Limited evidence exists regarding care pathways for stroke survivors who do and do not receive poststroke spasticity (PSS) treatment.

Administrative data was used to identify adults who experienced a stroke and sought acute care between 2012 and 2017 in Alberta, Canada. Pathways of stroke care within the health care system were determined among those who initiated PSS treatment (PSS treatment group: outpatient pharmacy dispensation of an anti-spastic medication, focal chemo-denervation injection, or a spasticity tertiary clinic visit) and those who did not (non-PSS treatment group). Time from the stroke event until spasticity treatment initiation, and setting where treatment was initiated were reported. Descriptive statistics were performed.

Health care settings within the pathways of stroke care that the PSS (n = 1,079) and non-PSS (n = 22,922) treatment groups encountered were the emergency department (86 and 84%), acute inpatient care (80 and 69%), inpatient rehabilitation (40 and 12%), and long-term care (19 and 13%), respectively. PSS treatment was initiated a median of 291 (interquartile range 625) days after the stroke event, and most often in the community when patients were residing at home (45%), followed by “other” settings (22%), inpatient rehabilitation (18%), long-term care (11%), and acute inpatient care (4%).

To our knowledge, this is the first population based cohort study describing pathways of care among adults with stroke who subsequently did or did not initiate spasticity treatment. Areas for improvement in care may include strategies for earlier identification and treatment of PSS.

The objective of this study is to determine the physical evaluations and assessment tools used by a group of Canadian healthcare professionals treating adults with spasticity.

A cross-sectional web-based 19-question survey was developed to determine the types of physical evaluations, tone-related impairment measurements, and assessment tools used in the management of adults with spasticity. The survey was distributed to healthcare professionals from the Canadian Advances in Neuro-Orthopedics for Spasticity Congress database.

Eighty study participants (61 physiatrists and 19 other healthcare professionals) completed the survey and were included. Nearly half (46.3%, 37/80) of the participants reported having an inter- or trans-disciplinary team managing individuals with spasticity. Visual observation of movement, available range of motion determination, tone during velocity-dependent passive range of motion looking for a spastic catch, spasticity, and clonus, and evaluation of gait were the most frequently used physical evaluations. The most frequently used spasticity tools were the Modified Ashworth Scale, goniometer, and Goal Attainment Scale. Results were similar in brain- and spinal cord-predominant etiologies. To evaluate goals, qualitative description was used most (37.5%).

Our findings provide a better understanding of the spasticity management landscape in Canada with respect to staffing, physical evaluations, and outcome measurements used in clinical practice. For all etiologies of spasticity, visual observation of patient movement, Modified Ashworth Scale, and qualitative goal outcomes descriptions were most commonly used to guide treatment and optimize outcomes. Understanding the current practice of spasticity assessment will help provide guidance for clinical evaluation and management of spasticity.

Hip flexor spasticity in patients with upper motor neuron syndrome of multiple etiologies has been managed with botulinum neurotoxin injections mainly targeting the “iliopsoas” muscle. A lumbar approach to target psoas major (PM) has been described; however, it has not been incorporated into clinical practice due to perceived risk of injury to surrounding structures. This study will investigate the feasibility and accuracy of ultrasound-guided (UG)-PM injection using a lumbar approach by assessing the intra/extramuscular injectate spread in cadaveric specimens.

In eight lightly embalmed specimens, toluidine blue dye/saline was injected into PM using a UG-posterior lumbar approach. The posterior abdominal wall was exposed, and dye spread and surrounding structures digitized and modeled in 3D. The area and vertebral level of dye spread, distance of dye to the inferior vena cava (IVC), and abdominal aorta (AA) and dye spread to adjacent organs were quantified.

The models enabled visualization of the dye spread in 3D. Mean area of dye spread was 24.4 ± 2.8 cm2; most commonly between L2 and L4 vertebral levels. Mean distance of the dye to AA was 3.2 ± 1.2 cm and to IVC was 1.8 ± 0.4 cm. Dye spread remained intramuscular in all but one specimen. No dye spread occurred to any adjacent organs.

The injection of PM using the UG-posterior lumbar approach was consistent and without spread to surrounding structures. This technique alone or in addition to the anterior approach is expected to have better clinical outcomes in the treatment of hip flexor spasticity. Further clinical studies are required.

Although therapeutic treatments are intended to help alleviate symptoms associated with disease, safety must be carefully considered and monitored to confirm continued positive benefit/risk balance. The objective of MOBILITY was to study the long-term safety of onabotulinumtoxinA for treatment of various therapeutic indications.

A prospective, multicenter, observational, Phase IV Canadian study in patients treated with onabotulinumtoxinA for a therapeutic indication. Dosing was determined by the participating physician. Adverse events (AEs) were recorded throughout the study.

Patients (n = 1372) with adult focal spasticity, blepharospasm, cerebral palsy, cervical dystonia, hemifacial spasm, hyperhidrosis, or “other” diagnoses were enrolled into the safety cohort. Eighty-three patients (6%) reported 209 AEs; 44 AEs in 24 patients (2%) were considered treatment-related AEs. Seventy-two serious AEs were reported by 38 patients (3%); 10 serious AEs in 5 patients (0.4%) were considered treatment related. Most commonly reported treatment-related AEs were muscular weakness (n = 7/44) and dysphagia (n = 6/44).

In patients with follow-up for up to six treatments with onabotulinumtoxinA, treatment-related AEs were reported in <2% of the safety population over the course of nearly 5 years. Our findings from MOBILITY provide further evidence that onabotulinumtoxinA treatment is safe for long-term use across a variety of therapeutic indications.

The objectives were to evaluate the, usability, feasibility of use, satisfaction, and safety of the Syqe Inhaler Exo (Syqe Inhaler), a metered dose, Pharmacokinetics-validated, cannabis inhaler device in a cohort of hospitalized patients that were using medical cannabis under license as a part of their ongoing medical treatment.

Before and after inhaling from the Syqe Inhaler, participants were asked to fill a questionnaire regarding pain reduction on a visual analog scale from 0 to 10 and, if relevant, reduction in chemotherapy-induced nausea and vomiting and/or spasticity. A patient satisfaction questionnaire and a usability questionnaire were filled in following the last use. Prescribed treatment included 4 daily doses of 500 μg tetrahydrocannabinol each delivered from 16 mg cannabis flos per inhalation plus up to an additional four SOS (distress code for more doses of cannabis) doses.

Daily cannabis dose consumed during hospitalization with the Syqe Inhaler was 51 mg (20–96) versus 1,000 mg (660-3,300) consumed prehospitalization. Patients were easily trained and continued to use Syqe Inhaler for the duration of their hospitalization (5 [3–7] days). Pain intensity 30–60 minutes following inhalations was reported to be significantly lower than preinhalation 4 [1–5] versus 7 [2–9]). Participants ranked their satisfaction with Syqe Inhaler as 6 (5–7). Three participants reported mild cough, which resolved spontaneously.

Cannabis inhalation by combustion is not feasible for hospitalized patients. The use of Syqe Inhaler during hospitalization yielded high levels of patients and staff satisfaction with no complications.
