The exam is based on neurological responses, touch and pinprick sensations tested in each dermatome, and strength of the muscles that control key motions on both sides of the body. [7] Muscle strength is scored on a scale of 0–5 according to the adjacent table, and sensation is graded on a scale of 0–2: 0 is no sensation, 1 is altered or ...
Grade 1: No active range of motion & Palpable muscle contraction only Grade 0: No active range of motion & No palpable muscle contraction Manual muscle testing, however, has a number of limitations. One limitation is that the MRC scale is an ordinal scale with disproportional distances between grades. Another limitation of the MRC scale is that ...
The strength of any given muscle, in terms of force exerted on the skeleton, depends upon length, shortening speed, cross sectional area, pennation, sarcomere length, myosin isoforms, and neural activation of motor units. Significant reductions in muscle strength can indicate underlying pathology, with the chart at right used as a guide.
The severity of muscle weakness can be classified into different "grades" based on the following criteria: [16] [17] Grade 0: No contraction or muscle movement. Grade 1: Trace of contraction, but no movement at the joint. Grade 2: Movement at the joint with gravity eliminated. Grade 3: Movement against gravity, but not against added resistance.
It may be suboptimal functioning of the tested target muscle, or a normally optimally functioning muscle can be used as an indicator muscle for other physiological testing. A commonly known and very basic test is the arm-pull-down test, or "Delta test," where the patient resists as the practitioner exerts a downward force on an extended arm. [ 16 ]

There are three distinct types of muscle: skeletal muscle, cardiac or heart muscle, and smooth (non-striated) muscle. Muscles provide strength, balance, posture, movement, and heat for the body to keep warm. [3] There are more than 600 muscles in an adult male human body. [4]
For example, a person can be high tone with normal to poor flexibility in most areas, but be able to put the palms of the hands on the floor with straight knees due to hypermobile sacroiliac joints. [citation needed] It is important to assess several areas before deciding if a person has high, low, or normal muscle tone. A fairly reliable ...
