Methods Design: three group parallel trial 
 Purpose: study the effect of segmental vs. innocuous electrical stimulation for chronic pain relief
Participants Patients: patients with first acute stroke 
 Baseline comparability: NS
Interventions Placebo: stimulation from electrical stimulation device with disconnected circuit and standard rehabilitation 
 Untreated: standard rehabilitation only 
 Experimental: functional electrical stimulation and standard rehabilitation 
 (Co‐intervention: standard rehabilitation program)
Outcomes Composite spasticity scale (CSS) 
 Maximum isometric voluntary contraction (MIVC) 
 Walking ability (Up and Go (TUG) test)
Notes  
Risk of bias
Bias Authors' judgement Support for judgement
Adequate sequence generation? Low risk 'random number produced by Jensen's computerized method of minimization'
Blinding? 
 Treatment provider High risk Described as single‐blind (placebo/electrical stimulus device)
Blinding? 
 Outcome assessor Low risk '... the assessor was blinded to the nature of intervention'
Incomplete outcome data addressed? 
 All outcomes Low risk Drop‐out < 15%
Free of selective reporting? Unclear risk No protocol available
Free of other bias? Low risk  
Trial size > 49? High risk N = 28
Clearly concealed allocation + trial size > 49 + drop‐out max 15% High risk Trial size < 49
