Relationship of serial muscle ultrasound of rectus femoris and ambulatory recovery in patients with acute incomplete spinal cord injury: A prospective observational study.

CONTEXT/OBJECTIVE: To investigate the change in serial muscle ultrasound of rectus femoris of patients with incomplete spinal cord injury (SCI) performed within 2 months after SCI during acute rehabilitation, and the relationship with functional outcomes at 1 year post-injury. DESIGN: Prospective observational study. SETTING: Inpatient multi-speciality tertiary rehabilitation center in Singapore. PARTICIPANTS: Fifty-four patients with incomplete SCI, defined as American Spinal Injury Association Impairment Scale B-D, with SCI above L2, were recruited from March 2020 to June 2021. Serial muscle ultrasound of the rectus femoris thickness and echo intensity were obtained at 1 week post-injury and after 2 months via standardized protocols. OUTCOME MEASURES: Functional Independence Measure (FIM) motor score, Lower Extremity Motor Score (LEMS), Spinal Cord Independence Measure III (SCIM III) indoor mobility component and Walking Index for Spinal Cord Injury II (WISCI II) were assessed in the first week post-admission and at 1 year. RESULTS: There was a significant positive correlation between change in rectus femoris muscle thickness over 2 months and FIM motor score (P < 0.001), LEMS (P < 0.001), SCIM III indoor mobility component (P < 0.001) and WISCI II (P < 0.001) at 1 year. For the change in echo intensity over 2 months, there was a significantly negative correlation with FIM motor score (P = 0.002), LEMS (P = 0.002), SCIM III indoor mobility component (P = 0.001) and WISCI II (P = 0.001) at 1 year. CONCLUSION: The findings suggest that ultrasonographic serial assessment of rectus femoris muscle thickness and echo intensity during rehabilitation may be useful for determining the long-term functional outcomes in patients with incomplete SCI.

Return to Work in Breast Cancer Patients following an Interdisciplinary Rehabilitation Program in a Community-Based Cancer Rehabilitation Center: A Pilot Study.

Despite curative treatment and discharge from acute hospital settings, breast cancer patients often have cancer- and treatment-related morbidity which impairs them from returning to work. Hence, the role of community-based return to work rehabilitation programs is important to help these patients transition back to work. This was a retrospective cohort study involving patients with breast cancer conducted at a community-based cancer rehabilitation center. Patients were involved in an interdisciplinary vocational rehabilitation program involving physiatrists, occupational therapists, physiotherapists and social workers. We recruited 63 patients for this study cohort, with 46 (73.0%) patients ≤ 60 years old. After undergoing the rehabilitation program, there were 37 (58.7%) participants who successfully returned to work. These participants returned to work at either within 6 months (27.0%), 12 months (29.7%) or 24 months (43.2%) after enrollment into the program, with a majority enrolling in white collar jobs. Multivariate regression analysis revealed that significant negative factors for return to work were advanced stage of cancer (p = 0.004), along with clinically significant fatigue, measured on the Brief Fatigue Inventory (p < 0.001). However, perceived work ability (p = 0.020) was found to be a positive factor.

Acute Ultrasonographic Changes in Lower Extremity Muscle Structure after Motor Complete Spinal Cord Injury.

Background: There is a lack of studies examining ultrasonographic muscle changes in patients with acute spinal cord injury (SCI). Methods: We recruited adults with motor complete acute SCI and performed longitudinal ultrasound measurements. The primary outcome measures were rectus femoris and medial gastrocnemius thickness and echo intensity. Results: This study recruited 20 patients, with a mean time to the first ultrasound measurement of 17.2 ± 2.14 days, with the second measurement done 4 weeks after the first measurement. We found that there was a mean decrease in the rectus femoris muscle thickness of 18.7% (P = 0.027), as well as a mean increase in the rectus femoris echo intensity of 13.0 a.u. (P = 0.009), although no significant differences were found for the medial gastrocnemius. Conclusion: This study demonstrates decreased thickness and increased echo intensity in the rectus femoris but not in the medial gastrocnemius in patients with motor complete SCI.

Assessment of Health-Related Quality of Life and Distress in an Asian Community-Based Cancer Rehabilitation Program.

