Pain, Function and Unmet Health-care Needs in Hospitalized Victims 3 Years After the Terror Attacks in Norway July 22nd 2011

Research Posters Naoki Tanaka (Institute of Medical Science and Welfare, University of Tsukuba), Hiroki Watanabe, Takeshige kanamori, Hiroaki Yano, Hisako Yanagi Research Objectives: To compare the effects of gait training using a footpad-type locomotion interface (GTLI) with those of gait training using a body-weight support treadmill (BWST) in chronic post-stroke patients. Design: Non-randomized crossover pilot study. Setting: Outpatient department. Participants: Eleven ambulatory chronic post-stroke patients. Interventions: In group A (n Z 7), the patients underwent training using GTLI followed by that using BWST, whereas in group B (n Z 4), the patients underwent training using BWST followed by that using GTLI. All the participants underwent twelve 20-min sessions of both GTLI and BWST over 4 weeks. Main Outcome Measure(s): The outcome measures were maximum gait speed, timed up and go test (TUG), and isometric muscle strengths of both hip and knee flexion and extension. These measures were evaluated at pre-training, post-training, and 1 month post-training. There was a non-training period of at least 8 weeks between each training session. Results: There were no differences in the patient characteristics between the 2 groups. In comparison with using BWST, the muscle strength in paretic hip extension and knee flexion significantly improved using GTLI. However, in comparison with using BWST, the maximum gait speed and TUG did not significantly improve using GTLI. Conclusions: These results suggest that training using GTLI and BWST has similar effects on improving the gait and balance abilities. Conversely, training using GTLI is more effective in improving the lower-limb muscle strength than that using BWST.

Research Poster 635 Effects of Gait Training with a Hybrid Assistive LimbÒ in Stroke Patients: A Randomized Controlled Study with a 2-month Follow-up Hiroki Watanabe (University of Tsukuba), Naoki Tanaka, Ryohei Goto, Hisako Yanagi Research Objectives: To compare the medium-term efficacy of gait training using a single-leg version of the Hybrid Assistive LimbÒ (HAL) on the paretic side with conventional gait training (CGT) in recovery phase stroke patients. Design: Randomized, open controlled trial with a 2-month follow-up. Setting: Hospitalized care. Participants: Out of a convenience sample of 47 patients who fulfilled the study criteria, 14 refused to participate. After randomization, 9 patients withdrew, leaving a total of 24 poststroke participants (HAL group: n Z 12, conventional group: n Z 12) who completed the randomized clinical trial. Interventions: Over 4 weeks, all the participants received twelve 20-minute sessions of either HAL (using the single-leg version of HAL on the paretic side) or CGT (performed by skilled and experienced physical therapists). Main Outcome Measure(s): The outcome measures were evaluated prior to training, after 12 sessions (4 weeks), and at 8 and 12 weeks after intervention initiation. The Functional Ambulation Category (FAC) was the primary outcome measure, whereas maximum walking speed, timed up-and-go test, 6-minute walk distance, and the FuglaˆV“Meyer assessment of the lower extremity were the secondary outcome measures. Results: The HAL group showed significant improvement in FAC after 12 sessions, and at 8 and 12 weeks compared with the conventional group (95% Confidence interval, 0.09-0.90; P Z 0.02). However, the secondary outcome measures did not differ between the two groups.

e97 Conclusions: The results obtained in this randomized controlled trial suggest that a gait training program based on HAL may improve independent walking more efficiently compared with the conventional gait training after 2 months as well as just 1 month after the intervention.

Research Poster 637 Pain, Function and Unmet Health-care Needs in Hospitalized Victims 3 Years After the Terror Attacks in Norway July 22nd 2011 Grethe Maanum (Sunnaas Rehabilitation Hospital), Kristin Wisløff-Aase, Marianne Løvstad, Johan Kvalvik Stanghelle, Anne Kristine Schanke, Ingar Larsen, Johan Ræder Research Objectives: To describe pain, function, life-satisfaction and long-term health care needs, and to explore the association between pain and physical, psychological and cognitive functioning. Design: Cross-sectional with retrospective acute medical data. Setting: Out-patient rehabilitation clinic, 3 years after injury. Participants: Surviving victims hospitalized with physical injuries due to the terror attacks in Norway July 22nd 2011. Interventions: Not applicable. Main Outcome Measure(s): Injury type and severity, presence and intensity of pain and neuropathic pain, neuropsychological status, subjective cognitive complaints, life satisfaction, and unmet health care needs. Results: Thirty of the 43 hospitalized victims participated in the study. Sixty percent were initially severely injured (e.g. NISS score 15). Twenty-four (80%) reported injury related pain (53% neuropathic pain). The median pain severity on a 0-10 NRS scale was 6.5 [Q1- Q3Z3.25-7.75]. Pain was reported to impair sleep quality in 10, daily activities or work abilities in 12 and quality of life in 15. There were strong and significant negative correlations between mean pain previous week and both physical (rZ -0.49) and psychological (rZ -0.41) life satisfaction, and also between mean pain previous week and subjective experience of memory, concentration and overall psychological health (r range 0.44-0.57). Seventeen patients (57%) were in need of subsequent additional health care, as 11 were referred to pain clinics, four to physiotherapist, six to psychologist, and three to rehabilitation, following participation in the study. Conclusions: Three years after a terror attack, there was a high incidence of chronic pain in victims with physical trauma, resulting in limitations in daily activities, working abilities and life satisfaction. It was shown that a majority still was in need of specialist health care, and the study identified unmet health care needs in 17 of 30 participants.

Research Poster 638 Can Everyday Technology Use Predict Need of Support in Daily Life Among Older Adults with Cognitive Impairment? Charlotta Ryd (Karolinska Institutet), Anders Kottorp, Louise Nyga˚rd, Camilla Malinowsky, Annika O¨hman Research Objectives: To investigate whether use of everyday technology measured by the Everyday Technology Use Questionnaire (ETUQ), can predict overall function among older adults with cognitive impairments. Design: Non-experimental and observational study. Setting: Participants were recruited from out-patient memory investigation units in the Stockholm area. Data collection took place in the participants own homes. Participants: Participants were older adults with AD at a mild stage (n Z 39) or MCI (n Z 28) meeting the following criteria: being 55 years or
