Current ResearchClassification of condition
Gain better understanding of range of motion and muscle strength
•Congenital •Very rare•Especially on just one hand•Both hands would be genetic
•Ectrodactyly type •Ectro- absence of •Dactyly- arrangement of digits
•Missing 4 central metacarpals and the 5th proximal phalanx

Current ResearchViolin Bowing Techniques
Current configuration inhibits movement
Karen would like to see improvement with certain bow strokes:
•Depend on balance point•Spiccato-bow bounces on strings
•Certain Techniques require powerful strokes•Martele-power/hammer stroke

ConclusionFiona needs a new bow attachment to replace her current model
The real challenge :
Although this project may seem easy at first…
Difficult to communicate with Fiona because she is shy…
The product must be to her express liking…
