Objective:
To investigate the agreement between the self-reported and examiner-reported difficulties of patients with neuromuscular disorders (NMDs) in performing daily activities at home.
Design:
A comparison between 2 methods of administering a measurement instrument.
Setting:
Neuromuscular reference center in a university hospital.
Participants:
Adult patients (N=57) with diagnosed NMDs living at home.
Interventions:
Not applicable.
Main Outcome Measure:
The ACTIVLIM questionnaire.
Results:
The intraclass correlation coefficient, model 2,1 (ICC(2,1)), between the measures was very good (ICC(2,1)=.87), indicating a good agreement between self-perceived and observed measures.
Conclusions:
The use of ACTIVLIM as a self-reporting questionnaire is a valid method for assessing activity limitations in patients with NMD.
