Dancing for Parkinson's Disease Online: Clinical Trial Process Evaluation. Healthcare (Basel) 2023; 11:healthcare11040604. [PMID: 36833138 PMCID: PMC9957486 DOI: 10.3390/healthcare11040604] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 02/06/2023] [Accepted: 02/09/2023] [Indexed: 02/22/2023] Open
Abstract
Background: Dancing is an engaging physical activity for people living with Parkinson's disease (PD). We conducted a process evaluation for a PD trial on online dancing. Methods: "ParkinDANCE Online" was co-produced by people with PD, healthcare professionals, dance instructors, and a PD organisation. The evaluation mapped the following inputs: (i) stakeholder steering group to oversee program design, processes, and outcomes; (ii) co-design of online classes, based on a research evidence synthesis, expert advice, and stakeholder recommendations; (iii) trial fidelity. The key activities were (i) the co-design of classes and instruction manuals, (ii) the education of dance teachers, (iii) fidelity checking, (iv) online surveys, (v) and post-trial focus groups and interviews with participants. The outputs pertained to: (i) recruitment, (ii) retention, (iii) adverse events, (iv) fidelity, (v) protocol variations, and (vi) participant feedback. Results: Twelve people with PD, four dance instructors and two physiotherapists, participated in a 6-week online dance program. There was no attrition, nor were there any adverse events. Program fidelity was strong with few protocol variations. Classes were delivered as planned, with 100% attendance. Dancers valued skills mastery. Dance teachers found digital delivery to be engaging and practical. The safety of online testing was facilitated by careful screening and a home safety checklist. Conclusions: It is feasible to deliver online dancing to people with early PD.

Abstract
BACKGROUND Therapeutic dancing can be beneficial for people living with Parkinson's disease (PD), yet community-based classes can be difficult to access. OBJECTIVE To evaluate the feasibility and impact of online therapeutic dancing classes for people in the early to mid-stages of PD. METHODS Co-produced with people living with PD, physiotherapists, dance teachers and the local PD association, the 'ParkinDANCE' program was adapted to enable online delivery during the COVID-19 pandemic. Participants completed 8 one-hour sessions of online therapeutic dancing. Each person was assigned their own dance teacher and together they selected music for the classes. A mixed-methods design enabled analysis of feasibility and impact. Feasibility was quantified by attendance and adverse events. Impact was determined from individual narratives pertaining to consumer experiences and engagement, analysed with qualitative methods through a phenomenological lens. RESULTS Attendance was high, with people attending 100% sessions. There were no adverse events. Impact was illustrated by the key themes from the in-depth interviews: (i) a sense of achievement, enjoyment and mastery occurred with online dance; (ii) project co-design facilitated participant engagement; (iii) dance instructor capabilities, knowledge and skills facilitated positive outcomes; (iv) music choices were key; and (v) participants were able to quickly adapt to online delivery with support and resources. CONCLUSIONS Online dance therapy was safe, feasible and perceived to be of benefit in this sample of early adopters. During the pandemic, it was a viable form of structured physical activity. For the future, online dance may afford benefits to health, well-being and social engagement.

Factors associated with improved walking in older people during hospital rehabilitation: secondary analysis of a randomized controlled trial. BMC Geriatr 2021; 21:90. [PMID: 33517882 PMCID: PMC7847572 DOI: 10.1186/s12877-021-02016-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Accepted: 01/10/2021] [Indexed: 11/20/2022] Open
Abstract
Background Older people are often admitted for rehabilitation to improve walking, yet not everyone improves. The aim of this study was to determine key factors associated with a positive response to hospital-based rehabilitation in older people. Methods This was a secondary data analysis from a multisite randomized controlled trial. Older people (n= 198, median age 80.9 years, IQR 76.6- 87.2) who were admitted to geriatric rehabilitation wards with a goal to improve walking were recruited. Participants were randomized to receive additional daily physical therapy focused on mobility (n = 99), or additional social activities (n = 99). Self-selected gait speed was measured on admission and discharge. Four participants withdrew. People who changed gait speed ≥0.1 m/s were classified as ‘responders’ (n = 130); those that changed <0.1m/s were classified as ‘non-responders’ (n = 64). Multivariable logistic regression explored the association of six pre-selected participant factors (age, baseline ambulation status, frailty, co-morbidities, cognition, depression) and two therapy factors (daily supervised upright activity time, rehabilitation days) and response. Results Responding to rehabilitation was associated with the number of days in rehabilitation (OR 1.04; 95% CI 1.00 to 1.08; p = .039) and higher Mini Mental State Examination scores (OR 1.07, 95% CI 1.00 – 1.14; p = .048). No other factors were found to have association with responding to rehabilitation. Conclusion In older people with complex health problems or multi-morbidities, better cognition and a longer stay in rehabilitation were associated with a positive improvement in walking speed. Further research to explore who best responds to hospital-based rehabilitation and what interventions improve rehabilitation outcomes is warranted.

