      - 1.Traditional TENS
        (Hi TENS, Normal TENS)
        
        High frequency may be defined as being
        greater than 50 Hz.
        
        The International Association for the Study of Pain (IASP)
        describes conventional TENS as
        
        “High-frequency (50–100 Hz),
        
        low-intensity (paraesthesia, not painful),
        
        small pulse width (50–200μs)
        
        high frequency (80 - 130Hz)
        and employ a
        
        relatively narrow (short duration) pulses (200μs).
        
        ‘strong but comfortable’.

        Limited ‘carry over’ effect
        (short lasting effect)

        AcuTENS)
        
        3.BRIEF INTENSE TENS
        
        a rapid pain relief
        
        The pulse frequency applied is high
        (in the 80-130Hz band)
        and the pulse duration (width)
        is also high (200μs plus).
        
        The current is delivered at,
        or close to the
        tolerance level for the patient -
        such that they would not want the machine turned up any higher.

        4.BURST MODE TENS
        
        The machine is set to deliver traditional TENS, but interrupting the stimulation outflow
        at rate of 2 - 3 bursts / second.
        
        It can effectively stimulate both
        
        the PAIN GATE and the
        
        OPIOID mechanisms simultaneously.

        5.MODULATION MODE TENS
        
        The machine delivers
        a less regular pattern of TENS stimulation
        in an attempt to
        reduce or minimise the
        accommodation effects of regular, patterned stimulation.

        Low-frequency TENS is consistently defined as being 10 Hz or less.
        
        IASP defines the characteristics of AL-TENS as
        
        “Low-frequency (2–4Hz),
        
        higher intensity (to tolerance threshold),
        
        longer pulse width (100–400μs)”
        
        Lower frequency stimulation (2-5Hz) with
        
        wider (longer) pulses (200-250μs)
        
        Definite, strong sensation
        
        30 minutes will need to be delivered as a minimally effective dose.
        
        The ‘carry over’ effect may last for several hours.
