Performance of adults with cerebral palsy related to falls, balance and function: a preliminary report

Motor function and gait decline in individuals with cerebral palsy during adulthood: a narrative review of potential physiological determinants

Cerebral palsy (CP) is the most common childhood-onset disability. The evolution of gait according to severity is well known amongst children and thought to peak between 8 and 12 years of age among those walking without assistive devices. However, among adults, clinical experience as well as scientific studies report, through clinical assessments, questionnaires and interviews, increasing walking difficulties leading to an increased dependency of assistive devices in everyday ambulation. For many individuals with CP, this change will occur around 30-40 years, with the risk of losing mobility increasing with age. This narrative review aims to first provide objective evidence of motor function and gait decline in adults with CP when ageing, and then to offer mechanistic hypotheses to explain those alterations. Many studies have compared individuals with CP to the typically developing population, yet the evolution with ageing has largely been understudied. Comorbid diagnoses comprise one of the potential determinants of motor function and gait decline with ageing in people with CP, with the first manifestations happening at an early age and worsening with ageing. Similarly, ageing appears to cause alterations to the neuromuscular and cardiovascular systems at an earlier age than their typically developing (TD) peers. Future studies should, however, try to better understand how the physiological particularities of CP change with ageing that could pave the way for better strategies for maintaining function and quality of life in people with CP.

The association between isometric strength and cognitive function in adults with cerebral palsy

Background

The literature supports quantifying the maximum force/tension generated by one's forearm muscles such as the hand grip strength (HGS) to screen for physical and cognitive frailty in older adults. Thus, we postulate that individuals with cerebral palsy (CP), who are at higher risk for premature aging, could benefit from tools that objectively measure muscle strength as a functional biomarker to detect frailty and cognitive decline. This study assesses the clinical relevancy of the former and quantifies isometric muscle strength to determine its association with cognitive function in adults with CP.

Methods

Ambulatory adults with CP were identified from a patient registry and were enrolled into this study. Peak rate of force development (RFD) and maximum voluntary isometric contraction of the quadriceps were measured using a commercial isokinetic machine, while HGS was collected with a clinical dynamometer. Dominant and non-dominant side were identified. Standardized cognitive assessments, including the Wechsler Memory and Adult Intelligence Scales IV, Short Test of Mental Status, and the Patient-Reported Outcomes Measurement Information System (PROMIS®) were used to evaluate cognitive function.

Results

A total of 57 participants (32 females; mean age 24.3 [SD 5.3]; GMFCS levels I-IV) were included in the analysis. Although dominant and non-dominant RFD and HGS measures were associated with cognitive function, non-dominant peak RFD showed the strongest associations with cognitive function.

Conclusion

RFD capacity may reflect age-related neural and physical health and could be a better health indicator than HGS in the CP population.

Concurrent validity, test-retest reliability, and sensitivity of a PostureRite system measurement on dynamic postural sway and risk of fall in cerebral palsy

BACKGROUND: Accurately diagnosing dynamic postural sway (DPS) is essential for effective and sustainable intervention in children with cerebral palsy (CP). We developed an accurate, inexpensive, and wearable DPS measurement system to measure DPS accurately and consistently during walking and functional activities of daily living. OBJECTIVE: We investigated the validity and reliability of this PostureRite system in children with CP, and the link between PostureRite and clinical measures including gross motor function measure (GMFM), pediatric balance scale (PBS), and fall efficacy scale (FES). METHODS: Twenty-one participants were categorized as follows: 11 healthy adults (3 females, mean age, 25.00±1.00 years) and 10 children with CP (mean age, 11.10±6.28 years). We determined the concurrent validity of PostureRite by comparing DPS data to the gold standard accelerometer measurement results. We determined test-retest reliability by measuring DPS data on three occasions at 2-h intervals. We assessed PostureRite measurement sensitivity to ascertain differences between healthy children and children with CP DPS measurements. RESULTS: Random and mixed intraclass correlation coefficients (ICC2,k and ICC3,k) were obtained; an independent T-test was performed (P < 0.05). Concurrent validity analysis showed a good relationship between the gold standard accelerometer and PostureRite (ICC2,k = 0.973, P < 0.05). Test-retest reliability demonstrated a good relationship across the three repeated measures of the DPS data (ICC3,k = 0.816–0.924, P < 0.05). Independent T-test revealed a significant difference in DPS data between healthy adults and children with CP (P < 0.05). CONCLUSIONS: We developed a portable, wireless, and affordable PostureRite system to measure DPS during gross motor function associated with daily activity and participation, and established the concurrent validity, test-retest reliability as sensitivity, and clinical relevance by comparing the DPS obtained from the participants with and without CP.

Access, use and satisfaction with physiotherapy services among adults with cerebral palsy living in the United Kingdom and Ireland

PURPOSE

The aims of this study were to describe how and why adults with CP living in the UK and Ireland accessed and used physiotherapy services; to describe the type of physiotherapy accessed and satisfaction with physiotherapy services and to examine the associations between relevant factors.

METHODS

A cross-sectional semi-structured online survey was employed. Participants were adults with CP aged 18 and above living in the UK and Ireland; able to complete an online questionnaire in English independently or with technical or physical assistance. Data were collected from April 2019 to February 2020.

RESULTS

Participants (n = 162) were aged 18-74 years. The majority were female (75%) and lived in the UK (83%). Ninety percent of participants reported a need for physiotherapy but only 35% received physiotherapy services. The most common reason for visiting physiotherapy was mobility decline (62%). Satisfaction with the availability and quality of physiotherapy services were 21% and 27%, respectively. Adults with scoliosis and mobility decline were less likely to report that they received the physiotherapy they needed.

CONCLUSION

Adults with CP did not receive the physiotherapy services that they perceived they needed. There is a need to develop physiotherapy services in collaboration with people living with CP.Implications of rehabilitationAdults with cerebral palsy (CP) needed physiotherapy services, but were not receiving the physiotherapy services that they perceive they needed.Adults were not satisfied with the availability or quality of physiotherapy services received.Adults with scoliosis and mobility decline were less likely to report that they received the physiotherapy they needed.There is a need to develop physiotherapy services from a life-span perspective for adults living with CP.