Home-Based Gait Training Using Rhythmic Auditory Cues in Alzheimer's Disease: Feasibility and Outcomes. Front Med (Lausanne) 2020; 6:335. [PMID: 32083083 PMCID: PMC7005067 DOI: 10.3389/fmed.2019.00335] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2019] [Accepted: 12/23/2019] [Indexed: 01/28/2023] Open
Abstract
Background/Purpose: Although gait disorders occur early in the course of Alzheimer's disease (AD) and increase the risk of falling, methods to improve walking in the home setting are poorly understood. This study aimed to determine the feasibility of a home-based gait training program using rhythmic auditory cues for individuals living with mild to moderately severe AD. Methods: Participants had probable AD with no other major conditions affecting locomotion. The intervention consisted of eight progressively modified 45-min gait training sessions delivered during home visits over 4 weeks. Experienced physiotherapists provided the therapy that incorporated rhythmic music cues for a range of locomotor tasks and ambulatory activities. On the days when the physiotherapist did not attend, participants independently performed a seated music listening activity. Walking speed, cadence, stride length, double limb support duration, and gait variability (coefficient of variation) were measured using an 8-m GAITRite® computerized walkway immediately before and after the physiotherapy intervention. Participant satisfaction was also assessed using a purpose-designed questionnaire. Results: Eleven (median age, 77.0 years; median ACE III score, 66/100; 3 females and 8 males) community-dwelling adults living with AD participated. Wilcoxon signed rank tests revealed statistically significant increases in gait speed following the home-based physiotherapy intervention (baseline = 117.5 cm/s, post-intervention = 129.9 cm/s, z = −2.40, p < 0.05). Stride length also improved (baseline = 121.8 cm, post-intervention = 135.6 cm, z = −2.67, p < 0.05). There was no significant change in gait variability. The program was found to be feasible and safe, with no attrition. Participant satisfaction with the home-based music-cued gait training was high, and there were no adverse events. Conclusion: A progressively modified gait training program using rhythmic auditory cues delivered at home was feasible, safe, and enjoyable. Music-cued gait training can help to reduce the rate of decline in gait stride length and speed in some individuals living with AD.

Abstract
Background Adults who live in residential aged care can have reduced participation in physical activities and sit for prolonged periods. Therapeutic dancing aims to optimize movement, creative expression, well-being, and social interaction. Objectives To investigate the benefits, challenges, and facilitators to implementing therapeutic dancing in residential aged care. Methods Thematic analysis of semistructured interviews of residential aged care staff and therapists. Interviews were digitally audio-recorded and thematically analyzed. Findings: Four main themes were identified: (a) despite frailty, dancing classes afforded motor and nonmotor benefits, (b) music and dance genre selections were key to success, (c) the skills of the dance instructor were associated with successful outcomes, and (d) there were modifiable and nonmodifiable facilitators and barriers to implementation. Conclusion Enablers included support from management, resident supervision, age-appropriate music with a strong rhythmical beat, and a dance instructor skilled in comprehensive care. Barriers included multimorbidity, frailty, severe cognitive impairment, and funding.

