Proprioceptive accuracy is not associated with self-reported body awareness, body competence, and affect

Purpose: Proprioception plays an essential role in motor control and in psychological functioning: it is the basis of body schema and the feeling of body ownership. There are individual differences in the processing accuracy of proprioceptive stimuli. Although proprioceptive acuity plays an important role in physical competence, there are contradictory findings concerning the role it plays in healthy psychological functioning. This study aims to shed more light on this association. Material and methods: Sixty-eight young adults participated in this study. We estimated proprioceptive acuity by the reposition accuracy of elbow joint positions. We tested both dominant and non-dominant hands with two different versions of Joint Position Reproduction Test. Perceived physical competence, body awareness, and affectivity were assessed using questionnaires (Physical Competence scale of Body Consciousness Questionnaire, Somatic Absorption Scale, and Positive and Negative Affectivity Schedule, respectively). Results: No significant association between proprioceptive acuity and body awareness, perceived body competence, and positive and negative affect was found. Conclusion: Proprioceptive acuity, measured in the elbow joint, does not play a substantial role in body awareness, perceived body competence, and affect.