Cancer survivors have reduced health-related quality of life (HRQOL) and high levels of distress during and after active treatment, due to physical, psychological, and social problems. Understanding the prevalence and associations of HRQOL and distress in a patient population in the community is important when designing rehabilitation programs. This was a cross-sectional observational study conducted at a community-based cancer rehabilitation center, with the aim of investigating the prevalence and associations of HRQOL and distress in cancer patients. There were 304 patients who were recruited. We found low levels of HRQOL and high levels of distress in patients, with a mean FACT-G7 total score of 11.68, and a mean distress thermometer score of 3.51. In the multivariate regression model, significant factors for low HRQOL were metastatic disease (p = 0.025) and Malay ethnicity (p < 0.001). Regression analyses also found that significant distress was associated with family health issues (p = 0.003), depression (p = 0.001), worry (p = 0.005), breathing (p = 0.007), getting around (p = 0.012) and indigestion (p = 0.039). A high prevalence of impaired HRQOL and distress was reported in cancer survivors even in a community rehabilitation setting. The physical and psychosocial well-being of cancer survivors should be monitored and managed as part of community-based cancer rehabilitation.

Ultrasound Assessment of Changes in Muscle Architecture of the Brachialis Muscle After Stroke-A Prospective Study.

Objective: To investigate changes in ultrasound-derived muscle architecture parameters of the brachialis and correlations in patients with subacute stroke. Design: Prospective longitudinal observational study. Setting: Tertiary inpatient rehabilitation center. Participants: Fifty adult patients (N=50) who were recruited within the first month poststroke. The patients had a mean age of 57.2±12.3 years and 68.0% were male. The majority of patients had significant upper limb weakness with a low mean Motricity Index of 18.5±24.7 and median elbow flexor strength of grade 0. Intervention: Not applicable. Main Outcome Measures: Ultrasound of the intact and hemiparetic brachialis was performed at 3-time intervals: within 1 month of stroke onset and at 1 and 6 months after first assessment. Clinical variables captured included upper limb motor power and elbow flexor spasticity. Results: Compared to the intact brachialis, there was reduced muscle thickness (1.93 cm vs 2.07 cm, 1.86 cm vs 2.08 cm, 1.85 cm vs 2.05 cm; P=.022) and increased echo intensity (63.3 arbitrary units [AU] vs 56.8 AU, 69.4 AU vs 56.6 AU, 77.4 AU vs 58.2 AU; P<.001) in the hemiparetic brachialis at all assessment intervals (baseline, 1 month, 6 months). Reduction in muscle mass was greater in older patients, with the correlation coefficient ranging from -0.30 (P=.03) at baseline to -0.50 (P<.001) at 6 months. Presence of elbow flexor spasticity at 1-month assessment interval was associated with lower muscle mass reduction (1.93 cm vs 1.74 cm; P=.017), lower echo intensity (65.1 AU vs 75.1 AU; P=.023), and longer fascicle lengths (12.92 cm vs 9.83 cm; P=.002). Conclusions: Changes including decreased muscle thickness and increased echo intensity of the hemiparetic brachialis were noted over time. Elbow flexor spasticity at 1-month assessment interval appears to mitigate against these changes.

Long-Term Outcomes of Patients with Primary Brain Tumors after Acute Rehabilitation: A Retrospective Analyses of Factors.

Although primary brain tumors are relatively rare, they cause significant morbidity and mortality due to the high rates of neurological impairment. The purpose of this study was to examine the physical and functional outcomes of patients with primary brain tumors who had undergone inpatient rehabilitation. This was a retrospective study which recruited 163 patients who had been admitted for inpatient rehabilitation. Rehabilitation outcomes, including the Functional Independence Measure (FIM) and Glasgow Outcome Scale (GOS), were recorded up to 1 year post-discharge. The majority of patients (79.1%) had low-grade (WHO Class I-II) tumors, 35 (21.5%) were diagnosed with GBM and 52 (31.9%) had recurrent brain tumors. Rehabilitation outcomes were sustained, with 125 (76.7%) and 113 (69.3%) patients having a GOS of ≥4 at 6 months and 1 year after discharge, respectively. A GOS of ≥4 at 1 year was negatively associated with high-grade tumors (p < 0.001) and radiotherapy (p = 0.028), and positively associated with a higher discharge FIM motor score (p < 0.001) and the presence of a caregiver after discharge (p = 0.034). Our study demonstrates significant positive functional benefits from 4 weeks of inpatient neuro-oncological rehabilitation for patients with primary brain tumors, as well as the importance of supportive care from caregivers.

Ultrasound Measurements of Rectus Femoris and Locomotor Outcomes in Patients with Spinal Cord Injury.