A Home-Based, Music-Cued Movement Program Is Feasible and May Improve Gait in Progressive Supranuclear Palsy. Front Neurol 2019; 10:116. [PMID: 30837939 PMCID: PMC6389624 DOI: 10.3389/fneur.2019.00116] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Accepted: 01/29/2019] [Indexed: 01/16/2023] Open
Abstract
Objectives: To understand the benefits and feasibility of using supervised, home-based, music-cued training to improve gait speed and stability in community-dwelling people with Progressive Supranuclear Palsy. Design: Feasibility trial incorporating a single group repeated-measures design. Setting: Human movement laboratory and participants' homes. Interventions:Two training sessions per week, conducted by experienced physiotherapists over 4 weeks. Each home training session consisted of a range of activities in standing or walking, with, and without auditory cues. Rhythmic auditory cues were played via a portable digital music player and consisted of metronome beats and individually chosen, commercially available rhythmic music tracks. Main Outcome Measures: Spatiotemporal gait measures were recorded using an 8 m long GAITRite® mat. Participants walked without cues at self-selected comfortable pace. The Progressive Supranuclear Palsy and Unified Parkinson's Disease Rating Scales were administered at baseline. Addenbrooke's Cognitive Examination-III, Geriatric Depression Scale, Assessment of Personal Music Preference Scale, and Physiological Profile Assessment were administered at baseline and retest. Results: At baseline, two of the five community-dwelling participants with Progressive Supranuclear Palsy walked with normal speed and low gait variability. Of the remainder who walked with slower, more variable patterns, two walked faster at retest, one by a clinically meaningful amount. Four participants reduced their timing variability at retest and three reduced step length variability. All participants reported high satisfaction levels with the program. Conclusions: When delivered at home with the support of caregivers, music-cued gait training can provide a feasible approach to improving disorders of gait stability in people with this rare, degenerative condition. Movement to music is engaging and enjoyable which can facilitate adherence to therapy. Clinical Trial Registration : ANZCTR 12616000851460. http://www.anzctr.org.au/

Abstract
QUESTIONS Among older people receiving inpatient rehabilitation, does additional supervised physical activity lead to faster self-selected gait speed at discharge? Does additional supervised physical activity lead to better mobility, function and quality of life at discharge and 6 months following discharge? DESIGN Multi-centre, parallel-group, randomised controlled trial with concealed allocation, assessor blinding, and intention-to-treat analysis. PARTICIPANTS Older people (age>60years) from two Australian hospitals undergoing rehabilitation to improve mobility. INTERVENTION Participants received multidisciplinary care, including physiotherapy. During hospital rehabilitation, the experimental group (n=99) spent additional time daily performing physical activities that emphasised upright mobility tasks; the control group (n=99) spent equal time participating in social activities. OUTCOME MEASURES Self-selected gait speed was the primary outcome at discharge and a secondary outcome at the 6-month follow-up. Timed Up and Go, De Morton Mobility Index, Functional Independence Measure and quality of life were secondary outcomes at discharge and tertiary outcomes at the 6-month follow-up. RESULTS The experimental group received a median of 20 additional minutes per day (IQR 15.0 to 22.5) of upright activities for a median of 16.5days (IQR 10.0 to 25.0). Gait speed did not differ between groups at discharge. Mean gait speed was 0.51m/s (SD 0.29) in the experimental group and 0.56m/s (SD 0.28) in the control group (effect size -0.06m/s, 95% CI -0.12 to 0.01, p=0.096). No significant differences were detected in other secondary measures. CONCLUSION While substantial gains in mobility were achieved by older people receiving inpatient rehabilitation, additional physical activity sessions did not lead to better walking outcomes at discharge or 6 months.

Abstract
BACKGROUND Cognitive impairment increases fall risk in older adults. Dual-task testing is an accepted way to assess the interaction between cognition and mobility; however, there is a lack of evidence-based recommendations for dual-task testing to evaluate fall risk in clinical practice. OBJECTIVES To evaluate the association between dual-task testing protocols and future fall risk, and to identify the specific dual-task test protocols associated with elevated risk. DATA SOURCES MEDLINE, Pubmed and EMBASE electronic databases were searched from January 1988 to September 2013. STUDY SELECTION Two independent raters identified prospective cohort studies (duration of at least 1 year) of dual-task assessment in community-dwelling participants aged ≥60 years, with 'falls' as the primary outcome. STUDY APPRAISAL AND SYNTHESIS METHODS Methodological quality was scored independently by two raters using a published checklist of criteria for evaluating threats to the validity of observational studies. RESULTS Deterioration in gait during dual-task testing compared with single-task performance was associated with increased fall risk. Shortcomings within the literature significantly limit knowledge translation of dual-task gait protocols into clinical practice. LIMITATIONS There is a paucity of prospective studies on the association of dual-task gait assessment with fall risk. CONCLUSION AND IMPLICATIONS OF KEY FINDINGS Changes in gait under dual-task testing are associated with future fall risk, and this association is stronger than that for single-task conditions. Limitations in the available literature preclude development of detailed recommendations for dual-task gait testing procedures in clinical practice to identify and stratify fall risk in older adults.

