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).
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.
Knee to chest stretch - Lying down on the back, bring one leg up and pull it towards the chest and hold for 30–45 seconds. Posterior pelvic tilt (bridges) - Lying on the back, bend both legs and place your feet on the floor. Raise stomach from the ground, lifting the back and pelvis, until the back is straight. Hold for 5–10 seconds and relax.
Distraction tests: positive tests are rechecked when the patient's attention is distracted, such as a straight leg raise test; Regional disturbances: regional weakness or sensory changes which deviate from accepted neuroanatomy; Overreaction: subjective signs regarding the patient's demeanor and reaction to testing
The hand is grasped like a handshake and the arm is moved in various directions to determine the tone. [1] The tone is the baseline contractions of the muscles at rest. The tone may be normal or abnormal which would indicate an underlying pathology. The tone could be lower than normal (floppy) or it could be higher (stiff or rigid).
A neurological examination is the assessment of sensory neuron and motor responses, especially reflexes, to determine whether the nervous system is impaired. This typically includes a physical examination and a review of the patient's medical history, [1] but not deeper investigation such as neuroimaging.
The most used ones are the FADIR test (flexion, adduction, and internal rotation), [5] [8] seated piriformis challenge test, [5] [6] [8] and the active piriformis test. [ 5 ] [ 8 ] [ 2 ] Additional tests include Lasegue test (known as the straight leg raise test), Pace's sign, Freiberg's sign, and the Beatty test.
On inspection the clinician looks for signs of: trauma; previous surgery ()muscle wasting/muscle asymmetry; edema (swelling) erythema (redness); ulcers – arterial ulcers tend to be on the borders / sides of the foot, neuropathic ulcers on the plantar surface of the foot, venous ulcers tend on be on the medial aspect of the leg superior to the medial malleolus.
