The Pole Test is a standardized behavioral apparatus designed to assess motor coordination and movement disorders in rodents. This simple yet sensitive test evaluates an animal's ability to orient and descend from a vertical pole, providing quantitative measures of motor dysfunction commonly associated with nigrostriatal damage and dopaminergic system impairment.
The apparatus consists of a vertical pole with species-specific diameters (8 mm for mice, 10 mm for rats) that allows researchers to measure turning time, total descent time, and movement quality. The test is particularly valuable for evaluating motor phenotypes in Parkinson's disease models, including 6-OHDA lesioned animals and MPTP-treated subjects, where bradykinesia and postural instability are primary endpoints.
*TUB NOT INCLUDED
The pole test exploits the natural tendency of rodents to turn head-down and descend when placed on a vertical pole. Normal animals rapidly orient themselves and descend smoothly, while animals with motor dysfunction exhibit prolonged turning times and hesitant, bradykinetic movements during descent.
The test measures two primary parameters: turning time (latency to orient head-down) and total descent time (time to reach the base). Additional qualitative assessments include movement fluidity, number of slips, and use of alternative descent strategies. These measures correlate with the degree of striatal dopamine depletion and provide a sensitive index of motor impairment.
The apparatus diameter is optimized for each species to ensure appropriate grip difficulty - too narrow causes slipping in healthy animals, while too wide fails to challenge motor-impaired subjects. The standardized dimensions (8 mm for mice, 10 mm for rats) have been validated across multiple Parkinson's disease models.

Background reading relevant to this product:
What training protocol is recommended before data collection?
Conduct 2-3 habituation trials to familiarize animals with the apparatus. This reduces anxiety-related confounds while maintaining sensitivity to motor deficits.
How sensitive is the pole test to partial dopamine depletion?
The test can detect motor deficits with as little as 50-60% striatal dopamine loss, making it suitable for mild to moderate lesion studies.
What are the key timing parameters to measure?
Record turning time (latency to orient head-down) and total descent time. Additional measures include number of slips and qualitative movement assessment.
Can the test distinguish between different types of motor impairment?
Yes, bradykinetic animals show prolonged descent times while animals with postural instability exhibit increased turning times and slipping behavior.
What pole height should be used for standard protocols?
Standard height is 55 cm, providing sufficient descent distance for timing measurements while preventing injury from falls.
How does this compare to rotarod testing for motor assessment?
The pole test is more sensitive to bradykinesia and natural movement patterns, while rotarod primarily measures balance and coordination under forced conditions.

Pole diameter and height change grip mechanics and descent time, so the pole geometry should match the grip span and body size of the species being tested.

View options ->Gauze-wrapped pole surface for maximal grip and reduced slipping
Best when slipping confounds descent time, because a gauze-wrapped high-grip surface isolates turning and descent coordination from grip failure on a smooth pole.

The Pole Test measures bradykinesia and motor initiation by recording how long a rodent takes to turn head-down at the top of a vertical pole and to descend to the base. Ogawa and colleagues introduced the test as a simple quantitative measure of bradykinesia in dopamine-depleted mice. 1
The two core readouts are time to turn, an index of movement initiation, and time to descend, which captures the full turning-and-climbing sequence. Because turning head-down on a narrow pole requires coordinated initiation and postural adjustment, the test is widely used to characterize sensorimotor anomalies in models of striatal dopamine depletion. 1
Pole texture and diameter, training state, body weight, motivation to descend to the home cage, and motor learning all change turn and descent times independent of true motor initiation. A defensible protocol fixes pole geometry and surface, trains animals to a stable head-up start, scores falls and missteps separately, and reports turn-direction bias as a quality-control flag. 1

Limitations of the paradigm, methodological caveats, and current directions.
Variables that shift Pole Test results independent of anxiety state.
Surface texture and diameter set grip and descent difficulty. A smooth pole causes sliding that confounds descent time, so geometry and surface must be held constant.
Untrained animals confound motor initiation with task acquisition. Train to a stable head-up start and reliable turn before testing.
Heavier animals descend differently independent of motor initiation, so weight should be reported and considered when groups differ in mass.
A home cage or familiar enclosure at the base motivates descent. A weak incentive increases stalling and inflates descent time without a true deficit.
Turn and descent times improve across early trials as animals learn the task, so a single session can confound bradykinesia with task acquisition.
## Pole Test — methods controls Confounds controlled in this protocol: - **Pole texture/diameter.** Surface texture and diameter set grip and descent difficulty. A smooth pole causes sliding that confounds descent time, so geometry and surface must be held constant. - **Training state.** Untrained animals confound motor initiation with task acquisition. Train to a stable head-up start and reliable turn before testing. - **Body weight.** Heavier animals descend differently independent of motor initiation, so weight should be reported and considered when groups differ in mass. - **Motivation (home-cage at base).** A home cage or familiar enclosure at the base motivates descent. A weak incentive increases stalling and inflates descent time without a true deficit. - **Motor learning.** Turn and descent times improve across early trials as animals learn the task, so a single session can confound bradykinesia with task acquisition.
The pole test is strongest when pole surface and geometry, training, and scoring rules are fixed before testing, and falls and missteps are recorded separately from descent time. Time to turn and time to descend index different stages; report them separately and confirm bradykinesia with an independent motor assay such as gait analysis or the rotarod. 1
Use the rotarod for gross coordination and endurance under forced locomotion. The pole test is more specific to movement initiation and bradykinesia, especially in models of striatal dopamine depletion.
Time to turn indexes movement initiation while time to descend captures the full turning-and-climbing sequence. Reporting them separately distinguishes an initiation deficit from a descent or grip problem.
Use a textured or gauze-wrapped pole so animals climb rather than slide. A smooth surface lets animals slide down, which shortens descent time without reflecting coordinated motor control.
Quarterly editorial review of emerging Pole Test methodology. Q2 2026
Specifying pole texture and diameter improves comparability of turn and descent times between labs and reduces sliding artifacts.
High-frame-rate video and frame-by-frame scoring improve the reliability of time-to-turn and time-to-descend measurement and reduce observer burden.
Reporting time to turn and time to descend separately is increasingly expected because each captures a distinct stage of the motor sequence.
The pole test is paired with rotarod, gait analysis, and grip strength to separate bradykinesia from coordination, endurance, and strength.
