Attitudes of cardiac rehabilitation and stroke teams towards integration of stroke survivors into adapted cardiac rehabilitation: A focus group study.

OBJECTIVE: To explore the attitudes and beliefs of cardiac rehabilitation and stroke teams towards adapted cardiac rehabilitation, and the broader topics of exercise, healthy lifestyles and health behaviour change, for people with mild-to-moderate severity stroke in the sub-acute phase of recovery. DESIGN: Qualitative focus group-based study. SETTING: Acute and community national health service trusts. PARTICIPANTS: Stroke and cardiac rehabilitation team members. INTERVENTION: Adapted cardiac rehabilitation. MAIN MEASURES: Focus groups. Thematic analysis was applied to the transcribed data. RESULTS: Overall, 57 health professionals participated in 12 focus groups. Positive impacts for teams and stroke survivors were identified particularly confidence. However, there were negatives, barriers and adaptations identified. In addition, there was a lack of knowledge for cardiac rehabilitation teams in relation to stroke survivors and stroke teams in relation to cardiac rehabilitation, exercise and healthy lifestyles. CONCLUSIONS: Cardiac rehabilitation and stroke staff attitudes to cardiac rehabilitation for stroke survivors showed a range of benefits, negatives, barriers and adaptations needed. Confidence and knowledge of the cardiac rehabilitation and stroke teams needs to be addressed. REGISTRATION: ISRCTN65957980.

Does cardiac rehabilitation for people with stroke in the sub-acute phase of recovery lead to physical behaviour change? Results from compositional analysis of accelerometry-derived data.

OBJECTIVES: Does adapted cardiac rehabilitation (CR) improve the physical behaviours of people with mild-to-moderate stroke in the sub-acute recovery phase using a compositional data analysis (CoDA) approach? DESIGN: Before-after. SETTING: University Hospitals of Leicester, Glenfield Hospital, UK. PARTICIPANTS: 24 individuals completed CR and provided valid physical activity (PA) data (mean (SD) 63.1 (14.6) years, 58% male (14/24)). INTERVENTION: 6-week adapted CR program within 6-months of stroke. MAIN OUTCOME MEASURES: Physical behaviours were assessed using waist-worn accelerometry. Step count, stationary time (ST), light PA (LPA), and moderate-to-vigorous PA (MVPA) were compared pre post CR using conventional analyses and CoDA. Analysed compositions were: Waking day (ST, LPA, MVPA); ST (1-9-minutes, 10-29-minutes, ≥30-minutes bouts); and MVPA (1-4-minutes, 5-9-minutes, ≥10-minutes bouts). RESULTS: Following CR, patients took significantly more steps (mean (SD) 3255 (2864) vs 3908 (3399) steps/day, P=0.004) and engaged in more bouts of MVPA lasting ≥5 and ≥10-minutes (≥5-minutes: mean (SD) 0.7 (1.4) vs 1.2 (1.8) bouts/day, P=0.008). Using CoDA, no changes in waking day or ST compositions occurred. For waking day, 42% (10/24) increased their LPA and MVPA at the expense of ST. For ST, 33% (8/24) increased their short bouts at the expense of medium and long bouts. For MVPA, 13% (3/24) increased their medium and long bouts at the expense of short bouts. CONCLUSION: People with stroke in the sub-acute stage of recovery exhibited low levels of PA. CR appears to be an effective intervention to increase step count but did not alter the overall proportion of time individuals spent being sedentary, or engaging in LPA or in MVPA.

The validity and reliability of the Incremental Shuttle Walk Test and Six-minute Walk Test compared to an Incremental Cycle Test for people who have had a mild-to-moderate stroke.

OBJECTIVE: To determine the construct validity and test re-test reliability of the Six-minute Walk Test (6MWT) and Incremental Shuttle Walk Test (ISWT) in the sub-acute recovery phase following mild-to-moderate severity stroke. PARTICIPANTS: 40 stroke patients (mean age: 68.27 years, SD: 13.48) of median National Institutes of Health Stroke Scale (NIHSS) score 1.2 (range: 0 to 8) within six months of stroke. METHOD: Each participant completed one Incremental Cycle Test (ICT) followed by two ISWT and two 6MWT in a randomised order. Pearson's Correlation Coefficients were used to determine the validity and Bland Altman plots were used to determine the test re-test reliability. RESULTS: The Incremental Cycle Test (ICT) was positively correlated with the ISWT (r=0.59, 95% confidence intervals 0.35 to 0.76, P=0.001) and the 6MWT (0.55, 0.35 to 0.71, P<0.001). The correlation of the ICT with the ISWT and 6MWT was higher for the 17 patients with no residual (ISWT: r=0.79, P<0.001; 6MWT: 0.826, P<0.001) compared to mild-to-moderate neurological impairment (ISWT: r=0.45, P=0.03; 6MWT: r=0.38, P=0.08). Test-retest reliability for both the ISWT and the 6MWT showed that there was some variability between the first and second tests with a better performance on the second test. CONCLUSION: The ISWT and 6MWT have a significant, modest correlation with the ICT for stroke patients in the sub-acute recovery phase. The ISWT and 6MWT are not strongly correlated with ICT (VO2 peak) in a stroke population that is disabled. The test-retest reliability of the ISWT and 6MWT indicated that two tests may be needed to accurately assess an individual's capabilities.
