Pain and hip lateral rotator muscle strength contribute to functional status in females with patellofemoral pain
The purpose of this study was to test the hypothesis that pain and hip muscle strength explain unique portions of variance in the functional status of females with PFP. The subjects for this study were twenty-one females with PFP. Subjects had a minimum pain duration of two months. The main measures were pain during a [...]
The effect of therapeutic exercise on activation of the deep cervical flexor muscles in people with chronic neck pain.
Jull GA, Falla D, Vicenzino B, Hodges PW This study investigated the effects of low load cranio-cervical flexion (C-CF) and neck flexor strengthening exercises on spatial and temporal characteristics of DCF activation during a neck movement task and a task challenging the neck's postural stability. Forty-six chronic neck pain subjects were randomly assigned to an [...]
Effectiveness of specific neck stabilization exercises or a general neck exercise program for chronic neck disorders: a randomized controlled trial.
Griffiths C, Dziedzic K, Waterfield J, Sim J. The objective of this study was to determine whether specific neck stabilization exercises, in addition to general neck advice and exercise, provide better clinical outcome at 6 weeks than general neck advice and exercise alone. 74 participants were randomized to specific neck stabilization exercises with a general [...]
Why do some patients keep hurting their back? Evidence of ongoing back muscle dysfunction during remission from recurrent back pain
David MacDonald, G. Lorimer Moseley and Paul W. Hodges This study investigated whether the control of the short and long fibres of the deep back muscles was different in people with recurrent unilateral LBP from healthy participants. Recurrent unilateral LBP patients, who were symptom free during testing, and a group of healthy volunteers, participated. Intramuscular [...]
Reliability of a test measuring transversus abdominis muscle recruitment with a pressure biofeedback unit
Katharina von Garnier, Kirstin Köveker, Berid Rackwitz, Ulrike Kober, Sabine Wilke, Thomas Ewert and Gerold Stucki The purpose of this study was to evaluate inter-observer and test–retest reliability of the PRONE test. Forty nurses, aged between 24 and 62 years, with at least one episode of low back pain participated. During the test, movement of [...]
Training the cervical muscles with prescribed motor tasks does not change muscle activation during a functional activity
Deborah Falla, Gwendolen Jull and Paul Hodges The purpose of this study was to investigate whether either training regime changes muscle activation during a functional task which is known to be affected in people with neck pain and is not directly related to either exercise protocol. Fifty-eight female patients with chronic neck pain were randomised [...]
Effect of Stabilization Training on Multifidus Muscle Cross-sectional Area Among Young Elite Cricketers With Low Back Pain.
Hides JA, Stanton WR, McMahon S, Sims K, Richardson CA The objective of this study was to (1) investigate, using ultrasound imaging, the cross-sectional area (CSA) of the lumbar multifidus muscle at 4 vertebral levels (L2, L3, L4, L5) in elite cricketers with and without low back pain (LBP) and (2) to document the effect [...]
