Designed and validated specifically for the mechanical stimulation and assessment of joint pain, ideal for detecting arthritis in rats and mice
Operation Specialized force sensor is worn on the thumb of the tester
Each PAM device comes standard with two force sensors, which have been specifically designed to apply force to rat and mouse joints and pedal switch
Computer software is also included for data acquisition
Excellent for quantifying: Joint Sensitivity Chronic Joint Inflammation Arthritic Pain Arthritis is associated with chronic, debilitating pain in the joints
Current metrics of arthritic pain are indirect, by scoring the level of motor activity or the animal's weight distribution
Current indirect tests, such as the weight distribution correlate well with the level of joint pain, but such a metric is a composite picture of complex pain responses, and provides little discrete information about local stimulation and locally-evoked responses
The quantification of localized joint hypersensitivity is common in the clinic, but not in animal experiments
In this sense, the new PAM device represents a step forward toward a multifactorial measurement of pain-related behavior in animal research
The PAM device is the first instrument designed specifically to apply force to the joint and automatically detect the animal's response
Instrument Configuration Pressure transducers: the PAM device comes with 2 different transducers
Each has been tested and validated in the mouse and rat knee joints: small transducer is flat and round (ideal for mouse knee joint), large transducer is flat and round (ideal for rat knee joint).
