Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Reaching for objects, walking without hitting obstacles, landing on a chair as you sit (instead of falling to the floor), these and all our physical actions depend on an ability to perceive our own bodies in space, to know where our limbs are relative to one another and relative to the rest of the world. One way that the human brain encodes this information is called proprioception, the brain relies on its own control and feedback...

In Parkinson's disease and movement disorders in general, sensitive and reliable behavioral assays are essential for testing novel potential therapeutics. Here, we describe a manageable battery of sensorimotor tests for mice that are sensitive to varying degrees of injury to the nigrostriatal system and useful for preclinical studies.

FAQs
No single measure captures every aspect of hand performance. Range of motion describes available joint movement, grip and pinch force quantify force production, while speed, coordination, and sensor-based kinematics describe how movement is organized. Combining these measures helps distinguish limited mobility, reduced strength, and impaired control, producing a more informative profile for bioengineering analysis.
These measures add dynamic information that force and range-of-motion values alone cannot provide. Movement speed indicates how quickly a task is performed, coordination reflects how effectively movements are organized, and sensor-based kinematics characterize movement patterns. Together, they help relate observed hand performance to underlying neuromuscular control and guide evaluation of assistive technologies.
Standardized functional tasks show how the hand performs activities under consistent conditions, making results easier to compare across assessments. Instrument-based measures add quantitative detail about motion, force, and coordination during or alongside those tasks. This combination connects practical performance with measurable physical variables, strengthening outcome evaluation in rehabilitation and device development.
Assessment data identify which aspects of performance require support, such as movement range, grip force, pinch force, speed, or coordination. Bioengineers can use these measurements to evaluate whether a prosthetic hand or orthosis addresses the relevant limitation. Repeated assessment also provides evidence for validating device performance and refining designs around measured user needs.
A practical workflow begins by selecting standardized functional tasks and complementary measures suited to the performance question. The evaluator then records relevant variables, such as range of motion, grip and pinch force, movement speed, coordination, or sensor-based kinematics. Comparing these results across time supports tracking of recovery, disease progression, or treatment response.
Researchers apply it when they need objective evidence about hand performance or change over time. Uses described in bioengineering include evaluating rehabilitation technologies, validating prosthetic hands and orthoses, supporting human-machine interfaces, and personalizing assistive devices. The same measurements can also help relate device function or treatment effects to meaningful changes in everyday task performance.
