Posterior fall-recovery training applied to individuals with chronic stroke: A single-group intervention study
The skill of posterior stepping in response to a perturbation can be improved with practice in those with chronic stroke, we were not able to identify consistent underlying kinematic mechanisms behind this adaptation.

The international normalised ratio predicts perioperative complications in revision total hip arthroplasty.
CONCLUSIONS: Our analysis illustrates a direct relationship between specific preoperative INR levels and poor outcomes following rTHA, including increased LOS, transfusion requirements and infection. Therefore, current INR guideline targets may need to be re-examined when optimising patients for revision arthroplasty. PMID: 33269618 [PubMed - as supplied by publisher]

Relationship between bone strength index of the hemiparetic tibial diaphysis and muscle strength in people with chronic stroke: influence of muscle contraction type and speed
ConclusionsConcentric muscle power was more predictive of %SSD in p-SSI at the tibial diaphysis than other contraction types and may be an important target for intervention to promote bone health in people with chronic stroke.

Risk of Incident Atrial Fibrillation With Zoledronic Acid Versus Denosumab: A Propensity Score –Matched Cohort Study
ABSTRACTZoledronic acid (ZA) is an effective agent in osteoporosis and malignancy ‐related bone disease but may be associated with increased risk of atrial fibrillation (AF), although current studies disagree on this risk. To examine the risk of incident AF among patients receiving ZA compared with denosumab in the first year of treatment, we performed a new‐user, active comp arator cohort study including privately insured Americans between January 1, 2010, and June 30, 2019. Individuals aged ≥50 years without known arrhythmia or advanced kidney disease who initiated ZA were 1:1 propensity score (PS)‐matched to i...

When the Nervous System Turns Skeletal Muscles into Bones: How to Solve the Conundrum of Neurogenic Heterotopic Ossification
AbstractPurpose of ReviewNeurogenic heterotopic ossification (NHO) is the abnormal formation of extra-skeletal bones in periarticular muscles after damage to the central nervous system (CNS) such as spinal cord injury (SCI), traumatic brain injury (TBI), stroke, or cerebral anoxia. The purpose of this review is to summarize recent developments in the understanding of NHO pathophysiology and pathogenesis. Recent animal models of NHO and recent findings investigating the communication between CNS injury, tissue inflammation, and upcoming NHO therapeutics are discussed.Recent FindingsAnimal models of NHO following TBI or SCI ...

Walking test procedures influence speed measurements in individuals with chronic stroke
Walking test procedures influence walking speed and concurrent validity between measurements. Waking test procedures should be as similar as possible with normative data or between repeated measurements to optimize validity.

Incidence and risk factors associated with postoperative stroke in the elderly patients undergoing hip fracture surgery
Stroke is one of the rare but devastating complications after hip fracture in the elderly. By far, there is still scarce data on postoperative stroke in elderly patients with hip fractures.

Application of Novel Graphite Flex Sensors in Closed-Loop Angle Feedback on a Soft Robotic Glove for Stroke Rehabilitation
Conclusions This work has presented a novel integration and implementation of graphite-based flex sensors with a soft robotic glove for stroke rehabilitation. The relationship between the signal voltage and the MCP joint angle varies greatly with anatomical differences between each individual, and with sensor placement. However, based on the experimental results, a linear mapping calibration algorithm for the graphite-based flex sensors was implemented, which also complements its robustness for the potential application on stroke rehabilitation. The effectiveness of the calibration algorithm is also thus demonstrated via...

Trends in Comorbidities and Complications Among Patients Undergoing Inpatient Spine Surgery
Study Design. Retrospective database study. Objective. We sought to identify trends in demographics, comorbidities, and postoperative complications among patients undergoing ACDF and PLF. Summary of Background Data. As demand for anterior cervical discectomy and fusion (ACDF) and posterior lumbar fusion (PLF) surgery continues to increase, it is important to understand changes in the healthcare system and patient populations undergoing these procedures. Methods. We identified 220,520 ACDF and 151,547 PLF surgeries (2006–2016; Premier Healthcare database). Annual proportions or medians were calculated for patie...

Mortality and Morbidity of Surgical Management of Geriatric Ankle Fractures.
DISCUSSION: After controlling for comorbidities (ie, the ASA class), no increased risk is observed for the 30-day mortality or complication rate between geriatric ankle fracture in the 65 to 79 years old and the 80 to 99 years old age groups. LEVEL OF EVIDENCE: Prognostic level III, retrospective study. PMID: 32769723 [PubMed - in process]

Effects of Diabetes Mellitus on Functional Outcomes and Complications After Torsional Ankle Fracture.
CONCLUSIONS: Diabetes was associated with more complications and secondary operations. However, functional outcomes including pain and dysfunction were not markedly affected by these clinical outcomes, potentially due to diminished sensory function and less baseline physical activity among diabetic patients. LEVEL OF EVIDENCE: Prognostic level III. PMID: 32769721 [PubMed - in process]

Cardiovascular safety of denosumab across multiple indications: a systematic review and meta ‐analysis of randomized trials
AbstractThe cardiovascular safety of denosumab has not yet been evaluated in a systematic review. This systematic review and meta ‐analysis sought to quantify the number of randomized controlled trials (RCTs) of denosumab (against comparators) reporting cardiovascular adverse events (CAEs) and examine the balance of CAEs between treatment arms. MEDLINE, Embase andclinicaltrials.gov were searched from inception to 26th October 2019 for RCTs of denosumab versus comparators for any indication. Included trials were randomized, enrolled ≥100 participants and reported bone‐related outcomes. Primary outcome for analysis was...
