The Trigger Point Wall Chart Set includes four myofascial Trigger Point charts and a Muscle Movement / Range of Motion chart. Trigger Points are color coded, cross-referenced and listed by Pain Referral Areas. Columns logically organize muscles by compartment, displaying them superficial to deep.

Muscle spasticity is a condition characterized by muscle stiffness in one or more muscles and reduced joint movement, which causes pain and disability. This condition is associated with neurological damage caused by disorders that affect the connections between neurons that control muscle movement (motor neurons) and muscles, such as multiple sclerosis, stroke, traumatic brain injury, cerebral palsy, or spinal cord injury.

The three types of muscle in mammals are:1. Cardiac- (this you learnt about earlier when we did transport in animals)2. Smooth- also known as involuntary muscle as the individual has no control over it.3. Striated- these muscles are attached to the bone and are also called voluntary muscles as they are often controlled consciously. As you can see below, there are striations (stripes) in this muscleThe diagrams above show how the cardiac muscle, smooth muscle and striated muscle looks (respectively).Note: You don’t need to be able to draw these diagrams.How muscles cause movementMuscles contract (get shorter) by using energy from respiration. When they do this, they allow movement to occur. Since muscles vary, the way they contract will also vary. Cardiac muscles are the only muscles in the body that will never tire. They do not need to be controlled by the brain but the brain may alter its rate of contraction.In the walls of the alimentary canal, the smooth muscle operates similarly to the cardiac muscle during peristalsis. In other places, however, the smooth muscle needs to be stimulated by nerves.The following diagram shows the relaxation and contraction of muscles

The Muscle Movement / Joint Range of Motion (ROM) Chart lists by joint the degrees of normal range of motion and the muscles producing each movement. Color-coded columns group joints by body region.
