RESUMO
PURPOSE: The aim of this study was to investigate the relationship between corticosteroid dose and degree of physical function decrease in allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients during the early stage of recovery. We further investigated the confounding factors affecting loss of physical function. METHODS: The study included 113 patients who underwent allo-HSCT between July 2007 and April 2012 at Hyogo College of Medicine Hospital in Japan. Physical function was assessed using tests for hand-grip strength, knee-extensor strength, and the 6-min walk test (6MWT). Fatigue was measured using the Piper Fatigue Scale. Total corticosteroid dose, frequency of physical therapy, body weight, and nutritional status were also collected from medical records. RESULTS: Total corticosteroid dose was correlated with decrease of hand-grip and knee-extensors strength (P < 0.01) but was not correlated with 6MWT performance. Results of multivariate analysis confirmed that low physical function was associated not only with high corticosteroid dose but also with low frequency of physical therapy, increase in fatigue, and body weight loss (P < 0.05). Also, hemoglobin levels were associated with 6MWT (P < 0.05). CONCLUSIONS: This study showed the relationship between corticosteroid dose and declines in physical function and also showed other clinical factors affecting loss of physical function among allo-HSCT patients. Our results indicate that the effectiveness of rehabilitation may be influenced by corticosteroid treatment.

Objectives: This study compared the balance function in patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) with their balance function after subsequent training sessions with a Balance Exercise Assist Robot (BEAR). Methods: In this prospective observational study, inpatients who underwent allo-HSCT from human leukocyte antigen-mismatched relatives were enrolled from December 2015 to October 2017. Patients were allowed to leave their clean room after allo-HSCT and underwent balance exercise training using the BEAR. Sessions (20-40 min) were performed 5 days per week and consisted of three games that were performed four times each. A total of 15 sessions were performed by each patient. Patient balance function was assessed before BEAR therapy according to the mini-balance evaluation systems test (mini-BESTest), and patients were divided into two groups (Low and High) based on a 70% cut-off value for the total mini-BESTest score. Patient balance was also assessed after BEAR therapy. Results: Fourteen patients providing written informed consent fulfilled the protocol: six patients in the Low group, and eight patients in the High group. In the Low group, there was a statistically significant difference between pre- and post-evaluations in postural response, which a sub-item of the mini-BESTest. In the High group, there was no significant difference between pre- and post-evaluations in the mini-BESTest. Conclusions: BEAR sessions improve balance function in patients undergoing allo-HSCT.
RESUMO
OBJECTIVES: The Balance Exercise Assist Robot (BEAR) is a boarding-type robot developed to improve users' balance performance. However, the exercise load experienced by users of the BEAR remains unclear. Therefore, this study aimed to identify the exercise load of BEAR users. METHODS: Recruited healthy participants were fitted with an expiratory gas analyzer, and instructed to control the avatar displayed on the computer monitor by shifting their weight on the BEAR. Three types of activity (tennis, skiing, and rodeo) were prepared for the BEAR, and the difficulty of each activity had 40 levels. Each balance exercise for each level lasted for 90 s. The BEAR was administered at levels 1, 5, 10, and then up to 40 in steps of 5 for each activity. The major parameters that were evaluated were oxygen consumption (grossVO2, netVO2), metabolic equivalents (METs), and heart rate (HR). Two-way analysis of variance with Tukey's post hoc test was applied to each level of each activity. RESULTS: Fourteen healthy participants were recruited. For the rodeo activity, netVO2 and MET values were significantly higher than those for tennis and skiing at level 20 (tennis vs. skiing vs. rodeo: netVO2 114.0±59.7 vs. 160.6±71.1 vs. 205.6±82.9, METs 1.47±0.22 vs. 1.72±0.37 vs. 1.90±0.29) and higher. Furthermore, comparisons within activity types showed that at level 40, netVO2 and MET were significantly higher than for level 1. The exercise intensity was found to increase along with the exercise level for all three activity types, with rodeo being the highest at 2.74 METs. CONCLUSIONS: The current findings show that the BEAR can be used for balance practice without generating excessive cardiopulmonary stress.
RESUMO
BACKGROUND: Functional electrical stimulation (FES) for patients with stroke and foot drop is an alternative to ankle foot orthoses. Characteristics of FES responders and nonresponders have not been clarified. OBJECTIVES: (1) To investigate the effects of treatment with FES on patients with stroke and foot drop and (2) to determine which factors may relate to responders and nonresponders. DESIGN: Multicenter, nonrandomized, prospective study. SETTING: Multicenter clinical trial. PARTICIPANTS: Participants included those who experienced foot drop resulting from stroke, were older than 20 years, and could provide consent to participate; they were enrolled from hospitals between January 2013 and September 2015 and performed rehabilitation with FES. METHODS: Stroke Impairment Assessment Set Foot-Pat Test (SIAS-FP), Fugl-Meyer Assessment for Lower Extremity (FMA-LE), Modified Ashworth scale (MAS) for ankle joint dorsiflexion and plantar flexion muscles, range of motion (ROM) for ankle joint, 10-m walking test (10mWT), Timed Up & Go test (TUG), and 6-minute walking test (6MWT) were evaluated pre- and postintervention. Age, gender, type of stroke, onset times of stroke, paretic side, Brunnstrom stage of the lower extremity (Br. stage-LE), Functional Independence Measure (FIM), Functional Ambulation Category (FAC), poststroke months, number of interventions, total hours of interventions, and whether a brace was used were extracted from patients' medical records and collected on the physiological examination day. MAIN OUTCOME MEASUREMENTS: The authors examined 10mWT and age, gender, type of stroke, onset times of stroke, paretic side, Br. stage-LE, FIM, FAC, poststroke months, number of interventions, total hours of interventions, whether a brace was used, SIAS-FP, FMA-LE, MAS, ROM, TUG, and 6MWT before intervention. Participants were divided into nonresponders and responders with a change in 10mWT of <0.1 and ≥0.1 m/s, respectively. Single and multiple regression analyses were used for data analysis. Additionally, the changes between groups were compared. RESULTS: Fifty-eight responders and 43 nonresponders were enrolled. The between-group differences, compared for changes between pre- and postintervention, were significant in terms of changes in SIAS-FP (P = .02), 10mWT (P < .001), 10-m gait steps (P < .001), TUG (P = .04), and 6MWT (P = .006). In the adjusted regression model, gender (odds ratio [OR], 3.92; 95% confidence interval [CI], 1.426-12.25; P = .007), number of interventions (OR, 1.028; 95% CI, 1.003-1.070; P = .03), and active ankle joint dorsiflexion ROM (OR, 1.047; 95% CI, 1.014-1.088; P = .005) remained significant. CONCLUSION: The factors related to 10mWT showing changes beyond the minimal clinically important difference were found to be patient gender, number of interventions, and active ankle joint dorsiflexion ROM before intervention. When patients with stroke who have greater active ankle joint ROM, and are female, use FES positively, they may benefit more from using FES. LEVEL OF EVIDENCE: II.
