Physical Examination of the Ankle is inspected for deformities, swelling, skin discoloration, muscle atrophy, and asymmetry with the opposite side. The lower leg muscles are inspected for atrophy. Sensation to light touch is tested, at minimum, on the top of the first webbed space and the side of the foot. The dorsal pedal pulse is palpated over the anterior foot, and the posterior tibial pulse is palpated behind the medial malleolus.
The physical exam is of crucial importance for the clinical evaluation of painful conditions of the foot and ankle. These disorders are very common in the outpatient setting, both among professional athletes and recreational exercisers. It is important to be familiar with some basic maneuvers and physical signs necessary to assess the presence and the severity of lesions in the osteo-ligamentous structures of the foot.
The ankle is gently felt for warmth and to detect subtle swelling. Comparison to the unaffected side is useful. Palpation for tenderness is done over the bones and then the major ligaments. Touching only the bone, and then only the ligament, can help distinguish bony from ligamentous injury.
Laterally, palpation includes the tip of the lateral malleolus, the fibula, and the three lateral ligaments: anterior talofibular, posterior talofibular, and fibulocalcaneal. Because an inversion injury of the ankle can fracture the proximal fibula, the proximal fibula is palpated. The base of the 5th metatarsal is also palpated.

Different types of abnormal gaits
| Type of the gait | Physical findings and observations | Possible cause |
| Antalgic gait | The short stance phase of the affected side Decrease of the swing phase of the normal side | Pain on weight-bearing could be any reason from Back pathology to a toe problem, e.g., degenerative hip joint |
| Ataxic (stamping) gait | Unsteady and uncoordinated walk with a wide base | Cerebral cause Tabes dorsalis |
| Equinus (tiptoes) gait | Walking on tiptoes | Weak dorsiflexion and/or plantar contractures |
| Equinovarous gait | Walking on the out border of the foot | CETV |
| Hemiplegic (circumduction) gait | Moving the whole leg in a half-circle path | Spastic muscle |
| Rocking horse (gluteus maximum) gait | The body shifts backward at heel strike then move forward | Weak or hypotonic gluteus maximum |
| Quadriceps gait | The body leans forward with hyperextension of the knee in the affected side | Radiculopathy or spinal cord pathology |
| Scissoring gait | One leg crosses over the other | Bilateral spastic adductors |
| Short leg (Equinus) gait (more than 3 cm) | Minimum: Dropping the pelvis on the affected side Moderate: Walks on forefoot of the short limb Severe: Combination of both | Leg length discrepancy |
| Steppage gait (high stepping – slapping – foot drop) | No heel strike The foot lands on the floor with a sound like a slap | Foot drop Polio Tibialis anterior dysfunction |
| Trendelenburg (lurching) gait | Trunk deviation towards the normal side When the foot of the affected side leaves the floor, the pelvis on this side drops | Weak gluteus medius |
| Waddling gait | Lateral deviation of the trunk with an exaggerated elevation of the hip | Muscular dystrophy |
Examination techniques of muscles functions[rx]
| Muscle | Ankle position | Manoeuvre of the test |
| Tibialis Anterior | Maximum Dorsiflexion and inversion | Try to plantarflex the ankle with your hand and ask the patient to resist, use your second hand on the tendon to feel the contraction |
| Tibialis posterior | Plantar flexion and inversion | The patient inverts the foot in full plantar flexion whilst the examiner pushes laterally against the medial border of the patient’s foot (in an attempt to evert the foot). The examiner needs to use a second hand on the tendon to feel the contraction |
| Peroneal longus and peroneal brevis | Plantar flexion and eversion | The patient everts the foot in full plantar flexion and the examiner pushes medially against the lateral border of the patient’s foot (in an attempt to invert the foot) |
| Extensor hallucis longus | Neutral | The patient extends the great toe and the examiner try to plantarflex it |
| Extensor digitorum longus | Neutral | The patient extends the lesser toes toe and the examiner try to plantar flex it |
| Flexor hallucis longus and flexor digitorum longus | Neutral | The patient curls the toes downward and the examiner tries to dorsiflex them1 |