Multicentre, randomised controlled feasibility study to compare a 10-week physiotherapy programme using an interactive exercise training device to improve walking and balance, to usual care of children with cerebral palsy aged 4-18 years: the ACCEPT study protocol

INTRODUCTION

Children with cerebral palsy (CP) frequently undertake physiotherapy programmes to improve walking and balance. They often require adult support to exercise in a functional position. A novel interactive exercise trainer has been devised to enable children to exercise with against resistance in a functional position, but its efficacy has yet to be proved. A novel protocol has been developed to determine whether a randomised controlled trial (RCT) is feasible.

AIM

To establish whether it is feasible to conduct an RCT to assess the effectiveness of a 10-week physiotherapy intervention using an interactive trainer in children with CP.

METHODS AND ANALYSIS

This study is multicentre randomised controlled feasibility trial with an embedded qualitative study. Forty children with CP, Gross Motor Function Classification System (GMFCS) I-III will be recruited from community paediatric physiotherapy caseloads. Participants will be randomised to 10 weeks of training with the interactive training device or to usual physiotherapy care. The mediolateral motion of the centre of mass estimate and Paediatric Balance Scale will be explored as potential primary outcomes measures, tested at baseline, 10 weeks and follow-up at 20 weeks. The views of child participants, their parents and physiotherapists will be gained through e-diaries and qualitative interviews.Feasibility will be determined by examining recruitment and retention rates, completeness of, adherence to the intervention, appropriateness of outcome measures and effectiveness of blinding. Results will be reported in accordance to Consolidated Standards of Reporting Trials (CONSORT) guidelines.

ETHICS AND DISSEMINATION

Physiotherapists, children and parents have informed trial design and information leaflets. Results will be disseminated via publications, conferences and to families. This study has approval from North of Scotland Research Ethics Committee (20/NS/0018).

Secondary Osteoporosis

Osteoporosis is a global public health problem, with fractures contributing to significant morbidity and mortality. Although postmenopausal osteoporosis is most common, up to 30% of postmenopausal women, > 50% of premenopausal women, and between 50% and 80% of men have secondary osteoporosis. Exclusion of secondary causes is important, as treatment of such patients often commences by treating the underlying condition. These are varied but often neglected, ranging from endocrine to chronic inflammatory and genetic conditions. General screening is recommended for all patients with osteoporosis, with advanced investigations reserved for premenopausal women and men aged < 50 years, for older patients in whom classical risk factors for osteoporosis are absent, and for all patients with the lowest bone mass (Z-score ≤ -2). The response of secondary osteoporosis to conventional anti-osteoporosis therapy may be inadequate if the underlying condition is unrecognized and untreated. Bone densitometry, using dual-energy x-ray absorptiometry, may underestimate fracture risk in some chronic diseases, including glucocorticoid-induced osteoporosis, type 2 diabetes, and obesity, and may overestimate fracture risk in others (eg, Turner syndrome). FRAX and trabecular bone score may provide additional information regarding fracture risk in secondary osteoporosis, but their use is limited to adults aged ≥ 40 years and ≥ 50 years, respectively. In addition, FRAX requires adjustment in some chronic conditions, such as glucocorticoid use, type 2 diabetes, and HIV. In most conditions, evidence for antiresorptive or anabolic therapy is limited to increases in bone mass. Current osteoporosis management guidelines also neglect secondary osteoporosis and these existing evidence gaps are discussed.

Falls and Associated Factors among Adolescents and Young Adults with Arthrogryposis Multiplex Congenita

Background:

Falls research among individuals with arthrogryposis multiplex congenita (AMC), a group of congenital conditions characterized by joint contractures in two or more body regions, is sparse. The primary objectives of this study were to estimate the prevalence of single, multiple, and injurious falls among adolescents and adults with AMC and identify factors associated with multiple and injurious falls.

Methods:

Individuals, aged 10–50 years, with a diagnosis of AMC completed questionnaires obtaining demographic and AMC-specific information, falls history (e.g., number, injurious/non-injurious), markers of bone health, orthopedic surgical history, and mobility aid use, as well as the Gillette Functional Assessment Questionnaire and the Saltin-Grimby Physical Activity Level Scale. Falls were defined as “any body part above the ankle coming to rest on the ground, floor, or a lower level”. Falling was defined as ≥ 1 fall, while multiple falls were defined as ≥ 2 falls in the past year.

Differences in falling, multiple falls, and injurious falls rates between adolescents (10–17 years) and adults (aged 18–50 years) were evaluated. Using univariate binary logistic regression models, associations between participant characteristics and multiple falls, as well as injurious falls, were evaluated, while considering age as a covariate (p ≤ 0.050); odds ratios (ORs) and 95% confidence intervals (CIs) were calculated.

Results:

Adolescents (N = 28; median age = 14 years) and adults (N = 40; median age = 32 years) with AMC had similar falling, i.e., 89.3% versus 70.0%, and injurious fall rates, i.e., 32.1% versus 27.5%, respectively (p > 0.050).

Adolescents with AMC, however, were more likely to report multiple falls in the past year, i.e., 89.3%, when compared to adults with AMC, i.e., 57.5% (p = 0.005). Beyond age, multiple falls were associated with a greater number of lower-limb surgeries [p = 0.036, OR (95%CI): 1.18 (1.01–1.39)], ability to transfer floor-to-stand with support [p = 0.002, OR (95%CI): 8.98 (2.30–35.06)], and increased mobility per the Gillette Functional Assessment Questionnaire [p = 0.004, OR (95%CI): 1.48 (1.13–1.92)]. Factors associated with a reduced odds of multiple falls were spinal involvement [p = 0.025, OR (95%CI): 0.23 (0.07–0.84)], history of spinal surgery [p = 0.018, OR (95%CI: 0.18 (0.04–0.74)], greater upper extremity involvement [OR (95%CI): 0.65 (0.44–0.95)], home assistive device use [p = 0.010, OR (95%CI): 0.15 (0.03–0.63)], and community wheelchair use [p = 0.006, OR (95%CI): 0.16 (0.04–0.59)]. None of the explored characteristics were associated with injurious falls in the past year (p > 0.050).