Patients with incomplete spinal cord injury have decreased mobility, and many do not recover walking ability. The purpose of this study was to investigate rectus femoris muscle thickness and echo intensity on ultrasound and functional outcomes in these patients. This was a prospective cohort study in an inpatient rehabilitation center, which recruited 40 consecutive patients with incomplete spinal cord injury. The patients underwent an ultrasound assessment at 6 weeks post-injury. Ultrasound measurements were performed using B-mode ultrasound scanning and standardized protocols. Functional outcomes on discharge, including Lower Extremity Muscle Score (LEMS), Functional Independence Measure (FIM), and Walking Index for Spinal Cord Injury II (WISCI II), were measured. Rectus femoris muscle thickness was significantly correlated with discharge LEMS (Spearman's rho = 0.448; p = 0.004), FIM motor subscale (Spearman's rho = 0.595; p < 0.001), FIM walk subscale (Spearman's rho = 0.621; p < 0.001) and WISCI II (Spearman's rho = 0.531; p < 0.001). The rectus femoris echo intensity was also significantly correlated with discharge LEMS (Spearman's rho = −0.345; p = 0.029), FIM motor subscale (Spearman's rho = −0.413; p = 0.008), FIM walk subscale (Spearman's rho = −0.352; p = 0.026), and WISCI II (Spearman's rho = −0.355; p = 0.025). We report that a relationship exists between rectus femoris muscle ultrasonographic characteristics and muscle function and ambulatory outcomes after inpatient rehabilitation. Ultrasound muscle measurements are potentially useful in assessing muscle wasting and function in patients with spinal cord injury.

Identification of Secondary Biomechanical Abnormalities in the Lower Limb Joints after Chronic Transtibial Amputation: A Proof-of-Concept Study Using SPM1D Analysis.

SPM is a statistical method of analysis of time-varying human movement gait signal, depending on the random field theory (RFT). MovementRx is our inhouse-developed decision-support system that depends on SPM1D Python implementation of the SPM (spm1d.org). We present the potential application of MovementRx in the prediction of increased joint forces with the possibility to predispose to osteoarthritis in a sample of post-surgical Transtibial Amputation (TTA) patients who were ambulant in the community. We captured the three-dimensional movement profile of 12 males with TTA and studied them using MovementRx, employing the SPM1D Python library to quantify the deviation(s) they have from our corresponding reference data, using "Hotelling 2" and "T test 2" statistics for the 3D movement vectors of the 3 main lower limb joints (hip, knee, and ankle) and their nine respective components (3 joints × 3 dimensions), respectively. MovementRx results visually demonstrated a clear distinction in the biomechanical recordings between TTA patients and a reference set of normal people (ABILITY data project), and variability within the TTA patients' group enabled identification of those with an increased risk of developing osteoarthritis in the future. We conclude that MovementRx is a potential tool to detect increased specific joint forces with the ability to identify TTA survivors who may be at risk for osteoarthritis.

Changes in muscle architecture on ultrasound in patients early after stroke.

BACKGROUND: Early muscle changes are believed to occur in patients with stroke. However, there are insufficient data on the changes in muscle mass and architecture of these patients. OBJECTIVES: This study investigates differences in ultrasound-derived muscle architecture parameters of the hemiplegic upper and lower limbs in patients with subacute stroke. METHODS: This is a prospective observational study, which recruited 40 adult patients who had experienced a first ever unilateral stroke (ischemic or hemorrhagic), with a duration of < 1 month post stroke. The brachialis, vastus lateralis and medial gastrocnemius on both the hemiplegic and normal side were evaluated via ultrasound. We recorded clinical variables including Motricity Index, Modified Ashworth Scale (MAS) and Functional Independence Measure (FIM)-walk. RESULTS: We found reduced mean muscle thickness (p < 0.001) and increased echo intensity (p < 0.001) in the brachialis muscle, increased echo intensity (p = 0.002) in the vastus lateralis muscle, and reduced muscle thickness (p < 0.001) with increased echo intensity (p < 0.001) in the medial gastrocnemius muscle compared to the normal side. There were no significant correlations between ultrasound findings and Motricity Index. CONCLUSIONS: We report changes in ultrasound-derived muscle architecture in the hemiplegic limbs of patients with subacute stroke, with consistent findings of decreased muscle mass and increased echo intensity.

Prevalence and associations of axillary web syndrome in Asian women after breast cancer surgery undergoing a community-based cancer rehabilitation program.

BACKGROUND: Patients who have breast cancer surgery are at risk of axillary web syndrome (AWS), an under-recognized postsurgical complication which can result in shoulder morbidity and functional impairment. Emerging studies have indicated that AWS may persist beyond the first few months after surgery, although few studies have assessed the prevalence and association of AWS beyond a year after diagnosis. Therefore, the aim of this study was to investigate the prevalence and associations for AWS in post-operative breast cancer patients up to 3 years after surgery. METHODS: This cross sectional observational study was conducted at a community-based cancer rehabilitation center. Patients were evaluated for the presence of AWS via physical examination. Disease-related data was obtained from clinical review and medical records. Descriptive statistics were utilized to illustrate patient demographics and clinical characteristics. Logistic regression analyses were used to determine associations of AWS. RESULTS: There were 111 Asian women who were recruited, who had undergone breast surgery and were referred to a national outpatient rehabilitation center. The prevalence of AWS in this population was 28.9%. In the multivariate regression model, significant factors were age < 50 years (OR = 3.51; 95% CI = 1.12-11.0; p = 0.031) and ALND (OR = 6.54; 95% CI = 1.36-31.3; p = 0.019). There was reduced shoulder flexion ROM (p < 0.001) in patients with AWS compared to patients without AWS. CONCLUSIONS: A high prevalence of AWS was reported in breast cancer survivors even at 3 years after breast surgery. Our findings highlight the need to identify breast cancer survivors with AWS even in the survivorship phase, and develop strategies to raise awareness and minimize functional impairment in these patients.

