Association of Preoperative Depression Score With Outcomes of Transfibular Total Ankle Arthroplasty.

Favorable short-term results of transfibular total ankle arthroplasty have been reported in several studies; however, the factors affecting these results have not been elucidated. This study aimed to determine whether preoperative depression affects the outcome of transfibular total ankle arthroplasty and whether depression changes with surgery. Scores from the Japanese Society of Surgery of the Foot Ankle/Hindfoot scale (JSSF scale), Self-Administered Foot Evaluation Questionnaire (SAFE-Q), Hospital Anxiety and Depression Scale (HADS), and Timed Up & Go test (TUG) were collected preoperatively, at 6 months, and at 1 year postoperatively from 20 patients. Eighteen patients were diagnosed with osteoarthritis and 2 patients with rheumatoid arthritis. The mean age of the patients was 75 years. Patients were divided into 2 groups: those with preoperative HADS depression scores above the median (higher depression score group) and below the median (lower depression score group), and intergroup comparisons were made. No significant differences were observed in the JSSF and TUG scores between the groups, both preoperatively and postoperatively. Meanwhile, the SAFE-Q pain subscale score was significantly lower in the higher depression score group than in the lower depression score group (median, 59 vs 90) 1 year postoperatively. There were no differences in the other SAFE-Q subscale scores between the groups. The results suggested that depressive tendencies did not affect postoperative functional results using objective assessment measures but had a negative impact on pain in subjective assessment measures.

Differential activation of psoas major and rectus femoris during active straight leg raise to end range.

The purpose of this study was to investigate the activation of the hip flexor and abdominal muscles during an active straight leg raise (ASLR) to end range of hip flexion. Data were recorded from nine healthy men. Fine-wire electromyography (EMG) electrodes were inserted into psoas major (PM), and surface electrodes were placed over rectus femoris (RF), rectus abdominis, obliquus externus abdominis (OE), and obliquus internus abdominis/transversus abdominis (OI/TrA). EMG and kinematic data were obtained during concentric, hold (at end range) and eccentric phases of an ASLR. Concentric and eccentric movements were divided into three phases (early, mid, and late). Onsets of EMG relative to the onset of the ALSR movement and EMG amplitudes in each phase were compared between muscles. Onsets of the PM (-33 ± 245 ms) and RF (-3 ± 119 ms) EMG prior to leg elevation were significantly earlier than those of the OE and OI/TrA. PM EMG showed highest activation in the late concentric, hold, early eccentric phase, and was significantly higher than RF EMG. OI/TrA EMG was significantly greater in mid and late concentric, hold, and early eccentric phase than other phases. During the ASLR, unlike RF, PM EMG continues to increase towards the end range of hip flexion. Activation of OI/TrA muscle may be involved in control trunk and pelvic movement.

Effectiveness of Early Rehabilitation for Vertebral Compression Fractures: A Retrospective Cohort Study.

BACKGROUND AND PURPOSE: Most patients become physically inactive after vertebral compression fracture and thus need help for early mobilization. This study sought to investigate the effect of early rehabilitation on activities of daily living in patients following acute vertebral compression fracture. METHODS: We conducted this retrospective cohort study with a hospital-based database created by the Japan Medical Data Center and comprising data from a Diagnosis Procedure Combination survey from more than 100 acute care hospitals across Japan. Data of consecutive inpatients hospitalized because of thoracic and/or lumbar compression fractures from 2014 to 2018 were extracted. We compared characteristics and outcomes between patients who underwent early rehabilitation (early rehabilitation group) and those who did not undergo rehabilitation (no rehabilitation group). The primary outcome measure was Barthel Index improvement. RESULTS: After applying exclusion criteria, a total of 8493 eligible patients with acute vertebral compression fracture were included in this study. The unadjusted data showed significantly greater Barthel Index improvement (72.5% vs 60.3, P < .001) and a higher rate of discharge to home (82.9% vs 77.4, P < .001) among patients in the early rehabilitation group compared with the no rehabilitation group. After adjustment by propensity score analysis, significant between-group differences were found. CONCLUSION: Early rehabilitation could possibly be a feasible alternative for maintenance of the Barthel Index in patients with acute vertebral compression fracture.

Effectiveness of Early Versus Delayed Physical Rehabilitation on In-Hospital Mortality in Interstitial Pneumonia: A Retrospective Cohort Study.

