Biofeedback therapy and hypnotherapy, two sides of the same coin?

Biofeedback therapy and hypnotherapy are actually very similar - the only apparent difference is the medium by which information is gathered.

Wikipedia defines hypnotherapy as "hypnotherapy is an alternative curative healing method that is used to create subconscious change in a patient in the form of new responses, thoughts, attitudes, behaviours or feelings. It is undertaken with a subject in hypnosis." 

And biofeedback therapy as "biofeedback is the process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at will. Some of the processes that can be controlled include brainwaves, muscle tone, skin conductance, heart rate and pain perception.

Biofeedback may be used to improve health, performance, and the physiological changes that often occur in conjunction with changes to thoughts, emotions, and behaviour. Eventually, these changes may be maintained without the use of extra equipment, for no equipment is necessarily required to practice biofeedback."

WebMD states "the idea being that by harnessing the power of the mind and becoming aware of whats going on inside your body, you can gain more control over your health.".

Like hypnotherapy, researchers do not know exactly how biofeedback works - although they know it promotes relaxation which alleviates a number of stress related conditions.

Although biofeedback uses technology to read a client's stress reactions such as heart rate, breathing rate and skin tone - a good hypnotherapist can do exactly that just by paying attention to the client during a session.

Both hypnotherapists and biofeedback therapists are then able to teach their client relaxation techniques to control their bodies responses to the triggering stimuli.

Yet biofeedback therapy is given way more credence than hypnotherapy - the question being, would being hooked up to various monitoring equipment make the client more uneasy and triggered?