Conclusion:

Falls are exceedingly common among adolescents and adults with AMC; potential risk and protective factors for multiple falls are identified for future prospective falls research.

Perceived Limitations of Walking in Individuals With Cerebral Palsy

OBJECTIVE

Impairments associated with cerebral palsy (CP) can affect gait quality and limit activity and participation. The purpose of this study was to quantify (1) which of 6 factors (pain, weakness, endurance, mental ability, safety concerns, balance) were perceived to limit walking ability the most in individuals with CP and (2) whether age or Gross Motor Function Classification System (GMFCS) level is related to that perception.

METHODS

This cross-sectional study queried data from a gait laboratory database. Perceived walking limitation was quantified using a 5-point Likert scale ("never" to "all of the time"). Included were 1566 children and adults (mean age = 10.9 y [SD = 6.8]; range = 3.0-72.1 y) with CP (GMFCS level I: 502; II: 564; III: 433; IV: 67).

RESULTS

Patients or caregivers perceived balance to limit walking ability to the greatest extent, followed by endurance, weakness, safety, mental ability, and pain. Balance was perceived to always limit walking ability in 8%, 22%, 30%, and 34% of individuals in GMFCS levels I through IV, respectively. Endurance was perceived to always limit walking ability in 5%, 13%, 13%, and 27% of individuals in GMFCS levels I through IV, respectively. There were minor differences in the perceived extent of limitation caused by the factors by GMFCS level. Only weak associations between age and pain, mental ability, safety, and balance were observed (Spearman rho = -0.13 to 0.24).

CONCLUSION

Patients or caregivers perceived decreased balance and endurance to most strongly limit walking ability. Efforts should be made to clinically track how both perceived and objective measures of these limiting factors change with age and intervention.

IMPACT

Following a patient- and family-centered care model, therapy that places greater emphasis on balance and cardiovascular endurance may have the greatest effect on walking ability for individuals with CP. Future research should quantify which therapeutic, surgical, and pharmacologic interventions minimize these impairments and optimize activity and participation.

LAY SUMMARY

Balance and endurance are perceived to be the greatest factors limiting walking in people with CP. If you have CP, your physical therapist might emphasize balance and cardiovascular endurance to improve your walking ability.

Dynamic and static stability in para-athletes with cerebral palsy considering their impairment profile

BACKGROUND

Balance impairment is a common feature in people with cerebral palsy (CP), affecting the performance of daily-life and physical activities.

OBJECTIVES

To (1) explore the absolute and relative intrasession reliability of two balance tests to assess dynamic and static balance in ambulant para-athletes with CP; (2) explore the relationships between the two balance tests to determine potential application in sport classification; (3) assess the differences between CP profiles (ie, spastic diplegia, athetosis/ataxia, and spastic hemiplegia) in comparison to those with a minimum impairment; and (4) compare the outcomes of the static and dynamic balance of ambulant para-athletes with CP regarding controls.

METHODS

A group of 129 male well-trained para-footballers with CP, classified as Level I according to the Gross Motor Function Classification System, participated in the present study. Static balance was assessed using the One-Leg Stance test, performed bilaterally on a force platform, and the dynamic balance was assessed in two conditions of the Tandem Walk test (TW): walking heel-toe contact over a 5 -m straight line and performing 10 steps.

RESULTS

Moderate-to-excellent intrasession reliability (intraclass correlation coefficient = 0.60-0.98) was obtained for all the measurements and groups. However, only small to moderate correlations were found between the dynamic and the static measurements of balance for the CP group when performing the One-Leg Stance test with the unimpaired or dominant leg (0.23 < r < 0.30; P < .01). The TW performed over 10 steps revealed more sensitivity to discriminate between CP profiles. Those para-athletes with ataxia/athetosis performed worse in all the tests whereas all CP profiles performed worse than the control group (P < .01).

CONCLUSIONS

Balance performance and postural control are constrained to a higher extent in those with impaired voluntary control due to ataxia or with involuntary contractions of the muscles due to athetosis.

The effect of dual-task conditions on gait and balance performance in children with cerebral palsy: A systematic review and meta-analysis of observational studies

Dual-task conditions are commonly experienced in daily routines. The aim of the present systematic review is to investigate the effect of dual-task conditions on gait and balance performance in children with cerebral palsy (CP) and to perform meta-analyses where applicable. Five databases, "ProQuest", "PubMed", "OTSeeker", "Scopus", and "PEDro" from the incipient date of databases up to Aug 24, 2020 were searched for studies focusing on the effects of dual-task conditions on gait and balance performance in children with CP. After removing irrelevant articles and applying inclusion and exclusion criteria, nine articles were included in the present systematic review and meta-analysis. The results of the meta-analysis showed that walking speed was slower during dual-task conditions compared to single-task conditions in children with CP (WMD = -0.29 m/s, 95% CI = -0.34, -0.24, P ≤ 0.001) and walking speed decreased in children with CP during dual-task conditions in comparison with the typical development (TD) control group (WMD = -0.19 m/s, 95% CI = -0.23 to -0.15, P ≤ 0.001). The results of subgroup analysis based on the type of task indicated that adding concurrent tasks to walking degrades walking speed under varied dual-task conditions. Additionally, theoretical synthesis of the literature demonstrated that other gait and balance variables are changed by performing cognitive and motor secondary tasks differently. Although these changes may be compensatory strategies to retain their stability, there was not sufficient evidence to reach a firm conclusion. Research gaps and recommendations for future studies are discussed.

Sit-to-stand movement in childrenwith cerebral palsy and relationships with the International classification of functioning, disability and health: A systematic review

BACKGROUND

Studying sit-to-stand (STS) in children with Cerebral Palsy addressing the domains of ICF allows determining the factors influencing STS in this population.

AIMS

To systematically review the literature on STS in children with CP, identifying which ICF domains have been assessed and how they relate to sit-to-stand.

