【 摘 要 】

Introduction: This paper is a literature review on the electromyographic and kinetic strategies used by the central nervous system to control voluntary movement. Such strategies have been identified from carrying out simple and complex movements, with and without direction reversal. Objective: To discuss the set of rules used to modulate the muscle activity patterns and muscle torque generated during voluntary movements involving one and two joints. Electromyographic strategies used to control simple movements involving one or two joints are dealt with first. Kinetic strategies are discussed in terms of the generation and modulation of muscle torque to carry out simple and complex movements. Linear synergy between muscle activity and muscle torque and the correlation of the muscle torque generated between chain-linked joints are then discussed. The role of interactive forces in the control of movements is also discussed. Conclusion: Physical therapy practice requires a theoretical framework based on technical-scientific knowledge to guide it. Motor control theories are powerful tools for this. Such knowledge could be used towards understanding the adaptations and modifications in motor control mechanisms that occur as a result of disorders or disease.
