Alterations in volitional control have been found for various mental disorders. However, it remains unclear to which degree such alterations vary by type of psychopathology and constitute preceding vulnerabilities or correlates of mental disorders. DSM-IV mental disorders were assessed among adolescents and young adults from the community at baseline (age 14-24) and in up to 3 follow-up assessments over 10 years (n = 2515) using a standardized diagnostic interview (DIA-X/M-CIDI). Self-reported volitional control was assessed at second follow-up (T2) when subjects were aged 17-28 using the German version of the Short Form of the Volitional Components Inventory. Linear regressions adjusted for sex, age and lifetime disorders revealed that anxiety and affective disorders were associated with widespread alterations in self-reported volitional control (lower self regulation, higher self inhibition and volitional inhibition), while substance use disorders were specifically associated with higher volitional inhibition. Logistic regressions adjusted for sex, age and prior lifetime psychopathology revealed that lower self-reported volitional control at T2 predicted incident panic, social phobia and substance use at T3 (follow-up interval M = 4.8 years). Findings point toward at least partly disorder-specific alterations in volitional control in mental disorders, which might be antecedent vulnerability factors and thus useful to guide early recognition and prevention.

Many individuals with incomplete spinal cord injury (SCI) exhibit reduced volitional control of trunk muscles, such as impaired voluntary contractions of the erector spinae (ES), due to damage to the neural pathways regulating sensorimotor function. Studies using conventional bipolar electromyography (EMG) showed alterations in the overall, or global, activation of the trunk muscles in people with SCI. However, how activation varied across specific regions within the ES, referred to as regional activation, remains unknown.

Background: There is growing interest in use of transcutaneous spinal stimulation (TSS) for people with neurologic conditions both to augment volitional control (by facilitating motoneuron excitability), and to decrease spasticity (by activating inhibitory networks). Various electrode montages are used during TSS, with little understanding of how electrode position influences spinal circuit activation. We sought to identify the thoracolumbar electrode montage associated with the most robust activation of spinal circuits by comparing posterior root-muscle reflexes (PRM reflexes) elicited by 6 montages.

Introduction: Detrusor contractions can be classified as either volitional or involuntary. The latter are a hallmark of urge urinary incontinence. Understanding differences in neuroactivation associated with both types of contractions can help elucidate pathophysiology and therapeutic targets.
