Motor Learning and Control Application Presentation
Control Precision
Ability to make high controlled movement adjustments
Usually involved large muscles or muscle groups
Defined as a Perceptual Motor Ability
Important in injury prevention, which is a personal focus as an athlete and of future professional importance as a Physical Therapist
A simple example of this include controlling the flexion of the knee while a lot of weight/stress is on the joint
How Does This Apply?
Video taken on NYC subway of street performers. Example of an open skill
Conclusion
Control Precision
Visual Systems in Movement Control
Open/Close Skills
Coincidence Anticipation
What Are We Discussing?
Myself dancing with a Cerebral Palsy patient during my Practicum experience
Open and Closed Skills
Open Skill: performed in a environment that is unpredictable and requires the body to adapt movements in response

Closed Skill: performed in an environment that is predictable/stationary and movements can be planned in advance
In the Real World
The following video gives an example of the control precision required for powerful jumps in dance. The video is three minutes long, but thirty seconds alone provides a great example.
A Little Background
Putting It All Together...
In my experience as a dancer, control precision was a highly stressed topic when it came to jumps. If you did not control the landing of the jump, you were very likely to injure yourself because of the amount of power being put out was not balanced with control into the landing.

As well as this, as a future physical therapist, and based on my practicum experience, this is a very important concept in knee rehabilitation. When a patient has a knee injury of any kind, a main program focus for that patient is to learn how to maintain control of the joint through use of large muscle groups to prevent re-injury.
My current career goal is to become a physical therapist. I also have a strong background in dance, and hope to work with patients that are dancers in the future. In this presentation, I will not only explain the given concepts, but also relate them to my past and future experiences.
Overview
This presentation is intended to discuss and explain four concepts from Chapters 3-6, as well as apply them to real world examples and occurrences.
Common control precision exercise in a rehabilitation setting
Two systems: focal vision and ambient vision
Focal Vision: used primarily to identify objects
Ambient Vision: used to detect body orientation in your environment and is involved in action and motor control
Basis of movement control... you have to know where you're going before you move
Visual Systems in Movement Control
What is It?
After reviewing these four topics and concepts, it has become clear to me that motor learning and control will become very central to my career in the next few years when working with patients. These are relevant, everyday functions of the human body that allow us to perform at our highest level physically. They are also important skills that I use daily as a dancer, and until now had never thought of them as such.

Please provide any and all feedback. Thank You.
How do they work together?
Importance In Dance...
Focal vision allows you to identify what's around you, and ambient vision tells you where you are in relation to those objects
Part of dance involves working together with other dancers. When performing a piece, you have to visually be aware of where your fellow performers so you don't run into them. As well as this, you also must be aware of where you are in relation to the other dancers. Why? If not, you may find yourself in the wrong formation, the wrong part of the stage, ect., and thus miss key moments and cues. I find this to be of personal importance and rely on these skills to make myself a better performer and coworker to my partners
Coincidence Anticipation
Coincidence Anticipation: requires performers to produce movements that coincide in time, space, or both, with another object
Must predict what the object will do, then make an appropriate response
The most common example of this is a baseball player anticipating hitting a ball and deciding how and when to hit it
During my practicum at a physical therapy clinic, we often worked with patients through routine exercises and obstacles to better strengthen their coordination. This would be performance in a closed system. The environment was predictable, and they could plan movements. However, the ultimate goal of these exercises was to give them the coordination and open skills to adapt to an everyday unpredictable environment. Using closed skills to develop important skills is an important technique in physical therapy.
Dancers such as myself also use both open and closed skills in tandem, especially if you choose to perform in a site specific space, such as a subway or in a elevator. You can practice the piece in a closed environment, such as a dance studio, but you have to adapt and change to the environment (closed skills) once you are at your real life site. The dancers in the next slide are using their open skills because their environment (the subway) is highly unpredictable because the subway is not stationary. They more than likely, however, practiced this dance in a predictable environment, involving their closed skills.
Real World Applications
There is a special classification of dance called contact improvisation. Contact improv is performed in pairs or groups, and all the movements are made completely on the spot. The skill involved in this is that you have to anticipate what movements your partner is making while also deciding how to respond in a way that will connect your movement to them. So essentially, you are using your coincidence anticipation skills. I find this skill very important to me personally, because I use it often when performing and participating in contact improv. Because I now know that a scientific skill (coincidence anticipation) is a part of it, it validates contact improv to me as a skilled dance, rather than a dance without skill.
Contact Improvisation
Contact improvisation dance uses coincidence anticipation skills. This video gives a short example of contact improvisation. All the movements are decided on the spot, without verbal communication between partners.
To Review:
Control precision is a skill that focuses on major muscle groups that can be used for rehabilitation and injury prevention
Focal and Ambient Vision are used in daily life to identify objects and where we are in relation to them. Is also useful is athletic occurrences such as dance
Open and Closed Skills determine how we react to both predictable and unpredictable environments in daily life, and are useful for both rehabilitation and artistic purposes
Coincidence anticipation skills help us predict the movement of an object and determine how we should react. Most often useful in athletic occurrences.
