Services Summarized
We provide a comprehensive description of how the patient's body moves during walking compared to age-appropriate normal walking patterns. The interpretation of the data can be used by referring physicians to determine the best possible treatment plan for the patient.
Services Include
- Split-screen videotaping
- Detailed physical assessment
- Plantar pressure analysis
- Surface electromyography
- 3-D joint motion and forces
- Temporal/spatial gait parameters
- Energy expenditure estimate
- Written report with recommendations
Services Explained
The study takes 3-4 hours and includes several components, though not all components will be necessary for every patient. Components may include:
Split-screen videotaping- Two digital video cameras (side and front views) simultaneously record the patient walking. A copy of this video accompanies the report to referring physician.
Detailed physical assessment - Our physical therapist performs a comprehensive assessment of the lower extremities, including muscle strength and control, muscle length, joint motion, spasticity, bony torsion, balance, and overall posture.
Plantar pressure analysis - The patient walks over a thin mat that electronically measures the pressures under the foot.The color-coded footprints created in the computer identify the areas of highest and lowest pressure.
Surface electromyography - Sensors (electrodes) are taped to the patient's skin over particular muscles important in walking. The computer records when muscles are active during walking. A fine wire EMG study is also available on request.
3-D joint motion and forces - Small reflective markers are taped to the patient's feet, legs, and trunk. Ten state-of-the-art, high- speed video cameras record the motion of these markers as the patient walks down a designated walkway. Before leaving, patients see the 3-D model of their own walk on the computer.
Energy expenditure estimate - Patients wear a heart rate monitor while walking for a few minutes around a track.We use the patient's heart rate and walking velocity to estimate how much energy they expend during walking.
Written report with recommendations - All information gathered in the evaluation is processed and interpreted by a highly qualified, interdisciplinary team of professionals.The referring physician is sent a video/DVD and detailed written report, including the data, a summary/interpretation, and recommendations. This information assists referring physicians in establishing a treatment plan for the patient. Physicians can expect to see results approximately three weeks following the test.
Motion Analysis Center Facilities
The Motion Analysis Center is located on Level 3 of the Mary Ives Hunting Center on the campus of Mary Free Bed Rehabilitation Hospital. The MAC uses 10 special high-speed cameras with a computerized data capture system that integrates motion, force, and electromyographic data. Cameras are wall mounted around the 1,500-square-foot testing area.
