Laboratory for the evaluation of neuromuscular functions of the trunk


  • Research interests:
    • Development of objective measures (validity and fidelity studies) to quantify neuromuscular impairments associated with chronic low back pain: (1) back muscle weakness and fatigability, (2) abdominal and deep back muscle atrophy and control, (3) lumbar proprioception, (4) anticipatory postural adjustments, and (5) trunk muscle reflex responses, (6) trunk postural balance, (7) inter-segmental and muscular coordination, and (8) lumbar stiffness.
    • Evaluation of interventions to reduce lumbar instability. The first is an active intervention, i.e., a lumbar stabilization exercise program. The second is passive, involving the use of a lumbar belt. The interventions are evaluated with primary (pain intensity, disability) and secondary (neuromuscular deficits) outcome measures while taking into account variables that may potentially modify these effects (psychological variables associated with pain, treatment adherence, etc.).
    • Quantitative methodologies including these measures:
      • Objective measures: surface electromyography, dynamometry, 3D kinematics, ultrasonograph
      • Subjective measures: questionnaires related to pain, perceived disabilities, psychological variables associated with pain (kinesiophobia, dramatization, etc.) or adherence to treatment.
