- Objective: To identify factors associated with preserved walking ability and Katz activities of daily living (ADLs) index at 4-month and 12-month follow-up in cognitively impaired patients with femoral neck fracture. Design: Population-based cohort study. Setting: A multicenter study of the Stockholm Hip Fracture Group including 4 university hospitals. Participants: Consecutive patients (N=246) with femoral neck fracture, older than 65 years (mean, 84y; 72% women) with cognitive impairment (known dementia or low [0-2 points] score) in Short Portable Mental Status Questionnaire [0-10 points]) and able to walk before the fracture. Interventions: Not applicable. Main Outcome Measure: Walking ability and ADLs index at 4-month and 12-month follow-up. Results: Significant predictors of preserved walking ability at 12-month follow-up were discharge to rehabilitation unit (odds ratio [OR]=2.83: confidence interval [CI], 1.1-7.26; P=.03) and walking ability before the fracture (OR=8.98; Cl, 3.52-22.93; P<.001), while type of surgery was not (P=.197). Analyses were adjusted for age, sex, American Society of Anesthesiologists score, fracture type, and surgical method. Corresponding predictors of preserved Katz ADLs index at 12-month follow-up, after adjustment for age and sex, were discharge to rehabilitation unit (OR=5.33; Cl, 1.44-19.65: P=.012) and ADLs index before fracture (OR=2.5; Cl. 1.8-3.5: P<.001), while type of surgery was not (P=.376). Conclusions: Discharge to rehabilitation unit, a factor we can influence, was associated with preserved walking ability and ADLs index in cognitively impaired patients with hip fracture.

- Objectives: To explore and describe the perceived facilitators and barriers to physical activity, and to examine the physical activity correlates in people with Charcot-Marie-Tooth (CMT) disease. Design: Cross-sectional survey study. Setting: Community-living subjects. Participants: Swedish people with CMT disease (N=44; men, 54.5%; median age, 59.5y [interquartile range, 45.3-64.8y]). Interventions: Not applicable. Main Outcome Measures: The survey included open-ended questions and standardized self-reported scales measuring physical activity, fatigue, activity limitation, self-efficacy for physical activity, fall-related self-efficacy, social support, and enjoyment of physical activity. Physical activity was measured by the Physical Activity Disability Survey-Revised. Results: Qualitative content analysis revealed that personal factors such as fatigue, poor balance, muscle weakness, and pain were important barriers for physical activity behavior. Facilitators of physical activity were self-efficacy for physical activity, activity-related factors, and assistive devices. Multiple regression analysis showed that self-efficacy for physical activity (beta=.41) and fatigue (beta=-.30) explained 31.8% of the variation in physical activity (F-2,F-40=10.78, P=.000). Conclusions: Despite the well-known benefits of physical activity, physical activity in people with CMT disease is very sparsely studied. These new results contribute to the understanding of factors important for physical activity behavior in people with CMT disease and can guide health professionals to facilitate physical activity behavior in this group of patients.

- Arnadottir SA, Lundin-Olsson L, Gunnarsdottir ED, Fisher AG. Application of Rasch analysis to examine psychometric aspects of the Activities-Specific Balance Confidence Scale when used in a new cultural context. OBJECTIVE: To investigate by using Rasch analysis the psychometric properties of the Activities-Specific Balance Confidence (ABC) Scale when applied in a new Icelandic context. DESIGN: Cross-sectional, population-based, random selection from the Icelandic National Registry. SETTING: Community-based. PARTICIPANTS: Icelanders (N=183), 65 to 88 years old, and 48% women. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: ABC, an instrument used to evaluate how confident older people are in maintaining balance and remaining steady when moving through the environment. An Icelandic translation of the ABC (ABC-ICE) scale was evaluated by implementing Rasch rating scale analysis to transform ordinal ABC-ICE scores into interval measures and evaluating aspects of validity and reliability of the scale. RESULTS: Participants were not able to differentiate reliably between the 11 rating scale categories of the ABC-ICE. Additionally, 3 items failed to show acceptable goodness of fit to the ABC-ICE rating scale model. By collapsing categories and creating a new 5-category scale, only 1 item misfit. Removing that item resulted in a modified version of ABC-ICE with 5 categories and 15 items. Both item goodness-of-fit statistics and principal components analysis supported unidimensionality of the modified ABC-ICE. The ABC-ICE measures reliably separated the sample into at least 4 statistically distinct strata of balance confidence. Finally, the hierarchical order of item difficulties was consistent with theoretic expectations, and the items were reasonably well targeted to the balance confidence of the persons tested. CONCLUSIONS: Rasch analysis indicated a need to modify the ABC-ICE to improve its psychometric properties. Further studies are needed to determine if similar analyses of other versions of the ABC, including the original one, will yield similar results.

