Sterile needles were inserted intramuscularly to a depth of 15-20mm until an unusual (De-Qi) sensation developed and remained inserted for 30-60 minutes and were manually manipulated during this time. The following bilateral acupoints on the hands and feet at Hegu (LI 4), Sanyinjiao (Sp 6) Kunlun (BL 60) and Zhiyin (BL 67)were used.

Sterile needles were inserted intramuscularly to a depth of 15-20mm until an unusual (De-Qi) sensation developed and remained inserted for 30-60 minutes and were either electronically simulated withm2 Hz pulses of 0.5 msec duration for 30 minutes sufficient to cause non-painful muscle contractions. The following bilateral acupoints on the hands and feet at Hegu (LI 4), Sanyinjiao (Sp 6) Kunlun (BL 60) and Zhiyin (BL 67)were used.

Sterile needles were inserted adjacent to the specific acupuncture sites identified for the manual and electro groups to a depth of 1-1.5mm only and insufficient to provoke an unusual sensation and left in position for a 30-60 minutes. Those randomised to 'sham-manual' received no stimulation and those randomised to 'sham-electro' were connected to the electrical stimulator but the current not activated.

Following randomisation to be control group, no specific treatment was organised at this time.

The description of the acupuncture, whether manual, electro or sham, is as described for each of the individual groups.
