Medical diagram showing 4 types of strabismus (squint): Esotropia (eye turns inward/nasal), Exotropia (eye turns outward), Hypertropia (eye turns upward), Hypotropia (eye turns downward). Each type shown as a pair of eyes with arrows indicating direction of deviation. Clean medical illustration style with labels.

Medical diagram of Chaddock's sign: A foot shown from the lateral side with a blunt instrument stroking below the lateral malleolus (outer ankle bone). Arrow showing direction of stimulus along the lateral dorsum of foot. Second panel showing positive response - big toe extending upward (dorsiflexion). Label: "Stimulus: sub-malleolar lateral foot" and "Positive: Big toe extension = UMN lesion". Clean clinical illustration.

ECG strip showing Atrial Fibrillation: irregularly irregular RR intervals, no visible P waves, fibrillatory baseline (chaotic f waves between QRS complexes), narrow QRS complexes at varying intervals. Labeled with: "No P waves", "Irregular RR intervals", "Fibrillatory baseline". Clean medical ECG graph on grid paper background.

Medical illustration of Ape Hand deformity (median nerve palsy): Hand shown with thumb permanently adducted and flattened thenar eminence, thumb in same plane as fingers (cannot oppose). Label: "Ape Hand - Median Nerve Palsy". Second panel showing normal hand with thumb in proper abducted position for comparison. Anatomy labels: thenar wasting, adducted thumb, loss of opposition.

Medical illustration of Scoliometer being used during Adam's Forward Bend Test for scoliosis screening. Patient bending forward at 90 degrees with hands hanging down. Clinician placing scoliometer (inclinometer device) on the patient's back over the spine apex. Visible rib hump on one side showing trunk asymmetry. Label: "ATR = Angle of Trunk Rotation", "Positive if >7 degrees". Clean clinical diagram.

Medical illustration of 90-90 Straight Leg Raise test for hamstring tightness. Patient lying supine with hip flexed to 90 degrees and knee also flexed to 90 degrees. Therapist then extends the knee. Two panels: Normal (knee extends fully, popliteal angle near 0) and Positive (knee cannot straighten, large popliteal angle >20 degrees = tight hamstrings). Labels showing hip at 90, knee angle measurement, popliteal angle.

Medical illustration of Serratus Anterior Muscle Manual Muscle Testing (MMT). Three panels: 1) Grade 5/4: Patient supine, arm flexed to 90 degrees, therapist applies resistance at wrist while patient protracts scapula. 2) Grade 3: Wall push-up showing scapular winging (medial border of scapula lifts off chest wall). 3) Grade 2: Side-lying arm elevation. Labels showing serratus anterior muscle origin on ribs, long thoracic nerve C5-C7. Clear anatomical diagram.

Medical illustration showing Rheumatoid Arthritis hand deformities. Four panels: 1) Swan Neck deformity - PIP hyperextension + DIP flexion. 2) Boutonniere deformity - PIP flexion + DIP hyperextension. 3) Ulnar drift - fingers deviate toward ulnar side at MCP joints. 4) Z-thumb deformity - IP hyperextension + MCP flexion. Each deformity clearly labeled with joint positions. Clinical medical diagram style.

Medical diagram showing 6 types of pathological gait patterns. Each shown as a stick figure or silhouette walking: 1) Hemiplegic/Circumduction gait - stiff leg swinging in arc. 2) Steppage gait - high knee lift, foot drop. 3) Trendelenburg gait - hip dropping on swing side. 4) Scissors gait - knees crossing. 5) Parkinsonian - shuffling, stooped, festination. 6) Ataxic/Cerebellar - wide base, staggering. Each labeled clearly. Clean medical educational diagram.
