Although there is a great deal of success in rehabilitative robotics applied to patient recovery post stroke, most of the research to date has dealt with providing physical assistance. However, new rehabilitation studies support the theory that not all therapy need be hands-on. We describe a new area, called socially assistive robotics, that focuses on non-contact patient/user assistance. We demonstrate the approach with an implemented and tested post-stroke recovery robot and discuss itsdoi:10.1186/1743-0003-4-5 pmid:17309795 pmcid:PMC1821334 fatcat:eo6d5pvkwrgixl7dmijwuw56mu

Results: We describe a pilot study involving an autonomous assistive mobile robot that aids stroke patient rehabilitation by providing monitoring, encouragement, and reminders. The robot navigates autonomously, monitors the patient's arm activity, and helps the patient remember to follow a rehabilitation program. We also show preliminary results from a follow-up study that focused on the role of robot physical embodiment in a rehabilitation context. Conclusion: We outline and discuss future experimental designs and factors toward the development of effective socially assistive post-stroke rehabilitation robots.

Background-Upper extremity use in daily life is a critical ingredient of continued functional recovery after cerebral stroke. However, time-evolutions of use-dependent motion quality are poorly understood due to limitations of existing measurement tools. Objective-Proof-of-concept study to determine if spectral analyses explain the variability of known temporal kinematic movement quality (ie, movement duration, number of peaks, jerk) for uncontrolled reach-to-grasp tasks. Methods-Tendoi:10.1177/1545968313505911 pmid:24213957 pmcid:PMC3900236 fatcat:6dgodper5zc5tihek6s7n7oidu

Temporal and spectral measures were extracted for each gesture. The effects of performance condition on outcome measures were determined using 2-way, within subject, hand (nonparetic vs paretic) × object (present vs absent) analysis of variance. Regression analyses determined if spectral measures explained the variability of the temporal measures. Results-There were main effects of hand on all 3 temporal measures and main effects of object on movement duration and peaks. For the paretic limb, spectral measures explain 41.2% and 51.1% of the variability in movement duration and peaks, respectively. For the nonparetic limb, spectral measures explain 40.1%, 42.5%, and 27.8% of the variability of movement duration, peaks, and jerk, respectively. Conclusions-Spectral measures explain the variability of motion efficiency and control in individuals with stroke. Signal power from 1.0 to 2.0 Hz is sensitive to changes in hand and object. Analyzing the evolution of this measure in ambient environments may provide as yet uncharted information useful for evaluating long-term recovery.
There is considerable evidence that after a stroke, ipsilesional deficits increase as contralesional impairment increases. However, it is unclear whether this relationship differs based on the side of stroke. Here, we tested the hypothesis that the ipsilesional hand motor capacity co-varies with contralesional hand impairment only in individuals with left hemisphere damage. Forty-two pre-morbidly right-handed chronic stroke survivors (left hemisphere damage, LHD = 21) with mild-to-moderatedoi:10.1101/635136 fatcat:qqtuchfdw5btrk27o34z4vslgm

We used univariate co-efficient of determination (R2) and multiple linear regression to assess the relationship between motor capacity of ipsilesional and contralesional hands. Contralesional UEFM, and dWMFT were found to be significant predictors of ipsilesional hand motor capacity (p < 0.0001 for both). Importantly, the relationship between contralesional and ipsilesional hands was significantly modified by side of stroke (model adjusted R2 = 0.26 and 0.42, respectively, p < 0.01). For individuals with LHD, contralesional impairment explained 42% and contralesional hand motor capacity explained 65% of the variance in ipsilesional hand motor capacity. However, this relationship was not statistically significant for individuals with right hemisphere damage (RHD, unadjusted R2 < 1% for UEFM and 9% for dWMFT, p > 0.05). In chronic stroke survivors with mild-to-moderate impairment, our findings demonstrate that the relationship between contralesional and ipsilesional motor deficits depends on the side of stroke. Specifically, deficits co-vary between the limbs of stroke survivors with left hemisphere damage but not right hemisphere damage.

Background-Intensive task-oriented training such as constraint-induced movement therapy (CIMT) is thought to engage motor learning and decision-making processes, including anticipatory action planning. Objective-To identify the effects of CIMT on anticipatory hand posture selection and movement time for task-specific reach-to-grasp performance. Methods-Subacute and chronic poststroke participants were recruited into CIMT (n = 10) or non-CIMT (n = 10) groups. Arm and hand functions were assesseddoi:10.1177/1545968312437938 pmid:22434022 pmcid:PMC6015502 fatcat:enmijmueobb6hfrpusrkmmvwny

The reach-to-grasp tasks included power and precision grasping in 2 conditions achieved optimally with either a pronated (low difficulty) or supinated (high difficulty) hand posture. Outcome measures included success rate, frequency of optimal strategy selection, and movement time. Results-Between-group comparisons revealed a significant treatment effect for WMFT and MAL scores. The CIMT group showed larger gains in success rate, optimal posture selection (precision grasp only), and faster movement times for the supinated conditions. Conclusion-Together, a faster movement time and greater frequency of optimal hand posture selection in the more difficult task condition highlights a set of novel findings. These results provide evidence for training-induced improvements in upper-extremity function that support neurobehavioral recovery more than compensation. Although these findings are preliminary in view of the small sample size, the authors suggest that they may be useful to design and power larger-scale studies to further the understanding of the fundamental mechanisms induced by taskoriented training interventions in neurorehabilitation.
