In early to middle age, bone density and muscle mass are closely related. As adults age, skeletal muscle mass or bone density may begin to decline. This decline can lead to frailty and both have been identified as contributors to disability. [18] Muscle weakness makes it difficult to perform everyday activities, like getting into a bathtub.
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'.
Positive features of functional weakness on examination include Hoover's sign, when there is weakness of hip extension which normalizes with contralateral hip flexion. [16] Signs of functional tremor include entrainment and distractibility. The patient with tremor should be asked to copy rhythmical movements with one hand or foot.
Veronica Brown lived with chronic fatigue, depression, and anxiety for over 10 years before she learned they were early signs of Parkinson's disease. Here's how she found relief after diagnosis.

A number of expert groups have proposed an increase in dietary protein recommendations for older age groups to 1.0–1.2 g/kg body weight per day. [48] [49] Ensuring adequate nutrition in older adults is of interest in the prevention of sarcopenia and frailty, since it is a simple, low-cost treatment approach without major side effects. [50]
Inclusion body myositis (IBM) (/ m aɪ oʊ ˈ s aɪ t ɪ s /) (sometimes called sporadic inclusion body myositis, sIBM) is the most common inflammatory muscle disease in older adults. [2] The disease is characterized by slowly progressive weakness and wasting of both proximal muscles (located on or close to the torso ) and distal muscles (close ...
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.
