---|---|---|---|
Zeman & Yiannikas 1989 [6] | 35 | Median SEP | Abnormal SEP (absence or amplitude reduction or prolonged latency N20) were associated with poor outcome (lower BI) after a mean LOS of 51 days |
Kovala 1991 [7] | 35 | Median and tibial SEP | Tibial SEP: correlation between amplitude abnormalities (absence or attenuation) and occupational outcome after 1 y |
Median SEP: absence of N60 predicted poor outcome | |||
Cillessen et al. 1994 [8] | 55 | EEG in the acute stage | EEG (presence of delta and theta activity) predicted poor outcome after 1 year |
Ring, Bar & Abboud, 1999 [9] | 4 | VEP | Correlation between left-right asymmetry of VEP and functional outcome after a mean of 137 days inpatient rehabilitation |
Feys et al. 2000 [10] | 64 | Median SEP and upper limb MEP | Absence of SEP and MEP indicated poor outcome 2 months after stroke |
Steube, Wiethölter & Correll 2001 [11] | 100 | Lower limb MEP more than 4 weeks after stroke | Preserved MEP predicted good outcome (independence in walking) after 8 weeks of inpatient rehabilitation |
Tzvetanov & Rousseff 2003 [12]; | 94 | Median and tibial SEP | N20-P25 amplitude is of some predictive value (1 y outcome), but MRC is stronger predictor of functional outcome, P40 amplitude correlated with BI (r = 0.63) after 3 months |

Tsetanov, Rousseff & Atanassova 2005 [14] | |||
Al-Rawi, Hamdan & Abdul-Muttalib 2009 [15] | 22 | Median SEP | Correlation between SEP (N20 latency and amplitude) and 3-month outcome (BI, MRC) |
Pizzi et al. 2009 [16] | 52 | Upper limb MEP | In patients with severe paresis (MRC <2), absence of MEP were predictive of poor recovery |
