When I first learned about joint arthrokinematics, I had to figure out a way to visualize joint movements even though I couldn’t physically observe motion through the skin or muscles.I imagined a ball rolling along the inside of my cupped palm. Arthrokinematics 11 Norkin and Levengie 12. Now customize the name of a clipboard to store your clips. It is important to understand that the sternoclavicular joint is a saddle joint. Knee Joint Movement 101 -- Osteokinematics and Arthrokinematics There are two joints at the knee -- tibiofemoral and patellofemoral. Elbow flexion is an example of osteokinematics. The tibiofemoral (knee) joint allows 2 degrees of freedom, flexion and extension, and internal and external rotation. Range of motion (ROM) is determined by osteokinematics and arthrokinematics. External rotation to internal rotation= 2:1, Minimal rotation at 0 degrees of knee extension, Naming the rotation- based on orientation of tibial tuberosity in respect to anterior distal femur, Different from the rotation described earlier, In both closed or open kinematic chain, the knee joint laterally rotates (femur internal rotation in closed and tibia external rotation in open KC). The angular movement of bones in the human body occurs as a result of a combination of rolls, spins, and slides. )-asymmetrical muscle-sleep bruxism (grinding your teeth)-FHP (forward head posture) -joint wear at one spot will hurt in a particular area of knee flexion -when you start with full extension, the patella is a little above the joint line; at any point into flexion, different parts will be in contact, but at any time there's only about 30% of the posterior surface of the patella in contact with the intercondylar line Talocrural Joint: Arthrokinematics (closed chain) -Concave tibiofibular joint moving on convex talus (walking) -Dorsiflexion (initial contact; mid-stance to terminal stance/toe off) = concave tibiofibular joint rolls and glides anterior on talus ARTHROKINEMATICS is the general term for the specific movements of joint surfaces. Motion occurs from about 5 degrees of knee hyperextension to about 130 to 140 degrees of flexion. 'Arthrokinematics' refers to the movement of joint surfaces. - The description of motion : • Osteokinematics: the manner in which bones move • Arthrokinematics: movements occurring between joint surfaces. This range of motion is measured in degrees, using a goniometer. Human movement includes osteokinematics, or the movements of the bony levers of the body, along with arthrokinematics, which is the movement of the joint surfaces. ... -Knee flexion-fluid or edma. If the moving joint surface rolls on its partner without simultaneously gliding, the surfaces would separate (gap or subluxate) in some places and impinge in others. and med. Condyle act as pivot point while the lat. 1. The solid phase is somewhat permeable and when the articular surface is under load, the fluid gradually redistributes itself within the solid matrix. 24. 7. Review common positions and forces put on the knee joint. Knee Joint A double condyloid joint with 2degrees of freedom Flexion and extension / Medial and lateral rotation 0-120-150 degrees for flexion; Hyperextension 15 degrees 40. Define kinematics, osteokinematics, and arthrokinematics and give examples of the use of each of these terms and their relevance to studying kinesiology; Identify the cardinal planes of the body and be able to demonstrate movement in each of the three cardinal planes—sagittal, frontal, and transverse—and the axes for these motions; Radial deviators have LOA on the radial side of the wrist's AP axis. The foot is subdivided into the rearfoot, midfoot, and forefoot. Ligamentous restraint. I am a visual learner. The convex-concave rules of arthrokinematics have been taught in physical therapy schools in the United States for about 30 years. Arthrokinematics Talar dome is convex. the joint(s) that the muscle crosses the axis/axes of each of those joints the muscle's line of application (LOA) local to each of the axes. Understanding the normal osteokinematics, arthrokinematics, and muscle actions at the hip joint provides clinicians with the basic biomechanical background to detect impairments that may impact function and contribute to injury. • Automatic Locking/ Screw Home Phenomenon. Flexion and extension occur in the sagittal plane about a medial-lateral axis of rotation. Arthrokinematics & Joint Mobilization. Total rotation of about 40- 45 degrees. (Joint surface movements are sometimes called joint play motions or component motions). We speak as if this joint axis is a fixed point, as if the center of rotation is stationary like an automobile axle. -joint sounds-dec bite force-dec ROM-altered ROM-HA-joint locking-referred pain to face-referred pain to upper C/S (almost always associated) Causes:-stress-emotional-oral parafunctional habits (biting nails, chewing on ice, biting on a pen, etc. Osteokinematics. Femoral-on-pelvic and pelvic-on-femoral rotations occur in three planes. The SC joint is made up of the medial end of the clavicle, the manubrium and an articular disc in-between. Extensors have LOA dorsal/posterior to wrist's lateral axis. It gets its name from the shape as it has a concave surface in one direction and convex in another, like a saddle. Looks like you’ve clipped this slide to already. TibiofemoralArthrokinematics. Biomechanics introductory lecture for undergraduate year 1. See our Privacy Policy and User Agreement for details. of flexion, posterior glide on the medial side produces relative tibial internal rotation, a reversal of the screw-home mechanism. Also articular surface of medial condyle extends farther anteriorly than lateral condyle, the tibia is obliged to follow the laterally curved path into full tibial on femoral extension. rotation of tibia occurs at knee joint When lat. med. Therefore, the pressure within the fluid is strongly associated with the cushioning effect … If you continue browsing the site, you agree to the use of cookies on this website. Lecture 2 ... longitudinal axis of rotation extends as a straight line between the center of the femoral head and the center of the knee joint. Movement during the gait cycle. rotation of femur occurs at knee joint 38. basic/voluntarily joint movements, Ex. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. It is important to keep in mind that changes in capsule or ligament integrity will alter the normal mechanics of the shoulder joint. The articular cartilage of the patella is similar to that of other joints in that it contains a solid phase and a fluid phase that is mostly composed of collagen and glycosaminoglycans. The interpretation of the osteokinematics and arthrokinematics can also help guide the clinician in their treatment by revealing where stability is needed. Arthrokinematics. Medial condyle curves about 30 degrees laterally as it approaches intercondylar groove. Focuses on the manner in which bones move in space without regard to the movement of joint surfaces . • Knee joint complex • Biomechanical role in stability • Patella • Kinematics 1) Osteokinematics 2) Arthrokinematics • Kinetics Will Be Discussed 3. and med.