Evaluating the effects of increasing physical activity to optimize rehabilitation outcomes in hospitalized older adults (MOVE Trial): study protocol for a randomized controlled trial. Trials 2015; 16:13.

Abstract
Background Older adults who have received inpatient rehabilitation often have significant mobility disability at discharge. Physical activity levels in rehabilitation are also low. It is hypothesized that providing increased physical activity to older people receiving hospital-based rehabilitation will lead to better mobility outcomes at discharge. Methods/Design A single blind, parallel-group, multisite randomized controlled trial with blinded assessment of outcome and intention-to-treat analysis. The cost effectiveness of the intervention will also be examined. Older people (age >60 years) undergoing inpatient rehabilitation to improve mobility will be recruited from geriatric rehabilitation units at two Australian hospitals. A computer-generated blocked stratified randomization sequence will be used to assign 198 participants in a 1:1 ratio to either an ‘enhanced physical activity’ (intervention) group or a ‘usual care plus’ (control) group for the duration of their inpatient stay. Participants will receive usual care and either spend time each week performing additional physical activities such as standing or walking (intervention group) or performing an equal amount of social activities that have minimal impact on mobility such as card and board games (control group). Self-selected gait speed will be measured using a 6-meter walk test at discharge (primary outcome) and 6 months follow-up (secondary outcome). The study is powered to detect a 0.1 m/sec increase in self-selected gait speed in the intervention group at discharge. Additional measures of mobility (Timed Up and Go, De Morton Mobility Index), function (Functional Independence Measure) and quality of life will be obtained as secondary outcomes at discharge and tertiary outcomes at 6 months follow-up. The trial commenced recruitment on 28 January 2014. Discussion This study will evaluate the efficacy and cost effectiveness of increasing physical activity in older people during inpatient rehabilitation. These results will assist in the development of evidenced-based rehabilitation programs for this population.

The effects of a concurrent motor task on walking in Alzheimer's disease. Gait Posture 2014; 39:291-6.

Abstract
The important relationship between cognition and gait in people with dementia has been explored with dual-task studies using added cognitive tasks. Effects of less commonly studied but also attention-dividing motor dual-tasks are important to assess in this group as they are common in everyday function and may affect gait differently from cognitive dual-tasks. They may also be easier to comprehend allowing their application with more severe cognitive impairment. The aim of this study was to evaluate the effects and feasibility of a motor dual-task (MDT) on gait measures in people with Alzheimer's disease (AD). Thirty people (15 men, mean age ± SD, 80.2 ± 5.8 years) with a diagnosis of probable AD (MMSE range 8-28) walked on an electronic walkway (i) at self-selected comfortable pace and (ii) at self-selected comfortable pace while carrying a tray and glasses. The MDT produced significant decreases in velocity (Baseline=111.5 ± 26.5 cm/s, MDT=96.8 ± 25.7 cm/s, p<0.001) and stride length (Baseline=121.4 ± 21.6 cm, MDT=108.1 ± 21.0 cm, p<0.001) with medium effect sizes, and increased stride time (Baseline=1.11 ± 0.11s, MDT=1.14 ± 0.12s, p=0.001) with small effect size. Measures of spatial (Baseline=3.2 ± 1.0%, MDT=3.9 ± 1.5%, p=0.006) and temporal (Baseline=2.4 ± 0.8%, MDT=2.8 ± 0.8%, p=0.008) variability increased with the motor dual-task, with medium effect sizes. A trend for motor dual-task changes in gait measures to increase with greater disease severity did not reach significance. The tray-carrying task was feasible, even for participants with severe cognitive decline. Further comparison of different types of motor and cognitive dual-tasks may contribute to development of a framework for clinical intervention to improve reduced dual-task walking capacity in people with AD.

