound when there is an additional
requirement of heat application in broader terms. Shortwave diathermy applies high
radiofrequency electrical currents in treatment procedures. Shortwave diathermy is a technique
that is used for healing deep muscle tissue for healing pain meanwhile the ultrasound is used
only for tissue that is 2 cm below epidermal tissues.
Q.4 A visual inspection is performed to confirm the monitor whether there is any breakage or
not. Then investigate all the systems are performed correctly or not. After that output control is
examined in different power settings like highest, lowest. At the time of testing, the timer is
checked, then the safety switch whether it is audible or not and finally the whole system is
examined if it is electrically safe or not.
