Frontloading Home Physical Therapy Visits for Patients With Heart Failure: A Multi-center Randomized Controlled Trial.

Frontloading home care visits has been found to be effective in the nursing profession but has not been investigated in physical therapy (PT) practice. This study aimed to examine the impact of frontloading home PT visits on function in persons with heart failure (HF). This was a prospective multi-center randomized controlled trial with blinded raters. A total of 82 ambulatory patients with a primary diagnosis of HF discharged from an acute care facility to home care participated in the study. Subjects were randomly allocated to an experimental frontloaded group (FLG) or control group (CG) for 4 weeks. FLG visit frequencies were five sessions per week for 2 weeks, and three sessions per week for 2 weeks. The CG received two sessions per week for 4 weeks. Functional measures including the 2-minute step test (2MST), 2-minute walk test (2MWT), gait speed (GS), Timed Up and Go (TUG), and 30-second chair rise test (30-CRT) were collected at the onset of care, at the end of 2 weeks and 4 weeks. The groups were statistically similar at baseline for all measures. All subjects significantly improved scores in all functional measures over time, within-subject main effect (p < .01). Significant between-subject effects were noted for 30-CRT (p = .04). Interaction effects were noted for GS (p = .03) and TUG test (p = .02). This is the first study to report meaningful improvements in function in individuals with HF. Significant treatment effect differences between the FLG and CG were found for GS, TUG, and 30-CRT. Future studies should examine the use of a standardized intervention to validate the effectiveness of frontloading home visits on quality of life and readmission rates.

Perturbation-Induced Stepping Post-stroke: A Pilot Study Demonstrating Altered Strategies of Both Legs.

Introduction: Asymmetrical sensorimotor function after stroke creates unique challenges for bipedal tasks such as walking or perturbation-induced reactive stepping. Preference for initiating steps with the less-involved (preferred) leg after a perturbation has been reported with limited information on the stepping response of the more-involved (non-preferred) leg. Understanding the capacity of both legs to respond to a perturbation would enhance the design of future treatment approaches. This pilot study investigated the difference in perturbation-induced stepping between legs in stroke participant and non-impaired controls. We hypothesized that stepping performance will be different between groups as well as between legs for post-stroke participants. Methods: Thirty-six participants (20 persons post-stroke, 16 age matched controls) were given an anterior perturbation from three stance positions: symmetrical (SS), preferred asymmetrical (PAS-70% body weight on the preferred leg), and non-preferred asymmetrical (N-PAS-70% body weight on the non-preferred leg). Kinematic and kinetic data were collected to measure anticipatory postural adjustment (APA), characteristics of the first step (onset, length, height, duration), number of steps, and velocity of the body at heel strike. Group differences were tested using the Mann-Whitney U-test and differences between legs tested using the Wilcoxon signed-rank test with an alpha level of 0.05. Results: Stepping with the more-involved leg increased from 11.5% of trials in SS and N-PAS up to 46% in PAS stance position for participants post-stroke. Post-stroke participants had an earlier APA and always took more steps than controls to regain balance. However, differences between post-stroke and control participants were mainly found when stance position was modified. Compare to controls, steps with the preferred leg (N-PAS) were earlier and shorter (in time and length), whereas steps with the non-preferred leg (PAS) were also shorter but took longer. For post-stroke participants, step duration was longer and utilized more steps when stepping with the more-involved leg compared to the less-involved leg. Conclusions: Stepping with the more-involved leg can be facilitated by unweighting the leg. The differences between groups, and legs in post-stroke participants illustrate the simultaneous bipedal role (support and stepping) both legs have in reactive stepping and should be considered for reactive balance training.

Instrumented Test of Sensory Integration for Balance: A Validation Study.

BACKGROUND AND PURPOSE: Abnormal postural sway is associated with an increase in risk of falls but is difficult for clinicians to accurately quantify without access to laboratory equipment. Instrumenting clinical outcome measures using body-worn movement monitors is a low-cost alternative. This is the first study to compare the modified Clinical Test of Sensory Integration for Balance (i-mCTSIB) to the laboratory test of the Sensory Organization Test (SOT) with dynamic posturography in a group of participants with Parkinson's disease (PD) and subtle balance limitations. The purpose of this study was to (1) determine the concurrent validity of the i-mCTSIB with the SOT (6 and 4 conditions) and (2) compare the i-mCTSIB and the SOT to differentiate between individuals with and without recent falls within the previous 6 months. METHODS: This cross-sectional study examined 26 participants with idiopathic PD who had a Motor Unified Parkinson's Disease Rating Scale score of 32.7 (13.5) out of 108. RESULTS: The composite and conditions 1 and 4 of the i-mCTSIB and SOT scores were significantly correlated: composite scores r = -0.64 (P ≤ .001), C1 r = -0.43 (P = .03), C3 r = -0.60 (P ≤ .01), and C4 r = -0.54 (P ≤ .001). A significant difference was observed in mean i-mCTSIB composite scores between fallers and nonfallers (P = .04). In contrast, the SOT composite was not significantly different between fallers and nonfallers (P = 0.31). DISCUSSION: The results suggest that the i-mCTSIB may be a valid and clinically meaningful measure of sensory organization in persons with PD, even those with mild postural instability as measured by the median Hoehn and Yahr score (2.0). Future research should evaluate predictive validity of the i-mCTSIB for prospective falls. CONCLUSION: The instrumented mCTSIB with portable, body-worn movement allows clinicians to quantify abnormal postural sway without the ceiling effects of clinical balance testing or the expense and importability of force plate technology in the SOT. Instrumenting mCTSIB may also distinguish between fallers and nonfallers.

Applying motor-control theory to physical therapy practice: a case report.

PURPOSE: This case report describes the application of an integrated, systems-based theory of motor control to physical therapy practice.Client Description: The patient was a 5-year-old boy with spastic hemiplegic cerebral palsy who was entering kindergarten. Parent concerns related to the child's safety in playground activities such as playing on the slide. INTERVENTIONS: Motor-control theory, including factors related to the task, the environment, and the individual, was used to guide and direct physical therapy management related to the patient goal of safely and effectively climbing the ladder to the playground slide.Patient Outcomes: When the child entered kindergarten, he was able to safely ascend the ladder to the playground slide, using a modified movement pattern, when distractions were minimized. However, attentional issues continued to affect task execution when other children were present. IMPLICATIONS: This case report demonstrates a means by which current knowledge and theory can be integrated into clinical practice. FUTURE DIRECTIONS: Applying motor-control theory to this case led to the development of clinical questions for future research.
