chronic stroke upper limb disability
MINOR, RECRUITMENT
The study was limited to four week period and two patients from the total sample of 108 were unable to participate due to the Lock-down in the country during the Covid-19 pandemic. Patients were recruited from the Teaching Hospital, Peradeniya, Sri Lanka, but due to the availability of electrical modalities they were asked to come to the Patient’s Service Unit, Department of Physiotherapy, Faculty of Allied Health Sciences, University of Peradeniya. The treatment site was 3km distant from the patient recruitment site, which we can consider as a limitation of the study, as patients needed to travel one site to the other. Blinding and objective assessment of the patients were conducted by one another physiotherapist at the treatment site, if she is on a leave, another physiotherapist was asked to do that. It may has a minor affection on the study protocol. We were not able to work on prognostic factors of the chronic stroke upper limb disability which is another limitation of our study. And also we were unable to compensate the patients since there were no available funds to support this study.
