|Several therapeutic modalities involving energy are used in physiotherapy settings. More specifically, numerous forms of energy including electromagnetic energy, thermal energy, electrical energy, sound energy, and mechanical energy are relevant in terms of therapeutic modalities. Different modalities are used to help treat the individual by strengthening, relaxing and or healing the muscles. For example, in terms of electrical energy, an electrical signal is sent to an injured muscle to help stimulate the muscle. Over the past several years, electrotherapy has become a common practice in physical therapy. The variety in the treatment parameters, such as: the frequency, program duration, pulse width/duration etc. make it difficult to determine the most effective type of muscle stimulation.
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
