Summary
Individuals with Turner syndrome (TS) exhibit impaired balance, particularly in complex tasks. Higher body weight in TS is linked to worse balance, increasing fall risk.
Area of Science:
- Endocrinology
- Neurology
- Orthopedics
Background:
- Turner syndrome (TS) is associated with clinical observations of impaired body balance.
- Previous assessments used basic clinical tests, necessitating more specific evaluations.
Purpose of the Study:
- To quantitatively assess postural balance in TS subjects using dynamic posturography.
- To investigate the relationship between balance performance and body composition in TS.
Main Methods:
- Nineteen TS subjects and 19 age/sex-matched controls underwent dynamic posturography (Equitest).
- Balance was tested under varying sensory and platform conditions (SO1-SO6).
- Body composition was analyzed using dual-energy X-ray absorptiometry (DXA).
Main Results:
- TS subjects performed similarly to controls in simpler balance tests (SO1-SO4).
- TS subjects showed significantly worse performance in challenging conditions on unstable platforms (SO5, SO6).
- Higher total body weight in TS correlated with poorer balance scores in difficult tests.
Conclusions:
- Turner syndrome is associated with impaired postural control, especially in complex sensory integration tasks.
- TS individuals may have an elevated risk of falls due to difficulties in managing coordination.
- Body composition, particularly high body weight, influences balance deficits in TS.

Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...

Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