The osteokinematics of the right hip joint. • Tibiofemoral Osteokinematics My cupped palm creates a concave surface in which the convex ball can fit - just like a joint. The tibiofemoral joint experiences forces between the femur and tibia and operates as a modified hinge joint; whereas, the patellofemoral Knee joint complex • Largest joint, complex joint. Osteokinematics (osteo = bone; kinematics = motion) is the gross motion which occurs when bony segments move around a joint axis. We use OSTEOKINEMATIC terms, such as abduction or adduction, flexion or extension, to name the movements that occur between bones at synovial joints. Due to this infrequency, many will therapists simply refer out to specialists when these patients present. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Created by PTAONLY.com 2 Bones of the knee joint The knee is primarily made up of 4 bones; the femur, patella, fibula and tibia. The foot and ankle form a complex system which consists of 28 bones, 33 joints, 112 ligaments, controlled by 13 extrinsic and 21 intrinsic muscles. Tibiofemoral Joint See our User Agreement and Privacy Policy. A roll is a rotary movement, one bone rolling on another. biomechanic of knee joint 1. MUMBAI 2. internal rotation / external rotation. ... limit significant translation between the joint surfaces. It functions as a rigid structure for weight bearing and it can also function as a flexible structure to conform to uneven terrain. Osteokinematics 8 Naming the rotation- based on orientation of tibial tuberosity with respect to distal anterior femur Neumann, 2010 9. When the knee begins to flex from a position of full extension, posterior tibial glide begins first on the longer medial condyle. Osteokinematics. BIOMECHANICS OF KNEE JONT AKSHAY CHAVAN MPO 1st YEAR A.I.I.P.M.R. Roll and glide must occur simultaneously to preserve joint integrity. Clipping is a handy way to collect important slides you want to go back to later. The primary arthrokinematics of the tibiofemoral joint include roll, glide and spin. We can predict and understand the relationship between bony shapes at a joint surface and the surfaces' movements by applying the rules of concavity and convexity (Kaltenborn 1989, p.27). Osteokinematics of the Tibiofemoral Joint. Arthrokinematics. The ball is round, but in terms of arthrokinematics, the ball is considered convex.

Evolute is the curved path… that medial lateral axis takes, Axial rotation increases with knee flexion. The knee joint is one of the largest and most complex joints in the body. Each joint or articulation involves two bony surfaces, one that is convex and one that is concave. roll. Rolling is a sagittal plane rotation; gliding, a sagittal plane translation; and spin, a transverse plane rotation. Joint surfaces move with respect to one another by simultaneously (1) rolling, (2) gliding, and (3) spinning. small amplitude motions of bones at joint surface. Roll and glide, like all motions, are produced by forces. It is constructed by 4 bones and an extensive network of ligaments and muscles. The temporomandibular joint (TMJ) is one of the least commonly treated regions of the body in outpatient orthopaedics. Ankle (talocrural) joint Planes and axes of motion. Joint axes' locations are fairly stable, but only because the joint surfaces move in a very specific way. Study 15 Functional Anatomy- Osteokinematics vs. Arthokinematics flashcards from Breanna H. on StudyBlue. Many are unaware of the fact that the TMJ and cervical spine are connected by more than just proximity. • Tibiofemoral Arthokinematics The idea that the morphology of articular surfaces is strongly related to kinematics can be traced back to the works of MacConaill, 7, 8 Maitland, 10 MacConaill and Basmajian, 9 and Steindler. Sreeraj S R ARTHROKINEMATICS Axial rotation Longitudinal axis for axis rotation lies at medial intercondylar tubercle i.e. Osteokinematics 9 Variability: Age Gender 10. Classic explanations of movements occurring at the knee joint describe active motion as including flexion and extension, which occur around a transverse axis passing through the femoral condyles, and rotation of the tibia, which occurs around a longitudinal axis passing through the medial intercondylar tubercle. OSTEOKINEMATICS. Elbow and radio-ulnar arthrokinematics applying the rules of concavity and convexity to the humero-ulnar joint: in an open chain, concave ulnar surface rolls and glides in same direction on convex humeral surface.
