Embedded motivational interviewing combined with a smartphone application to increase physical activity in people with sub-acute low back pain: a cluster randomised controlled trial.

BACKGROUND: Moderately vigorous physical activity (PA) may be beneficial for people with sub-acute low back pain (LBP), but may initially be painful for patients and challenging for physical therapists to facilitate. OBJECTIVES: This study investigated motivational interviewing (MI) delivered by physical therapists and a smartphone app for increasing PA in people with LBP. METHODS: A mixed methods cluster randomised controlled trial involving 46 adults with LBP in Melbourne, Australia. Participants attended weekly 30-min physical therapy consultations for 6 weeks. Experimental group physical therapists were taught to embed MI into consultations and patients were provided with a self-directed app. The primary outcome was accelerometer-derived moderately vigorous PA. Secondary outcomes were LBP disability (Oswestry Disability Index), functional capacity (Patient Specific Functional Scale), and self-efficacy (Pain Self-Efficacy Questionnaire). Between-group differences were analysed by ANCOVA post-intervention. RESULTS: There was no statistically significant difference between the experimental group and control group for PA. Between-group differences in LBP disability (MD= 19.4 units, 95% CI: 8.5, 30.3), functional capacity (primary MD= -4.1 units, 95% CI: -6.9, -1.3; average MD= -3.1, 95% CI: -4.9, -1.2) and self-efficacy (MD -11.3 units, 95%CI -20.2, -2.5) favoured the control group with small to moderate effect sizes. There were low levels of overall engagement with the app. CONCLUSION: The embedded MI intervention was no more beneficial than physical therapy alone for PA and was associated with poorer LBP disability, function, and self-efficacy. The effectiveness of embedding MI and a smartphone app into usual care for LBP was not supported.

Promoting positive physical activity behaviours in children undergoing acute cancer treatment: feasibility of the CanMOVE intervention.

BACKGROUND: Supporting children and adolescents with cancer to be physically active can improve medium- and long-term health outcomes. OBJECTIVE: To assess the feasibility of CanMOVE, a 10-week complex, theoretically-informed, behaviour change intervention to promote physical activity for children and adolescents undergoing acute cancer treatment. METHODS: A feasibility study using a single-group, repeated measures, mixed methods design. Participants completed CanMOVE, which included provision of a Fitbit (child/adolescent and carer) and structured support from a physical therapist. Feasibility domains of demand, acceptability, implementation, practicality, limited efficacy, and integration were evaluated. Data sources included service level data, objective assessment of physical activity, physical function, and health-related quality of life; and qualitative data collected via semi-structured interviews with participants and focus groups with staff. RESULTS: Twenty children/adolescents (median age 13yrs, interquartile-range 9-14) with a mix of cancer diagnoses, 20 parents, and 16 clinicians participated. There was high demand with 95% enrolment rate. CanMOVE was acceptable for participants. All feasibility thresholds set for implementation were met. Under practicality, there were no serious adverse events related to the intervention. Limited efficacy data indicated CanMOVE showed positive estimates of effect in influencing child/adolescent physical activity behaviour, physical function, and health-related quality of life. Positive impacts were also seen in parent and staff attitudes towards physical activity promotion. To improve integration into the clinical setting, it was suggested the duration and scope of CanMOVE could be expanded. CONCLUSION: CanMOVE was feasible to implement in a paediatric cancer setting. CanMOVE is appropriate to be tested in a large-scale trial.

Limb salvage in octogenarians with critical limb ischemia after lower extremity bypass surgery.

OBJECTIVES: Peripheral artery disease is a worldwide epidemic that affects millions of patients, especially the elderly. It has a prevalence of 20% in individuals >80 years old. Although peripheral artery disease affects >20% of octogenarians, information about limb salvage rates in this patient population is limited. Therefore, this study aims to understand the impact of bypass surgery on limb salvage in patients aged >80 years with critical limb ischemia. METHODS: We conducted a retrospective analysis by querying the electronic medical records at a single institution from 2016 through 2022 to identify the population of interest and analyzed their outcomes after lower extremity bypass. The primary outcomes were limb salvage and primary patency, with hospital length of stay and 1-year mortality as secondary outcomes. RESULTS: We identified 137 patients who met the inclusion criteria. The lower extremity bypass population was divided into two cohorts: <80 years old (n = 111) with a mean age of 66 or ≥80 years old (n = 26) with a mean age of 84 years. The gender distribution was similar (P = .163). No significant difference was found in the two cohorts when it came to coronary artery disease, chronic kidney disease, or diabetes mellitus. However, when current and former smokers were grouped together, they were significantly more common in the younger cohort when compared with nonsmokers (P = .028). The primary end point of limb salvage was not significantly different between the two cohorts. Hospital length of stay was not significantly different between the two cohorts with 4.13 days vs 4.17 days in the younger vs octogenarian cohorts, respectively (P = .95). The 30-day all-cause readmissions were also not found to be significantly different between the two groups. The primary patency at 1 year was 75% and 77% (P = .16) for the <80-year-old and ≥80-year-old cohorts, respectively. Mortality was low in both cohorts, with two and three for the younger and octogenarian populations, respectively; thus, no analysis was performed. CONCLUSIONS: Our study shows that octogenarians who undergo the same preoperative risk assessment as younger populations have similar outcomes when it comes to primary patency, hospital length of stay, and limb salvage when comorbidities were considered. Further studies need to be done to determine the statistical impact on mortality in this population with a larger cohort.

Benefits and harms of non-surgical and non-pharmacological management of osteoporotic vertebral fractures: A systematic review and meta-analysis.

BACKGROUND: Osteoporotic vertebral fractures affect a large number of older adults OBJECTIVES: Systematically review evidence of the benefits and harms of non-surgical and non-pharmacological management of people with osteoporotic vertebral fractures compared with standard care (control); and evaluate the benefits and harms of non-surgical and non-pharmacological management of people with osteoporotic vertebral fractures compared with an alternative non-pharmacological, non-invasive intervention. DESIGN: Systematic review and meta-analysis of randomized controlled trials. Five electronic databases (CINAHL, EMBASE, MEDLINE, PUBMED, and COCHRANE) were searched. Eligible trials included participants with primary osteoporosis and at least one vertebral fracture diagnosed on radiographs, with treatment that was non-surgical and non-pharmacological involving more than one session. RESULTS: Twenty randomized controlled trials were included with 2083 participants with osteoporotic vertebral fractures. Exercise, bracing, multimodal therapy, electrotherapy, and taping were investigated interventions. Meta-analyses provided low certainty evidence that exercise interventions compared to no exercise were effective in reducing pain in patients with osteoporotic vertebral fractures (mean difference (MD)= 1.01; 95% confidence interval (CI): 0.08, 1.93), and low certainty evidence that rigid bracing intervention compared with no bracing was effective in reducing pain in patients with osteoporotic vertebral fractures (MD= 2.61; 95%CI: 0.95, 4.27). Meta-analyses showed no differences in harms between exercise and no exercise groups. No health-related quality of life or activity improvements were demonstrated for exercise interventions, bracing, electrotherapy, or multimodal interventions. CONCLUSIONS: Exercise and rigid bracing as management for patients with osteoporotic vertebral fractures may have a small benefit for pain without increasing risk of harm.