METHODS AND PROCEDURES

A literature search was conducted in electronic databases by combining the keywords (child OR children OR adolescent) AND ("Cerebral Palsy") AND (sit-to-stand). We included cross-sectional articles published in English, that assessed STS movements in children with CP up to 18 years old.

OUTCOMES AND RESULTS

25 articles met the inclusion criteria. All of them assessed Body Functions and Structure. According to them, body alignment, muscle strength and postural sway affect STS movement. Six studies related Activity and Participation with STS, demonstrating that worse scores in scales that evaluate activities and participation are related to the poorer STS execution. Contextual factors were addressed in 15 studies: children's age, bench height, manipulation of sensory information and mechanical restriction impact the way children execute STS.

CONCLUSION AND IMPLICATIONS

Contextual factors and Body Functions and Structure impact the STS in children with CP. However, few studies have evaluated the participation of these children. Based on the theoretical framework of the ICF, it is important that future studies evaluate functional tasks in children with CP and the components that can affect them. The adoption of the biopsychosocial model strengthens the understanding of functioning, which can contribute to rehabilitation planning.

Web-based home-hazard modification app for falls prevention: the views of those at risk of falling and their carers

Purpose

The purpose of the study is to assess the usability and acceptability of FallCheck, a Web app that allows users to complete home-hazard assessments within their own home, with a group of people at risk of falling and their carers.

Design/methodology/approach

This mixed method study used an online survey followed by semi-structured telephone interviews to collect both qualitative and quantitative data. A Think-Aloud study was used to test usability of the Web app through structured tasks.

Findings

Findings showed that FallCheck was easy to use with few usability issues. The Web app was deemed appropriate to use by people at risk of falling (young or old) or by carers if appropriate. The depth of knowledge provision and breadth of content was acceptable, and many participants reported subsequently making changes to their home environment to reduce their risk of falling. Overall, the majority of participants reported feelings of improved confidence and safety with an increased awareness of fall risks and a reduction in fear of falling at home.

Practical implications

FallCheck has good acceptability and usability with people at risk of falling and their carers and has the potential to improve access to home-hazard assessment and affect behavioural change regarding fall risk hazards and behaviour.

Originality/value

This study describes successful use of an app that may be helpful in identifying home-hazards and making changes to reduce risk of falls, particularly in the absence of occupational therapy intervention and has the potential for integration into falls care pathways.

A Mindfulness-Based Stress Reduction Program via Group Video Conferencing for Adults With Cerebral Palsy - A Pilot Study

Purpose: Adults with cerebral palsy experience challenges related to lifelong disability, such as stress, fatigue, pain and emotional issues. E-health services can be delivered regardless of residence and level of functioning. The aim of this pilot study was to explore the potential benefits and feasibility of a mindfulness-based program delivered to adults with cerebral palsy via group video conferencing.

Methods: Six adults with cerebral palsy received an 8 week mindfulness group-based program via video conferencing. A multiple single-case study design was applied, including quantitative and qualitative elements. Pain was assessed 16 times through the study period. Questionnaires were administered to gather data on pain catastrophizing, stress, fatigue, emotional distress, positive and negative affect, and quality of life. A focus group interview addressed experiences with the intervention and the mode of delivery.

Results: The participants' pain levels showed varied trajectories. Pain catastrophizing and negative affect were statistically significant decreased. Qualitative data indicated benefits from mindfulness in coping and stress management. The video conferencing delivery was evaluated as feasible, with no major adverse effects.

Conclusion: Since the pilot study had a small sample size, potential treatment benefits should be interpreted with caution. However, this pilot study provides important information in the planning of future larger and controlled studies on mindfulness-based interventions programs via video conferencing for adults with cerebral palsy and other persons living with long-term disability.

Incidence of falls among adults with cerebral palsy: a cohort study using primary care data

AIM

To compare the rate of falls between adults with and without cerebral palsy (CP).

METHOD

We used primary care data on 1705 adults with CP and 5115 adults without CP matched for age, sex, and general practice attended. We compared odds of experiencing a fall between adults with and without CP using conditional logistic regression. We compared the rate of falls using a negative binomial model.

RESULTS

Participants were 3628 males (53%) and 3192 females (47%) (median age 29y, interquartile range 20-42y) at the start of follow-up. Follow-up was 14 617 person-years for adults with CP and 56 816 person-years for adults without CP. Of adults with CP, 15.3% experienced at least one fall compared to 5.7% of adults without CP. Adults with CP had 3.64 times (95% confidence interval [CI] 2.98-4.45) the odds of experiencing a fall compared to adults without CP. The rate of falls was 30.5 per 1000 person-years and 6.7 per 1000 person-years for adults with and without CP respectively (rate ratio 5.83, 95% CI 4.84-7.02) INTERPRETATION: Adults with CP are more likely to fall, and fall more often, than adults without CP. The causes and consequences of falls in adults with CP need examination.

WHAT THIS PAPER ADDS

Twenty adults with CP and 5.3 adults without CP experienced at least one fall per 1000 person-years. Adults with CP experienced 30.5 falls per 1000 person-years compared to 6.7 falls per 1000 person-years among adults without CP. Adults with CP had 3.64 times the odds of experiencing a fall compared to adults without CP. Adults with CP experienced 5.83 times more falls than adults without CP.

A systematic review of vestibular stimulation in cerebral palsy

PURPOSE

Identify the types and dosage of vestibular stimulation interventions in persons with cerebral palsy (CP), and establish the efficacy of these interventions on balance and function.

MATERIALS AND METHODS

This systematic review followed Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols to search for studies evaluating vestibular stimulation interventions in persons with CP. Information sources included MEDLINE, Embase, CINAHL, Cochrane Central Register of Controlled Trials, clinicaltrials.gov and the World Health Organisation registry. Methodological quality was assessed by two independent reviewers using the Methodological Index of Non-Randomised Studies (MINORS) and Cochrane Risk of Bias Tool.

RESULTS

Five articles were included. Three randomised studies were judged to have high risk of bias in at least one domain of the Cochrane Risk of Bias Tool. Two non-randomised studies were rated as low methodological quality using the MINORS tool. All studies used exercise-based vestibular stimulation, but there was little homogeneity regarding dosage. Findings related to efficacy of vestibular stimulation were inconsistent.

