Enhancing Client-Centeredness In Parkinson's Disease Care: Attending To The Psychosocial Implications Of Lived Experience, Jeffrey Holmes, Sara Lutz, Mike Ravenek, Debbie Rudman, Andrew Johnson Oct 2013

Enhancing Client-Centeredness In Parkinson's Disease Care: Attending To The Psychosocial Implications Of Lived Experience, Jeffrey Holmes, Sara Lutz, Mike Ravenek, Debbie Rudman, Andrew Johnson

Andrew M. Johnson

Evidence-based practice requires that clinicians interpret the best research evidence in the context of their clinical experience, while at the same time considering client knowledge and experiences. Although clinicians are becoming increasingly skilled at the evaluation of research evidence, the evidence-based practice process often neglects client values and self-identified health issues. Ignoring these key aspects of client-centered practice may lead to interventions that fail to target the implications of a client’s disease that are important to occupational participation and quality of life (QOL). A focus on client-centeredness is particularly important in progressive neurodegenerative disorders, such as Parkinson’s disease, where there …

A Meta-Analysis Of The Reading Comprehension Skills Of Individuals On The Autism Spectrum, Heather Brown, Janis Cardy, Andrew Johnson Dec 2012

A Meta-Analysis Of The Reading Comprehension Skills Of Individuals On The Autism Spectrum, Heather Brown, Janis Cardy, Andrew Johnson

Andrew M. Johnson

This meta-analysis examined 36 studies comparing autism spectrum disorder (ASD) and control groups in reading comprehension. Three moderators (semantic knowledge, decoding skill, PIQ) and two text types (high vs. low social knowledge) were examined as predictors of reading comprehension in ASD. The overall standardized mean difference for reading comprehension was g = -0.7 SD. The strongest individual predictors of reading comprehension were semantic knowledge (explaining 57 % of variance) and decoding skill (explaining 55 % of variance). Individuals with ASD were significantly worse at comprehending highly social than less social texts. Having ASD alone does not predict reading comprehension deficits. …


The Effects Of A Home-Based Virtual Reality Rehabilitation Program On Balance Among Individuals With Parkinson's Disease, Jeffrey Holmes, Michelle Gu, Andrew Johnson, Mary Jenkins Dec 2012

The Effects Of A Home-Based Virtual Reality Rehabilitation Program On Balance Among Individuals With Parkinson's Disease, Jeffrey Holmes, Michelle Gu, Andrew Johnson, Mary Jenkins

Andrew M. Johnson

Background and Purpose: Recently, the Nintendo Wii has emerged as an innovation in rehabilitation. Although research findings to date have contributed to our understanding of the effects of implementing the Wii as a rehabilitation tool, evidence supporting the Wii for improving symptoms in Parkinson's disease (PD) remains limited. The purpose of this study, therefore, was to evaluate the effectiveness of a 12-week home-based exercise program designed around the Wii, in improving balance, balance confidence, and maintaining exercise adherence among individuals with PD. Methods: Fifteen participants were recruited to engage in 30 minutes of Wii activity 3×/week for 12 weeks. Results: …


Predictive Validity Of The Updrs Postural Stability Score And The Functional Reach Test, When Compared With Ecologically Valid Reaching Tasks, M. E. Jenkins, Andrew M. Johnson, J. D. Holmes, F. F. Stephenson, S. J. Spaulding Mar 2012

Predictive Validity Of The Updrs Postural Stability Score And The Functional Reach Test, When Compared With Ecologically Valid Reaching Tasks, M. E. Jenkins, Andrew M. Johnson, J. D. Holmes, F. F. Stephenson, S. J. Spaulding

Andrew M. Johnson

Balance problems and falls are a common concern among individuals with Parkinson's disease (PD). Falls frequently occur during daily activities such as reaching into cupboards in the kitchen or bathroom. This study compared the correlation among two standard postural stability tests - the postural stability score on the Unified Parkinson's Disease Rating Scale (UPDRS) and the Functional Reach Test (FRT) - and ecologically valid reaching tasks that correspond to reaching at different cupboard heights among 20 individuals with PD and 20 age-matched controls. Both the FRT and the UPDRS postural stability tests are quick measures that can be performed during …


