Spontaneous Locomotor Functions
When assessing potential side-effects of investigational compounds, the evaluation of motor function is crucial. Many behavioral tests depend on locomotor activity and animal performance can be influenced by the changes in activity levels. Therefore, it is important to know baseline effects of compounds (or genetic manipulation) on locomotion and related motor functions for proper interpretation of the results. Creative Bioarray offers standard assays for evaluation of locomotor activity for evaluation of motor function.
Fine motor skills' impairment is used as an early marker for diagnosis in muscular degenerative and neurodegenerative diseases. In order to effectively test therapeutic compounds in animal models, it is imperative to characterize the relevant neurodegenerative and muscular degenerative mouse models for fine motor impairment. However, there are limited instruments and assays available to test animal models for fine motor impairment.