Abstract
Gait variability may be especially important to measure in people with Alzheimer's disease (AD) as it is related to risk of falling and may reflect the cognitive demand of walking. Its usefulness as an outcome measure in people with AD is currently limited by the lack of published evaluation of its reproducibility. Therefore measures of temporal and spatial gait variability were recorded using an instrumented mat on two occasions, one week apart in 16 community-dwelling people with mild to moderate probable AD. Data were combined in three ways for analysis: all available strides; all available strides from walks with mean velocity within 10cm/s of each other; and the first 12 strides from the second method. Measures of velocity, stride length and cadence variability were all found to have good reliability using an average of 64 strides from velocity-matched walks (ICC3,1 0.77-0.90) however only stride length variability reached acceptable reliability for a clinical test (ICC3,1 0.9). Estimates of the number of strides required to reach an ICC of 0.9 for velocity, cadence and stride width variability were between 169 and 212. Poor to moderate reliability of gait variability measures was obtained using 12 strides. Minimal detectable change values, calculated to reflect absolute agreement, appear to be feasible and may assist with evaluation of interventions to improve gait. Further research should examine the effects on reproducibility of gait variability measures, of systematic cueing aimed at producing consistent, optimal walking in larger groups with a range of dementia type and severity.

Music and metronome cues produce different effects on gait spatiotemporal measures but not gait variability in healthy older adults. Gait Posture 2013; 37:219-22.

Abstract
Rhythmic auditory cues including music and metronome beats have been used, sometimes interchangeably, to improve disordered gait arising from a range of clinical conditions. There has been limited investigation into whether there are optimal cue types. Different cue types have produced inconsistent effects across groups which differed in both age and clinical condition. The possible effect of normal ageing on response to different cue types has not been reported for gait. The aim of this study was to determine the effects of both rhythmic music and metronome cues on gait spatiotemporal measures (including variability) in healthy older people. Twelve women and seven men (>65 years) walked on an instrumented walkway at comfortable pace and then in time to each of rhythmic music and metronome cues at comfortable pace stepping frequency. Music but not metronome cues produced a significant increase in group mean gait velocity of 4.6 cm/s, due mostly to a significant increase in group mean stride length of 3.1cm. Both cue types produced a significant but small increase in cadence of 1 step/min. Mean spatio-temporal variability was low at baseline and did not increase with either cue type suggesting cues did not disrupt gait timing. Study findings suggest music and metronome cues may not be used interchangeably and cue type as well as frequency should be considered when evaluating effects of rhythmic auditory cueing on gait. Further work is required to determine whether optimal cue types and frequencies to improve walking in different clinical groups can be identified.

Abstract
OBJECTIVE To determine whether rhythmic music and metronome cues alter spatiotemporal gait measures and gait variability in people with Alzheimer disease (AD). DESIGN A repeated-measures study requiring participants to walk under different cueing conditions. SETTING University movement laboratory. PARTICIPANTS Of the people (N=46) who met study criteria (a diagnosis of probable AD and ability to walk 100m) at routine medical review, 30 (16 men; mean age ± SD, 80±6y; revised Addenbrooke's Cognitive Examination range, 26-79) volunteered to participate. INTERVENTIONS Participants walked 4 times over an electronic walkway synchronizing to (1) rhythmic music and (2) a metronome set at individual mean baseline comfortable speed cadence. MAIN OUTCOME MEASURES Gait spatiotemporal measures and gait variability (coefficient of variation [CV]). Data from individual walks under each condition were combined. A 1-way repeated-measures analysis of variance was used to compare uncued baseline, cued, and retest measures. RESULTS Gait velocity decreased with both music and metronome cues compared with baseline (baseline, 110.5cm/s; music, 103.4cm/s; metronome, 105.4cm/s), primarily because of significant decreases in stride length (baseline, 120.9cm; music, 112.5cm; metronome, 114.8cm) with both cue types. This was coupled with increased stride length variability compared with baseline (baseline CV, 3.4%; music CV, 4.3%; metronome CV, 4.5%) with both cue types. These changes did not persist at (uncued) retest. Temporal variability was unchanged. CONCLUSIONS Rhythmic auditory cueing at comfortable speed tempo produced deleterious effects on gait in a single session in this group with AD. The deterioration in spatial gait parameters may result from impaired executive function associated with AD. Further research should investigate whether these instantaneous cue effects are altered with more practice or with learning methods tailored to people with cognitive impairment.

