Pattern 4: Distal Arm/ProximalLeg Weakness
{"Image DocumentName": "Pattern 4: Distal Arm/ProximalLeg Weakness", "Image ImageDescription": "This pattern is associated with distal arm weakness involving the distal forearm muscles (wrist and finger flexors) and proximal leg weakness involving the knee extensors (quadriceps). The facial muscles are usually spared. Involvement of other muscles is extremely variable. The weakness is often asymmetrical between the two sides, which is uncommon in most myopathies. This pattern is essentially pathognomonic for inclusion body myositis (IBM). This pattern may also represent an uncommon presentation of myotonic dystropy; however, unlike IBM, muscle weakness is usually symmetrical.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
