Chinese Acupuncture for Chemobrain in Elderly Cancer Patients

"Disposable acupuncture needles(0.30mm in diameter and 25-40mm in length) will be inserted at a depth of 10-30mm perpendicularly or obliquely into acupoints. Manual manipulation will be carried out for all acupoints to evoke needling sensation. Electrical stimulation was additionally delivered on the 6 pairs of the frontal acupoints. The output peak current and voltage of the machine would be 6V and 48mA, respectively, with constant wave at frequency of 2Hz and phase duration of 100µs for 30min. Electrical stimulation lasted 30min. The needles on body acupoints will be also retained for 30min.~Acupuncture intervention will be conducted for 2 sessions per week over 8 consecutive weeks. The determination of 8 weeks of the treatment duration will be based on the fact that the robust effects of acupuncture in cancer patients will be generally observed within 8 weeks of treatment."
