KEY POINTS: FAI MORPHOLOGY & ADOLESCENT SPINES

• There is a significant association between between spinal deformity and the presence of femoroacetabular impingement morphology. 

There was no relationship between femoroacetabular impingement morphology and spinopelvic parameters.

• Abnormal morphology or biomechanics in the pelvis or spine inherently affect each other by way of the lumbosacral junction.
• Changes in spinal alignment alter hip biomechanics and may also predispose an...

This small study compared the dynamic and static motor capacities of each finger among elderly individuals who engaged in hobbies that involved daily use of the hands, and those that did not.

Aoki T, and Kadota K. Effects of Daily Hand Activities on Age-Related Declines of Dynamic Motor Function in Individual Fingers. Motor Control (Ahead of Print). https://doi.org/10.1123/mc.2020-0085

KEY POINTS: HAND DEXTERITY & MOTOR FUNCTION

• Aging is characterized by a decline in manual dexterity, and may be quantified by decreased grip force, decreased tapping frequency, and prolonged timing for the pegboard test.
• Reports from static motor function studies on individual fingers show that the lower maximum pinch force in older adults is greatly reduced, compared with young adults.¹
  • Pinch force is a precision grip whereby an object is pinched in three ways: lateral pinch, three-point pinch, and two-point pinch.

GRIP & GRASP

• Grip and Grasp Anatomy: The carpals.
  
  • The carpus is designed to increase the tension in the tendons of the fingers (both extensors and flexors) and optimise these movements.
  • The proximal row are functionally separate from the distal row.
  • Flexion of the wrist initially occurs between these two rows, with the scaphoid acting as a bridge, so that in the final stage of flexion the whole carpus moves as a single unit.
  • The same occurs in...

WHAT IS SCOLIOSIS?

• Scoliosis is a side to side, three dimensional curve of the spine, involving curves in the sagittal, coronal, and transverse planes.
• In addition to the spinal curves, scoliosis also presents with a concave and  convex hemithorax.
•  Despite the fact that scoliosis exists in three dimensions, it is defined an measured by curves in the coronal plane.
  • for a diagnosis of Scoliosis, a patient needs to have a Cobb angle of more than ten degrees.
• Scoliosis affects the...

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: LOCOMOTION & DYNAMIC POSTURE

• 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 spinal/supraspinal loops, and the integration of various sensory inputs (e.g. proprioceptive, visual and vestibular) at various supraspinal levels resulting in long latency responses (p.8).
    
    
• Dynamic balance in limbed vertebrates requires proper coordination of all...

This study looked at knee joint biomechanics in a young, healthy population with no activity restrictions, with a focus on energy storage and return (ESAR)  prostheses. The authors recognise that the study had a small sample size, and discuss potential sources of error for their data collection, but are confident about the clinical application of their findings.

Orekhov G, Robinson AM, Hazelwood SJ, Klisch SM (2019) Knee joint biomechanics in transtibial amputees in gait, cycling, and elliptical training. PLoS ONE 14(12): e0226060.

KEY POINTS: KNEE BIOMECHANICS FOR TRANSTIBIAL AMPUTEES

• There is a high prevalence of joint pain and osteoarthritis (OA) in unilateral transtibial and transfemoral amputee populations.
• Transtibial amputees are more likely to develop OA in the intact knee.

Abnormal gait biomechanics include asymmetric ground reaction forces, muscle activation patterns, and knee joint kinetics between limbs.

OUR FEET AS OUR FOUNDATION

•  Pilates sessions traditionally begin with footwork and other strength work to set a foundation for movement.
• By spending time building strength through the feet, you can help to support a stable and dynamic support for standing, and for upright movement.
• This is an incredibly functional place to begin, and it's no different when working with a pregnant body.

 CLINICAL PILATES EMBODIED ANATOMY: FOOTWORK...

This study sought elucidate the influence that foot posture has on the relationship between toe flexor strength and functional performance in older adults. The authors recognise the study's limitations: the study cohort was limited to women, and did not measure body kinematics or muscle activity.

Kusagawa, Y., Kurihara, T., Imai, A., Maeo, S., Sugiyama, T., Kanehisa, H., & Isaka, T. (2020). Toe flexor strength is associated with mobility in older adults with pronated and supinated feet but not with neutral feet. Journal of foot and ankle research, 13(1), 55. https://doi.org/10.1186/s13047-020-00422-y

KEY POINTS: TOE FLEXOR STRENGTH & MOBILITY IN OLDER ADULTS

• Both pronated and supinated foot postures influence rearfoot frontal plane motion, plantar pressure distribution, and muscle activity in the lower limb during gait.
• Individuals with pronated feet require increased intrinsic muscle activity to stabilize the...

WHAT IS AXIAL ELONGATION?

• Many Pilates courses extol the virtues of axial elongation, and teach this principle as an elongation of the spine: creating space between the vertebrae.
  • Axial elongation opens space between the joints, and thus creates space for movement.
  • This space between the joints helps to decompress joints and rebalance the soft tissues around those joints. 
• Axial elongation can also be used along the axes of the long bones, or between any other joints in the body.
  • Wherever there is an...
