Muscle feedback or myofeedback provides insights in movement and posture. Are exercises done as they are intended and does the muscle tension really increase? With myofeedback, the electromyography (EMG) or electrical conduction of muscle fibers is measured with a direct relationship to muscle tension. EMG training is often applied in rehabilitation of muscles that are too relaxed or too tense. By means of EMG biofeedback, the person learns to strengthen or to relax certain muscles in e.g. rehab or temporomandibular disorders.
Biofeedback for pelvic floor muscle retraining is a treatment to help clients learn to strengthen or relax their pelvic floor muscles in order to improve bowel or bladder function and decrease some types of pelvic floor pain. For this training, the person learns to strengthen the rectal sphincter or vaginal muscles. Ideally, this is combined with a measurement of the abdominal muscles. The method is based on the same principle as measuring surface EMG. Biofeedback has had a great impact upon incontinence, due to its ease of use and very high success rate. Although treatment time varies, in most people, continence can generally be restored in 4-8 weeks for both fecal and urinary incontinence by using the techniques described in this protocol, which combine clinical assessment and training with EMG biofeedback.
Biofeedback enables a client to self-regulate the bodily signals and in this way to gain more control over stress levels. Many stress related and attention related disorders can be treated successfully by applying biofeedback training. Biofeedback offers a tool to determine the psychophysiological condition in terms of physiological parameters like breathing, heart rate, muscle tension, temperature, sweating and more. Clients hereby gain more insight in the body-mind connections. Typical applications are burn-out, anxiety, PTSD, chronic pain, headache, insomnia and many stress related disorders.
