Functional weakness is weakness of an arm or leg without evidence of damage or a disease of the nervous system. Patients with functional weakness experience symptoms of limb weakness which can be disabling and frightening such as problems walking or a 'heaviness' down one side, dropping things or a feeling that a limb just doesn't feel normal or 'part of them'.
Feeling this would indicate an organic cause of the paresis. If the examiner does not feel the "normal" leg's heel pushing down as the patient flexes the hip of the "weak" limb, then this suggests functional weakness (sometimes called "conversion disorder"), i.e. that effort is not being transmitted to either leg.

Frailty refers to an age-related functional decline and heightened state of vulnerability. It is a worsening of functional status compared to the normal physiological process of aging. It can refer to the combination of a decline of physical and physiological aspects of a human body.
Positive features of functional weakness on examination include Hoover's sign, when there is weakness of hip extension which normalizes with contralateral hip flexion. [17] Signs of functional tremor include entrainment and distractibility. The patient with tremor should be asked to copy rhythmical movements with one hand or foot.
Activity exercise-whether one is able to do daily activities normally without any problem, self care activities; Sleep rest-do they have hypersomnia, insomnia, do they have normal sleeping patterns; Cognitive-perceptual-assessment of neurological function is done to assess, check the person's ability to comprehend information
Weakness/paralysis of a limb or the entire body (hysterical paralysis or motor conversion disorders) Impairment or loss of speech (hysterical aphonia) Difficulty swallowing or a sensation of a lump in the throat; Urinary retention; Psychogenic non-epileptic seizures or convulsions; Persistent dystonia; Tremor, myoclonus or other movement disorders
These nursing actions can take place at any point in the patient's recovery. For example, the ICU nurse may put in a long-term disability referral for a patient who is likely to survive ICU with new physical deficits. Furthermore, a home care nurse could suggest a peer-support group for a PICS patient with new social dysfunctions.
There are many different functional disorder diagnoses that might be given depending on the symptom or syndrome that is most troublesome. There are many examples of symptoms that individuals may experience; some of these include persistent or recurrent pain, fatigue, weakness, shortness of breath or bowel problems.
