Does Task-Specific Training Improve Upper Limb Performance in Daily Life Poststroke?
Neurorehabilitation and Neural Repair, 2016Co-Authors: Kimberly J. Waddell, Rebecca L. Birkenmeier, Michael J. Strube, Ryan R. Bailey, Joseph W. Klaesner, Alexander W. Dromerick, Catherine E LangAbstract:Background. A common assumption is that changes in upper limb (UL) capacity, or what an individual is capable of doing, translates to improved UL performance in daily life, or what an individual actually does. This assumption should be explicitly tested for individuals with UL paresis poststroke. Objective. To examine changes in UL performance after an intensive, individualized, progressive, Task-Specific UL intervention for individuals at least 6 months poststroke. Methods. Secondary analysis on 78 individuals with UL paresis who participated in a phase II, single-blind, randomized parallel dose-response trial. Participants were enrolled in a Task-Specific intervention for 8 weeks. Participants were randomized into 1 of 4 treatment groups with each group completing different amounts of UL movement practice. UL performance was assessed with bilateral, wrist-worn accelerometers once a week for 24 hours throughout the duration of the study. The 6 accelerometer variables were tested for change and the influe...

Validity of body-worn sensor acceleration metrics to index upper extremity function in hemiparetic stroke.
Journal of Neurologic Physical Therapy, 2015Co-Authors: M. A. Urbin, Ryan R. Bailey, Catherine E LangAbstract:BACKGROUND AND PURPOSE: Accelerometers have been used to capture real-world use of the paretic upper extremity in people with stroke. It may be possible to characterize different aspects of the recorded acceleration to gain insight about movement capabilities during Task-Specific behavior. These measures may be of value for guiding rehabilitation. We undertook a study to identify the acceleration characteristics that have a stable association with upper extremity function and sensitivity to within-participant fluctuations in function over multiple sessions of Task-Specific Training. METHODS: Twenty-seven adults 6 months or more poststroke with upper extremity paresis participated. Signals from wrist-worn accelerometers were sampled at 30 Hz during 7 sessions of Task-Specific Training. Paretic upper extremity function was evaluated with the Action Research Arm Test. We used Spearman correlations to examine within-session associations between acceleration metrics and Action Research Arm Test performance. A mixed model was used to determine which metrics were sensitive to within-participant fluctuations in upper extremity function across the 7 Training sessions. RESULTS: Upper extremity function correlated with bilateral acceleration variability and use ratio during 5 and 6 sessions, respectively. Time accelerating between 76% and 100% of peak acceleration correlated with function in 6 sessions. Variability of the paretic upper extremity acceleration and the ratio of acceleration variability between upper extremities were associated with function during all 7 sessions. Variability in both the acceleration of the paretic upper extremity, and acceleration of the paretic and nonparetic extremities combined were sensitive to within-participant fluctuations in function across Training sessions. DISCUSSION AND CONCLUSIONS: Multiple features of the acceleration profile track with upper extremity function within and across sessions of Task-Specific Training. It may be possible to monitor these features with accelerometers to index upper extremity function outside of clinical settings.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, http://links.lww.com/JNPT/A91).

Acceleration metrics are responsive to change in upper extremity function of stroke survivors.
Archives of Physical Medicine and Rehabilitation, 2014Co-Authors: M. A. Urbin, Kimberly J. Waddell, Catherine E LangAbstract:Abstract Objectives To (1) determine whether acceleration metrics derived from monitoring outside of treatment are responsive to change in upper extremity (UE) function; and secondarily to (2) compare metric values during Task-Specific Training and while in the free-living environment, and (3) establish metric associations with an in-clinic measure of movement capabilities. Design Before-after observational study. Setting Inpatient hospital (primary purpose); outpatient hospital (secondary purpose). Participants Individuals (n=8) with UE hemiparesis Intervention The inpatient sample was evaluated for UE movement capabilities and monitored with wrist-worn accelerometers for 22 hours outside of treatment before and after multiple sessions of Task-Specific Training. The outpatient sample was evaluated for UE movement capabilities and monitored during a single session of Task-Specific Training and the subsequent 22 hours outside clinical settings. Main Outcome Measures Action Research Arm Test (ARAT) and acceleration metrics quantified from accelerometer recordings. Results Five metrics improved in the inpatient sample, along with UE function as measured on the ARAT: use ratio, magnitude ratio, variation ratio, median paretic UE acceleration magnitude, and paretic UE acceleration variability. Metric values were greater during Task-Specific Training than in the free-living environment, and each metric was strongly associated with ARAT score. Conclusions Multiple metrics that characterize different aspects of UE movement are responsive to change in function. Metric values are different during Training than in the free-living environment, providing further evidence that what the paretic UE does in the clinic may not generalize to what it does in everyday life.

