Objective To compare the application value of five tests in behavior assessment of amyotrophic lateral sclerosis transgenic mice.Methods This study included the model group(SOD1-G93A transgenic mice) and negative control group(littermate negative control).Behavioral changes were evaluated by five behavioral assessments(assessment of general condition,weighing,rotarod test,grip strength measurement and step length analysis).Results(1) Assessment of general condition: The general condition of the model group began to decline at day 89.The differences between negative control group and model group began to be significant on day 101,P=0.000.(2) Weighing: Weighing of the model group began to decline at week 15(day 105),and the differences between negative control group and model group became significant,P=0.026.(3) Rotarod test: The time of rotarod test began to decline at week 11(day 77).In week 13(day 91),the differences between negative control group and model group became significant,P=0.047.(4) Grip strength measurement: Grip strength for the hind limbs began to decline at week 10(day 70).In week 13(day 91),the differences between negative control group and model group became significant,P=0.000.(5) Step length analysis: Step length for hind limbs began to decline at week 14(day 98).In week 15(day 105),the differences between negative control group and model group became significant,P=0.000.Conclusion Grip strength measurement is better than the other four behavioral tests in the assessment of behaviors in SOD1-G93A transgenic mice.
