Are you tired of muscle cramps?
According to The Journal of Manual & Manipulative Therapy, 2006,
“Spasms can be defined as electromyographic (EMG) activity as the result of increased neuromuscular tone of the entire muscle, and they are the result of nerve-initiated contractions.”
In short, a spasm is a muscle contraction or cramp. Typically the spasm will encompass the entire muscle fiber rather than just a bundle of cells.
The onset of a spasm is usually sudden and will often cause lack of control within that area and even a double-over effect. Spasms may last only moments but could cause disability for days.
The journal also explains Myofascial Trigger Points (MTrP),
“a hyperirritable spot in skeletal muscle that is associated with a hypersensitive palpable nodule in a taut band”
