From: Voluntary movements as a possible non-reflexive pain assay
Voluntary movements of mice with acute visceral pain induced by acetic acid. (A) Acetic acid was administered at 10 mg/kg intraperitoneally. Numbers of writhes were measured over 20 min after the injection of saline or acetic acid (n = 6). (B-C) Voluntary movements were measured in saline or acetic acid treated mice. Acetic acid treated mice showed a significant reduction in number of rearings. (B) and total distance moved (C) (n = 6).