INTRODUCTION: Although early rehabilitation for acute inpatients is widely recommended, the effectiveness of early physical rehabilitation for interstitial pneumonia in the acute setting remains unclear. OBJECTIVE: To investigate the impact of early rehabilitation on mortality in patients with interstitial pneumonia in the acute setting. DESIGN: Retrospective cohort study used a hospital-based database created by the Japan Medical Data Center. SETTING: Over 100 acute-care hospitals across Japan. PARTICIPANTS: Inpatients hospitalized due to interstitial pneumonia from 2014 to 2018. INTERVENTIONS: Early rehabilitation provided by physical therapists and/or occupational therapists within 2 day of admission. MAIN OUTCOME MEASURES: Thirty- and 90-day in-hospital mortality. RESULTS: Among the included inpatients, 847 (50%) underwent early rehabilitation. Mortality was significantly lower in the early rehabilitation group compared with the delayed rehabilitation group (30-day mortality: 6.8% vs 12.1%, 90-day mortality: 13.0% vs 19.8%). The differences were significant after propensity score adjustment using inverse probability weighting (30-day mortality: 7.6% vs 11.0%, 90-day mortality: 14.3% vs 18.0%). CONCLUSION: Early rehabilitation was associated with decreased mortality in hospitalized patients with interstitial pneumonia.

Effectiveness of self-exercise on elderly patients after hip fracture : A retrospective cohort study.

The purpose of this study was to clarify the impact of self-exercise for elderly patients in an acute hospital after hip fracture. This retrospective observational study used data from the Japan Rehabilitation Database spanning 2005-2015. This study identified in-hospital hip fracture patients admitted to an acute hospital. After applying exclusion criteria, 375 patients were eligible. The primary outcome was motor Functional Independence Measure (FIM) efficiency. Of the patients with hip fracture, 39% performed self-exercises. Patients who performed self-exercise had significantly higher motor FIM efficiency than those who did not (1.22 vs. 0.79 ; P ?0.01). Multivariable regression analysis showed that motor FIM efficiency was significantly and positively correlated with self-exercise (coefficient, 0.25 ; 95% confidence interval, 0.13 to 0.43 ; P ?0.01). The data suggest that self-exercise is associated with good rehabilitation outcomes in hip fracture patients. J. Med. Invest. 66 : 178-181, February, 2019.

Hip and trunk muscles activity during nordic hamstring exercise.

The nordic hamstring exercise (NHE) is a dynamic lengthening hamstring exercise that requires trunk and hip muscles activation. Thigh muscles activation, specifically hamstring/quadriceps contractions has been previously examined during NHE. Trunk and hip muscles activity have not been enough studied. The aim of this study was to analyze of hip and trunk muscles activity during NHE. Surface electromyography (EMG) and kinematic data were collected during NHE. Ten healthy men with the age range of 21-36 years performed two sets of two repetitions with downward and upward motions each of NHE. EMG activity of fifteen trunk and hip muscles and knee kinematic data were collected. Muscle activity levels were calculated through repeated measure analysis of variance in downward and upward motions, through Paired t-test between downward and upward motions and gluteus maximus to erector spine activity ratio (Gmax/ES ratio) using Pearson correlation analyses were evaluated. Semitendinosus and biceps femoris muscles activity levels were the greatest in both motions and back extensors and internal oblique muscles activity were greater than other muscles (P<0.05). The decreased Gmax/ES ratio was significantly related to peak knee extension angle in downward (r=0.687) and upward motions (r=0.753) (P<0.05). These findings indicate the importance of synergistic muscles and trunk muscles coactivation in eccentric and concentric hamstrings contractions. It could be important for early assessment of subjects with hamstring injury risk.

Rehabilitation Characteristics in High-Performance Hospitals after Acute Stroke.

