Motor Assessment
Rotarod acceleration profiles, treadmill endurance testing, grip strength measurement, and skilled reaching analysis. ConductMaze controls motor speed, records latency to fall, and exports fatigue curves.
Rotarod
The rotarod test is the most widely used assay for motor coordination, balance, and fatigue resistance in rodents.
8 parametersBalance Beam
The balance beam test assesses fine motor coordination and balance by requiring rodents to traverse a narrow, elevated beam to reach an enclosed safety platform.
6 parametersGrip Strength
The grip strength test measures peak forelimb (or combined forelimb and hindlimb) grip force by allowing the animal to grasp a force transducer bar or grid while the experimenter gently pulls the animal away by the tail.
6 parametersGait Analysis
Automated gait analysis systems such as the CatWalk provide a comprehensive, quantitative assessment of locomotor function by recording paw prints as the animal traverses an illuminated glass walkway.
7 parametersPole Test
The pole test evaluates bradykinesia and motor coordination by measuring the time required for a mouse to turn head-downward (T-turn) and descend a vertical pole to the base.
6 parametersWire Hang (Inverted Grid)
The wire hang test (also called the inverted grid or wire suspension test) measures muscular strength and endurance by placing the animal on a wire grid or single wire that is then inverted, forcing the animal to hang by its paws against gravity.
6 parametersTreadmill Endurance Test
The treadmill endurance test is a standardized paradigm for quantifying aerobic capacity and fatigue resistance in rodents.
8 parametersParallel Rod Floor Test
The parallel rod floor test quantifies motor coordination and gait regularity by requiring animals to traverse a platform of evenly spaced parallel rods.
6 parametersSkilled Pellet Reaching Task
The skilled pellet reaching task assesses fine motor dexterity and forelimb function by requiring rodents to reach through a narrow aperture, grasp a small food pellet from an external shelf, and retrieve it to the mouth.
7 parametersCatalepsy Bar Test
The catalepsy bar test measures the inability to correct an externally imposed abnormal posture, a hallmark of extrapyramidal motor dysfunction.
5 parametersAccelerating Rotarod
The accelerating rotarod is the gold-standard apparatus for quantifying motor coordination and balance in rodents, consisting of a rotating cylinder (typically 3 cm diameter for mice, 7 cm for rats) elevated above a platform with individual lanes separated by flanged dividers.
10 parametersConstant Speed Rotarod
The constant speed rotarod protocol maintains a fixed rotation rate throughout the trial, providing a sustained motor endurance challenge that isolates fatigue resistance and tonic postural control from the progressive coordination demands of the accelerating paradigm.
10 parametersRotarod Fatigue Protocol
The rotarod fatigue protocol employs repeated accelerating or constant-speed trials with short inter-trial intervals (typically 60 seconds) to deliberately induce progressive motor fatigue and quantify the rate and magnitude of performance decline across a high-volume session of 10 or more trials.
10 parametersBeam Walk Test
The beam walk test (also called the balance beam test) assesses fine motor coordination and balance by requiring rodents to traverse an elevated narrow beam to reach a dark goal box at the opposite end.
9 parametersFootprint Gait Analysis
Footprint gait analysis provides a detailed quantitative assessment of locomotor patterns by recording paw placement coordinates during continuous voluntary walking along a straight runway.
8 parametersCylinder Test (Forelimb Asymmetry)
The cylinder test (also known as the spontaneous forelimb use asymmetry test) places a rodent in a transparent glass or Plexiglas cylinder and quantifies the relative use of left versus right forepaws during spontaneous vertical exploratory behavior (rearing and wall contact).
8 parametersTremor Analysis
Tremor analysis provides a quantitative, frequency-domain characterization of involuntary oscillatory movements in rodent models of movement disorders.
7 parametersLever Pull
The isometric lever pull task is a precision instrument for measuring forelimb grip force, skilled pulling, and motor learning in rodents.
8 parametersZebrafish Swim Tunnel Performance Test
The zebrafish swim tunnel is a forced-exercise apparatus designed to measure critical swimming speed (Ucrit), aerobic capacity, and endurance in zebrafish by exposing individuals to incrementally increasing water flow velocities within an enclosed swim chamber.