CONCLUSIONS

Clinical practice recommendations cannot be made due to lack of high quality studies and heterogeneity of treatment protocols. Future research should address theory-driven selection of intervention, establish dosage, use psychometrically robust tools and include all ages of persons with CP.IMPLICATIONS FOR REHABILITATIONOptimal intervention parameters for vestibular stimulation cannot be determined from existing literature.Further studies to describe vestibular stimulation intervention components and duration are warranted.In practice, use of valid and reliable balance and gross motor function outcome measures are essential if using vestibular stimulation techniques with people with CP, as the efficacy of these interventions has not been clearly demonstrated.Investigation of electrical Vestibular Nerve Stimulation in people with CP is warranted.

Experienced complaints, activity limitations and loss of motor capacities in patients with pure hereditary spastic paraplegia: a web-based survey in the Netherlands

Background

Hereditary spastic paraplegia (HSP) is a group of inherited disorders characterized by progressive spastic paresis of the lower limbs. Treatment is often focused on reducing spasticity and its physical consequences. To better address individual patients’ needs, we investigated a broad range of experienced complaints, activity limitations, and loss of motor capacities in pure HSP. In addition, we aimed to identify patient characteristics that are associated with increased fall risk and/or reduced walking capacity.

Methods

We developed and distributed an HSP-specific online questionnaire in the Netherlands. A total of 109 out of 166 questionnaires returned by participants with pure HSP were analyzed.

Results

Participants experienced the greatest burden from muscle stiffness and limited standing and walking activities, while 72% reported leg and/or back pain. Thirty-five and 46% reported to use walking aids (e.g. crutches) indoors and outdoors, respectively; 57% reported a fall incidence of at least twice a year (‘fallers’); in 51% a fall had led to an injury at least once; and 73% reported fear of falling. Duration of spasticity and incapacity to rise from the floor were positively associated with being a ‘faller’, whereas non-neurological comorbidity and wheelchair use were negatively associated. Higher age, experienced gait problems, not being able to stand for 10 min, and incapacity to open a heavy door showed a negative association with being a ‘walker without aids’ (> 500 m).

Conclusions

Our results emphasize the large impact of spastic paraparesis on the lives of people with pure HSP and contribute to a better understanding of possible targets for rehabilitation.

Pain in adults with cerebral palsy: A systematic review and meta-analysis of individual participant data

BACKGROUND

There is little focus on adults with cerebral palsy (CP) in research and health care and insufficient knowledge on how to identify and manage pain in this population.

OBJECTIVES

This systematic review and meta-analysis aimed to determine whether pain prevalence in adults with CP is high and to explore variations in pain prevalence of subgroups, pain locations, pain severity and pain interference.

METHODS

Potential datasets were identified by experts in the field and literature searches in Embase, MEDLINE, and Cochrane, from January 2000 to October 2016. Included studies had a representative sample of ≥25 adults with CP and ≥1 pain outcomes. Methodological quality assessment, pain prevalence estimates and logistic regression models for subgroup effects on pain prevalence were conducted.

RESULTS

In total, 17 eligible studies were identified from 4584 publications. A meta-analysis was performed with individual participant data from 15 studies totalling 1243 participants (mean [SD] age 34.3 [12.6] years). Overall mean pain prevalence was 70% (95% CI 62-78). Women were more likely to have pain than men (P<0.001). The odds of pain was increased in adults with gross motor function level II (odds ratio [OR] 1.92, 95% CI 1.22-3.12) and IV (OR 1.77, 95% CI 1.03-4.29). Participants with pain reported pain predominantly in the legs (76%, 95% CI 66-84), and mean pain severity was 3.7/10 (95% CI 2.7-4.7) and pain interference 3.5/10 (95% CI 2.5-4.5).

CONCLUSIONS

This meta-analysis provides the first reliable pain prevalence estimate in a large international sample of adults with CP. The high prevalence of pain, 70%, suggests that adults with CP should be routinely screened for pain and treated accordingly. The range of measurement instruments used by the included studies emphasizes using common outcome measures specific to pain internationally.

Epidemiology of Cerebral Palsy in Adulthood: A Systematic Review and Meta-analysis of the Most Frequently Studied Outcomes

OBJECTIVE

To describe the epidemiology of health status, impairments, activities and participation in adults with cerebral palsy (CP).

DATA SOURCES

Embase, MEDLINE, Web of Science, PsycINFO, Cumulative Index to Nursing and Allied Health, Cochrane, and Google Scholar were searched for 3 themes ("cerebral palsy," "adult," and "outcome assessment") in literature published between January 2000 and December 2018.

STUDY SELECTION

Full-article peer-reviewed English journal articles on descriptive, observational, or experimental studies describing the most studied outcomes in adults with CP (n≥25, age≥18y) were included. Studies were included in the analyses if frequently studied outcomes were described in at least 3 studies using similar methods of assessment.

DATA EXTRACTION

Data were extracted independently by 2 authors from 65 articles (total N=28,429) using a standardized score sheet.

DATA SYNTHESIS

Meta-analyses revealed that overall, on average 65.1% (95% confidence interval [CI], 55.1-74.5) of adults with CP experienced pain, 57.9% (95% CI, 51.1-64.6) were ambulant, 65.5% (95% CI, 61.2-69.7) had little or no limitation in manual ability, 18.2% (95% CI, 10.6-27.2) had tertiary education, 39.2% (95% CI, 31.5;47.1) were employed, and 29.3% (95% CI, 9.0-55.3) lived independently. In adults without intellectual disability, proportions of individuals who were ambulant (72.6% [95% CI, 58.8-84.5]) and lived independently (90.0% [95% CI, 83.8-94.9]) were higher (P=.014 and P<.01, respectively). The Fatigue Severity Scale score was 4.1 (95% CI, 3.8-4.4). Epilepsy (28.8% [95% CI, 20.1-38.4]) and asthma (28.3% [95% CI, 18.7-38.9]) were especially prevalent comorbidities.

