The relationship between urethral sphincter mechanism incompetency and lower back pain: Positing a novel treatment for urinary incontinence in dogs.

Background: In humans, multiple researchers have not only determined that there is a relationship between urinary incontinence (UI) and lower back pain (LBP), but that by treating the LBP, clinicians are able to improve or resolve the UI. Up until now, no equivalent canine research has investigated whether treatment of LBP can improve the clinical signs of acquired, non-neurologic UI in dogs. Aim: To determine if a relationship exists between LBP and urethral sphincter mechanism incompetence (USMI) in dogs. Methods: Review of medical records of all patients that presented to Points East West Veterinary Services with a history of naturally occurring acquired UI from May 2013 to December 2019. Thirty-nine patients treated for LBP using combined acupuncture and manual therapy, and 33/39 patients that also received concurrent photobiomodulation (PBM) therapy, qualified for this study. Results: Treated patients showed a statistically significant reduction in both the frequency (p < 0.01) and volume (p < 0.01) of UI episodes. Treatment responses ranged from no improvement, to complete resolution of the USMI clinical signs. Conclusion: The reduction of USMI clinical signs following LBP treatment suggests a relationship between these two conditions. Combined acupuncture, manual therapy, with or without PBM was shown to be an effective treatment for USMI. By corollary, USMI incontinence should be considered a potential pain symptom.

Effect of age, sex and body weight on the serum concentrations of cobalamin and folate in cats consuming a consistent diet.

Objectives Multiple feline diseases involving the gastrointestinal tract, pancreas, liver and biliary tract are known to cause abnormal serum cobalamin and folate concentrations. Measuring the serum concentration of these vitamins can therefore be a helpful diagnostic tool. However, factors other than disease, in particular age, have also been suggested to have an effect on the serum concentration of cobalamin and folate. In previous studies, the dietary intake was not standardised, or even known, despite diet being the prinicpal source of both vitamins. Therefore, we evaluated the effect of age, sex and body weight on the serum concentration of folate and cobalamin in cats fed the same diet. Methods The serum cobalamin and folate concentrations were measured in 65 apparently healthy cats in a nutrition colony that had been fed an identical diet. A linear model was used to test the relationship between the serum concentration of cobalamin and folate with the variables age, sex and body weight. Results There was a large variation in the serum concentration of both folate and cobalamin, despite identical intake. Serum cobalamin was inversely associated with age ( P = 0.002), and males had higher concentrations than females ( P = 0.039). Serum folate was positively associated with age ( P = 0.01). Conclusions and relevance Independent of diet, serum cobalamin concentration decreases with age. Changes in gastrointestinal function, microflora or metabolism may be responsible. Older cats may be more susceptible to cobalamin deficiency secondary to inappetence or gastrointestinal disease.

Effectiveness of combined acupuncture and manual therapy relative to no treatment for canine musculoskeletal pain.

Despite the rise in popularity of both acupuncture and manual therapy in veterinary medicine, and the increasing number of Canadian veterinarians practising these techniques, there is little research demonstrating their effectiveness. In this repeated measures, therapeutic trial, 47 client-owned dogs with naturally occurring lameness were assessed for clinical response to treatment. Owners were blinded to the treatment schedule and completed questionnaires to assess their dogs' comfort and mobility. Comparison between pre- and post-treatment results demonstrated that combined acupuncture and manual therapy provides immediate short-term improvement in comfort and mobility, as demonstrated by owner observed changes in play behavior (P = 0.015), walking (P < 0.001), trotting (P = 0.002), jumping (P < 0.001), descending stairs (P = 0.003), rising from a lying position (P < 0.001), and reduced stiffness after rest (P < 0.001) or following exercise (P < 0.001). Mood and attitude also improved, but did not attain statistical significance.

Efficacité de l'acupuncture et de la thérapie manuelle combinées par rapport à l'absence de traitement pour la douleur musculo-squelettique canine. Malgré la croissance de la popularité de l'acupuncture et de la thérapie manuelle en médecine vétérinaire et le nombre grandissant de vétérinaires canadiens qui pratiquent ces techniques, il existe peu de recherche démontrant leur efficacité. Dans cet essai thérapeutique à mesures répétées, 47 chiens appartenant à des clients atteints de boiterie naturelle ont été évalués pour leur réponse clinique au traitement. Les propriétaires n'ont pas été informés du calendrier de traitement et ils ont rempli des questionnaires afin d'évaluer le confort et la mobilité de leurs chiens. La comparaison entre les résultats avant et après le traitement ont démontré que l'acupuncture et la thérapie manuelle combinées offraient une amélioration immédiate à court terme pour le confort et la mobilité, comme le démontrent les observations faites par les propriétaires pour le comportement de jeu (P = 0,015), la marche (P < 0,001), le galop (P = 0,002), le saut (P < 0,001), la descente d'escaliers (P= 0,003), le lever d'une position couchée (P < 0,001) et une raideur réduite après le repos (P < 0,001) ou après de l'exercice (P < 0,001). L'humeur et l'attitude se sont aussi améliorées, mais sans atteindre une importance statistique.(Traduit par Isabelle Vallières).

Pressure algometry measurement of canine muscular pain near the thoracolumbar junction: evaluation of a modified technique.

OBJECTIVE: To evaluate the utility of pressure algometry for measuring muscular pain in dogs by using a modified technique intended to prevent the development of a learned apprehension response. STUDY DESIGN: Prospective randomized clinical trial. ANIMALS: Sixty-three client-owned dogs with a history of restricted comfort or mobility. METHOD: Pressure algometry was used to measure the mechanical nociceptive threshold (MNT) in eight locations around the thoracolumbar junction. Dogs were assigned to one of two groups: group A dogs (n = 22) were placed on a restricted exercise program, while group B dogs (n = 25) were placed on a restricted exercise program and were administered combined acupuncture and manual therapy treatment (CAMT). After data collection in groups A and B was complete, animals were recruited for a third (control) group, C (n = 16), that had no exercise restriction or treatment. Algometry measurements were performed on four occasions over 28 days using a technique intended to prevent the dogs from developing a learned apprehension response. Measurements from eight locations were pooled and analyzed for changes over time. RESULTS: Increases in MNTs over time at all locations tested were identified in groups A and B. In group C there were no significant changes in MNT or evidence of a learned apprehension response. CONCLUSION AND CLINICAL RELEVANCE: MNTs in dogs without exercise restriction or CAMT were consistently repeatable and unchanged over time, indicating that there was no learned apprehension response to pressure algometry using the modified technique. Therefore, the increasing MNT values with time in dogs administered exercise restriction with or without CAMT suggests improved muscular comfort of the thoracolumbar region. Although further research is needed, use of this modified technique should improve the utility of pressure algometry for measuring muscular pain in dogs.
