The index finger would curl down and so would be out of position for depressing the keys. The official finger spring supplied was unsatisfactory as it covered the pad of his finger needed to feel the piano key.
Several versions of a splint were developed, each one refining the dexterity; allowing the client to feel the piano key. The support was made using leather, Tupperware and velcro – the velcro allowing him to adjust the degree of tightness required.
The client was able to play the piano again, which gave him a lot of enjoyment.
