Study, type of publication Design Participants Experimental intervention(s) Control intervention(s) Outcome measures Main results
Doyle 1984 [24], PhD thesis RCT 72 Short hands-on contact with thought: free neck muscles before playing Short hands-on contact with thought: tighten neck muscles before playing Head-neck relationship 98.6% of subjects showed changes in the head-neck relationship when taking up their instrument to play.
Violin players (Defined as the angle between a line going through the sternal notch and the first dorsal vertebra and a vertical line going through the middle of the chair and measured on photographs) Release in tension in the neck muscles was closely associated with postural changes towards the grid vertical in 71.4% of subjects (p <0.001). When tightening the neck muscles 94.6% moved in a forward direction (p <0.001).

Dennis 1987 [25], Ed.D. dissertation RCT 13 AT None Music performance (posture, movement, breath control, overall performance) judged by 6 expert observers from video-tapes on a 7-point scale Control group performed better in maximal voluntary ventilation (t-test, p =0.052); no other significant differences between groups occurred.

Physical exercise Assessment by 3 expert judges from video-tape in random order on 10-point scales adapted from a standard set of music performance evaluation criteria (overall quality, perceived instrumental competence, musicality/musical understanding and communication) Significant improvements in music performance occurred in the alpha/theta NF group (p <0.01 for 3 out of 4 criteria; mean improvement rate 12%), but no post-training performance changes in any other group.

- RCT Female violinists and violists, age 18–34 years 20 sessions, 30 min, twice a week, over 10 weeks, one-to-one - Questionnaires (quantitative, questions from author and previous studies, von Korff scale for pain, 10-point Likert scales) Convergence of quantitative and qualitative data showed also improvement in pain.

Barlow 1956 [31], peer-reviewed CT 74 AT (“conditioning”) Verbal instructions, manual adjustment, exercises Postural faults (according to author’s scoring system) In the AT group the number of faults decreased from 9 to 4 in women and from 11 to 5 in men. In the control group the number of faults increased from 7.5 to 7.9 in women and from 10.6 to 11.7 in men.c