Predicting Residential Treatment Outcomes For Emotionally And Behaviorally Disordered Youth: The Role Of Pretreatment Factors, Wendy Den Dunnen, Jeff St. Pierre, Shannon Stewart, Andrew Johnson, Steven Cook, Alan Leschied Jan 2012

Predicting Residential Treatment Outcomes For Emotionally And Behaviorally Disordered Youth: The Role Of Pretreatment Factors, Wendy Den Dunnen, Jeff St. Pierre, Shannon Stewart, Andrew Johnson, Steven Cook, Alan Leschied

Andrew M. Johnson

This study examined outcomes with 170 children and youth admitted to residential treatment with complex mental health problems. Overall, outcomes at 2 years post-treatment was predicted by children and youth's behavioral pretreatment status reflected in lower internalizing and externalizing behavior at admission. These findings recognize a cluster of variables upon admission that are differentially predictive of specific outcomes. Higher school participation/achievement and an absence of witnessing interparental abuse predicted educational status. Family status was predicted at admission by higher family functioning, being younger in the family, and children and youth who had poor community behavior. The results are discussed as …


Beyond Traditional Notions Of Validity: Selecting Appropriate Measures For Occupational Therapy Practice., Andrew Johnson, Briana Zur, Eric Roy, Debbie Laliberte-Rudman, Jennie Wells Dec 2011

Beyond Traditional Notions Of Validity: Selecting Appropriate Measures For Occupational Therapy Practice., Andrew Johnson, Briana Zur, Eric Roy, Debbie Laliberte-Rudman, Jennie Wells

Andrew M. Johnson

Increasingly, tied to factors such as increased emphasis on accountability and health care spending restraints, occupational therapists are required to implement evidence-based practice. When implementing evidence-based assessment, it is critical that occupational therapists examine and challenge some of the assumptions underlying the current use of measures, as well as the conclusions being drawn from their use. In order to most effectively judge the appropriateness of measures informing their assessments, interventions and recommendations, occupational therapists must draw upon measurement theory and concepts. To date, occupational therapy literature has predominantly emphasized a narrow conceptualization of validity that focuses on empirical evidence. The …

A Prospective Study Of Physician-Observed Concussion During A Varsity University Hockey Season: Metabolic Changes In Ice Hockey Players., Emilie Chamard, Hugo Theoret, Elaine Skopelja, Lorie Forwell, Andrew Johnson, Paul Echlin

Andrew M. Johnson

Object. Despite negative neuroimaging findings using traditional neuroimaging methods such as MRI and CT, sports-related concussions have been shown to cause neurometabolic changes in both the acute and subacute phases of head injury. However, no prospective clinical study has used an independent physician-observer design in the monitoring of these changes. The objective of this study was to evaluate the effects of repetitive concussive and subconcussive head impacts on neurometabolic concentrations in a prospective study of two Canadian Interuniversity Sports (CIS) ice hockey teams using MR spectroscopy (MRS). Methods. Forty-five ice hockey players (25 men and 20 women) participated in this …

Participants underwent pre- and postseason 3-T MRI, including DTI. Group analyses were performed using paired-group tract-based spatial statistics to test for differences between preseason and postseason changes. Results. Tract-based spatial statistics revealed an increase in trace, radial diffusivity (RD), and …


The Effects Of Word Length, Articulation, Oral-Motor Movement, And Lexicality On Gait: A Pilot Study, K. Davie, Janis Cardy, J. Holmes, M. Gagnon, A. Hyde, M. Jenkins, Andrew Johnson Dec 2011

The Effects Of Word Length, Articulation, Oral-Motor Movement, And Lexicality On Gait: A Pilot Study, K. Davie, Janis Cardy, J. Holmes, M. Gagnon, A. Hyde, M. Jenkins, Andrew Johnson