BACKGROUND: Rehabilitation characteristics in high-performance hospitals after acute stroke are not clarified. This retrospective observational study aimed to clarify the characteristics of high-performance hospitals in acute stroke rehabilitation. METHODS: Patients with stroke discharged from participating acute hospitals were extracted from the Japan Rehabilitation Database for the period 2006-2015. We found 6855 patients from 14 acute hospitals who were eligible for analysis in this study after applying exclusion criteria. We divided facilities into high-performance hospitals and low-performance hospitals using the median of the Functional Independent Measure efficiency for each hospital. We compared rehabilitation characteristics between high- and low-performance hospitals. RESULTS: High-performance hospitals had significantly shorter length of stay. More patients were discharged to home in the high-performance hospitals compared with low-performance hospitals. Patients in high-performance hospitals received greater amounts of physical, occupational, and speech therapy. Patients in high-performance hospitals engaged in more self-exercise, weekend exercise, and exercise in wards. There was more participation of board-certified physiatrists and social workers in high-performance hospitals. CONCLUSIONS: Our data suggested that amount, timing, and type of rehabilitation, and participation of multidisciplinary staff are essential for high performance in acute stroke rehabilitation.

Effectiveness of weekend physical rehabilitation for functional recovery in geriatric patients with hip fracture.

AIM: To test the hypothesis that the functional outcome of hip fracture patients who receive weekend rehabilitation is better than that of similar patients who undergo non-weekend rehabilitation. METHODS: The present retrospective observational study used data from the Japan Rehabilitation Database spanning 2005-2015. We identified in-hospital hip fracture patients admitted to acute hospitals. After applying exclusion criteria, 469 patients were eligible. The primary outcome was motor Functional Independence Measure (FIM) efficiency. RESULTS: Of the patients with hip fracture, 68.0% received weekend rehabilitation. The patients who received weekend rehabilitation had significantly higher scores in motor FIM efficiency (mean 1.08 vs 0.73, P < 0.001), FIM efficiency (mean 1.12 vs 0.79, P = 0.001) and shorter length of stay (mean 32 vs 54, P < 0.001) than the patients without weekend rehabilitation. Multivariate linear regression analysis identified the weekend rehabilitation as a significant factor in motor FIM efficiency (coefficient 0.237, 95% confidence interval 0.074-0.400, P = 0.004), FIM efficiency (coefficient 0.235, 95% confidence interval 0.079-0.391, P = 0.003) and length of stay (coefficient -9.649, 95% confidence interval -18.194 to -1.104, P = 0.027). CONCLUSIONS: The present cohort analysis showed that weekend rehabilitation for hip fracture patients can lead to functional recovery and reduce the length of stay.

Effectiveness of preoperative physical therapy for older patients with hip fracture.

AIM: To clarify the effectiveness of preoperative physical therapy for older patients after hip fracture in an acute care hospital. METHODS: In the present retrospective observational study, data from the Japan Rehabilitation Database were analyzed for patients admitted to an acute care hospital with hip fracture between 2005 and 2015. In this study, all eligible patients received surgery within 10 days of admission. Propensity score analysis was used to compare outcomes between patients who underwent preoperative rehabilitation and those who did not. The primary outcome was motor Functional Independence Measure (FIM) gain. RESULTS: Of the 681 patients eligible after applying exclusion criteria, 50% underwent preoperative rehabilitation after hip fracture. Both before and after adjustment by inverse probability weighting, motor FIM gain was significantly higher in patients who underwent preoperative rehabilitation (motor FIM gain 31.1 ± 18.2 before weighting, 31.1 ± 18.2 after weighting) than in those who did not (motor FIM gain 24.6 ± 18.1 before weighting, P < 0.01; 26.2 ± 17.6 after weighting, P < 0.02). In addition, motor FIM effectiveness and motor FIM at discharge were significantly higher among patients who underwent preoperative rehabilitation. CONCLUSIONS: Our data suggest that preoperative rehabilitation after hip fracture is associated with better rehabilitation outcomes than no preoperative rehabilitation.

The effect of dynamic stretching on hamstrings flexibility with respect to the spino-pelvic rhythm.

OBJECTIVES: To ascertain the dynamic stretch effects of flexibility of the hamstrings on lumbar spine and pelvic kinematics. BACKGROUND: Tight hamstrings are positively correlated with low back pain. However, it is unclear how flexibility of the hamstrings affects spino-pelvic rhythm. METHODS: Twelve healthy men participated in the study. The straight leg raising (SLR) angle, finger floor distance (FFD), and spino-pelvic rhythm was measured before and after the 6-week stretching protocol. The forward bending task was divided into 4 phases. The paired t-test was used to determine significant differences before and after the FFD, SLR angle, lumbar motion, and pelvic motion, and spino-pelvic rhythm in each phase (p<0.05). RESULTS: After 6 weeks of stretching, significant improvements were seen in the FFD with maximum forward bending and in the SLR angle. Total pelvic rotation was also significantly increased in contrast to total lumbar flexion. A decreased spino-pelvic ratio was seen in the final phase. CONCLUSION: Dynamic stretching could change the spino-pelvic rhythm to a pelvis-dominant motion, indicating that flexible hamstrings are important for preventing low back pain.