Hospital readmission in stroke survivors one year versus three years after discharge from inpatient rehabilitation: Prevalence and associations in an Asian cohort.

OBJECTIVE: To examine the prevalence and risk factors for readmission after inpatient rehabilitation in stroke survivors, in a developed multi-ethnic Southeast Asian country. METHODS: A retrospective cohort study of 1,235 stroke survivors who completed inpatient rehabilitation in a tertiary rehabilitation centre. RESULTS: A total of 296 (24.0%) patients with stroke were readmitted within the first year, and 87 (7.0%) patients were readmitted 1-3 years after stroke. Significant risk factors for readmission of patients in the first year post-stroke were older age (p = 0.027), lower admission Functional Independence Measure (FIM) motor (p = 0.001) and cognition scores (p = 0.025), a Charlson Comorbidity Index (CCI) ≥1 (p < 0.001) and the presence of at least 1 medical complication during initial hospitalization (p < 0.001), while FIM gain was found to be protective (p < 0.001). Looking at readmission after 1 year post-stroke, a CCI≥1 (p < 0.001) and the presence of medical complications during initial hospitalization (p < 0.001) were risk factors for readmission, while FIM gain (p = 0.001) was protective. Common causes for readmission include recurrent stroke and falls. CONCLUSION: There is a high readmission rate in stroke survivors, even after the first year post-stroke. Interventions, such as fall risk assessments, vaccinations, meticulous catheter care, intensified secondary risk factors interventions and continued post-discharge rehabilitation, may hold promise for reducing readmission rates.

Morel-Lavallée Lesion of the knee after low-energy impact in a healthy non-athlete.

BACKGROUND AND OBJECTIVE: Morel-Lavallée Lesion (MLL) of the knee is an uncommon cause of knee swelling usually due to high-energy impact or in patients on anticoagulation. MLL of the knee due to low-energy non-athletic associated trauma in patients without antithrombotic therapy is rare. Early diagnosis can be achieved using point-of-care ultrasound. CASE REPORT: A 60-year-old female who was previously well was referred to our center for a persistently swollen left knee 2 months after a fall while on a flight of stairs. A point-of-care ultrasound identified a possible MLL of the knee. This was subsequently confirmed on magnetic resonance imaging (MRI). The lesion resolved with ultrasound-guided therapeutic aspiration. CONCLUSION: MLL of the knee should be a differential diagnosis of traumatic knee swelling, even in low-energy trauma and in patients without bleeding diatheses. Ultrasound is a readily available and rapid modality that can aid both in the diagnosis and management of such lesions.

Prevalence and Risk Factors of Adhesive Capsulitis in Asian Breast Cancer Patients Undergoing an Outpatient Community Cancer Rehabilitation Program.

OBJECTIVES: To investigate the prevalence and risk factors for adhesive capsulitis in postoperative breast cancer patients up to 5 years after surgery who were attending an outpatient community cancer rehabilitation program, and to determine whether any significant relationship exists between arm lymphedema and adhesive capsulitis. DESIGN: Cross-sectional observational study. SETTING: National cancer rehabilitation center. PARTICIPANTS: Asian women (N=135) who underwent breast surgery and were referred for an outpatient community cancer rehabilitation program. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Presence of adhesive capsulitis, lymphedema. RESULTS: The prevalence of adhesive capsulitis and lymphedema in this population was 22.2% and 33.3%, respectively. A history of mastectomy (odds ratio [OR], 3.93; 95% confidence interval [CI], 1.23-12.63; P=.021), mastectomy with reconstruction (OR, 2.72; 95% CI, 1.27-30.54; P=.024), and lymphedema (OR, 7.92; 95% CI, 2.73-22.95; P<.001) were found to be significantly associated with adhesive capsulitis on multivariate analysis. CONCLUSIONS: Adhesive capsulitis and lymphedema are common in breast cancer survivors. The design of cancer rehabilitation programs for breast cancer survivors should include surveillance and management of adhesive capsulitis, especially in the presence of lymphedema.
