Coordination
Common Coordination Impairments
| Term | Definition |
|---|---|
| Asthenia | Generalized muscle weakness |
| Asynergia | Loss of ability to associate muscles together for complex movements |
| Delayed Reaction time | Increased time required to initiate voluntary movement |
| Dysarthria | Disorder of the motor component of speech articulation |
| Dysdiadochokinesia | Impaired ability to perform rapid alternating movement |
| Dysmetria | Inability to judge the distance or range of a movement |
| Dyssynergia | Movement performed in a sequence of component parts rather than as a single smooth activity |
| Gait Disorders | Ataxic pattern; broad base of support; postural instability; high guard position of UE's |
| Hypotonia | Decrease in muscle tone |
| Hypermetria | Overestimation of distance or range needed to accomplish a movement |
| Hypometria | Underestimation of distance or range needed to accomplish a movement |
| Nystagmus | Rhythmic, quick, oscillatory, back-and-forth movement of the eyes |
| Rebound Phenomenon | Inability to halt forceful movements after resistive stimulus is removed |
| Tremor | Involuntary oscillatory movement resulting from alternate contractions of opposing muscle groups |
| Intention tremor | Oscillatory movement during voluntary motion; increases as limb nears target; diminished or absent at rest |
| Postural tremor | Exaggerated oscillatory movement of the body in standing posture or of a limb held against gravity |
| Titubation | Rhythmic oscillation s to the head, axial involvement of the trunk |
| Akinesia | Inability to initiate movement |
| Athetosis | Slow, involuntary, writhing, twisting, "worm like" movements |
| Bradykinesia | Decreased amplitude and velocity of movement |
| Chorea | involuntary, rapid, irregular, jerky movements involving multiple joints |
| Choreoathetosis | Movement disorder with features of both chorea and athetosis |
| Dystonia | Sustained involuntary contractions of the agonist and antagonist muscles |
| Hemiballismus | Large-amplitude, sudden, violent, flailing motions of the arm and leg of one side of the body |
| Hyperkinesis | Abnormally increased muscle activity or movement |
| Hypokinesis | Decreased motor response especially to a specific stimulus |
| Rigidity | Increased muscle tone causing greater resistance to passive movement |
| Lead-Pipe Rigidity | Uniform constant resistance as limb is moved |
| Cogwheel Rigidity | Series of brief relaxations or catches as limb is moved |
| Resting Tremor | Involuntary, rhythmic oscillatory movement observed at rest |
