The Better By Moving study: A multifaceted intervention to improve physical activity in adults during hospital stay

Objective

‘Better By Moving’ is a multifaceted intervention developed and implemented in collaboration with patients and healthcare professionals to improve physical activity in hospitalized adults. This study aimed to understand if, how and why ‘Better By Moving’ resulted in higher levels of physical activity by evaluating both outcomes and implementation process.

Design

Mixed-methods study informed by the Medical Research Council guidance.

Setting

Tertiary hospital.

Participants

Adult patients admitted to surgery, haematology, infectious diseases and cardiology wards, and healthcare professionals.

Measures

Physical activity was evaluated before and after implementation using the Physical Activity Monitor AM400 on one random day during hospital stay between 8 am and 8 pm. Furthermore, the time spent lying on bed, length of stay and discharge destination was investigated. The implementation process was evaluated using an audit trail, surveys and interviews.

Results

There was no significant difference observed in physical activity (median [IQR] 23 [12–51] vs 27 [17–55] minutes, P = 0.107) and secondary outcomes before-after implementation. The intervention components’ reach was moderate and adoption was low among patients and healthcare professionals. Patients indicated they perceived more encouragement from the environment and performed exercises more frequently, and healthcare professionals signalled increased awareness and confidence among colleagues. Support (priority, resources and involvement) was perceived a key contextual factor influencing the implementation and outcomes.

Conclusion

Although implementing ‘Better By Moving’ did not result in significant improvements in outcomes at our centre, the process evaluation yielded important insights that may improve the effectiveness of implementing multifaceted interventions aiming to improve physical activity during hospital stay.

The diagnostic accuracy of headache measurement instruments: A systematic review and meta-analysis focusing on headaches associated with musculoskeletal symptoms

AIM

To systematically review the available literature on the diagnostic accuracy of questionnaires and measurement instruments for headaches associated with musculoskeletal symptoms.

DESIGN

Articles were eligible for inclusion when the diagnostic accuracy (sensitivity/specificity) was established for measurement instruments for headaches associated with musculoskeletal symptoms in an adult population. The databases searched were PubMed (1966-2018), Cochrane (1898-2018) and Cinahl (1988-2018). Methodological quality was assessed with the Quality Assessment of Diagnostic Accuracy Studies tool (QUADAS-2) and COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist for criterion validity. When possible, a meta-analysis was performed. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) recommendations were applied to establish the level of evidence per measurement instrument.

RESULTS

From 3450 articles identified, 31 articles were included in this review. Eleven measurement instruments for migraine were identified, of which the ID-Migraine is recommended with a moderate level of evidence and a pooled sensitivity of 0.87 (95% CI: 0.85-0.89) and specificity of 0.75 (95% CI: 0.72-0.78). Six measurement instruments examined both migraine and tension-type headache and only the Headache Screening Questionnaire - Dutch version has a moderate level of evidence with a sensitivity of 0.69 (95% CI 0.55-0.80) and specificity of 0.90 (95% CI 0.77-0.96) for migraine, and a sensitivity of 0.36 (95% CI 0.21-0.54) and specificity of 0.86 (95% CI 0.74-0.92) for tension-type headache. For cervicogenic headache, only the cervical flexion rotation test was identified and had a very low level of evidence with a pooled sensitivity of 0.83 (95% CI 0.72-0.94) and specificity of 0.82 (95% CI 0.73-0.91).

DISCUSSION

The current review is the first to establish an overview of the diagnostic accuracy of measurement instruments for headaches associated with musculoskeletal factors. However, as most measurement instruments were validated in one study, pooling was not always possible. Risk of bias was a serious problem for most studies, decreasing the level of evidence. More research is needed to enhance the level of evidence for existing measurement instruments for multiple headaches.

Supporting Older Adults in Exercising With a Tablet: A Usability Study

Background

For older adults, physical activity is vital for maintaining their health and ability to live independently. Home-based programs can help them achieve the recommended exercise frequency. An application for a tablet computer was developed to support older adults in following a personal training program. It featured goal setting, tailoring, progress tracking, and remote feedback.

