Strengths and limitations
PD, TVT
This is the first qualitative study to explore people with PD experiences and attitudes towards visuo-cognitive rehabilitation using novel technology versus more traditional approaches. There were a number of strengths of this study. First, the cross-over design allowed a unique insight into the opinions of people with PD who had the opportunity to experience both approaches to treatment. Second, use of NPT to frame the data analysis allowed a theoretical approach to determining factors that influence the successful implementation of a TVT rehabilitation programme. The authors acknowledge that there is some overlap between the themes and the constructs. However, the application of NPT is designed to be flexible to allow non-linear analysis which helped us understand and add context to the processes of implementation and embedding technology into home-based care for people with PD [There were also several limitations to our study. The same research physiotherapist who delivered the interventions also conducted the interviews. This may have impacted on participant responses in the interviews and therefore there is a risk of bias in the findings. However, this method allows for a thorough understanding of the material as it is through the researcher’s facilitative interaction that a context is created where respondents are set at ease and share rich data regarding their experiences [Finally, only people with PD were involved in the interviews. Successful implementation of new technology depends on the acceptability of the intervention from a perspective of all stakeholders and therefore it would be useful to consider clinician feedback in any future studies exploring the use of TVT [
