THEORY AND PHENOMENON: Differences in the psychoneuroendocrinological profile of individual organisms within one and the same species partly explain the large range of health status variability. Relative little is known about the relevance of this phenomenon for locomotor tract disorders, a quest of interest for physical therapy. PURPOSE AND TESTABLE HYPOTHESIS: In this perspective a line of basic, animal research was started in order to explore the conceptual hypothesis that the interindividual variability of psychoneuroendocrinological profiles is significant for [a] the course, [b] the recovery, and [c] the therapeutic susceptibility of locomotor tract pathologies. EVIDENCE: Numerous experiments were carried out, using distinct tests of locomotor function to monitor the "clinical" course of recovery of rats, in several well known experimental models (e.g. peripheral nerve lesion, streptozotocin induced diabetes mellitus, contusive spinal cord injury, and adjuvant-induced arthritis). Rats were behaviorally screened (explorative locomotor activity by open field analysis) and their biological profile (Hypothalamus-Hypophyses-Adrenal axis, Sympatho-Adrenergic-axis) was determined. At later stages in the project several therapeutic intervention strategies and distinctive ecological chronic stress regimen were introduced. The results of these experiments clearly demonstrate the significance of biobehavioral determinants for the course of functional recovery of rats following induction of an experimental locomotor tract pathology. Especially when chronic stress was introduced biological correlates with functional recovery became more pronounced. IMPORTANCE: The relationships between on the one hand individual psychological, partly inherited traits and neuroendocrinological characteristics, and, on the other hand, the rate and quality of recovery after induction, but even more so the contrasts in therapeutic susceptibility between individual rats, underscores the importance of these interindividual differences for the consequences of locomotor tract injury and recovery. Based on these animal experiences and with help of the literature a theoretical framework was constructed for further basic and clinical research aiming at improvement of therapies and rehabilitation from locomotor tract disorders. In the near future, we aim to investigate the mechanisms underlying these phenomena, as well as the importance of interferences of aforementioned characteristics on the outcome of for instance exercise training in these experimental models., Van Meeteren NLU,(1),(2) Helders PJM,(2) Papp M,(3) Wiegant VM,(1) Gispen WH(1).
