TENS -uses |
-acute & chronic pain -TMJ pain -post op pain (gate control theory) |
|
|
types of TENS |
1. conventional 2. accupunture-like 3. brief intense 4. noxious |
|
|
contraindications |
-diabetic neuropathy -SCI -hx of angina pectoris -placed on area of sensory impairment can cause burns -pacemaker: TENS can stimulate or inhibit the pacemaker -pregnant: can induce labor -over carotid sinuses (can cause hypotension) -electrodes on ant neck can cause laryngospasm - |
|
|
conventional TENS |
-electrical pulse w/ short duration, high frequency, & low current amplitude (low stimulus intensity) -amplitude high enough to generate sensory response, but not motor response -decrease pain during ADL's -pulse freq.: high 30-150 pps (Hz) -pulse duration: short 50-100 microsec -time: variable -current: 10-30 Hz High stimulation freq Low intensity Current: 10-30 mA |
|
|
acupunture-like TENS |
-longer lasting pain relief -do not use w/ ADL's bc mm twitching generated -electrical pulse w/ long duration & low freq. -amplitude: sufficient for mm twitching -pulse freq: low (2-4 pps) -pulse duration: long (100-300 micro sec) -time: 20-45 mins low freq. stimulus: 1-10 Hz high stimulus intensity close to tolerance of ot |
|
|
brief-intense TENS |
-minimize pain during therapeutic activity -long duration, high frequency, mod current amplitude -amplitude: strong paresthesia or motor response -pulse freq: high (60-200 pps) -pulse duration: long (150-500 micro sec) time: 15 mins |
|
|
Conventional TENS -low or high rate? |
high rate at SC level |
|
|
Low rate TENS & pain control |
-has a stronger stimulus & a longer pulse duration, activates the descending inhibition, stimulating endorphin production mechanisms |
|
|
Pulsed TENS |
-low intensity stimuli firing in high freq bursts -freq of burst: 1-2 Hz -freq of impulses is 100 Hz High freq bursts Low intensity Each burst 100 Hz |
|
|
TENS -when to set the pulse rate? |
-before switching on the machine -place electrodes on skin before turning machine on -pads placed over painful areas -pads should not be w/in 1" of each other -do not use over area of sensory impairment (increased risk of burns) |
