The research investigated whether lack of inde-pendent movement of the small finger PIPJ affected the musical ability of string players. Because an anatomical variation is fixed, training and strengthening exercises will be unlikely to correct any issues of technique that arise as a result.

Professional string players were tested clinically, using standard and modified tests, for flexor digitorum superficialis function. Two additional physical tests were applied: the gap and stretch tests. The research confirms that elite violinists and viola players usually have independent FDS function.

Based on the outcome of this study, a recommendation could be made for children to be examined being offered the violin or viola as an instrument. Not everyone needs to reach a professional level. If absent FDS function is confirmed, an explanation about why certain movements are difficult to execute might be more helpful than giving the advice to practise more.
