Although there seems to be no causality between cervical spine (CS) manipulation and major adverse events (MAE), it remains important that manual therapists try to prevent every potential MAE. Although the validity of positional testing for vertebrobasilar insufficiency (VBI) has been questioned, recently, the use of these tests was recommended. However, based on the low sensitivity of the VBI tests, which may result in too many false-negative results, the VBI tests seem to be less valuable in pre-manipulative screening. Moreover, because the VBI tests are unable to consistently produce a decreased blood flow in the contralateral vertebral artery in (healthy people), the underlying mechanism of the test may not be a valid construct. There are numerous cases reporting MAE after a negative VBI test, indicating that the VBI tests do not have a role in assessing the risk of serious neurovascular pathology, such as cervical arterial dissection, the most frequently described MAE after CS manipulation. Symptoms of VBI can be identified in the patient interview and should be considered as red flags or warning signs and require further medical investigation. VBI tests are not able to predict MAE and seem not to have any added value to the patient interview with regard to detecting VBI or another vascular pathology. Furthermore, a negative VBI test can be wrongly interpreted as 'safe to manipulate'. Therefore, the use of VBI tests cannot be recommended and should be abandoned.
Cervicale mobilisaties en manipulatiesworden frequent en effectief uitgevoerd bijpatiënten met nek- en hoofdpijn. Slechtszeer zelden is er sprake van een calamiteit(zware complicatie) na een cervicaletechniek. Premanipulatieve tests gerichtop arteriële integriteit en ligamentairestabiliteit lijken niet voldoende valide enniet voldoende betrouwbaar te zijn. Hetzou daarom waardevol zijn als patiëntenmet een verhoogd risico voorafgaande aaneen cervicale handeling geïdentificeerdkunnen worden aan de hand van specifiekekenmerken. In deze review wordende karakteristieken in kaart gebracht vanpatiënten, behandelaren, het behandelprocesen de complicaties.
Cervical spinal manipulation (CSM) and cervical mobilization are frequently used in patients with neck pain and headache. Pre-manipulative cervical instability and arterial integrity tests appear to be unreliable in identifying patients at risk for adverse events. It would be valuable if patients at risk could be identified by specific characteristics during the preliminary screening.Objective was to identify characteristics of 1) patients, 2) practitioners, 3) treatment process and 4) adverse events (AE) occurring after CSM or cervical mobilization.A systematic search was performed in PubMed, Embase, CINAHL, Web-of-science, AMED, and ICL (Index Chiropractic Literature) up to December 2014.Of the initial 1043 studies, 144 studies were included, containing 227 cases. 117 cases described male patients with a mean age of 45 (SD 12) and a mean age of 39 (SD 11) for females. Most patients were treated by chiropractors (66%). Manipulation was reported in 95% of the cases, and neck pain was the most frequent indication. Cervical arterial dissection (CAD) was reported in 57% (P = 0.21) of the cases and 45.8% had immediate onset symptoms. The overall distribution of gender for CAD is 55% (n = 71) for female and therefore opposite of the total AE.Patient characteristics were described poorly. No clear patient profile, related to the risk of AE after CSM, could be extracted. However, women seem more at risk for CAD. There seems to be under-reporting of cases. Further research should focus on a more uniform and complete registration of AE using standardized terminology.