Andrew M. Johnson

Previous research has suggested that articulatory demands are important predictors of the impact of dual-task interference on spatial-temporal parameters of gait. In this study, we evaluated the effects of word length, oral-motor movement, articulation, and lexicality, within a verbal task, on a continuous gait task. Fifteen healthy young women participated in a study in which two word lengths (monosyllabic and bisyllabic) were crossed with four levels of secondary task complexity (no dual-task, non-speech movement, spoken non-word, and spoken word). Spatial and temporal parameters of gait were measured using a 23' instrumented carpet. Results indicated a significant multivariate main effect for …


Identifying And Managing Caregiver Burden Among Spouses Of Individuals With Parkinson's Disease, Kaitlyn Roland, Andrew Johnson, Mary Jenkins Oct 2011

Identifying And Managing Caregiver Burden Among Spouses Of Individuals With Parkinson's Disease, Kaitlyn Roland, Andrew Johnson, Mary Jenkins

Andrew M. Johnson

Burden is a psychological concept, a subjective interpretation by caregivers of the extent to which the caregiving experience impacts on one's health, social life, or financial status. In this article, we examine some of the predictors of caregiver burden, and look specifically at the burden experienced by caregivers of individuals with Parkinson's disease.


Symptom Persistence In Seriously Emotionally Disordered Children: Findings Of A Two-Year Follow-Up After Residential Treatment, Rebecca Cuthbert, Jeff St. Pierre, Shannon Stewart, Steven Cook, Andrew Johnson, Alan Leschied Jul 2011

Symptom Persistence In Seriously Emotionally Disordered Children: Findings Of A Two-Year Follow-Up After Residential Treatment, Rebecca Cuthbert, Jeff St. Pierre, Shannon Stewart, Steven Cook, Andrew Johnson, Alan Leschied

Andrew M. Johnson

Residential treatment is arguably the most costly and intensive part of the children’s mental health system. Yet, research suggests that a subset of the emotionally disordered children and youth admitted to intensive tertiary care treatment facilities fail to demonstrate symptom reductions upon discharge, with many continuing to deteriorate in their adjustment during the follow-up period. This study reports on the factors that characterize the children and youth that, while showing marginal benefit from residential treatment, continue to show community conduct problems at a two-year follow-up period. The results are discussed in the context of how knowledge of these factors can …


Identification And Management Of Impulse Control Disorders Among Individuals With Parkinson’S Disease, Andrew Johnson, H. Hyson, Kaitlyn Roland Apr 2011

Identification And Management Of Impulse Control Disorders Among Individuals With Parkinson’S Disease, Andrew Johnson, H. Hyson, Kaitlyn Roland

Andrew M. Johnson

Although Parkinson’s disease is primarily considered to be a motor disorder, it has inarguable effects on cognition and personality. The cluster of neuropsychiatric sequelae known as impulse-control disorders has been of particular interest in recent years, perhaps owing to the potentially disastrous effects that such behaviors can have on individuals and families. Research has suggested that impulse control disorders are significantly more prevalent among individuals with Parkinson’s disease, particularly with regards to pathological gambling and hypersexuality, and has further suggested that these disorders are significantly and substantively affected by the use of dopamine agonists. Treatment options for impulse control disorders …


The Trajectory Of Change For Children And Youth In Residential Treatment, J. Noftle, Steven Cook, Alan Leschied, Jeff St. Pierre, Shannon Stewart, Andrew Johnson Jan 2011

The Trajectory Of Change For Children And Youth In Residential Treatment, J. Noftle, Steven Cook, Alan Leschied, Jeff St. Pierre, Shannon Stewart, Andrew Johnson

Andrew M. Johnson

This study examined the symptom response trajectories for 225 children and youth throughout a period of residential treatment. With the 10-item Conners' Global Index (CGI) as the primary outcome measure, assessments were completed on a bi-weekly basis during the average 4 month stay within the youth's residential treatment. Clients demonstrated an ongoing reduction of symptoms, and the severity of baseline symptoms influenced the trajectory of the symptom reduction. In addition, symptom reduction was characterized as logarithmic, particularly when controlling for the baseline severity of symptoms. Implications of these findings for administrators, practitioners, and researchers of residential treatment are discussed.

