Quantitative motor unit action potential analysis of supraspinatus, infraspinatus, deltoideus and biceps femoris muscles in adult Royal Dutch sport horses

REASONS FOR PERFORMING STUDY: Reference values for quantitative electromyography (QEMG) in shoulder and hindlimb muscles of horses are limited. OBJECTIVES: To determine normative data on QEMG analysis of supraspinatus (SS), infraspinatus (IS), deltoideus (DT) and biceps femoris (BF) muscles. STUDY DESIGN: Experimental observational study and retrospective case series. METHODS: Seven adult healthy Royal Dutch sport horses underwent quantitative motor unit action potential analysis of each muscle using commercial electromyography equipment. Measurements were made according to published method... Mehr ...
