Recent evidence indicates that independent training of individual joints of the arm with robots can be as effective as coordinated multi-joint arm training.

The design of such a robot is the aim of the work presented in this paper.</p><p><strong>Methods: </strong>An end-effector robot kinematic design was developed and the optimal robot link lengths were estimated using an optimization procedure.

The proposed robot has relaxed constraints on the relative positioning of the human limb with respect to the robot. The optimized link lengths chosen for the robot allow it to cover about 80% of the human limb's workspace, and possess good overall manipulability. The simple estimation procedure was demonstrated to estimate human limb parameters with low bias and variance.</p><p><strong>Discussion: </strong>The proposed robot with three actuated and three non-actuated degrees-of-freedom has a compact structure suitable for both the left and right arms without any change to its structure. The proposed automatic estimation procedure allows the robot to safely apply forces and impose movements to the human limb, without the need for any manual measurements. Such compact robots have the highest potential for clinical translation.</p>","PeriodicalId":43319,"journal":{"name":"Journal of Rehabilitation and Assistive Technologies Engineering","volume":"8 ","pages":"20556683211019866"},"PeriodicalIF":2.0,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/42/94/10.1177_20556683211019866.PMC8459188.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39475383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Campbell, et al., “OASIS I: Retrospective analysis of four different microprocessor knee types”, published in the Journal of Rehabilitation and Assistive Technology Engineering 2020, Volume 7, pages 1–10. We commend the authors for their impressive study that is a valuable contribution to the body of evidence as it confirms the generalizability of smaller studies with microprocessorcontrolled knees (MPK) to real-life conditions in a large sample and assessed injurious falls that may serve as a solid foundation for future costeffectiveness analyses. We congratulate the authors on the big achievement to have completed a study with 602 participants successfully. Nevertheless, we believe that some points in the paper require clarification. First, the authors refer to their study as “retrospective” as the most important aspect of the study design. However, we think it would be more important to note that the study design was crosssectional, which has considerable consequences for the interpretation of data and foundation of conclusions. By nature, cross-sectional study designs assess outcomes at only one point in time and, thus, do not allow for any conclusions on causal relationships to explain the results. Therefore, all the interpretations and conclusions offered by the authors should have been clearly marked as hypotheses that require further study to confirm or reject rather than facts supported by the results. Therefore, it would have been appropriate to also discuss other possible explanations for the results, especially in lieu of the claimed “absence of bias”. Second, as there is no information on the baseline status of the patients included, the study was unable to control for a potential clinician bias in the selection of the different MPK. If clinicians preferred a certain MPK for patients with increased risk of falling and lower baseline mobility, the “parity” of outcomes would conceal a clear difference in effects of the four MPK on injurious falls and mobility. This limitation is important as there is comparative evidence that has already demonstrated that there are meaningful technical and functional differences between the MPK (e.g. Bellmann et al., 2010; Thiele et al., 2014; Thiele et al., 2019; Bellmann et al., 2019). Thus, another hypothesis to explain the results could have been that the Hanger prosthetists apparently choose MPK wisely when fitting their patients, making sure that the final outcomes of patients with different levels of baseline mobility are not significantly different. Third, we find the use of the term “parity” confusing and scientifically inadequate. “Parity” is more of a legal rather than a scientific term. The established statistical approaches to compare the differential effects and outcomes of similar interventions are equivalence and non-inferiority. However,","PeriodicalId":43319,"journal":{"name":"Journal of Rehabilitation and Assistive Technologies Engineering","volume":"8 ","pages":"2055668320981355"},"PeriodicalIF":2.0,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2055668320981355","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39273174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, regarding the assertion that we refer to the retrospective nature of our study as the most important aspect of the study design, this is incorrect. It is specifically the cross-sectional nature of the study design that is most salient. The letter notes “cross-sectional study designs assess outcomes at only one point in time and, thus, do not allow for any conclusions on causal relationships to explain the results.” We would submit that we are very clear to not note causality, and indeed pose many statements in hypothetical context. For example, regarding findings with mobility, we have deliberately noted that the data would ‘suggest that when improved mobility is considered a primary aim for MPK prescription’ clinicians could consider all models of knees. The suggestive language is preferred over stronger, more absolute language. The authors of the letter later comment on the potential for clinically meaningful differences with relation to the findings for injurious falls despite lack of statistical significance. They suggest we “neglected” these differences, and that we “stopped short of drawing the conclusion.” We agree with the emphasis on clinically meaningful differences. However, the two statements made in the letter are contradictory as initially the letter places emphasis on posing discussion points more as hypotheses needing further testing. The language throughout the manuscript is consistent, the data would ‘suggest that when stability and falls reduction is considered a primary aim for MPK prescription’, clinicians may consider the C-Leg or Orion. Regarding “absence of bias,” we are misquoted in the letter. The manuscript specifically states “absent of potential bias due to manufacturer funding or publication.” Nowhere within the manuscript do we state that the study is without bias. As mentioned within the manuscript, the study design carries inherent biases such as selection bias, and our falls questionnaire is subject to recall bias. There is also potential for observation bias with patients performing outcomes for their clinicians. We contend, while manufacturers certainly publish studies with attempts at minimizing bias, there will always be a need for additional studies that would not carry the same potential for confirmation bias, or pressure of publication bias. In the second point of the letter, it is noted that the “study was unable to control for a potential clinician bias in the selection of the different MPK.” We acknowledged selection bias in the manuscript, but there is great value in the increased ecological validity when examining the outcomes of more than 600 MPK users. The third point raised in the letter","PeriodicalId":43319,"journal":{"name":"Journal of Rehabilitation and Assistive Technologies Engineering","volume":"8 ","pages":"20556683211022232"},"PeriodicalIF":2.0,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/20556683211022232","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39273176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