Longitudinal changes in knee joint biomechanics during level walking following anterior cruciate ligament reconstruction surgery. Gait Posture 2012; 36:167-71. [PMID: 22469773 DOI: 10.1016/j.gaitpost.2012.02.004] [Citation(s) in RCA: 50] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2011] [Revised: 02/08/2012] [Accepted: 02/11/2012] [Indexed: 02/02/2023]
Abstract
Following anterior cruciate ligament reconstruction (ACL) patients have altered movement patterns in the reconstructed knee during walking. There is limited information about these alterations over an extended period of time. This study was designed to present a longitudinal analysis of gait patterns following ACL reconstruction surgery. Assessments of level walking were undertaken in 16 participants at a mean 10 months (initial assessment) and again at 3 years (follow-up assessment) after ACL reconstruction surgery. Kinematic and kinetic variables were analysed using a two factor (time, limb) repeated measures ANOVA. Kinematic data showed that patients were able to achieve greater extension about the reconstructed knee at follow-up than at initial assessment. The reconstructed knee was significantly less internally rotated than the contralateral knee at the initial assessment but not at follow-up. Kinetic data showed a significant increase in the external knee extension moment for the reconstructed limb over time. There were also significant increases in the external knee adduction moment for both limbs at the follow-up assessment. The external knee adduction moment was however smaller in the reconstructed knee than the contralateral knee at both assessments. The results indicate that gait variables do change over time and that measurement at a single time point may not reflect the long term outcome of ACL reconstruction surgery. The changes were however small and may not be clinically relevant. However, the consistently reduced external knee adduction moment seen about the reconstructed knee in this study may suggest that factors other than joint moments influence degenerative change over time.

Three dimensional motion analysis of within and between day repeatability of tibial rotation during pivoting. Knee 2010; 17:329-33. [PMID: 19879764 DOI: 10.1016/j.knee.2009.09.007] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2009] [Revised: 09/11/2009] [Accepted: 09/26/2009] [Indexed: 02/02/2023]
Abstract
Activities that involve a change in direction apply a high rotational load to the knee joint. Biomechanical analysis of such activities may be useful for determining mechanisms that underlie knee injury and the success of ligament reconstruction surgery. However, the reliability of the measurement of tibial rotation remains unclear. The purpose of this study was to determine the reliability of tibial rotation measurements during a pivoting task, both between testing sessions conducted on the same day and between those made one week apart. Three-dimensional motion analysis was used to measure peak internal tibial rotation and rotational excursion during a stair descent and pivoting task in eleven healthy subjects (six female, five males). Intraclass correlation coefficients (ICC (3, 1)) and typical error analyses were used to examine within and between day reliability. Tibial rotational excursion had excellent reliability for within day (ICC=0.82) and between day sessions (ICC=0.76) whereas peak internal rotation had good reliability (within ICC=0.74; between ICC=0.68). Typical error was less than 2.4 degrees for within day measures and 2.9 degrees for between day measures. It was concluded that tibial rotation can be measured reliably during pivoting. Typical error values were less than the usual group differences in rotational excursion reported in the literature. The ability to reliably quantify tibial rotation during dynamic activities is important in determining the causes of persisting instability following anterior cruciate ligament reconstruction.

Abstract
BACKGROUND/AIMS Variability of constant speed walking is closely related to falls risk in people with Alzheimer's disease (AD) who fall at 3 times the rate of normal elders. Falls are likely to be provoked during gait initiation, so this study aimed to determine if people with mild-moderate AD have greater variability of gait at initiation. METHODS Measures of step and stride length and time, step width and double support time were recorded during gait initiation for 10 males and 10 females with AD and 20 age- and gender-matched controls. Variability was calculated using the coefficient of variation (CV). Effect size was calculated using Cohen's d. RESULTS During gait initiation AD participants had greater variability than controls in stride timing (AD CV = 4.65, Control CV = 3.64; p < 0.05, d = 0.71) and double support proportion (AD CV = 9.40, Control CV = 7.62; p < 0.05, d = 0.8). CONCLUSION Increased timing variability in people with AD occurs during gait initiation as well as during constant speed walking and is evident in the early disease stages.

