A subject’s maximum voluntary contraction (MVC) is recorded and used to normalize both reference forces and results between subjects. [1] During the test subjects are assisted in producing a reference force using various types of feedback (static weight or visual display of force generated).
For the knee extensors, old adults produce less torque during dynamic or isometric maximal voluntary contractions than young adults. The mechanisms controlling fatigue in the elderly during isometric contractions are not the same as those that influence fatigue during dynamic contractions, while young adults keep the same strategy.
To test the reflex, the muscle should be in a neutral position. The muscle being tested needs to be flexed for the clinician to locate the tendon. After the muscle is relaxed, the clinician strikes the tendon. The response should be contraction of the muscle. If this is the knee jerk reflex, the clinician should observe a kick.
The Vogel conflict test (VCT) is a conflict based experimental method primarily used in pharmacology. It is used to determine anxiolytic properties of drugs. The VCT predicts drugs that can manage generalized anxiety disorders and acute anxiety states.
The tests, an early form of psychological testing, assessed candidates based on their proficiency in topics such as civil law and fiscal policies. [12] Early tests of intelligence were made for entertainment rather than analysis. [13] Modern mental testing began in France in the 19th century.
Repetitive nerve stimulation is a variant of the nerve conduction study where electrical stimulation is delivered to a motor nerve repeatedly several times per second. By observing the change in the muscle electrical response (CMAP) after several stimulations, a physician can assess for the presence of a neuromuscular junction disease, and differentiate between presynaptic and postsynaptic ...
Generally, repeated contraction of the muscle can alleviate the myotonia and relax the muscles thus improving the condition, however, this is not the case in paramyotonia congenita. This phenomenon is known as the "warm-up" reflex [8] and is not to be confused with warming up before exercise, though they may appear similar. Individuals with the ...
Exposure therapy is a technique in behavior therapy to treat anxiety disorders. Exposure therapy involves exposing the patient to the anxiety source or its context (without the intention to cause any danger). Doing so is thought to help them overcome their anxiety or distress.
