Optimizing Outcomes in Rehabilitation: Motor Learning Principles and Beyond: Summary
areas, premotor cortex, and language areas, are all actively engaged during explicit learning. Verbal self-instruction plays a role in this process as well. Implicit learning, on the other hand, is an ongoing process operating in the background that involves subconscious control of movement. It requires preexisting motor plans and real- time strategy adjustments, which occur at a subconscious level. These processes enable individuals to perform everyday movements without consciously thinking about them.
INTRODUCTION Although traditional, or conventional, therapy is an invaluable tool for helping people manage pain and improve mobility, it has some limitations, including insufficient practice repetitions, too much focus on impairments, and training intensities that are not enough to induce neuroplastic changes in the nervous system. Fortunately, this is where motor learning comes in. Motor learning is a multifaceted process that helps individuals master new skills and refine established ones. It involves several key factors for success, including: • A healthy nervous system : Motor learning relies on having an adaptable nervous system that can respond to environmental demands and tasks. This ability to adapt, called neuroplasticity, continues throughout life and is not restricted by age. • A supportive learning environment : To maximize motor learning, it's essential to provide a safe and appropriately challenging learning environment. This helps people work toward their goals efficiently. • A well-established training method : This requires properly structured practice, intensity, goal-driven training, appropriate scaling of feedback, and ensuring that the training process is patient centered. Motor learning starts with explicit learning about a movement skill, which involves creating a conscious plan for how to execute a specific task. Explicit learning can be facilitated through various methods. • Observing and mirroring how others do it • Providing verbal and written instructions • Using mental imagery • Leveraging previously learned skills Explicit learning encompasses activities that can be consciously thought about and verbalized. It involves planning, implementing, and employing conscious thought processes. The frontal lobes, including the primary motor cortex, association
LEARNING TIP! Implicit learning is the primary factor in advanced learning, but explicit learning still has a role.
In the initial phase of motor learning, known as the cognitive phase, individuals rely on conscious thought and explicit strategies to figure out how to perform a task. During this phase, the prefrontal cortex and motor cortex are heavily engaged as the brain is trying out different strategies and adaptations to achieve the desired outcome.
| HEALTHCARE CONSIDERATION
During the cognitive phase of motor skill learning, individuals may adopt a high guard or wide base of support, leading to movements that are exaggerated and inefficient. This phase can be particularly challenging for patients, especially if they are trying to execute movements they haven’t mastered yet. It will not be beneficial to progress a patient in a certain task until they become comfortable and controlled with the movement. As individuals progress in their learning journey and adopt more effective strategies, they transition into the associative phase of motor learning. During this phase, movements become smoother and more controlled. However,
