| Choking under pressure | Describes acute performance failure when individual perceives a subjectively unmanageable situation accompanied by fear of failure, anxiety and increased arousal leading to reduced motor control and worse performance outcome. |
| Dynamic stereotype | Used when motor incoordination persists for more than 4 weeks. More modifiable and fluctuating than musicians dystonia. |
