Physical Examination of Lower Extremity Physical Examination of Lower Extremity Objective 1. Principles of Physical Examination 2. Physical Examination Approach: - Hip & Thigh - Knee - Foot & Ankle Principles of Physical Examination 1. Do not forget the patient - General examination, Vital signs 2. Two sides: right and left 3. Two joints: above and below 4. Two surfaces: front and back Approach to Examination (Any Lower Extremity Joint) 1. General & Gait - General: Well or ill-looking - Vital signs: febrile, hemodynamic stability - Gait cycle - Abnormal gait: antalgic gait, Trendelenburg gait, steppage (foot drop) gait 2. Look (Inspection), Feel (Palpation) & Move (Motion) 3. Special Tests 4. Neurovascular Examination Hip & Thigh 1. Inspection for: - Leg length discrepancy - Alignment & Asymmetry (wasting) - Swelling, Skin changes (erythema), Scars 2. Palpation sites: - From the front: ASIS, pubic tubercle - From the side: greater trochanter - From the back: SI joint, PSIS 3. Motion: Hip Flexion: - Preferred Position: Supine with hips and knees in neutral rotation - Stabilization: Pelvis is stabilized by manual fixation - Goniometer Axis: Femoral Greater Trochanter - Reference (Stationary) Arm: Parallel to midaxillary line of the trunk - Movement (Movable) Arm: Parallel to longitudinal axis of the femur in line with lateral femoral condyle 2 Hip Extension: - Preferred Position: Prone with hips & knees in neutral and feet extending off end of the table - Stabilization: Pelvis is stabilized by manual fixation - Goniometer Axis: Femoral Greater Trochanter - Reference (Stationary) Arm: Parallel to midaxillary line of the trunk - Movement (Movable) Arm: Parallel to longitudinal axis of femur in line with lateral femoral condyle Hip Abduction: - Preferred Position: Supine with hips and knees in neutral and pelvis level - Stabilization: Pelvis is stabilized by manual fixation - Goniometer Axis: ASIS on measured side - Reference (Stationary) Arm: Along a line between the two anterior superior iliac spines - Movement (Movable) Arm: Parallel to the long axis of the femur Hip Adduction: - Preferred Position: Supine with the opposite extremity abducted - Stabilization: Pelvis is stabilized by manual fixation - Goniometer Axis ASIS on measured side - Reference (Stationary) Arm: Along a line between the two anterior superior iliac spines - Movement (Movable) Arm: Parallel to the long axis of the femur Hip Internal and External Rotation: - Preferred Position: Supine or sitting with the hip and knee flexed 90°. Opposite extremity abducted and resting on a foot stool - Stabilization: prevent thigh abduction/adduction - Goniometer Axis: mid-patella - Reference (Stationary) Arm: Perpendicular to the floor Alternate Test Position for Hip Internal/External Rotation: - Position: prone with knees flexed 90° - Stabilization: manual fixation of pelvis 4. Special tests: - Trendelenburg test: for abductor strength - Thomas test: for hip flexion contracture - Patrick’s (FABER) test: for SI joint - Anvil test & Rolling test: for hip pain Knee 1. Inspection for: - Leg length discrepancy: true leg length, apparent leg length - Alignment (varus, valgus) - Asymmetry (wasting): thigh circumference 3 - Swelling, Skin changes (erythema), Scars 2. Palpation sites: - Patella: margins and surfaces, quadriceps & patellar tendon & its insertion, bursae - Ligaments: medial & lateral collateral ligaments - Joint line: medial & lateral - Effusion: ballotment 3. Motion: Knee Flexion: - Preferred Position: Supine or reclined with hip and knee in neutral rotation - Stabilization: Trunk and pelvis stabilized by body weight and position - Goniometer Axis: Lateral epicondyle of the femur - Reference (Stationary) Arm: Parallel to the long axis of the femur & pointing at the greater trochanter - Movement (Movable) Arm: Parallel to the long axis of the fibula and pointing at the lateral malleolus Alternate Position: Prone lying with the femur stabilized. Knee flexion motion may be decreased as the rectus femoris is now stretched over two joints. Prevent substitute motion of hip abduction and/or hip flexion. Knee Extension: - Preferred Position: Supine with hips and knees in neutral rotation; distal leg on bolster - Stabilization: Trunk and pelvis stabilized by body weight and position - Goniometer Axis: Lateral Epicondyle of the femur - Reference (Stationary) Arm: Parallel to the long axis of the femur & pointing at the greater trochanter - Movement (Movable) Arm: Parallel to the long axis of the fibula and pointing at the lateral malleolus Alternate Position: Prone lying heel height technique 4.