The Contribution Of Processing Impairments To Sli: Insights From Attention-Deficit/Hyperactivity Disorder, Janis Cardy, Rosemary Tannock, Andrew Johnson, Carla Johnson Feb 2010

The Contribution Of Processing Impairments To Sli: Insights From Attention-Deficit/Hyperactivity Disorder, Janis Cardy, Rosemary Tannock, Andrew Johnson, Carla Johnson

Andrew M. Johnson

Slowed speed of processing and impaired rapid temporal processing (RTP) have been proposed to underlie specific language impairment (SLI), but it is not clear that these dysfunctions are unique to SLI. We considered the contribution of attention-deficit/hyperactivity disorder (ADHD), which frequently co-occurs with language impairments, to performances on processing tasks. School-aged children who had SLI without concurrent ADHD (n=14), ADHD without concurrent SLI (n=14), and typical development (TD, n=28) performed two nonverbal speeded tasks and one auditory RTP task. RTP impairments were found in many children with SLI and ADHD, and some children with TD. Children with ADHD demonstrated slower …


Dual-Task Interference: The Effects Of Verbal Cognitive Tasks On Upright Postural Stability In Parkinson's Disease, J. Holmes, M. Jenkins, Andrew Johnson, S. Adams, S. Spaulding Feb 2010

Dual-Task Interference: The Effects Of Verbal Cognitive Tasks On Upright Postural Stability In Parkinson's Disease, J. Holmes, M. Jenkins, Andrew Johnson, S. Adams, S. Spaulding

Andrew M. Johnson

Although dual-task interference has previously been demonstrated to have a significant effect on postural control among individuals with Parkinson's disease, the impact of speech complexity on postural control has not been demonstrated using quantitative biomechanical measures. The postural stability of twelve participants with idiopathic Parkinson's disease and twelve healthy age-matched controls was evaluated under three conditions: (1) without a secondary task, (2) performing a rote repetition task and (3) generating a monologue. Results suggested a significant effect of cognitive load on biomechanical parameters of postural stability. Although both groups increased their postural excursion, individuals with Parkinson's disease demonstrated significantly reduced …


An Exploration Of The Burden Experienced By Spousal Caregivers Of Individuals With Parkinson's Disease, Kaitlyn Roland, Mary Jenkins, Andrew Johnson Jan 2010

An Exploration Of The Burden Experienced By Spousal Caregivers Of Individuals With Parkinson's Disease, Kaitlyn Roland, Mary Jenkins, Andrew Johnson

Andrew M. Johnson

Although previous research has attempted to identify the needs of caregivers for individuals with Parkinson's disease (PD), most has focused on the demands associated with the physical needs of the patient, and not on "mental burden." This study used the repertory grid method to capture the full range of caregivers' subjective experience, quantify their perceptions, and to acquire information that might be useful in directing remediation attempts. Within this sample, caregivers reported far greater burden from "mental stress" (e.g., worrying about individual's safety) than from "physical stress" (e.g., lifting individual into bed). Specifically, caregivers were primarily concerned about spousal safety, …

Plantar Cutaneous Sensory Stimulation Improves Single-Limb Support Time, And Emg Activation Patterns Among Individuals With Parkinson's Disease, M. Jenkins, Q. Almeida, S. Spaulding, R. Van Oostveen, J. Holmes, Andrew Johnson, S. Perry Nov 2009

Plantar Cutaneous Sensory Stimulation Improves Single-Limb Support Time, And Emg Activation Patterns Among Individuals With Parkinson's Disease, M. Jenkins, Q. Almeida, S. Spaulding, R. Van Oostveen, J. Holmes, Andrew Johnson, S. Perry

