RESUMO
OBJECTIVE: To establish the feasibility and effectiveness of a 6-week ballistic strength training protocol in people with stroke. DESIGN: Randomized, controlled, assessor-blinded study. SETTING: Subacute inpatient rehabilitation. PARTICIPANTS: Consecutively admitted inpatients with a primary diagnosis of first-ever stroke with lower limb weakness, functional ambulation category score of ≥3, and ability to walk ≥14 m were screened for eligibility to recruit 30 participants for randomization. INTERVENTIONS: Participants were randomized to standard therapy or ballistic strength training 3 times per week for 6 weeks. MAIN OUTCOME MEASURES: The primary aim was to evaluate feasibility and outcomes included recruitment rate, participant retention and attrition, feasibility of the exercise protocol, therapist burden, and participant safety. Secondary outcomes included measures of mobility, lower limb muscle strength, muscle power, and quality of life. RESULTS: A total of 30 participants (11% of those screened) with mean age of 50 years (SD 18) were randomized. The median number of sessions attended was 15 of 18 and 17 of 18 for the ballistic and control groups, respectively. Earlier than expected discharge to home (n=4) and illness (n=7) were the most common reasons for nonattendance. Participants performed the exercises safely, with no study-related adverse events. There were significant (P<.05) between-group changes favoring the ballistic group for comfortable gait velocity (mean difference [MD] 0.31m/s, 95% confidence interval [CI]: 0.08-0.52), muscle power, as measured by peak jump height (MD 8cm, 95% CI: 3-13), and peak propulsive velocity (MD 64cm/s, 95% CI: 17-112). CONCLUSIONS: Ballistic training was safe and feasible in select ambulant people with stroke. Similar rates of retention and attrition suggest that ballistic training was acceptable to patients. Secondary outcomes provide promising results that warrant further investigation in a larger trial.

INTRODUCTION: Continuing allied health professional (AHP) clinical education is essential to ensure high-quality patient care; however, the effectiveness of current education programs is unclear. This review aimed to determine whether AHP education programs improve the knowledge of AHPs, change their clinical practice behavior, and/or improve patient-related clinical outcome and to identify important components of these programs. METHODS: Four electronic databases were searched. Controlled clinical trials investigating the effectiveness of clinical education programs were included. Education programs were diverse, varying in design, delivery mode, and intensity. Only therapy-specific AHPs were included. Effectiveness was determined by differences in group outcomes in the domains of AHP knowledge, AHP clinical practice behavior, and patient-related clinical outcomes. RESULTS: Forty-four studies were identified, of which 26 included physiotherapists only. Most control groups were waitlist, passive dissemination of information, or usual care, limiting comparisons between programs. Changes in AHP knowledge was investigated in 20 trials, with 13 showing an improvement. Thirty studies investigated changes in AHP clinical practice behavior, with half demonstrating a difference between groups. Seventeen studies investigated a patient-related clinical outcome, with five finding a difference between groups. Where improvements in outcomes were demonstrated, programs tended to incorporate self-selection and cater to the learner's contextual needs. DISCUSSION: AHP knowledge is effectively improved through targeted education programs. To change AHP behavior and patient outcomes, it seems important to incorporate self-selection for the program and consider the learner's individual needs and contexts through mentoring, outreach visits, reflection, and incorporating patient participation in the learning.
