addressed this issue by using an animation file to count the number of grip-and-release cycles in 15 s (15-s test). This judgment is particularly affected by paradoxical wrist motion (trick motion), in which patients with myelopathy compensate for the impaired finger motion with exaggerated wrist motion. This test is subject to inter-observer variability, depending on whether the observer judges the fingers to be flexed or extended. However, it is not widely used, mainly because its reliability has not been validated. The grip-and-release test is simple and easy to use in clinical settings. proposed the original grip-and-release test (10-s test), which evaluates rapid finger motion by counting the maximum number of grips and releases in 10 s. Several performance tests have been developed for objectively assessing the severity of myelopathy hand. However, because these scales classify a wide range of clinical severity using only a few arbitrary units, the measurements are not strongly quantitative and their sensitivity to change is likely to be poor.
These scales are widely used to monitor the disease condition and to compare clinical outcomes after decompression surgery. The severity of myelopathy hand can be assessed using functional scales such as the Cooper Myelopathy Scale, European Myelopathy Score, and Japanese Orthopaedic Association (JOA) score.
This hand dysfunction, also called myelopathy hand, is characterised by exaggerated deep tendon reflexes, deficient adduction and/or extension of the ulnar two fingers (the finger escape sign), and difficulty in rapid grip-and-release movements of the fingers. Hand clumsiness is one of the most common complaints of patients with compressive cervical myelopathy due to degenerative spondylosis, disc herniation, or ossification of the longitudinal ligament.
