stimulation (stim?yu-la'shon) [L stimulare, to goad]
1. An irritating or invigorating action of agents on muscles, nerves, or sensory end organs by which excitation or activity in a part is evoked.
2. A stimulus.
In pregnancy, nipple rolling or the application of heat to the breasts to elicit release of endogenous oxytocin and to generate uterine contractions. The procedure also has been used to evaluate placental sufficiency in the third trimester and to increase contractions in patients with ruptured membranes and when contractions are absent, rare, irregular, or of poor quality. See: oxytocin challenge test
A treatment for patients with mild dementia, in which patients are exposed to and tasked with mentally challenging exercises to improve their ability to think and interact effectively with their environment and with other people. It is used as an adjunct to medical therapy, often in a recreational setting, to make the activity fun and socially engaging. Synonym: psychostimulation
deep brain stimulation
The application of pulsed electrical energy via electrodes to the pars interna of the globus pallidus or the subthalamic nucleus. It is used to treat movement disorders, such as Parkinson disease.
dorsal cord stimulation
The relief of pain with electric stimulation of the posterior spinal cord.
double simultaneous stimulation
In a neurological examination, a test of unilateral neglect. A light touch, audible signal, or visual cue is provided to both sides of the patient at the same time, e.g., both arms, both ears, both the left and right visual fields. Failure to detect one of the stimuli suggests a lesion in the opposite side of the cerebral cortex. Double simultaneous stimulation can also be performed on one side of the body, for instance, by tapping the left arm and left side of the face at the same time. If the distal stimulus is undetected even after several trials, the patient may have an organic brain syndrome.
electrical stimulation Abbreviation: ES
The use of electric current to affect a tissue, e.g., nerve, muscle, or bone. The stimulation of bone, for instance, facilitates and hastens the healing of fractures. Synonym: electrostimulation; electrotherapy See: bipolar (2); monopolar; transcutaneous electrical nerve stimulation
fetal acoustic stimulationVibroacoustic stimulation (of the fetus).
fetal scalp stimulation
An assessment of fetal well-being in which the examiner reaches into the vagina and rubs the scalp of the fetus. The fetal heart rate is monitored for accelerations. If the fetal heart rate does not accelerate appropriately, further testing, such as scalp blood sampling, may be needed.
fetal (vibratory) acoustic stimulation Abbreviation: FAST
A noninvasive means of assessing fetal reactivity during labor. It typically is used as an adjunct to nonstress testing. The examiner applies an electronic source of low-frequency sound (such as an electrolarynx) firmly to the mother's abdomen over the fetal head. A reactive test is characterized by fetal heart rate accelerations or other measurable forms of increased fetal activity.
The use of various techniques to provide neonates and infants identified with or at risk for developmental delay with an environment that has a rich and diverse range of sensations and experiences.
intramuscular stimulation Abbreviation: IMS
The insertion of solid needles into sensitive or painful body parts in order to alleviate musculoskeletal, myofascial, or nerve pain. Synonym: dry needling; trigger point dry needling. See: trigger point.
magnetic cortical stimulation
The induction of painless electrical current within the brain to detect abnormalities in cortical motor neuron function.
The activation or energizing of a nerve, through an external source.
Massaging or suckling the nipple of the breast and surrounding aureola to stimulate uterine contractions or induce labor.
A treatment for female infertility that encourages the ovaries to produce and release more eggs than they normally do during each monthly cycle.
percutaneous electrical nerve stimulation Abbreviation: PENS
A treatment for pain in which weak electrical currents are applied to acupuncture needles inserted into trigger points or dermatomes near painful body parts. PENS is sometimes used to treat episodic low back pain and other regional pain syndromes. It may be used as an alternative to transcutaneous electrical nerve stimulation (TENS).
Russian electrical stimulation
The application of surface electrodes on a muscle with the intent of strengthening the muscle. The patient may perform physiologic muscle contractions while simultaneously using the muscle stimulation.
percutaneous tibial nerve stimulation
A treatment for urinary urgency, urge incontinence, and possibly chronic pelvic pain, in which electrical stimulation is applied by a pulse generator to the tibial nerve in the leg.
transcranial magnetic stimulation Abbreviation: TMS
The application of pulses from a magnetic coil to induce electrical currents in specific parts of the brain. This treatment has been used in experimental neuroscience to study the activity of different areas of the brain, and in psychiatry as a noninvasive alternative to electroconvulsive therapy.
TRANSCUTANEOUS ELECTRICAL NERVE STIMULATION
transcutaneous electrical nerve stimulation Abbreviation: TENS
The application of mild electrical stimulation through electrodes placed on the skin over a painful area. It alleviates pain by interfering with transmission of painful stimuli. See: illustration
vagus nerve stimulation
A treatment for seizures and treatment-resistant depression in which a generator sends electrical impulses along the left vagus nerve. The impulse generator is typically inserted under the clavicle on the left side of the chest during a brief surgical procedure. The device is set to generate electrical impulses of appropriate amplitude, frequency, and pulse width to control a patient's symptoms.
vibroacoustic stimulation (of the fetus)
A test of fetal responsiveness during pregnancy. A transducer is placed on the mother's abdomen, into which the transducer emits an oscillating sound. The fetal response is measured. Synonym: fetal acoustic stimulation
Patient discussion about stimulation
Q. How does a Transcutaneous electrical nerve stimulation (TENS) unit help fibromyalgia. My aunt was suggested to go through TENS. Will that really help? How does a Transcutaneous electrical nerve stimulation (TENS) unit help fibromyalgia?
A. ‘TENS’ units are prescribed for chronic pain sufferers and fibromyalgia patients. What is a tens unit? Tens stands for Transcutaneous electrical nerve stimulation. A tens unit is essentially a stimulation device consisting of electrodes that are attached to the skin, the unit itself, and a battery to provide current. A Tens unit uses electricity to block nerves from sending pain messages.
Q. Can some depression be treated with stimulantes in adults?? I was treated with dextroamphetimins in the 1970's. Why arent they used anymore? I know all of the things about addiction, so I dont need those answers. When the medication was used by me, it worked. My husband is suffereing from depression he has been given all of the "wonder" drugs No results. I hope someone can answer this for me, and for my husbands sake
A. Thank you BLars. I am going to talk to my husbands doctor when we have our appointment tomorrow..I get so tired of all of the experts who wont prescribe the right medications because of the abuse potential..CNS Stimulants were used before, and all of us that were on them when we needed them arent worse for wear..I am glad adderall is helping you.Maybe people like us need to speak out, so other patients arent afraid to ask their doctors..Have a great week!!More discussions about stimulation
