Overview
This lecture discusses the practical application of the Four Element Movement System (motion, force, energy, motor control) in patient management, illustrated through a case study of a stroke patient.
Four Element Movement System Review
- The four elements are motion, force, energy, and motor control.
- The system uses a five-step process: observe movement, hypothesize impairments, perform objective testing, evaluate contextual factors, and provide targeted interventions.
Case Study: Mike
- Mike is a 38-year-old male with right hemiparesis and expressive aphasia after a left hemisphere stroke.
- Observations during sit-to-stand revealed poor control, reduced trunk flexion, asymmetry, slow speed, and lack of movement smoothness.
- Hypothesized impairments included deficits in motor control, force generation, and joint motion.
Objective Testing and Findings
- Passive range of motion testing found hip motion limitations and decreased lumbar spine lordosis.
- Muscle testing showed weakness in hip and knee extensors and the right lower extremity.
- Fugl-Meyer assessment indicated impaired motor control; task completion was slow and abnormal.
- Mike compensated with asymmetrical weight-bearing and needed to use his arms for sit-to-stand.
Intervention Strategies
- Motor control interventions included task practice, varied strategies, mental imagery, and using music as a cue.
- Motion interventions involved joint mobilizations and hamstring stretching.
- Force interventions focused on closed-chain strengthening and power training.
- External visual cues (e.g., an object to reach for) proved effective for trunk flexion.
- Functional training also included practicing walking for further muscle strengthening.
Functional and Contextual Considerations
- Mike faced barriers from aphasia, right upper extremity impairment, limited insurance, and environmental challenges at home.
- Cultural and social factors influenced his motivation and participation.
Correct Sequence of Four Element Movement System Application
- Observe movement and function.
- Hypothesize impairments in the four elements.
- Perform objective testing related to the four elements.
- Evaluate problems and prognosis, considering contextual factors.
- Provide interventions focusing on motion, force, energy, and motor control.
Key Terms & Definitions
- Four Element Movement System — A framework for analyzing and intervening in movement based on motion, force, energy, and motor control.
- Motor Control — The ability to regulate movement timing and coordination.
- Objective Testing — Measurements and assessments used to confirm suspected impairments.
- External Visual Cue — A physical object placed to guide or prompt movement.
Action Items / Next Steps
- Review the steps of the Four Element Movement System and practice applying them to case examples.
- Consider contextual and environmental factors when planning interventions for patients.
- Practice using external visual cues and varied practice strategies in motor training.
