Functional Movement Screening: Identifying and Correcting Movement Patterns for Optimal Performance

In today's world, where individuals engage in diverse physical activities ranging from competitive sports to everyday tasks, understanding and optimizing movement patterns is crucial. The Functional Movement Screen (FMS) has emerged as a valuable tool for assessing movement quality, identifying limitations, and guiding corrective strategies. This comprehensive guide explores the FMS, its underlying principles, the screening process, and effective corrective exercises to improve movement patterns and reduce the risk of injury.

What is Functional Movement Screening (FMS)?

The Functional Movement Screen (FMS) is a standardized assessment tool used to evaluate fundamental movement patterns. Developed by Gray Cook and Lee Burton, the FMS consists of seven distinct movement patterns designed to identify limitations and asymmetries in mobility and stability. These patterns reflect fundamental movement skills necessary for daily activities and athletic performance. The FMS aims to identify dysfunctional movement patterns that may predispose individuals to injury or limit performance.

The Seven Functional Movement Screen Tests:

• Deep Squat: Assesses bilateral, symmetrical, and functional mobility of the hips, knees, and ankles.
• Hurdle Step: Challenges proper stepping mechanics and assesses hip and core stability during single-leg stance.
• In-Line Lunge: Evaluates asymmetrical lower extremity function, balance, and core stability.
• Shoulder Mobility: Assesses shoulder range of motion and symmetry in internal and external rotation, adduction, and reaching.
• Active Straight-Leg Raise: Evaluates hamstring flexibility, hip mobility, and core stability.
• Trunk Stability Push-Up: Assesses core stability and the ability to maintain a neutral spine during upper body movement.
• Rotary Stability: Evaluates core stability and coordination during asymmetrical upper and lower extremity movement.

Why is Functional Movement Screening Important?

The FMS offers numerous benefits for individuals across various populations, including athletes, fitness enthusiasts, and individuals seeking to improve their overall movement quality. Here are some key reasons why the FMS is important:

• Injury Risk Assessment: The FMS can help identify individuals who are at a higher risk of injury due to dysfunctional movement patterns. By identifying limitations and asymmetries, targeted interventions can be implemented to address these issues and reduce the likelihood of injury. For example, a study by Kiesel et al. (2007) demonstrated a significant association between FMS scores and injury risk in American football players.
• Performance Enhancement: Addressing movement limitations identified through the FMS can improve movement efficiency and optimize athletic performance. By correcting dysfunctional patterns, individuals can move more effectively and generate greater power and speed. Imagine a runner in Kenya improving their stride by addressing a hip mobility issue identified through FMS.
• Rehabilitation Guidance: The FMS can be used as a tool to guide rehabilitation programs following injury. By identifying specific movement impairments, therapists can develop targeted interventions to restore optimal function and prevent re-injury. A physical therapist in Brazil might use FMS to track the progress of a patient recovering from an ACL reconstruction.
• Objective Measurement: The FMS provides an objective and standardized assessment of movement quality. This allows for consistent tracking of progress over time and facilitates communication between healthcare professionals and individuals.
• Early Intervention: The FMS allows for the identification of movement dysfunction before symptoms develop. This enables early intervention to address issues before they lead to pain or injury.

The FMS Screening Process: A Step-by-Step Guide

The FMS screening process involves a series of standardized tests, each designed to assess a specific movement pattern. The process typically involves the following steps:

1. Introduction and Explanation: The individual is provided with a clear explanation of the FMS and its purpose. They are informed about the movement patterns they will be performing and the scoring system.
2. Demonstration: The FMS administrator demonstrates each movement pattern to ensure the individual understands the proper technique.
3. Performance: The individual performs each movement pattern while the administrator observes and assesses their form.
4. Scoring: Each movement pattern is scored on a scale of 0 to 3, with 3 representing perfect execution and 0 indicating inability to perform the movement.
5. Interpretation: The FMS scores are analyzed to identify areas of limitation and asymmetry.

FMS Scoring System:

• 3: Performs the movement pattern perfectly without any compensations.
• 2: Performs the movement pattern with some compensations.
• 1: Performs the movement pattern with significant compensations.
• 0: Unable to perform the movement pattern or experiences pain during the movement.