CONCLUSIONS

The present systematic review and meta-analysis on the epidemiology of adults with CP provided state-of-the-art knowledge on the most frequently studied outcomes. On average, adults with CP are fatigued, and a majority experience pain, are ambulant, and have little or no difficulty with manual ability. On average, 40% are employed and 30% live independently. More uniformity in assessment and reports is advised to improve knowledge on epidemiology and gain insight in more outcomes.

Novel approaches to measuring community integration in adults with cerebral palsy

Purpose: Rehabilitation goals often focus on increasing community integration for adults with disabilities and are measured by objective assessments. Research methods have lagged behind in capturing current conceptualizations of community integration as a multidimensional construct that incorporates participation, social supports, and feelings of belonging in the community. This paper addresses this challenge by describing a multi-method approach to assessing community integration for adults with cerebral palsy.Methods: Measures include standardized questionnaires, qualitative methods, measures of function and physical activity, and geospatial measures using Geographic Information System mapping and Global Positioning System tracking. These objective and subjective data are used to determine where adults spend time and are most active, and which activities and social connections are associated with feeling integrated into the community.Results: Two case examples highlight the importance of using a multi-method approach to assess community integration for adults with cerebral palsy. Results of objective clinical measures were comparable among case examples; however, actual experiences of feeling connected to the community were vastly different.Conclusions: Multiple measures are required to capture the complexity of community integration. Relying solely on objective measures may not provide a complete picture of community integration.IMPLICATIONS FOR REHABILITATIONCommunity integration is a complex construct that incorporates participation, socialization, and feelings of belonging in the community.New methods and measures are needed to assess the many aspects of community integration in adults with disabilities.A multi-method approach is recommended to provide a richer characterization of community integration in individuals with disabilities.A combination of quantitative and qualitative measures addressing the physical, social and psychological aspects of community integration should be used.

Mobility related physical and functional losses due to aging and disease - a motivation for lower limb exoskeletons

BACKGROUND

Physical and functional losses due to aging and diseases decrease human mobility, independence, and quality of life. This study is aimed at summarizing and quantifying these losses in order to motivate solutions to overcome them with a special focus on the possibilities by using lower limb exoskeletons.

METHODS

A narrative literature review was performed to determine a broad range of mobility-related physical and functional measures that are affected by aging and selected cardiovascular, respiratory, musculoskeletal, and neurological diseases.

RESULTS

The study identified that decreases in limb maximum muscle force and power (33% and 49%, respectively, 25-75 yrs) and in maximum oxygen consumption (40%, 20-80 yrs) occur for older adults compared to young adults. Reaction times more than double (18-90 yrs) and losses in the visual, vestibular, and somatosensory systems were reported. Additionally, we found decreases in steps per day (75%, 60-85 yrs), maximum walking speed (24% 25-75 yrs), and maximum six-minute and self-selected walking speed (38% and 21%, respectively, 20-85 yrs), while we found increases in the number of falls relative to the number of steps per day (800%), injuries due to falls (472%, 30-90 yrs) and deaths caused by fall (4000%, 65-90 yrs). Measures were identified to be worse for individuals with impaired mobility. Additional detrimental effects identified for them were the loss of upright standing and locomotion, freezing in movement, joint stress, pain, and changes in gait patterns.

DISCUSSION

This review shows that aging and chronic conditions result in wide-ranging losses in physical and sensory capabilities. While the impact of these losses are relatively modest for level walking, they become limiting during more demanding tasks such as walking on inclined ground, climbing stairs, or walking over longer periods, and especially when coupled with a debilitating disease. As the physical and functional parameters are closely related, we believe that lost functional capabilities can be indirectly improved by training of the physical capabilities. However, assistive devices can supplement the lost functional capabilities directly by compensating for losses with propulsion, weight support, and balance support.

CONCLUSIONS

Exoskeletons are a new generation of assistive devices that have the potential to provide both, training capabilities and functional compensation, to enhance human mobility.

Gait pathology subtypes are not associated with self-reported fall frequency in children with cerebral palsy

BACKGROUND

Trips and falls are common concerns reported by parents of children with cerebral palsy. Specific gait pathologies (excessive internal hip rotation, intoeing, and stiff knee gait) are anecdotally associated with higher rates of falls.

RESEARCH QUESTION

Is fall frequency higher for the aforementioned gait pathologies?

METHODS

Parent-reported fall frequency from 1063 children with cerebral palsy who also had a three-dimensional gait analysis was retrospectively reviewed. Frequency of 10 common gait pathologies was determined and fall frequency for the gait pathologies of interest were compared to matched control groups. Possible effects of Gross Motor Functional Classification System (GMFCS) level and age on fall frequency were also assessed and matched in the control group, as appropriate.

RESULTS

In general, parent-reported fall frequency increased from GMFCS level I to II and then decreased until level IV. Moreover, younger children tended to report greater fall frequency, though children who reported never falling were of similar age as those who reported weekly falls, resulting in an inverted-U shaped relationship. Children with cerebral palsy who walked with excessive internal hip rotation, excessive intoeing, or stiff knee gait did not report increased fall frequencies compared to other children with cerebral palsy matched on GMFCS level and age that did not walk with those gait patterns. Approximately 35% of children reported never falling, 35% reported falling daily, and 30% reported falling monthly or weekly for each gait pattern. Therefore, elevated fall frequency appears to be a generic problem for most children with CP rather than a function of a specific gait pattern.

SIGNIFICANCE

Clinicians should be aware of these relationships, or lack thereof, when trying to decipher the cause of a child's falling and when determining appropriate interventions. Future studies may seek to more objectively quantify fall frequency, as self-report is the main limitation of this study.

Long-term impact of childhood selective dorsal rhizotomy on pain, fatigue, and function: a case-control study

AIM

Selective dorsal rhizotomy (SDR) is a surgical treatment for spasticity in children with cerebral palsy (CP). Studies suggest long-lasting effects of SDR on spasticity; long-term effects on symptoms and function are not clear. This study tested whether adults with CP (average 22y after SDR) report less pain, fatigue, and functional decline than a retrospectively assessed non-surgical comparison group.