Andrew M. Johnson

Parkinson's disease is a chronic neurological disorder that results in gait and posture impairment. There is increasing evidence that these motor impairments may be partially due to deficits within the sensory system. In this study, the effects of a facilitatory insole that provides increased plantar sensory stimulation, was evaluated during gait, in a group of individuals with Parkinson's disease in comparison with healthy age-matched controls. Spatial-temporal parameters of gait were evaluated using an instrumented carpet, and muscle activation patterns were evaluated using surface EMG. All participants were tested with both a facilitatory (ribbed) insole and a conventional (flat) insole while …


Dual Task Performance In A Healthy Young Adult Population: Results From A Symmetric Manipulation Of Task Complexity And Articulation, Albert Armieri, Jeffrey Holmes, Sandi Spaulding, Mary Jenkins, Andrew Johnson Jan 2009

Dual Task Performance In A Healthy Young Adult Population: Results From A Symmetric Manipulation Of Task Complexity And Articulation, Albert Armieri, Jeffrey Holmes, Sandi Spaulding, Mary Jenkins, Andrew Johnson

Andrew M. Johnson

The ability to execute and maintain gait while performing simultaneous cognitive, verbal, or motor tasks ('dual-tasking') is beneficial in many ways. It is well-documented, however, that dual-tasking can result in cognitive or motoric interference that results in diminished gait performance, and impaired secondary task performance. When manipulating cognitive load, it is common to have participants respond verbally to stimuli. While this is an ecologically valid way to measure the effects of cognitive load on gait, it ignores the additional demands inherent in the verbal aspect of the task. In the present study, we manipulated complexity and articulation within a single …

The Impact Of Exercise Rehabilitation And Physical Activity On The Management Of Parkinson's Disease, Andrew Johnson, Q. Almeida Dec 2006

The Impact Of Exercise Rehabilitation And Physical Activity On The Management Of Parkinson's Disease, Andrew Johnson, Q. Almeida

Andrew M. Johnson

Although medication therapy is generally effective in the clinical management of Parkinson's disease (PD), additional improvement of some gross motor symptoms may be achieved through the use of nonpharmacological treatments, such as physical therapy and exercise rehabilitation. Despite the fact that PD is a neurological disorder, successful rehabilitation has been demonstrated with treatments that combine cognitive and physical approaches. While the exact mechanism through which these therapies obtain successful outcomes is still largely unknown, it is worthwhile to explore these adjunctive approaches to treating the motor output symptoms of PD.


The Bench To Practice To Bench Cycle Of Evidence-Based Practice, Jb Orange, Andrew Johnson Dec 2005

The Bench To Practice To Bench Cycle Of Evidence-Based Practice, Jb Orange, Andrew Johnson

Andrew M. Johnson

Evidence based clinical practice (EBCP) is a concept that has been discussed in various iterations by healthcare scientists and practitioners over the past half-century. EBCP refers generally to the use of empirical data combined with clinical expertise and end-user (i.e., patient) values to inform and to change clinical activities (Sackett et al., 2000). EBCP originated within the field of medicine, and as result its practice is heavily steeped in medical research paradigms. Over the past two decades, however, it has risen to prominence in both speech science and the profession of speech-language pathology. The emerging emphasis on EBCP seems to …

Evaluating Clinical Rating Scales For Evidence-Based Dermatology: Some Basic Concepts, Madhulika Gupta, Andrew Johnson, Mary-Margaret Chren Sep 2005

Evaluating Clinical Rating Scales For Evidence-Based Dermatology: Some Basic Concepts, Madhulika Gupta, Andrew Johnson, Mary-Margaret Chren

Andrew M. Johnson

Evidence-based dermatology has necessitated the development of rating scales that measure multidimensional and abstract constructs, such as quality of life. This article discusses some basic psychometric concepts, such as reliability, validity, standardization, and measurement precision, which need to be considered when choosing a clinical rating instrument. Also discussed is the impact of these parameters on increasing the statistical power of a clinical trial.
