This maybe particularly apparent if the individual is resistant to movement due to the anticipation of vertigo and nausea. If an individual’s history is consistent with BPPV and the DHT is negative, the Supine Roll Test should be performed to EPZ-6438 ic50 investigate the involvement of the horizontal semicircular canal (Bhattacharyya et al 2008). This may be the cause in 8% of BPPV cases (Stavros et al 2002). Belafsky et al (2005) suggest that the DHT is highly specific; however, its sensitivity is unknown. An Australian study of 2751 participants found that individuals with vestibular-dizziness

reported notably higher emotional and functional scores, as assessed by the Dizziness www.selleckchem.com/products/LBH-589.html Handicap Inventory compared to non-vestibular participants. The authors concluded that vestibular vertigo contributes to increased emotional distress and activity limitation therefore reducing quality of life for these individuals (Gopinath et al 2009). As the DHT requires a good range of movement it may not be suitable for use on individuals with certain neck pathologies. Absolute contra-indications include cervical instability, cervical disc prolapse, acute neck trauma and circulatory problems like VBI and carotid sinus syncope.

However the challenge for the clinician is to determine what constitutes a relative contra-indication in each case. Humphriss PD184352 (CI-1040) et al (2003) suggest a brief assessment of neck movements into rotation and extension and seeing if the position can be comfortably maintained for 30 seconds before conducting the DHT. If neck movement is limited or painful, the Side Lying Test may be a suitable alternative (Humphriss

et al 2003). The benefit of the DHT is that it is a simple assessment that can be conducted in a few minutes with minimal equipment and will definitively determine the presence of BPPV. Following a positive response, BPPV may be treated with the Epley Manoeuvre which, in most cases, provides instantaneous relief from BPPV symptoms and their associated impact on an individual’s life (Von Brevern et al 2003). “
“Active Straight Leg Raise (ASLR) is a functional test that is primarily used to diagnose pregnancy-related posterior pelvic pain (PPPP). The test is based on the observation that an immediate improvement in pain and the ability to lift the leg can often be provided for women with PPPP by pushing the hips together with hands (Mens et al 1999). ASLR is performed in a relaxed supine position with legs straight and feet apart. Patients are instructed to raise their legs 5–20 cm above the bench, one after the other, without bending the knee and without pelvic movement relative to the trunk.
