Role of Diffusion Tensor Tractography in Diagnosis of Limb-Kinetic Apraxia in Stroke Patients: A Mini-Narrative Review
Limb-kinetic apraxia (LKA) is an execution disorder of movements caused by an injury to the secondary motor area (the supplementary motor area and premotor cortex) with preservation of an intact corticospinal tract (CST). A precise diagnosis of LKA is often limited because it is made based on the cl...

description | Limb-kinetic apraxia (LKA) is an execution disorder of movements caused by an injury to the secondary motor area (the supplementary motor area and premotor cortex) with preservation of an intact corticospinal tract (CST). A precise diagnosis of LKA is often limited because it is made based on the clinical observation of movement characteristics with confirmation of the CST state, and no specific clinical assessment tools for LKA have been developed. Diffusion tensor tractography (DTT) enables a three-dimensional estimation of the neural tracts related to LKA, such as the CST and corticofugal tract from the secondary motor area. This article reviewed 5 DTT-based studies on LKA-related neural tracts in stroke patients. These studies suggest that DTT could be a useful diagnostic tool for LKA along with previous diagnostic tools, such as brain magnetic resonance imaging and transcranial magnetic stimulation. In particular, DTT for the affected corticofugal tract can provide useful evidence for diagnosing LKA when clinicians cannot observe the movement characteristics because of severe weakness after a severe injury to the affected CST. Furthermore, a reviewed study suggested that LKA might be related to the unaffected neural tracts for motor function when the affected neural tracts were severely injured. This review summarizes the role of DTT in the diagnosis of LKA in stroke patients. |