- ObjectiveTo assess whether variables from a postural control test relate to and predict falls efficacy in prosthesis users.DesignTwelve-month within and between subjects repeated measures design. Participants performed the Limits of Stability (LOS) test protocol at study baseline and at 6-month follow-up. Participants also completed the Falls Efficacy Scale-International (FES-I) questionnaire, reflecting the fear of falling, and reported the number of falls monthly between study baseline and 6-month follow-up, and additionally at 9- and 12-month follow-ups.SettingUniversity biomechanics laboratories.ParticipantsA group of active unilateral transtibial prosthesis users of primarily traumatic etiology (PROS) (n=12) with at least one year of prosthetic experience and age and gender matched control participants (CON) (n=12).InterventionsNot applicable.Main Outcome Measure(s)Postural control variables derived from centre of pressure data obtained during the LOS test, which was performed on and reported by the Neurocom Pro Balance Master, namely; reaction time (RT), movement velocity (MVL), endpoint (EPE) and maximum (MXE) excursion and directional control (DCL). Number of falls and total FES-I scores.ResultsDuring the study period, the PROS group had higher FES-I scores (U = 33.5, p =0.02), but experienced a similar number of falls, compared to the CON group. Increased FES-I score were associated with decreased EPE (R=-0.73, p=0.02), MXE (R=-0.83, p<0.01) and MVL (R=-0.7, p=0.03) in the PROS group, and DCL (R=-0.82, p<0.01) in the CON group, all in the backwards direction.ConclusionsStudy baseline measures of postural control, in the backwards direction only, are related to and potentially predictive of subsequent 6-month FES-I scores in relatively mobile and experienced prosthesis users.

- OBJECTIVE: Persons with right and left cerebral vascular accident (RCVA and LCVA) differ in terms of discrete impairments, but there is limited information with regard to how such impairments translate into differences in disability. The following hypotheses were tested: (1) persons with stroke have lower instrumental or domestic activities of daily living (IADL) ability than do matched nondisabled controls, (2) persons with RCVA do not differ from persons with LCVA in IADL ability, and (3) persons with RCVA and LCVA differ in specific motor and process skills that affect IADL performance.DESIGN: Descriptive comparison.SETTING: Subjects were tested in settings where rehabilitation services were received (home or clinic).SUBJECTS: 71 persons with RCVA, 76 persons with LCVA, and 83 community-living nondisabled individuals drawn from the Assessment of Motor and Process Skills (AMPS) database, matched for age, gender, and number of tasks performed.MAIN OUTCOME MEASURE: AMPS, designed to measure type and severity of impairments manifested in the context of IADL performance. The AMPS was administered to all subjects in accordance with standardized testing procedures.RESULTS: The two stroke groups did not differ significantly in IADL ability, but both stroke groups had significantly lower IADL performance than did the nondisabled subjects. On the AMPS motor scale, persons with RCVA demonstrated greater impairment in pacing, transporting, and coordinating two body parts. Persons with LCVA demonstrated greater impairments in calibrating movements. No differences were found between the two groups in AMPS process skills.CONCLUSIONS: Persons with RCVA and LCVA have hemisphere-specific differences in motor impairments, but do not differ significantly in IADL ability.

- OBJECTIVE: To study the effects of a muscle stretching regimen for the rectus femoris muscle on subjective stretch sensation and range of motion (ROM). DESIGN: A 2 x 2 crossover design comprising 2 treatments and 2 intervention periods. SETTING: A military base in Sweden. PARTICIPANTS: A volunteer sample of 29 male military conscripts divided into 2 groups, with each group subjected to both experimental and control treatments at different time periods. INTERVENTION: Two weeks of supervised stretching (4 times/wk) of the rectus femoris muscle (experimental treatment) and the calf muscles (control treatment). MAIN OUTCOME MEASURES: Subjective rating of the stretch sensation for the anterior aspect of the thigh determined on a category ratio scale. Passive knee flexion ROM determined on each test with the same applied torque, specific for each subject. RESULTS: An additive analysis of variance revealed that the stretch sensation after the experimental treatment was decreased, compared with the control treatment (p <.01). The knee flexion, however, remained the same regardless of the treatment. CONCLUSION: Sensory adaptation seems to be an important mechanistic factor in the effect stretching has on ROM changes. The lack of change in knee flexion suggests that the stretching, as performed in this study, did not influence stiffness of the rectus femoris muscle. Sensory adaptation may also be an underlying mechanism in the alleviating effect of stretching when applied to tired, tender, and painful muscles.
