+====== Case MVC ======
+This is a clinical case report presented as an example of a gait analysis.
+[[https://www.has-motion.com/download/examples/CaseMVC.zip|Download the .zip file]]
+=== History: ===
+year old female
+diagnosed with polymyositis
+also 5 years post motor vehicle crash resulting in right femur fracture and neurological damage at L1/L2 on left
+//Polymyositis is an inflammatory muscle disease that causes varying degrees of decreased muscle power. The disease has a gradual onset and generally begins in the second decade of life. Polymyositis rarely affects persons under the age of 18. The most common symptom is muscle weakness, usually affecting those muscles that are closest to the trunk of the body (proximal). Eventually, patients have difficulty rising from a sitting position, climbing stairs, lifting objects, or reaching overhead. In some cases, distal muscles (those not close to the trunk of the body) may also be affected later in the course of the disease. Trouble with swallowing (dysphagia) may occur. Occasionally, the muscles ache and are tender to touch. Patients may also feel fatigue and discomfort and have weight loss or a low-grade fever.//
+=== Impairments: ===
+Right lower extremity 2 cm shorter than left
+Decreased sensation below L1/L2 on left
+Muscle weakness (score out of 5)

+=== Functional Limitations: ===
+Difficulty with ambulation on all surfaces, uses cane outside the home
+=== Gait Evaluation: ===
+Reason for referral: Rehabilitation treatment recommendations, especially with respect to bracing
+Test conditions: Barefoot walking without assistive or orthotic devices
+=== Highlights of results for Case MVC ===
+Impairments creating functional problems
+  * Right leg length discrepancy
+  * Bilateral ankle dorsiflexor weakness (much worse on left)
+  * Left knee extensor weakness
+\\
+Right leg 2 cm shorter than left AND left foot drop (exaggerates difference)
+Primary gait findings:
+Leg length discrepancy = asymmetrical vertical pelvic motion
+Left foot drop = increased ankle plantar flexion in swing phase
+flat foot at initial contact
+Secondary Compensations:
+increased left knee flexion, hip flexion, and hip abduction in left swing phase
+Left knee extensor weakness
+Primary gait findings:
+Knee hyperextended with flexor moment
+Secondary Compensations:
+increased left hip extensor moment and power
+Some increased ankle plantar flexor eccentric work (at end range)
+=== Treatment recommendations: ===
+Flexible ankle foot orthosis on left
+Flexible to allow body to progress over left foot in late stance phase and substitute for eccentric function of ankle plantar flexors
+Consider casting orthosis in 5 deg of plantar flexion to enhance eccentric plantar flexion function
+Right shoe lift to correct leg length discrepancy
+Reassess need for orthosis on right after above completed
