Effects of Acupuncture in the Treatment of Dogs with Neurological Sequels of Distemper Virus.

Background: Acupuncture (AP) has been empirically used to relieve post-canine distemper virus (CDV) infection neurological signs in veterinary clinics. Objectives: This clinical study aimed to investigate the effects of AP combined with electroacupuncture (EA) on neurological function in dogs infected by CDV. Methods: Twenty-four CDV-infected dogs with neurological sequelae were recruited to receive weekly AP/EA sections for 24 weeks. Neurological improvements were assessed before each AP/EA session using a modified scoring system. Data were analyzed using the McNemar test, Friedman test, Fisher's exact test, and Kaplan-Meier curves (p < 0.05). Results: Neurological scores improved from seven to 24 weeks after AP/EA treatment compared with pretreatment scores (p < 0.001). Significant improvements were recorded over time for functional limb recovery, cranial nerve deficits, mental status (p = 0.025 - 0.014), and urinary function (p < 0.001). Myoclonus was improved and entirely reversed in 75% and 25% of the dogs, respectively. At the end of treatment, the proportion of dogs with normal proprioception, posture, hopping (p < 0.001), and superficial pain sensation responses (p = 0.004) was greater than pretreatment values. Conclusion: AP/EA therapy promoted significant neurological recovery in CDV-infected dogs and may be considered within the chronic phase of the disease to improve motor and sensory rehabilitation. However, these results are preliminary and must be confirmed by further investigations.

Owner assessment of chronic pain intensity and results of gait analysis of dogs with hip dysplasia treated with acupuncture.

OBJECTIVE To evaluate pain intensity and kinetic variables in dogs with hip dysplasia (HD) treated with acupuncture, carprofen, or a placebo. DESIGN Randomized, controlled clinical study. ANIMALS 54 HD-affected dogs and 16 healthy dogs. PROCEDURES Seven HD-affected dogs were removed from the study. Dogs with HD were treated in a blinded manner for 30 days with acupuncture (once weekly for 5 sessions; n = 15), carprofen (4.4 mg/kg [2.0 mg/lb], PO, q 24 h; n = 16), or placebo capsules containing lactose (1 mg/kg [0.45 mg/lb], PO, q 24 h; n = 16). Dogs were evaluated 2 weeks and immediately before (baseline) and 2, 4, and 6 weeks after the onset of treatment. Owners evaluated the dogs' pain intensity with 2 validated questionnaires and a visual analogue scale (VAS) for pain and evaluated degree of lameness with a VAS for locomotion. Kinetics of the hind limbs were also evaluated. Sixteen HD-free dogs were used to assess the evaluation protocol. RESULTS Owners' assessments revealed that outcomes of the 3 treatments did not differ significantly. The Canine Brief Pain Inventory and VAS pain intensity assessments were decreased from baseline at weeks 4 and 6, respectively, but only in acupuncture-treated dogs. The locomotion VAS values were decreased at week 4 in acupuncture-treated and carprofen-treated dogs. Kinetic evaluation findings did not differ among the groups or over time. CONCLUSIONS AND CLINICAL RELEVANCE Neither acupuncture nor carprofen was significantly different from placebo. Acupuncture and carprofen reduced the degree of subjectively evaluated lameness, and acupuncture was associated with a decrease in validated chronic pain scores.