METHOD

This was a case-control study. Eighty-eight adults with CP (mean age 27y; SDR=38 male/female/missing=20/16/2; non-surgical [comparison]=50, male/female=19/31) recruited from a tertiary care center and the community completed a battery of self-reported outcome measures. Regression models were used to test whether SDR status predicted pain, fatigue, functional change, and hours of assistance (controlling for Gross Motor Function Classification System level).

RESULTS

SDR status did not significantly predict pain interference (p=0.965), pain intensity (p=0.512), or fatigue (p=0.404). SDR related to lower decline in gross motor functioning (p=0.010) and approximately 6 fewer hours of daily assistance than for those in the comparison group (p=0.001).

INTERPRETATION

Adults with CP who had SDR in childhood reported less gross motor decline and fewer daily assistance needs than non-surgically treated peers, suggesting the functional impact of SDR persists long after surgery.

Predictive Factors for Inpatient Falls among Children with Cerebral Palsy

OBJECTIVE

Inpatient falls are of significant concern. The aim of this prospective study was to determine the predictors of inpatient falls among children with cerebral palsy in a rehabilitation hospital.

DESIGN AND METHODS

A total of 93 patients with cerebral palsy were assessed based on history, physical findings, the Selective Motor Control Test, the Gross Motor Functional Classification System, the Berg Balance Scale and the Manual Ability Classification System. Previous history of falls/frequent falls, and any falls which occurred during hospitalization, were recorded.

RESULTS

Of all 93 patients, 25 (27%) fell and 68 (73%) did not fall. The mean age of the fallers (6.3±2.0 years) was lower than that of the non-fallers (8.1±3.9 years). Behavioral problems according to the mother's statement (OR 26.454), not being able to maintain a long sitting position (OR 10.807), ability to balance on knees without support (OR 9.810), a history of frequent falls (OR 4.893) and a negative Thomas test (OR 4.192 fold) were found to increase the risk of inpatient falls.

CONCLUSIONS

In these children with cerebral palsy, behavioral problems according to the mother's statement, a history of frequent falls, not being able to maintain a long sitting position, a negative Thomas test, and able to balance on knees without support were associated with the risk of inpatient falls. Children with cerebral palsy may experience inpatient falls. Further studies are required in order to develop prevention programs.

PRACTICE IMPLICATIONS

For patients diagnosed with cerebral palsy, these results may help identify possible inpatient fallers on hospital admission.

Systematic review of whole body vibration exercises in the treatment of cerebral palsy: Brief report

OBJECTIVE

Whole body vibration (WBV) is increasingly being used to improve balance and motor function and reduce the secondary complications associated with cerebral palsy (CP). The purpose of this study was to systematically appraise published research regarding the effects of static and/or dynamic exercise performed on a vibrating platform on gait, strength, spasticity and bone mineral density (BMD) within this population.

METHODS

Systematic searches of six electronic databases identified five studies that met our inclusion criteria (2 at Level II and 3 at Level III-2). Studies were analysed to determine: (a) participant characteristics; (b) optimal exercise and WBV treatment protocol; (c) effect on gait, strength, spasticity and BMD; and (d) the outcome measures used to evaluate effect. As data was not homogenous a meta-analysis was not possible.

RESULTS

Several design limitations were identified and intervention protocols are poorly described. The effects on strength, gait, spasticity and BMD in persons with CP remain inconclusive with weak evidence that WBV may improve selected muscle strength and gait parameters and that prolonged exposure may improve BMD; there is currently no evidence that WBV can reduce spasticity.

CONCLUSIONS

The evidence for exercise performed on a vibrating platform on mobility, strength, spasticity and BMD in CP remains scant and further larger scale investigations with controlled parameters to better understand the effects of WBV exercises in this population is recommended.

Gait characteristics, balance performance and falls in ambulant adults with cerebral palsy: An observational study

The relationship between spatiotemporal gait parameters, balance performance and falls history was investigated in ambulant adults with cerebral palsy (CP). Participants completed a single assessment of gait using an instrumented walkway at preferred and fast speeds, balance testing (Balance Evaluation Systems Test; BESTest), and reported falls history. Seventeen ambulatory adults with CP, mean age 37 years, participated. Gait speed was typically slow at both preferred and fast speeds (mean 0.97 and 1.21m/s, respectively), with short stride length and high cadence relative to speed. There was a significant, large positive relationship between preferred gait speed and BESTest total score (ρ=0.573; p<0.05) and fast gait speed and BESTest total score (ρ=0.647, p<0.01). The stride lengths of fallers at both preferred and fast speeds differed significantly from non-fallers (p=0.032 and p=0.025, respectively), with those with a prior history of falls taking shorter strides. Faster gait speed was associated with better performance on tests of anticipatory and postural response components of the BESTest, suggesting potential therapeutic training targets to address either gait speed or balance performance. Future exploration of the implications of slow walking speed and reduced stride length on falls and community engagement, and the potential prognostic value of stride length on identifying falls risk is recommended.

Perceived cause, environmental factors, and consequences of falls in adults with cerebral palsy: a preliminary mixed methods study

Objective. Describe perceived cause, environmental influences, and consequences of falls or near-falls in ambulant adults with cerebral palsy (CP). Methods. Adults with CP completed postal surveys and follow-up semistructured interviews. Surveys sought information on demographic data, self-nominated Gross Motor Function Classification Score (GMFCS-E&R), falls, and near-falls. Interviews gathered additional information on falls experiences, near-falls, and physical and psychosocial consequences. Results. Thirty-four adults with CP participated. Thirty-three participants reported at least one fall in the previous year. Twenty-six participants reported near-falls. Most commonly, falls occurred indoors, at home, and whilst engaged in nonhazardous ambulation. Adults with CP experienced adverse falls consequences, lower limb injuries predominant (37%), and descriptions of fear, embarrassment, powerlessness, and isolation. Discussion. Adults with CP may experience injurious falls. Further investigation into the impact of falls on health-related quality of life and effective remediation strategies is warranted to provide comprehensive falls prevention programs for this population.

Do children with cerebral palsy change their gait when walking over uneven ground?