Abstract
BACKGROUND Falls are common in people with Alzheimer's disease (AD). There is some evidence that deficits in vision, peripheral sensation, strength, reaction time and balance may be partly responsible for this increased risk. AIMS To determine the feasibility and test-retest reliability of a physiological test battery designed to assess falls risk [the Physiological Profile Assessment (PPA)] in people with AD, and to compare their PPA scores to age- and sex-matched controls. METHODS Twenty-one community-dwelling people with probable, mild to moderate AD aged 63-91 years, and 21 age- and sex-matched controls underwent the PPA tests and the Mini-Mental State Examination. All tests were then repeated in the AD group to determine test-retest reliability. RESULTS Most of the PPA tests could be successfully administered to participants with AD. The AD group had a significantly higher overall falls risk score (t(40) = -2.41, p < 0.02), slower hand (t(40) = -4.86, p < 0.01) and foot reaction time (t(40) = -2.26, p < 0.05) and worse coordinated stability (t(40) = -2.40, p < 0.05) than the controls. CONCLUSION Physiological falls risk assessment is feasible in older people with mild to moderate AD. Older people with AD demonstrate significant impairments in several physiological domains, particularly reaction time, compared to controls.

Abstract
Gait disorders in people with dementia have been documented in a number of studies. There is some preliminary evidence suggesting there may be a relationship between dementia type and gait abnormality. Quantitative gait analysis has not previously been reported for people diagnosed with dementia with Lewy bodies (DLB). Therefore, this study aimed to quantify gait patterns of people with DLB and compare them with those of people with Alzheimer's disease (AD) and control subjects. Two groups of 10 subjects divided according to a diagnosis of DLB and AD, and 10 control subjects underwent gait analysis using an electronic walkway. Participants were required to walk at self-selected slow, preferred and fast speeds. There were no differences between the DLB and AD patient groups for any of the measured gait variables. Velocity and stride length values were significantly reduced in both patient groups compared to the control group at all speeds and percentage of time spent in double limb support was significantly increased in both patient groups compared to the control group at all walking speeds. Significant correlations were found between gait speeds and gait outcome variables. Spatiotemporal gait characteristics of people with AD and DLB are similar, but significantly different from the normal population.

Abstract
This article describes a systematic review and critical evaluation of the international literature on the effects of physical therapy, speech pathology, and occupational therapy for people with motor neuron disease (PwMND). The results were interpreted using the framework of the International Classification of Functioning, Disability and Health. This enabled us to summarize therapy outcomes at the level of body structure and function, activity limitations, participation restrictions, and quality of life. Databases searched included MEDLINE, PUBMED, CINAHL, PSYCInfo, Data base of Abstracts of Reviews of Effectiveness (DARE), The Physiotherapy Evidence data base (PEDro), Evidence Based Medicine Reviews (EMBASE), the Cochrane database of systematic reviews, and the Cochrane Controlled Trials Register. Evidence was graded according to the Harbour and Miller classification. Most of the evidence was found to be at the level of "clinical opinion" rather than of controlled clinical trials. Several nonrandomized small group and "observational studies" provided low-level evidence to support physical therapy for improving muscle strength and pulmonary function. There was also some evidence to support the effectiveness of speech pathology interventions for dysarthria. The search identified a small number of studies on occupational therapy for PwMND, which were small, noncontrolled pre-post-designs or clinical reports.

Abstract
Studies have shown that measures of gait variability are associated with falling in older adults. However, few studies have measured gait variability in people with Alzheimer disease, despite the high incidence of falls in Alzheimer disease. The purpose of this study was to compare gait variability of community-dwelling older adults with Alzheimer disease and control subjects at various walking speeds. Ten subjects with mild-moderate Alzheimer disease and ten matched control subjects underwent gait analysis using an electronic walkway. Participants were required to walk at self-selected slow, preferred, and fast speeds. Stride length and step width variability were determined using the coefficient of variation. Results showed that stride length variability was significantly greater in the Alzheimer disease group compared with the control group at all speeds. In both groups, increases in walking speed were significantly correlated with decreases in stride length variability. Step width variability was significantly reduced in the Alzheimer disease group compared with the control group at slow speed only. In conclusion, there is an increase in stride length variability in Alzheimer disease at all walking speeds that may contribute to the increased incidence of falls in Alzheimer disease.

