摘要

探討技巧性動作的理論逐漸強調執行者與表現情境的互動關係。職能治療領域裡，也逐漸開始研究環境因子如何影響動作表現。在許多不同的環境因子中，活動之目標性和與活動相關物質特性被認爲是組織和決定動作的基本條件。本篇報告註解具代表性的相關文獻，基中涵蓋技巧性動作之機轉、不同情境下之動作特徵、以及中風病人之復健。本文強調四大議題：(1)提供技巧性動作產生過程之理論架構；(2)解析活動之目標性對視覺引導下之手部動作的效應；(3)註解特質特性對上肢動作之影響；(4)探討此類知識與研究體系對中風復健的啓示。文末提出上肢伸展與抓握型態研究未來之發展方向。

There are growing theories of motor control regarding mechanisms of skilled movements describing the interaction between performer and the performance context. In occupational therapy, recent attention has been geared toward studying how environmental (contextual) factors may influence movement performance. Among various environmental factors, task goal and object-related factors (e.g., perceived object characteristics and position) have been thought of as essential factors in organizing or determining movement. The present paper attempted to annotate relevant and representative research on mechanisms responsible for skilled movements, characteristics of movements involving a variety of contexts, and rehabilitation of post-stroke patients. Specifically, four issues were addressed in this annotated bibliograpy: (1) a theoretical framework for the processes of skilled movements; (2) the effects of task goal on visually guided hand movements; (3) the influences of object-related factors; and (4) implications of this body of research for stroke rehabilitation. Recommendations for future research on establishing normative data regarding reaching and grasping patterns were provided.
