Methods |
Design: three group parallel trial
Purpose: study the effect of acupressure on chemo‐therapy induced nausea |
Participants |
Patients: cancer patients receiving chemotherapy
Baseline comparability: yes |
Interventions |
Placebo: needling in S13 point theoretically inert for nausea
Untreated: no needling
Experimental: needling in P6
(Co‐intervention: antiemetic drugs) |
Outcomes |
Nausea intensity (NRS)
Rhodes Index of Nausea (3 items)
Rhodes index of nausea and vomiting (1 item)
Functional status (NRS)
State‐Trait Anxiety Inventory |
Notes |
Data provided from authors: mean nausea NRS (0 to 10) evening after getting chemotherapy. |