Feasibility of high-repetition, Task-Specific Training for individuals with upper-extremity paresis
American Journal of Occupational Therapy, 2014Co-Authors: Kimberly J. Waddell, Rebecca L. Birkenmeier, T. George Hornby, Jennifer Moore, Catherine E LangAbstract:: OBJECTIVE. We investigated the feasibility of delivering an individualized, progressive, high-repetition upper-extremity (UE) Task-Specific Training protocol for people with stroke in the inpatient rehabilitation setting. METHOD. Fifteen patients with UE paresis participated in this study. Task-Specific UE Training was scheduled for 60 min/day, 4 days/wk, during occupational therapy for the duration of a participant's inpatient stay. During each session, participants were challenged to complete ≥300 repetitions of various tasks. RESULTS. Participants averaged 289 repetitions/session, spending 47 of 60 min in active Training. Participants improved on impairment and activity level outcome measures. CONCLUSION. People with stroke in an inpatient setting can achieve hundreds of repetitions of Task-Specific Training in 1-hr sessions. As expected, all participants improved on functional outcome measures. Future studies are needed to determine whether this high-repetition Training program results in better outcomes than current UE interventions.

On use of task independent Training data in tandem feature extraction
2004 IEEE International Conference on Acoustics Speech and Signal Processing, 2004Co-Authors: S. Sivadas, H. HermanskAbstract:The problem we address in this paper is, whether the feature extraction module trained on large amounts of task independent data, can improve the performance of stochastic models? We show that when there is only a small amount of task specific Training data available, tandem features trained on task independent data give considerable improvement over perceptual linear prediction (PLP) cepstral features in hidden Markov model (HMM) based speech recognition systems.

Effectiveness of Modified Constraint-Induced Movement Therapy in Children With Unilateral Spastic Cerebral Palsy: A Randomized Controlled Trial
Neurorehabilitation and Neural Repair, 2010Co-Authors: Pauline Aarts, Peter H. Jongerius, Yvonne A. Geerdink, Jacques Van Limbeek, Alexander C. H. GeurtsAbstract:BACKGROUND: In children with unilateral spastic cerebral palsy (CP), there is only limited evidence for the effectiveness of modified constraint-induced movement therapy (mCIMT). OBJECTIVE: To investigate whether 6 weeks of mCIMT followed by 2 weeks of bimanual Task-Specific Training (mCIMT-BiT) in children with unilateral spastic CP improves the spontaneous use of the affected limb in both qualitative and quantitative terms more than usual care (UC) of the same duration. METHODS: Children with unilateral spastic CP with Manual Ability Classification System (MACS) scores I, II, or III and aged 2.5 to 8 years were recruited and randomly allocated to either the mCIMT-BiT group (three 3-hour sessions per week: 6 weeks of mCIMT, followed by 2 weeks of Task-Specific Training in goal-directed bimanual play and self-care activities) or to 1.5 hours of more general physical or occupational weekly plus encouragement to use the affected hand for the UC group. Primary outcome measures were the Assisting Hand Assessment and the ABILHAND-Kids. Secondary outcomes were the Melbourne Assessment of Unilateral Upper Limb Function, the Canadian Occupational Performance Measure, and the Goal Attainment Scale. RESULTS: Twenty-eight children were allocated to mCIMT-BiT and 24 to UC. Except for the Melbourne, all primary and secondary outcome measures demonstrated significant improvements in the mCIMT-BiT group. CONCLUSION: mCIMT followed by Task-Specific Training of goal-directed bimanual play and self-care activities is an effective intervention to improve the spontaneous use of the more affected upper limb in children with relatively good baseline upper extremity function.