Independently ambulant children with Cerebral Palsy (CP) often report balance difficulties when walking in challenging settings. The aim of this study was to compare gait in children with CP to typically developing (TD) children walking over level ground and uneven ground, as an evaluation of dynamic balance. Thirty-four children participated, 17 with CP (10 hemiplegia and 7 diplegia, mean age 10 years) and 17 TD (mean age 10 years 1 month). Three-dimensional kinematic and kinetic data of the lower limbs and trunk were captured during walking over level and uneven ground using Codamotion®. Statistical analysis was performed using a mixed-effects model two-factor Analysis of Variance (Group×Surface). Over both surfaces, children with CP showed increased trunk movement in the sagittal (Group effect, p<0.001) and transverse planes (p<0.001), and increased pelvic movement in the coronal plane (p=0.008), indicating impaired trunk control. Peak separation between the centre of mass and centre of pressure was reduced in CP, indicating impaired dynamic balance (p=0.027). TD children made a number of significant adaptations to uneven ground, including reduced hip extension (mean difference 3.4°, 95% CI [-5.3, -1.0] p=0.006), and reduced ankle movement in the sagittal (5.2°, 95% CI [0.01, 10] p=0.049) and coronal planes (2.4°, 95% CI [0.3, 4.5], p=0.029), but these adaptations were not measured in CP. A significant Group×Surface interaction was detected for knee sagittal range (p=0.009). The findings indicate that children with CP walk show impaired control of trunk movement and are less able to adapt their gait to uneven ground, particularly at the ankle.

Examination of the use of a dual-channel functional electrical stimulation system on gait, balance and balance confidence of an adult with spastic diplegic cerebral palsy

The purpose of this case report is to determine the effects of a dual-channel functional electrical stimulation (FES) system on gait and balance of a 57-year-old male diagnosed with spastic diplegic cerebral palsy (CP). Outcome measures included the: Activities-specific Balance Confidence Scale (ABC); Dynamic Gait Index (DGI); Observational Gait Scale (OGS) and Tinetti Performance Oriented Mobility Assessment (POMA). Assessments were completed with and without use of FES during the initial examination and after two, four and six weeks of intervention with FES. ABC Scale scores improved from 32.8 to 48.1% during the 6-week intervention. Scores on the DGI improved from 6/24 to 9/24 without FES and from 9/24 to 14/24 with FES. OGS scores improved on both legs with and without FES. Tinetti POMA scores improved from 12/28 to 15/28 without FES and decreased from 16/28 to 15/28 with FES. The patient demonstrated improvement in both objective and subjective measures. The use of FES facilitated improved gait and balance; however, the patient was still at increased risk for falls after the 6-week intervention despite improved scores on the ABC Scale, DGI, OGS and Tinetti POMA.

The safety and feasibility of an intervention to improve balance dysfunction in ambulant adults with cerebral palsy: a pilot randomized controlled trial

Objective:

To investigate the safety, feasibility and potential efficacy of balance training in adults with cerebral palsy.

Design:

Phase 2, assessor-blinded randomized controlled trial.

Setting:

Outpatient rehabilitation facility.

Subjects:

A total of 17 ambulatory adults with cerebral palsy.

Interventions:

Participants were randomly allocated to an eight-week, once-weekly, small group programme of balance training, or seated attention control activity. Balance training was individually tailored using the Balance Evaluation Systems test.

Main measures:

Primary focus was feasibility, addressed by recruitment, retention, adherence, and safety. Efficacy was primarily evaluated with the Ambulatory Self-Confidence Questionnaire and the Balance Evaluation Systems test, at intervention conclusion and Week 24. Secondary outcomes included gait speed, walking distance, falls efficacy, fatigue, quality of life, and global impression of change.

Results:

Interventions were safe and feasible with no major adverse events. Adherence was high. At eight and 24 weeks, there were negligible between-group differences in Balance Evaluation systems test total. At 24 weeks, there was a small, non-significant between-group difference in favour of the balance group with effect sizes of 0.14 for ambulatory self-confidence, 0.10 for falls efficacy, and 0.12 for fatigue. There were significant between-group differences for self-reported walking confidence and balance change, in favour of the balance group at Weeks 8 and 24 ( p < 0.05).

Conclusion:

A customised balance programme is feasible and safe for ambulant adults with cerebral palsy. Small effects from balance training in selected outcomes occurred. Study replication with at least 38 participants per group to confirm efficacy is warranted.

Health-related quality of life of ambulant adults with cerebral palsy and its association with falls and mobility decline: a preliminary cross sectional study

Background

Despite an increasing number of studies examining the profile of falls and mobility decline in adults with cerebral palsy (CP), little is known about its impact on an individual’s life quality. The aim of this preliminary study was to assess the wellbeing and health status aspects of health-related quality of life (HRQOL) in ambulant adults with CP and explore the relationship of falls and mobility decline with HRQOL.

Method

Ambulant adults with CP completed postal surveys which sought demographic data, mobility (Gross Motor Function Classification System; GMFCS-E&R), presence of mobility decline, falls history, and HRQOL (Personal Wellbeing Index (PWI), Short Form-36 Health Survey (SF-36)).

Results

Thirty-four community-dwelling ambulant adults with CP with a mean age of 44.2 years (SD; 8.6; range 26–65) participated. Twenty-eight (82%) participants reported mobility decline since reaching adulthood, and a similar proportion of individuals (82%) reported having had more than two falls in the previous year. The health status and wellbeing of this sample of ambulant adults with CP were generally lower compared with the Australian normative population. Mobility decline was found by univariate regression analysis to be associated with mental health status (β = 0.52; p = 0.002), but not when other predictor variables were included in the multivariate model (β = 0.27; p = 0.072). In contrast, self-reported history of falls was found to be a significant contributing factor for both physical health status (β = −0.55; p = 0.002) and personal wellbeing (β = −0.43; p = 0.006).

Conclusions

This sample of ambulant adults with CP perceived their HRQOL to be poor, with some health status and wellbeing domains below that of population wide comparisons. A majority of these individuals also experienced a fall in the last year and a decline in their mobility since reaching adulthood. While further research is required, this preliminary study has highlighted the potential implications of falls and mobility decline on HRQOL in adults with CP.
