Locomotion and Dynamic Posture: Neuro-evolutionary Basis of Bipedal Gait

Guillaud E, et al. Locomotion and dynamic posture: neuro-evolutionary basis of bipedal gait. Neurophysiologie Clinique/Clinical Neurophysiology (2020),  https://doi.org/10.1016/j.neucli.2020.10.012

This review article explains the networks that the trunk in vertebrates with limbs, and also how the central nervous system acts dynamically on the musculoskeletal system.

 

Key Points

  • Dynamic control of gait is supported by:
    • Locomotor activity that is produced by specialized rhythmogenic spinal circuits called central pattern generators (CPGs), and which cyclically drive axial and leg muscle activity (p.8)
    • Posture control systems which involve long...

Footwear Alters Lower Extremity Coordination Variability

Romer, Braden H., Wendi Weimar, and John Fox. "Footwear Alters Lower Extremity Coordination Variability." Perceptual and Motor Skills 126, no. 5 (2019), 764-778. doi:10.1177/0031512519863183.

This was a small study gauging the influence of footwear on motor coordination, and thus results are not transferable across populations. However, the findings are interesting from a clinical perspective, as this adds to information re: training for functional tasks with appropriate footwear.

 

Key Points

  • Footwear, footwear components, and tactile feedback are capable of producing significant changes in gait mechanics and lower extremity muscle activity.
  • The amplitude and...

Clinical Pilates in Practice: Joint Impairment & Gait in Juvenile Idiopathic Arthritis (July 2020)

Researchers used a musculoskeletal model to predict joint contact forces and investigate the variations of joint contact forces due to joint impairment in 18 juvenile idiopathic arthritis patients.

 

Erica Montefiori et al. Linking Joint Impairment and Gait Biomechanics in Patients with Juvenile Idiopathic Arthritis. Annals of Biomedical Engineering 2019; 47(11): 2155-2167

 

KEY POINTS: JOINT IMPAIRMENT & GAIT BIOMECHANICS IN JUVENILE IDIOPATHIC ARTHRITIS

  • Juvenile idiopathic arthritis (JIA) is the commonest rheumatic condition in childhood, although the etiology remains unknown.
  • JIA encompasses several subgroups but most generally presents as peripheral arthritis.
    • Clinical presentation includes fever, joint swelling and pain, hepatomegaly, lymphadenopathy, cardiac involvement, splenomegaly, and skin rashes.
  • Medical imaging of JIA:
    • Ultrasound is used to assess joint synovial and tendon inflammation.
    • MRI helps with early...

Consolidation of Use-Dependent Motor Memories Induced By Passive Movement Training

G. Tays et al. Consolidation of use-dependent motor memories induced by passive movement training. Neuroscience Letters 732 (2020) 135080.

This study examined the lasting effect of passive training on visuomotor adaptation within a 24-hour timeline.

 

Key Points

  • Adapting to a sensorimotor environment requires complex and dynamic systems that can adjust to the environment within minutes, resulting in long-term performance changes.
  • Adaptation is driven by two primary learning mechanisms:
    • Error-based, model-based, or algorithmic learning; and
    • Use-dependent, model-free, or instant-reliant training.
  • Use-dependent learning occurs both during active...

Clinical Pilates in Practice: Biomechanics of Pregnancy (February 2020)

This is a systematic review of 50 papers looking at how biomechanical changes during pregnancy will affect quality of life in this population.

 

Conder, R., Zamani, R. and Akrami, M. (2019). The Biomechanics of Pregnancy: A Systematic Review. Journal of Functional Morphology and Kinesiology, 4(4), pp.72-87.

 

KEY POINTS: BIOMECHANICS OF PREGNANCY

  • Most statistically significant results are found in the third trimester.
  • While anterior pelvic tilt, lumbar lordosis, and thoracic kyphosis increase during pregnancy, this wasn’t consistent across studies, and is therefore likely related to individual factors.
  • Back pain during pregnancy is not related to spinal changes.

Postural control is decreased during pregnancy. However, stability is increased by the third trimester.

  • During pregnancy, the risk of falls increases due to decreases in postural control and stability.
  • Falls risk is increased in pregnant women who demonstrate decreased ankle...