  • Netter's Musculoskeletal Flash Cards, 1E
    Netter’s Musculoskeletal Flash Cards Jennifer Hart, PA-C, ATC Mark D. Miller, MD University of Virginia This page intentionally left blank Preface In a world dominated by electronics and gadgetry, learning from fl ash cards remains a reassuringly “tried and true” method of building knowledge. They taught us subtraction and multiplication tables when we were young, and here we use them to navigate the basics of musculoskeletal medicine. Netter illustrations are supplemented with clinical, radiographic, and arthroscopic images to review the most common musculoskeletal diseases. These cards provide the user with a steadfast tool for the very best kind of learning—that which is self directed. “Learning is not attained by chance, it must be sought for with ardor and attended to with diligence.” —Abigail Adams (1744–1818) “It’s that moment of dawning comprehension I live for!” —Calvin (Calvin and Hobbes) Jennifer Hart, PA-C, ATC Mark D.

Inspection • Posture – Erectness – Symmetry – Alignment • Skin and subcutaneous tissues – Swelling – Redness – Masses Inspection • Extremities – Size – Deformities – Enlargement – Alignment – Contour – Symmetry Inspection • Muscles – Bilateral symmetry – Hypertrophy – Atrophy – Fasciculations – Spasms Palpation • Palpate bones, joints, and surrounding muscles for the following: – Heat – Tenderness – Swelling – Fluctuation – Crepitus – Resistance to pressure – Muscle tone Muscles • Size and strength affected by the following: – Genetics – Exercise – Nutrition • Muscles move joints through range of motion (ROM). Muscle Strength • Compare bilateral muscles – Strength – Symmetry – Equality – Resistance End Feel Think About It!! • The sensation the examiner feels in the joint as it reaches the end of the range of motion of each passive movement • Bone to bone: This is hard, unyielding – normal would be elbow extension. • Soft–tissue approximation: yielding compression that stops further movement – elbow and knee flexion. End Feel • Tissue stretch: hard – springy type of movement with a slight give – toward the end of range of motion – most common type of normal end feel : knee extension and metacarpophalangeal joint extension. Abnormal End Feel • Muscle spasm: invoked by movement with a sudden dramatic arrest of movement often accompanied by pain - sudden hard – “vibrant twang” • Capsular: Similar to tissue stretch but it does not occur where one would expect – range of motion usually reduced.

  • Does Hip Contracture Effect Anterior Pelvic Tilt Changes During Squatting?
    38th International Society of Biomechanics in Sport Conference, Physical conference cancelled, Online Activities: July 20-24, 2020 DOES HIP CONTRACTURE EFFECT ANTERIOR PELVIC TILT CHANGES DURING SQUATTING? Bryan Christensen1, Katie Lyman1, Derrick Grieshaber1,2, Harlene Hatterman-Valenti1 North Dakota State University, Fargo, North Dakota, USA1 Fargo Force Ice Hockey Team, Fargo, ND, USA2 The purpose of this study was to examine possible effects of hip flexor contractures on changes in pelvic anterior tilt during the squat. Twenty recreationally active subjects were evaluated for hip contracture using the Modified Thomas test. Eight subjects were found to have iliopsoas contracture and twelve were found to have rectus femoris contracture. A 2x8 mixed-model repeated measures ANOVA was completed between the positive and negative hip contracture groups for both the iliopsoas and rectus femoris results. No significant differences were found between the hip contracture groups for the iliopsoas (p=.90) or the rectus femoris (p=.18). These results indicate the Modified Thomas test results about hip contracture do not have an effect on changes in pelvic motion during the squat. KEY WORDS: Hip flexors, iliopsoas, Modified Thomas Test, rectus femoris, squat INTRODUCTION: Flexibility and strength changes in muscles surrounding the body’s joints may affect posture and the chance of injury (Harvey, 1998; Winters et al., 2004; Zhu et al., 2010). Therefore, certified athletic trainers use special tests to evaluate the possiblility of injury or reinjury (Iversen et al., 2016; Winters et al., 2004). These tests can also be used to examine for abnormalities and the range of motion and flexibility of the hip/leg complex.
