Inter- and intra-tester reliability of the acute brain injury physiotherapy assessment (ABIPA) in patients with acquired brain injury.

BACKGROUND: The Acute Brain Injury Physiotherapy Assessment (ABIPA) is a new outcome measure with face validity and sensitivity to change in the early stages of neuromotor recovery after acquired brain injury (ABI). Reliability of physiotherapists using the tool has not been established. OBJECTIVE: Determine inter- and intra-tester reliability of physiotherapists using the ABIPA. METHODS: An observational study using video-recorded assessments of patient performance (n = 7) was undertaken with two cohorts of physiotherapists: those receiving training (n = 23) and those provided with guidelines only (n = 7) to administer the ABIPA. RESULTS: Across all physiotherapists (n = 30), inter-tester reliability was excellent (α ≥ 0.9) for total ABIPA score. All individual items, except trunk alignment in supine (α = 0.5), showed excellent or good internal consistency (α ≥ 0.7). For intra-tester reliability, substantial or perfect agreement was achieved for eight items (weighted Kappa Kw ≥ 0.6), moderate agreement for four items (Kw = 0.4-0.6) and three items achieved fair agreement (alignment head supine: Kw = 0.289; alignment trunk supine: Kw = 0.387 and tone left upper limb: Kw = 0.366). CONCLUSION: Physiotherapists are highly consistent using the ABIPA but several items may need revision to improve intra-tester reliability.

Feasibility of a physiotherapist-supervised walking program with telephone coaching to increase physical activity following acquired brain injury.

Background Physical activity has health benefits for adults with acquired brain injury, but it is a challenge to increase physical activity during inpatient rehabilitation. The objectives of this pilot study were to determine whether a physiotherapy-supervised inpatient walking program was feasible and able to improve physical activity and sedentary behaviour in the short and medium term. Methods Adults with acquired brain injury receiving inpatient rehabilitation undertook twice-weekly supervised walks plus behavioural therapy for 4 weeks. Feasibility was measured via recruitment, participation and drop out rates, adverse events and intervention delivery costs. Physical activity and sedentary behaviour were measured with an activPAL. Assessments were conducted at baseline, post-intervention and 3-6 months post-intervention. Results The program was safe to deliver (no adverse events), recruitment rate was 55% (16/29) and the participation rate for eligible individuals was high (14/19, 74%). However, the program had a high drop out rate (7/16, 44%) and physical activity and sedentary behaviour did not significantly change during the 4-week intervention. Costs were AU$427.71/participant. Physical activity and sedentary behaviour did improve 3-6 months after the intervention (vs baseline, on average: +3913 steps per day, 95% CI: 671, 7156). Conclusion This pilot study demonstrated a supervised physiotherapy walking program is safe and feasible to recruit in an inpatient setting. However, drop out during the study was high and behaviour change did not occur. More work is required to boost physical activity during sub-acute rehabilitation for acquired brain injury.

Feasibility of gaming console exercise and its effect on endurance, gait and balance in people with an acquired brain injury.

OBJECTIVE: To determine feasibility of gaming console exercise and its effect on endurance, gait and balance in people following acquired brain injury (ABI). METHOD: Twenty-one people following ABI were recruited to an 8-week randomized cross-over trial where 4 weeks of gaming console exercise in addition to usual therapy and 4 weeks of usual therapy alone were received. Feasibility measures included compliance, session duration and adverse events. Measures included endurance measured using a 6-minute walk test, spatiotemporal gait parameters (GAITRite) and balance using Balance Outcome Measure for Elder Rehabilitation (BOOMER). Motivation was measured using the Change Assessment Questionnaire. RESULTS: Compliance with gaming console exercise was high (99%), the majority of sessions reached duration target (82%) and there were no adverse events. There were small, though non-significant increases in 6-minute walk distance (18 metres, 95% CI = -33 to 69), gait speed (0.11 m s(-1), 95% CI = -0.18 to 0.29) and balance compared to after usual therapy after gaming console exercise. CONCLUSIONS: Gaming console exercise appears feasible in people with ABI. Four weeks of gaming console exercise in addition to usual therapy appears to result in similar improvements in endurance, gait and balance compared to usual therapy alone and may enhance active engagement in therapy.

Physiotherapist observation of head and neck alignment.

OBJECTIVE: To determine the reliability of physiotherapists' visual observation of head and neck alignment. DESIGN: An interrater reliability study with an evaluation of concurrent validity using a gold standard. SETTING: Physiotherapy Research Laboratory, Princess Alexandra Hospital. PARTICIPANTS: Three physiotherapist raters, one male model exhibiting 53 test positions. MAIN OUTCOME MEASURES: Assessment of head and neck alignment required rating the direction of deviation (in each of the three planes of movement), and the magnitude of deviation. RESULTS: All three assessors were correct across all domains of direction and magnitude of deviation for only 10 of the 53 test positions. There was a mean of 2 total errors (out of a possible 12) per position. The more planes of deviation involved in a position, the more total errors there were. Most errors were made in the axial rotation (transverse) plane. Where a lateral flexion (coronal) plane of deviation was involved, there were more total errors; however, this plane itself had the fewest number of errors. Positions with a combination of both lateral flexion and axial rotation deviations were often mistaken for a flexion/extension (sagittal plane) deviation. Fewer errors were recorded for positions of 10-degree deviation compared to 5-degree deviations. CONCLUSIONS: Visual assessment of head and neck alignment by physiotherapists is of questionable validity for identifying deviations in the order of 5 degrees from neutral. For deviations of 10 degrees in a single plane visual, observation is comparable to other clinically available tools.