Abstract
This study compared individual step and averaged spatial and temporal gait parameters measured with an instrumented walkway system (GAITRite) with a three-dimensional motional analysis system (Vicon-512). Ten subjects aged 54-83 years (mean 66.5 years) who had undergone knee replacement surgery participated. Subjects walked across the GAITRite walkway at self-selected comfortable and fast speeds at the same time as the Vicon system recorded the motion of reflective markers attached to the subjects' shoes. Walking speed, cadence, step length and step time variables, averaged across one walk for both systems, showed an excellent level of agreement with intra-class correlation coefficients (ICCs) between 0.92 and 0.99 and repeatability coefficients (RCs) between 1.0% and 5.9% of mean values. Step length and step time variables recorded for each footstep also showed good agreement between the systems at both comfortable and fast speeds (ICCs between 0.91 and 0.99; RCs between 2.6% and 7.8%). Frequency distributions showed that individual step values were within 1.5 cm and 0.02 s on the majority (80-94%) of occasions. These data indicate that the GAITRite system is a valid tool for measuring both averaged and individual step parameters of gait. It is also valid for use in older subjects following knee joint replacement surgery.

Abstract
BACKGROUND Although there is a tendency toward gait normalization after anterior cruciate ligament reconstruction, altered moments about the knee flexion-extension axis have been reported. It is possible that these gait alterations relate to donor site morbidity associated with the graft harvest. HYPOTHESIS There is a relationship between graft type and external knee moments during walking. STUDY DESIGN Controlled laboratory study. METHODS Three groups were compared: 17 patellar tendon anterior cruciate ligament reconstruction patients (mean, 11 months after surgery), 17 hamstring tendon anterior cruciate ligament reconstruction patients (mean, 9.3 months after surgery), and 17 matched controls. A 3-dimensional motion analysis and force plate system was used to determine sagittal plane kinematics and kinetics of the lower limb during comfortable-speed walking. RESULTS There were significant differences in the moments about the knee that related to graft type. The external knee flexion moment at midstance was significantly smaller than that in the control knees in 65% of patients in the patellar tendon group and 29% of patients in the hamstring tendon group. In contrast, the external knee extension moment at terminal stance was significantly smaller than that in the control knees in 53% of subjects in the hamstring tendon group and 23% of subjects in the patellar tendon group. CONCLUSIONS There are graft-specific differences in knee biomechanics after anterior cruciate ligament reconstruction that appear to relate to the donor site. CLINICAL RELEVANCE Considerable debate continues as to whether the patellar tendon or the hamstring tendon graft is preferable for anterior cruciate ligament reconstruction. It is therefore clinically relevant to understand the biomechanical differences in knee function associated with both graft types.

Abstract
This study characterized the footstep pattern and knee kinematics during walking in 12 patients who had undergone unicompartmental knee arthroplasty for unilateral medial compartment osteoarthritis. Patients had all achieved a successful recovery and were tested at least 1 year after surgery. Gait analysis was conducted during self-selected comfortable and fast walking conditions using a 3-dimensional motion analysis system and electronic walkway. Results showed that patients were able to increase their walking speed by 28% by increasing both stride length and cadence. All but one patient showed a biphasic pattern of flexion-extension motion about the treated knee. In 8 of 12 patients, significant increases in knee flexion were seen in the treated limb compared with the contralateral limb, the cause and ramifications of which are yet to be determined.

Abstract
Physiotherapists are required to record treatment time in both clinical research and daily practice. This study aimed to investigate the accuracy of treatment time records using a specific method of defining treatment for patients with stroke. Twenty-six physiotherapists provided time records using this method for one of their treatment sessions, each of which was videotaped. Two physiotherapists observed each videotape and their recorded times were then averaged to provide criterion scores against which clinicians' scores were compared. Clinicians' recordings were mostly of moderate to high accuracy and did not demonstrate systematic errors, despite the potential for accuracy to be compromised by many factors. This study has provided a model of how the accuracy of treatment time records can be validated.
