the effectiveness of TENS is dependent upon the duration,
frequency and amplitude of the stimulating current and
the site of application of the electrodes[1]. There are many
studies where these three variables are different. TENS can
be administered by either dermatomal stimulation or by
stimulation of acupuncture points for labour analgesia[2].
While most studies conclude that TENS does reduce
the pain of labour, a recent Cochrane database review
suggested that the evidence was weak. However, they
stated that it was safe and there was no adverse effect on
the mother and baby[3].