Common Movement Dysfunctions Identified by FMS

The FMS can reveal various movement dysfunctions that may contribute to pain, injury, or performance limitations. Some common dysfunctions identified by the FMS include:

• Limited Ankle Mobility: Restricted ankle dorsiflexion can impact squatting mechanics and contribute to knee pain.
• Poor Hip Mobility: Limited hip internal rotation or flexion can affect gait patterns and increase the risk of hip impingement.
• Core Instability: Weakness or dysfunction of the core muscles can compromise spinal stability and increase the risk of back pain.
• Shoulder Impingement: Limited shoulder mobility or muscle imbalances can lead to shoulder impingement and pain.
• Asymmetrical Movement Patterns: Differences in movement quality between the left and right sides of the body can indicate underlying imbalances.

Corrective Exercises: Addressing Movement Limitations

Once movement limitations have been identified through the FMS, targeted corrective exercises can be implemented to improve movement patterns and address underlying dysfunctions. Corrective exercises typically focus on improving mobility, stability, and motor control. Here are some examples of corrective exercises for common FMS findings:

Corrective Exercises for Limited Ankle Mobility:

• Ankle Mobilization with Band: Place a resistance band around the ankle joint and perform dorsiflexion movements to improve ankle mobility.
• Calf Stretches: Perform static or dynamic calf stretches to improve flexibility of the calf muscles.

Corrective Exercises for Poor Hip Mobility:

• Hip Flexor Stretch: Perform a kneeling hip flexor stretch to improve hip extension and flexibility.
• Piriformis Stretch: Perform a seated or supine piriformis stretch to improve external rotation of the hip.

Corrective Exercises for Core Instability:

• Plank: Perform a plank exercise to strengthen the core muscles and improve spinal stability.
• Bird Dog: Perform a bird dog exercise to improve core stability and coordination during asymmetrical movement.

Corrective Exercises for Shoulder Impingement:

• Thoracic Spine Mobility Exercises: Use a foam roller or perform thoracic extensions to improve mobility of the upper back.
• Scapular Retractions: Perform scapular retractions to strengthen the muscles that stabilize the shoulder blade.

Integrating FMS into Training and Rehabilitation Programs

The FMS can be effectively integrated into training and rehabilitation programs to optimize movement quality and reduce the risk of injury. Here are some strategies for integrating the FMS:

• Pre-Participation Screening: Conduct FMS screenings on athletes or individuals before they begin a training program to identify potential movement limitations.
• Program Design: Use FMS results to inform program design and select exercises that address identified movement limitations.
• Progress Monitoring: Re-assess FMS scores periodically to track progress and adjust training or rehabilitation programs accordingly.
• Warm-up and Cool-down: Incorporate corrective exercises into warm-up and cool-down routines to address specific movement limitations.

Case Studies: Real-World Applications of FMS

The FMS has been successfully implemented in various settings, including sports teams, fitness facilities, and rehabilitation clinics. Here are a few examples of how the FMS has been used in real-world applications:

• Professional Sports: Many professional sports teams use the FMS to screen athletes for potential injury risks and to develop individualized training programs. For example, a basketball team in Europe might use FMS to identify and correct movement imbalances in their players, reducing the incidence of ankle sprains.
• Military Training: The military utilizes the FMS to assess the physical readiness of recruits and to develop training programs that improve movement efficiency and reduce injury rates.
• Workplace Wellness Programs: Companies are increasingly using the FMS as part of their workplace wellness programs to identify ergonomic risks and to promote healthy movement habits among employees. An office in Japan might implement FMS to identify employees with poor posture and provide them with corrective exercises.

Limitations of FMS

While the FMS is a valuable tool, it's important to acknowledge its limitations. The FMS provides a snapshot of movement patterns at a specific point in time and may not capture all aspects of functional movement. Factors such as fatigue, stress, and psychological state can influence FMS scores. Additionally, the FMS does not directly assess strength or power, which are also important components of athletic performance. Also, the scoring is subjective and can depend on the rater's experience and training. Therefore, the FMS should be used in conjunction with other assessment tools to provide a comprehensive evaluation of movement quality.
