Temporal Neuromuscular Alterations Of The Quadriceps After Unilateral Anterior Cruciate Ligament Reconstruction, Conrad M. Gabler
Temporal Neuromuscular Alterations Of The Quadriceps After Unilateral Anterior Cruciate Ligament Reconstruction, Conrad M. Gabler
Theses and Dissertations--Rehabilitation Sciences
Objective: The primary aim of this research was to examine the temporal pattern of neuromuscular quadriceps deficits in both the involved and uninvolved limbs of patients assigned to the control group after anterior cruciate ligament reconstruction (ACLr), by assessing quadriceps strength, voluntary activation, and corticomotor excitability prior to surgery (baseline), three months after ACLr, and six months after ACLr. A secondary aim of this research was to determine whether quadriceps strength, voluntary activation, and/or corticomotor excitability assessed in patients prior to ACLr and/or at three months after surgery, is predictive of lower extremity postural control and/or self-reported function at six …
Muscular And Neural Contributions To Postactivation Potentiation, Brian Joseph Wallace
Muscular And Neural Contributions To Postactivation Potentiation, Brian Joseph Wallace
Theses and Dissertations--Kinesiology and Health Promotion
Muscle performance is partially a consequence of its recent contractile history. Postactivation potentiation (PAP) can occur after muscle contractions and leads to enhanced neuromuscular performance. The purpose of this dissertation was to explain the relationship between muscle factors (twitch potentiation, TP) and neural factors (reflex potentiation, RP) contributing to overall PAP following a non-fatiguing volitional muscle contraction. The tibial nerves of fifteen resistance trained volunteers (eleven men, four women) were stimulated intermittently at supramaximal (Mmax) and submaximal (Hmax) intensities for 20 minutes on separate days under three conditions: rest (Control); after a after a 10 second maximum voluntary isometric contraction …
