摘要

TLDRThis video introduces the basics of osteokinematics, focusing on how to describe joint movements using anatomical planes and axes. It explains the sagittal, frontal, and transversal planes, detailing the movements associated with each. The shoulder and hip joints, both ball and socket joints, have three degrees of freedom, allowing various movements including flexion, extension, abduction, adduction, and rotation. In contrast, the knee is a hinge joint with a single degree of freedom, enabling only flexion and extension. Understanding these concepts is crucial for physiotherapy and movement analysis.

    In this video introduction to osteokinematics, Kai explains the fundamental concepts of movement through the use of anatomical planes and axes. The body is examined starting from the anatomic position, describing the sagittal, frontal, and transversal planes, each of which relates to specific axes of rotation. The discussion highlights the importance of understanding joint movement mechanics, illustrating these principles through the example of shoulder, hip, and knee joints. The shoulder and hip joints are identified as ball-and-socket joints with three degrees of freedom, allowing for various movements, while the knee joint is described as a hinge joint with only one degree of freedom, allowing only flexion and extension.

视频问答

  • What are the three anatomical planes?

    The three anatomical planes are the sagittal plane, frontal plane, and transversal (horizontal) plane.

  • How does movement occur around anatomical axes?

    Movement occurs around specific axes of rotation that are perpendicular to the anatomical planes.

  • What movements are associated with the shoulder joint?

    Shoulder joint movements include flexion, extension, abduction, adduction, and internal/external rotation.

  • What is the degree of freedom for the knee joint?

    The knee joint has one degree of freedom, allowing only flexion and extension.

  • How many degrees of freedom does the hip joint have?

    The hip joint has three degrees of freedom, allowing movement in all three planes.

  • What is the significance of osteokinematics in physiotherapy?

    Osteokinematics helps in understanding how joints move, which is essential for assessment and treatment in physiotherapy.

    hi and welcome to Physio tutors my name
  • 00:00:10
    is Kai and uh today we would like to
  • 00:00:13
    explain you the basics of
  • 00:00:16
    osteokinematics in fact we would like to
  • 00:00:18
    explain you how to use planes and axes
  • 00:00:22
    in order to describe certain movements
  • 00:00:24
    for our explanations we will always
  • 00:00:26
    start in the anatomic
  • 00:00:28
    position the Cal plane divides the body
  • 00:00:32
    into right and left
  • 00:00:35
    sections the frontal plane is dividing
  • 00:00:38
    the body into a front and a back
  • 00:00:43
    section the transversal or horizontal
  • 00:00:46
    plane divides the body into an upper and
  • 00:00:50
    a lower
  • 00:00:52
    half when a movement takes place in a
  • 00:00:55
    plane bones rotate around an axis of
  • 00:00:59
    rotation
  • 00:01:00
    for example to describe a movement in A
  • 00:01:03
    sagittal plane we are seeing a rotation
  • 00:01:07
    around or perpendicular to the
  • 00:01:10
    transversal also called frontal
  • 00:01:14
    axis when we see a movement in the
  • 00:01:16
    frontal plane we are describing a
  • 00:01:19
    rotation around the sagittal
  • 00:01:22
    axis and lastly in the transversal or
  • 00:01:25
    horizontal plane we describe a movement
  • 00:01:29
    around the long long itudinal
  • 00:01:32
    AES during an inspection of a movement
  • 00:01:35
    in a certain plane you should take the
  • 00:01:38
    following
  • 00:01:39
    position perpendicular to the plane of
  • 00:01:42
    movement which means in the extension of
  • 00:01:45
    the AIS around which the movement takes
  • 00:01:50
    place to illustrate these Concepts we
  • 00:01:53
    will give you three
  • 00:01:57
    examples shoulder joint
  • 00:02:00
    before you describe the movements in a
  • 00:02:02
    joint you should ask yourself how many
  • 00:02:05
    levels of Freedom this joint has as a
  • 00:02:08
    shoulder joint is a ball and socket
  • 00:02:10
    joint morphologically and functionally
  • 00:02:13
    its level of freedom is three which
  • 00:02:16
    means it can move in all three planes if
  • 00:02:19
    we are moving the shoulder in A sagittal
  • 00:02:22
    plane we are moving around the
  • 00:02:24
    transversal
  • 00:02:26
    axis these movements in the shoulder
  • 00:02:28
    joint are called flection or antiv
  • 00:02:32
    verion and extension or
  • 00:02:36
    retroversion if we are moving the
  • 00:02:38
    shoulder in a frontal plane we are
  • 00:02:41
    moving around the sagittal
  • 00:02:44
    axis these movements are called AB
  • 00:02:48
    duction and AD
  • 00:02:54
    duction the movements of the shoulder in
  • 00:02:57
    a transversal plane around the
  • 00:02:59
    longitudinal axis are called
  • 00:03:02
    external or lateral
  • 00:03:05
    rotation and internal or medial
  • 00:03:10
    rotation hip
  • 00:03:12
    joint the hip joint is a ball and socket
  • 00:03:15
    joint as well and therefore has also
  • 00:03:17
    three degrees of
  • 00:03:19
    freedom if we are moving the hip in A
  • 00:03:21
    sagittal plane we are moving around the
  • 00:03:24
    transversal axis these movements are
  • 00:03:27
    called
  • 00:03:28
    flexion
  • 00:03:31
    and
  • 00:03:35
    extension if we are moving the hip in a
  • 00:03:37
    frontal
  • 00:03:38
    plane we are moving around the sagittal
  • 00:03:41
    axis these movements are called AB
  • 00:03:46
    duction and a
  • 00:03:52
    deduction the movements of the hip in a
  • 00:03:54
    transversal plane around the
  • 00:03:56
    longitudinal axis are called EX external
  • 00:04:00
    or lateral
  • 00:04:02
    rotation and internal or medial
  • 00:04:08
    rotation knee joint to give you an
  • 00:04:11
    example of a joint that does not have
  • 00:04:13
    all possible three degrees of freedom we
  • 00:04:16
    will take the knee joint the knee joint
  • 00:04:19
    is morphologically and functionally a
  • 00:04:21
    hinge joint which means it only has one
  • 00:04:24
    degree of Freedom it can only move in
  • 00:04:27
    one
  • 00:04:28
    plane the only two movements that can
  • 00:04:31
    happen in the knee joint are
  • 00:04:33
    flexion and
  • 00:04:36
    extension as we have learned these two
  • 00:04:38
    movements always take place in A
  • 00:04:40
    sagittal
  • 00:04:41
    plane the two movements of the frontal
  • 00:04:43
    plane which are AB duction and a
  • 00:04:46
    deduction are hardly possible the two
  • 00:04:49
    movements of the transversal plane which
  • 00:04:51
    are internal and external rotation are
  • 00:04:53
    also not possible in the knee joint this
  • 00:04:56
    was a short introduction into
  • 00:04:58
    osteokinematics
