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.
Hypotonia is a state of low muscle tone [1] (the amount of tension or resistance to stretch in a muscle), often involving reduced muscle strength. Hypotonia is not a specific medical disorder, but a potential manifestation of many different diseases and disorders that affect motor nerve control by the brain or muscle strength.
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).

The strength of the urethra can also be tested during this phase, using a cough or Valsalva maneuver, to confirm genuine stress incontinence. Urethral pressure profilometry: measures strength of sphincter contraction. [7] Electromyography (EMG) measurement of electrical activity in the bladder neck.
Simulation tests: these are based on movements which produce pain, without actually causing that movement, such as axial loading and pain on simulated rotation; Distraction tests: positive tests are rechecked when the patient's attention is distracted, such as a straight leg raise test
Swimming classification generally has three components. The first is a bench test which tests strength levels. The second is water test to assess how the swimmer performs each stroke. The third is in competition observation. [55] As part of the water test, swimmers are often required to demonstrate their swimming technique for all four strokes.
Muscle weakness is a lack of muscle strength. Its causes are many and can be divided into conditions that have either true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy.
