Assessing Human-Human Kinematics for the Implementation of Robot-Assisted Physical Therapy in Humanoids: A Pilot Study

The development of humanoids with bimanual manipulator arms may facilitate assistive robots to perform physical therapy with older adults living at home. As we assume the human-human interaction to be the gold standard of physical therapy, we propose a kinematics analysis to derive guidelines for implementing physical therapy assisted by humanoids. Therefore, a pilot study was carried out involving three physical therapists and two participants acting as exemplary patients. The study analyzes the therapists' movement strategy, including the position and orientation of the therapists' bodies in relation to the participants and the placement of the therapists' hands on the upper limb segment of the participants, as well as the inter- and intravariability during the performance of a ROM (range of motion) assessment. The results demonstrate that while physical therapists exhibit variation in their interaction strategies, they still achieve a consistently low level of variability in their manipulation space.

Predictors of Rehabilitation Outcomes: A Comparison of Israeli and Italian Geriatric Post-Acute Care (PAC) Facilities Using the Minimum Data Set (MDS)

OBJECTIVES

To understand the relative contribution of sociodemographic, clinical, and health care features to rehabilitation outcomes in Israel and in Italy in post-acute care (PAC) facilities.

DESIGN

Prospective cross-national study

SETTING

Two hospital geriatric PAC departments: Harzfeld Geriatric Hospital, Gedera, Israel, and Catholic University of Sacred Heart Geriatric Hospital, Rome, Italy.

PARTICIPANTS

Post-acute care patients aged 65 and older admitted consecutively for stabilization, improvement, or rehabilitation to 3 departments in Harzfeld Geriatric Hospital, Gedera, Israel from April, 1999 through February, 2002 (N = 364), and to the post-acute Geriatric Rehabilitation Unit of the "A. Gemelli" Hospital, Catholic University of Sacred Heart, Rome, Italy, between February, 1999, and April, 2002 (N = 351), for whom there were complete assessments at admission and discharge (the total number admitted in Israel was 505, and in Italy, 409).

MEASUREMENTS

Minimum Data Set for Post-Acute Care (MDS-PAC) assessments conducted within 4 days of admission and at discharge; data collected identically in both sites. Predictors of functional recovery> were identified using multivariate binary logistic regression. The dependent variable: improvement of 1 or more points in the ADL scale.

RESULTS

The staffing pattern of the PAC department in Italy had about double the physicians and physio- and occupational therapists than in Israel, but about the same number of nurses and somewhat fewer aides than in Israel. Multivariate binary logistic regression that includes country, age, sex, and marital status, found that the patients in Italy had about triple the probability of improvement in ADL function (OR 3.3, CI 2.4-4.6) (P < .001) than PAC patients in Israel. Even after health system characteristics were added to the model, ADL improvement was most significantly associated with higher cognitive ability and a diagnosis of hip fracture, as well as longer length of stay and being admitted to PAC directly from an acute hospital. For each additional point (worse cognition) in a cognitive scale, there was a 30% decrease in the probability of ADL improvement (OR 0.7, CI 0.6-0.8, P < .001). Those who had a stroke were about half as likely to show ADL improvement (OR 0.5, CI 0.3-0.7) than those without stroke, but those with a hip fracture had more than double the probability of ADL improvement (OR 2.7, CI 1.7-4.2) than those without hip fracture. Those who stayed in the PAC ward an additional block of time had a 30% higher probability of ADL improvement (P < .1), and those who were admitted directly to PAC from an acute hospital had more than 4 times the probability of ADL improvement (OR 4.1, CI 2.3-7.0, P < .001) than those who were admitted from a private home.

CONCLUSIONS

We found support for the hypothesis that differences in sociodemographic and clinical factors cannot account for all differences in ADL improvement, and that the organization of care and constraints of the health system also influence functional outcomes. Policymakers should examine the policy-amenable features of the Italian and Israeli systems so that optimal ADL recovery can be encouraged. Any reduction in disability will help both patients and the health care system; slightly higher short-term PAC treatment costs may have large long-term future benefits, if they result in the reduction of ADL disability. This study is one of the first to examine outcomes of PAC in 2 countries, and can provide an initial assessment of how rehabilitation can be enhanced or limited by health policies and staffing patterns.

Development of a conceptual framework for the assessment of geriatric rehabilitation outcomes

The objective of the study was to develop a conceptual framework of key assessment areas for the evaluation of rehabilitation outcomes in older persons. The study was designed in four stages. First, a review of the literature generated a list of 84 potential outcome variables. Second, semi-structured interviews were conducted with older adults informants (n = 19) to record their thoughts about important rehabilitation outcomes. From the analyses of the transcripts, 20 recurrent themes became apparent. Third, relevant assessment areas were determined based on the merged data from the literature and the interviews. Fourth, a focus group was held with a panel of eight interdisciplinary experts with strong involvement in geriatric rehabilitation to evaluate, improve, and validate the preliminary work. As a result of the study, the conceptual framework for the assessment of geriatric rehabilitation outcomes (FAGRO) is composed of four primary outcome domains related to important activities for community-living older persons: mobility activities, basic activities of daily living, activities of independent living, and leisure activities. The models also allows for four brief evaluations of underlying functioning components, including: physical functioning, psychological functioning, social functioning, and factors related to the caregiver status and available resources. The model has the potential to become a valuable additional tool for outcome assessment, researched and developed specifically for geriatric rehabilitation.

Risk Adjusting Rehabilitation Outcomes

The complexity and mix of rehabilitation patients varies across clinicians and institutions. Comparisons of outcomes across providers must therefore adjust for differences in risk factors across patient populations. Research on risk adjustment has generally focused on acute care hospital outcomes, although techniques for risk adjusting financial outcomes are fairly well developed in rehabilitation, primarily to support Medicare and other prospective payment systems. This article reviews important methodologic issues in risk adjusting rehabilitation outcomes in observational studies of routine clinical practice or for management, such as assessing quality or costs of care. Risk adjusting rehabilitation outcomes is more difficult than risk adjusting other clinical results, such as outcomes of many acute care services. At the outset, characterizing rehabilitation interventions is frequently difficult. Furthermore, outcomes are diverse and depend on myriad factors, including patients' physical and cognitive abilities, underlying medical diseases, sensory and emotional factors, willingness to participate in care, and supportive environments. No risk-adjustment approach can control for every factor affecting outcomes of care. Knowing which risk factors are missing helps guide interpretation of the results and determines how well risk-adjusted outcomes fairly compare providers or treatments.