Spino-pelvic-rhythm with forward trunk bending in normal subjects without low back pain.

A strong correlation between low back pain and tight hamstrings has been reported. However, the effect of tight hamstrings on spinal biomechanics remains unclear. The purpose of the study was to investigate spino-pelvic-rhythm during forward bending of the trunk and to clarify the rhythm features with regard to hamstrings tightness. Eighteen healthy male adults with no history of low back pain volunteered to participate. First, we measured the finger-to-floor distance (FFD) in the upright position and set this parameter to 100 %. Using a spinal mouse, spinal alignment was measured in the following four positions: (1) upright posture­100 % FFD; (2) forward bending­50 % FFD; (3) forward bending­25 % FFD; and (4) forward bending­0 % FFD (fingers in contact with the floor). Changes of the angle of the thoracic and lumbar spine as well as the pelvis were calculated. As an indicator of tight hamstrings, we measured straight leg raising (SLR) angle. From positions 1­2 (phase I), the entire spino-pelvic angle moved in 104°. During this phase, the lumbar spine mainly moved. In the second phase (positions 2­3), it moved in 16°. Interestingly, all but 2 subjects showed a negative angle in the thoracic motion, meaning that the thoracic spine extended 4° during trunk flexion, thus exhibiting paradoxical motion. During this phase, lumbopelvic rhythm showed 2 patterns. In 7 subjects, pelvic motion was greater than lumbar motion, while the remaining subjects showed the opposite. In subjects without tight hamstrings, 83 % showed a pelvis-dominant pattern. Only 7 subjects were capable of position 4. During this phase, only slight motion was noted in the spine, and the majority of the motion occurred in the pelvis. Lumbar and pelvic motion correlated negatively in all phases. SLR angle and pelvic motion correlated strongly during phase III, indicating dominant pelvic movement in flexible subjects. The lumbo-pelvic-rhythm comprises 2 patterns­lumbar dominant and pelvis dominant. In flexible subjects, pelvis movement was dominant. In conclusion, improving tight hamstrings may reduce lumbar loading thereby reducing low back pain.

Jack-knife stretching promotes flexibility of tight hamstrings after 4 weeks: a pilot study.

Tight hamstrings are reported to be one of the causes of low back pain. However, there have been few reports on effective stretching procedures for the tight hamstrings. The so-called jack-knife stretch, an active-static type of stretching, can efficiently increase the flexibility of tight hamstrings. To evaluate hamstring tightness before and after the 4-week stretching protocol in healthy volunteer adults and patients aged under 18 years with low back pain. For understanding the hamstrings tightness, we measured two parameters including (1) finger to floor distance (FFD) and (2) pelvis forward inclination angle (PFIA). Eight healthy adult volunteers who had no lumbar or hip problems participated in this study (mean age: 26.8 years). All lacked flexibility and their FFD were positive before the experiment. Subjects performed 2 sets of the jack-knife stretch every day for 4 weeks. One set consisted of 5 repetitions, each held for 5 s. Before and during the 4-week experiment, the FFD and PFIA of toe-touching tests were measured weekly. For 17 of the sports players aged under 18, only FFD was measured. In adult volunteers, FFD was 14.1 ± 6.1 cm before the experiment and decreased to -8.1 ± 3.7 cm by the end of week 4, indicating a gain in flexibility of 22.2 cm. PFIA was 50.6 ± 8.2 before the experiment and 83.8 ± 5.8 degrees after. Before and after the experiment, the differences were significant (p < 0.05). For those aged under 18, FFD was 8.1 ± 8.0 and -9.6 ± 6.8, before and after the stretching, respectively. This difference was significant (p < 0.05). The jack-knife stretch is a useful active-static stretching technique to efficiently increase flexibility of tight hamstrings.
