Active Versus Passive Piano Intervention for Dexterity in Older Adults: A Randomized Controlled Trial

The primary finding of this study is that older adults demonstrate improvements in manual dexterity after four weeks of piano training, but do not improve significantly after just two weeks. Furthermore, it does not matter whether the participants actively play for the first part and passively listen for the second part or vice versa.

Of the three proposed mechanisms of Music Supported Therapy (MST) explained in the introduction, the findings of this study may be best explained by the emotion-motivation mechanism. Though dexterity scores were organized by whether the scores followed an active playing module, all participants experienced the same amount of music-listening and social interaction. Whether the participant was playing the music him/herself or observing, both groups were always hearing the same songs and scales for the same amount of time. The emotion-motivation mechanism states that this music-listening alone may increase cognitive processes like working memory and boost both mood and motivation. Therefore, these findings may mean that listening to piano music helps dexterity performance in older adults; but it does so if and only if the participants experience the music-listening module for a sufficient duration of time.

Along with music-listening, social interaction was consistent between active and passive groups throughout the study. This interpersonal interaction may also have had an effect on mood and motivation, as piano instructors provided high levels of encouragement and complimented the participants' progress often. Relationship quality between patient and therapist is correlated with efficacy of therapy. This concept of increased socialization contributing to dexterity improvements is also supported by a study that identified social participation as a preventative factor of perceptual speed decline in older adults.

Not finding the hypothesized effect of active versus passive condition on dexterity could be due to dexterous activities that the participants were engaged in outside of the training modules. For example, three of the 15 participants reported that they currently play piano in their free time, so it can be conjectured that those participants were engaged in active piano playing even when they were in the passive listening module. Other activities enjoyed by participants include exercise classes and painting-both of which could have been improving or maintaining their dexterity throughout the study.
