Implementation of a municipality-based rehabilitation program for patients with neuritis vestibularis: lessons learned and derived snowball effects.

BACKGROUND: Patients with dizziness are severely affected in their daily life. The dizziness may be caused by vestibular neuritis and this condition may be severe and result in hospitalization. Qualified municipal rehabilitation services are warranted for these patients after edischarge from the hospital. However, very few specialized municipal initiatives in Denmark are targeting this patient group. METHODS: This paper reports on the development of a clinically applicable municipality-based vestibular neuritis rehabilitation program and evaluates the acceptability of this initiative. RESULTS: The study recognized the need for a rehabilitation program after hospital discharge. However, the program was not evaluated as acceptable for multiple reasons. The exercise program was applicable and feasible but was experienced as a limitation for the practitioner, when addressing other balance issues was needed. It proved challenging to inform both the administrative staff and the clinicians about the new rehabilitation service to allow for sufficient implementation. CONCLUSION: Although the rehabilitation program was not considered an unequivocal success, there were several derived valuable snowball effects of the program. This paper advocates that focus should not only lie on the success of a single program, but also explore the derived benefits for patients and organizations, as well as the practice-oriented knowledge these programs generate.

"Study protocol for the ≥65 years NOrthern jutland Cohort of Fall risk Assessment with Objective measurements (the NOCfao study)".

BACKGROUND: Accidental falls are common among community-dwellers, probably due to the level of physical activity and impaired postural stability. Today, fall risk prediction tools' discriminative validity are only moderate. In order to increase the accuracy, multiple variables such as highly validated objective field measurements of physical activity and impaired postural stability should be adressed in order to predict falls. The main aim of this paper is to describe the ≥65 years NOrthern jutland Cohort of Fall risk Assessment with Objective measurements (NOCfao) investigating the association between physical activity and impaired postural stability and the risk of fall episodes among community-dwelling older adults. METHODS: The study consists of a baseline session where the participants are asked to respond to three questionnaires, perform physical tests (i.e., measuring strength in the upper and lower extremities, balance, and walking speed), participate in an assessment of pain sensitivity, and to wear an ankle mounted pedometer for measuring physical activity for 5 days. Subsequently, the fall incidences and the circumstances surrounding the falls during the previous 1 to 2 months will be recorded throughout a one-year follow-up period. DISCUSSION: This study will add to the present-day understanding of the association between physical activity and impaired postural stability and the risk of fall episodes among community-dwelling older adults. These data will provide valid and reliable information on the relationship between these variables and their significance for community-dwelling older adults.

The Use of Cognitive Cues for Anticipatory Strategies in a Dynamic Postural Control Task - Validation of a Novel Approach to Dual-Task Testing.

INTRODUCTION: Dual-task testing is relevant in the assessment of postural control. A combination of a primary (motor) and a secondary (distracting cognitive) tasks is most often used. It remains a challenge however, to standardize and monitor the cognitive task. In this study a new dual-task testing approach with a facilitating, rather than distracting, cognitive component was evaluated. METHODS: Thirty-one community-dwelling elderly and fifteen young people were tested with respect to their ability to use anticipatory postural control strategies. The motor task consisted of twenty-five repetitive tasks in which the participants needed to exceed their limit of stability in order to touch one out of eight lights. The participants performed three tests. In two of the tests the color cues of the lights allowed the participants to utilize cognitive strategies to plan their next movement and improve their performance time. RESULTS: The young performed the baseline motor task test in an average of 29 seconds, while the average time for the elderly was 44 seconds. When comparing the performance time with a leading cue to the time with no cue, the young group improved their performance time significantly better than the elderly did: young: 17% (5), elderly: 5% (8); p<0.001. Similar differences were seen with a more complicated leading cue: young: 12% (5), elderly: 4% (9); p<0.01. The reliability of the test showed moderate to substantial agreement (ICC = 0.74), with a small learning effect between two sessions. CONCLUSION: The dual-task test was sensitive enough to discriminate between elderly and young people. It revealed that the elderly did not utilize cognitive cues for their anticipatory postural control strategies as well as the young were able to. The test procedure was feasible and comprehensible for the participants, and it may be relevant to standardize a similar test for an alternative dual-task approach in the clinical setting.
