Benign Paroxysmal Positional Vertigo Sample Clauses

Benign Paroxysmal Positional Vertigo. This thesis did not include people with fluctuating symptoms such as MD (Xxxxx-Xxxxxxx et al., 2015) and acute BPPV (Xxxxxxxxxxxxx et al., 2017). However, people with history of previous recurrent BPPV episodes, were included, if they experience postural unsteadiness despite following successful treatment with the repositioning manoeuvres (xx Xxxxxxxx et al., 1998; xx Xxxxxxxx et al., 2000; Xxxxx et al., 2000). BPPV is one of the most commonly occurring peripheral vestibular disorder, with a lifetime prevalence of 2.4% (Xxxxxxxxxxxxx et al., 2017) and characterised by acute, short-lived attacks of severe vertigo brought about by sudden head movements, turning over in bed, and getting in and out of bed. Other symptoms may include external vertigo (e.g., the visual sense the surrounded environment is moving that often accompanies the internal vestibular sense), unsteadiness, and vegetative symptoms such as nausea, sweating, and tachycardia (Xxxxxxxx et al., 2009; von Xxxxxxx et al., 2015). Many people who have recurrent episodes of BPPV, may show multiple deficits including postural instability (Xxxxx et al., 2000), psychological symptoms such as anxiety, depression, or fear avoidance of movement (Xxxxx et al., 2018; Xxx et al., 2018), reduced PA levels (Xxx and Xxxxxxxxxxxxx et al., 2014) or sleep problems (Shih et al., 2018) even between the episodes. Recent studies observed that especially older adults are prone to develop BPPV (Xxxxxxxx et al., 2018; Xxxxxxx et al., 2021). They may be also more likely to experience remaining balance difficulties and worse scores on DHI (Xxx et al., 2019). The higher incidence of BPPV may be partially due to dysfunction of the utricle (Xxxxxxxx et al., 2018) but also perhaps because older adults are less active (Xxxxxxx-Xxxxx et al., 2020). A study found that older adults were 2.5 times more likely to have utricular dysfunction than younger controls (Xxxxxxxx et al., 2018). Traditionally, in people with BPPV there is a variety of simple and effective techniques (e.g., Epley, Sémont, Xxxxxx-Xxxxxx, and self-Xxxxx) available for treatment according to the semicircular canal which is affected by the condition (Xxxxxx and Xxxxxx, 1980; Xxxxxx et al., 1988; Xxxxx, 1992; Xxxxxx et al., 2004). However, the selection of technique and the provision of any additional balance and gait training should be based on a multifactorial assessment of the person with BPPV (Xxxxxxx et al., 1993; Xxxxxxx et al., 2000b). Postural instability is...
