2. TENS DEFINATION:
Tens stands for transcutaneous electrical nerve stimulation
TENS is the application of a pulsed rectangular
wave current via surface electrodes on the
patient’s skin
3. PARAMETERS:
1. Pulse shape or waveform
2. Pulse width or duration
3. Frequency or rate
4. Intensity or amplitude
4. PARAMETERS:
There are 4 parameters
PULSE SHAPE rectangular
PULSE WIDTH 50 – 300 micro seconds
FREQUENCY 2 – 600 HZ (usually 150 HZ )
INTENSITY 0 – 60 mA
6. PLACEMENT OF ELECTRODE :
Acupunture points
Trigger point , motor points
Dermatomes , Spinal segments
Areas with greatest pain intensity
Peripheral nerves
May be horizontal or vertical
Crossed or un crossed
7.
8. High tens
(common parameter)
• FREQUENCY: 100- 150 Hz
• PULSE WIDTH: 100 -500 μs
• INTENSITY : 12 -30 mA
Low tens
(less common parameter)
• FREQUENCY : 1 – 5 Hz
• PULSE WIDTH: 100 – 150 μs
• INTENSITY : 30 mA
9. USES OF TENS:
relief of acute and chronic pain
Angina pectoris
Neck and back pain
Knee pain
Sports injuries
Arthritis
10. TREATMENT:
1. Single treatment session of max 40 mins daily
2. pt stay connected with portable tens ( the unit is on when required )
11. DANGER OF TENS :
Electrolyte reaction below the electrodes-
(high frequency(high TENS),long duration)
CONTRAINDICATIONS :
TENS is contraindicated in
The region of a cardiac pacemaker
Neurological conditions
Malignancy
Carotid sinus (in front of neck)
Active infections , skin conditions
