Emotionally affective imaginations influence the Adaptive Force (AF) in healthy participants as was recently shown. The AF describes the neuromuscular holding capacity, suggested to be especially vulnerable for interfering inputs. The present study investigated the influence of neutral, pleasant, and unpleasant food imaginations on the manually assessed AF objectified by a handheld device of elbow and hip flexors in 12 healthy participants with improved design. Muscle lengthening started on a

Thus, healthy participants show an impaired holding function due to negative imaginations. Assuming this leads to joint destabilization, musculoskeletal complaints might result. It could support understanding the causal chain of linked pain and mental issues. A case example (current stress vs. positive imaginations) will be presented, underpinning the hypothesis this approach might support psychomotor diagnostics and therapeutics.
