Buerger's test is performed in an assessment of arterial sufficiency. It is named after Leo Buerger . The vascular angle , which is also called Buerger's angle , is the angle to which the leg has to be raised before it becomes pale, whilst lying down .
Involuntary extension of the "normal" leg occurs when flexing the contralateral leg against resistance. To perform the test, the examiner should hold one hand under the heel of the "normal" limb and ask the patient to flex the contralateral hip against resistance (while the patient is supine), asking the patient to keep the weak leg straight while raising it.
Ankle-brachial pressure index (ABPI) assesses peripheral vascular disease. It may however be unreliable in patients with calcified arteries in the calf (often diabetic patients) or those with extensive oedema , in which case toe pressure or Toe-brachial pressure index (TBPI) should be measured to aid in the diagnosis.
The Hubscher maneuver (or Jack's test) is a method of evaluating the flexibility of a pes planus or flat foot type. The test is performed with the patient weight bearing , with the foot flat on the ground, while the clinician dorsiflexes the hallux and watches for an increasing concavity of the Arches of the foot.
The straight leg raise is a test that can be performed during a physical examination, with the leg being lifted actively by the patient or passively by the clinician. If the straight leg raise is done actively by the patient, it is a test of functional leg strength, particularly the rectus femoris element of the quadriceps (checking both hip flexion and knee extension strength simultaneously).
Evidence supports the rules as an accurate instrument for excluding fractures of the ankle and mid-foot, reducing the number of unnecessary investigations and length of stay in emergency departments. [3] The original study reported that the test was 100% sensitive and reduced the number of ankle X-rays by 36%. [4]

Mulder's sign is a physical exam finding associated with Morton's neuroma, which may be elicited while the patient is in the supine position on the examination table. The pain of the neuroma, as well as a click, can be produced by squeezing the two metatarsal heads together with one hand, while concomitantly putting pressure on the interdigital space with the other hand.