Objective

In line with the Medical Research Council Framework, which prescribes thorough testing before evaluating the efficacy with a randomized controlled trial, the aim of this study was to assess the usability of a tablet-based app that was designed to support older adults in doing exercises at home.

Methods

A total of 15 older adults, age ranging from 69 to 99 years old, participated in a usability study that utilized a mixed-methods approach. In a laboratory setting, novice users were asked to complete a series of tasks while verbalizing their ongoing thoughts. The tasks ranged from looking up information about exercises and executing them to tailoring a weekly exercise schedule. Performance errors and time-on-task were calculated as proxies of effective and efficient usage. Overall satisfaction was assessed with a posttest interview. All responses were analyzed independently by 2 researchers.

Results

The participants spent 13-85 seconds time-on-task. Moreover, 79% (11/14)-100% (14/14) participants completed the basic tasks with either no help or after having received 1 hint. For expert tasks, they needed a few more hints. During the posttest interview, the participants made 3 times more positive remarks about the app than negative remarks.

Conclusions

The app that was developed to support older adults in doing exercises at home is usable by the target audience. First-time users were able to perform basic tasks in an effective and efficient manner. In general, they were satisfied with the app. Tasks that were associated with behavior execution and evaluation were performed with ease. Complex tasks such as tailoring a personal training schedule needed more effort. Learning effects, usefulness, and long-term satisfaction will be investigated through longitudinal follow-up studies.

Translating Behavior Change Principles Into a Blended Exercise Intervention for Older Adults: Design Study

Background

Physical activity can prevent or delay age-related impairments and prolong the ability of older adults to live independently. Community-based programs typically offer classes where older adults can exercise only once a week under the guidance of an instructor. The health benefits of such programs vary. Exercise frequency and the duration of the program play a key role in realizing effectiveness. An auxiliary home-based exercise program can provide older adults the opportunity to exercise more regularly over a prolonged period of time in the convenience of their own homes. Furthermore, mobile electronic devices can be used to motivate and remotely guide older adults to exercise in a safe manner. Such a blended intervention, where technology is combined with personal guidance, needs to incorporate behavior change principles to ensure effectiveness.

Objective

The aim of this study was to identify theory-based components of a blended intervention that supports older adults to exercise at home.

Methods

The Medical Research Council framework was used to develop the blended intervention. Insights from focus group, expert panels, and literature were combined into leading design considerations.

Results

A client-server system had been developed that combined a tablet app with a database in the cloud and a Web-based dashboard that can be used by a personal coach to remotely monitor and guide older adults. The app contains several components that facilitate behavior change—an interactive module for goal setting, the ability to draw up a personal training schedule from a library containing over 50 exercise videos, progress monitoring, and possibilities to receive remote feedback and guidance of a personal coach.

Conclusions

An evidence-based blended intervention was designed to promote physical activity among older adults. The underlying design choices were underpinned by behavior change techniques that are rooted in self-regulation. Key components of the tablet-supported intervention were a tailored program that accommodates individual needs, demonstrations of functional exercises, monitoring, and remote feedback. The blended approach combines the convenience of a home-based exercise program for older adults with the strengths of mobile health and personal guidance.

Paediatric rehabilitation

More and more researchers are questioning the theoretical and scientific foundations as well as the efficacy and effects of many physiotherapy interventions. The same applies for many of the neurophysiological based interventions that are being used in paediatric rehabilitation. Opinions and views regarding the development of motor behaviour of infants and children are significantly changing. Paediatric interventionists should consider bringing their interventions and focus of treatment into agreement with changed scientific knowledge. Moreover, for almost all other medical problems in childhood, paediatric rehabilitation has little to offer but mostly miniaturized forms of adult treatment. It not only means that we have to make a paradigm shift, but also are in the need of a broader view on paediatric rehabilitation as a specialized professional activity.

Osteogenesis imperfecta in childhood: perceived competence in relation to impairment and disability

OBJECTIVES

To examine the perceived competence of children with different types of osteogenesis imperfecta (OI) and to investigate the possible relationships between their perceived competence and impairment parameters.

DESIGN

Cross-sectional study.

SETTING

National referral center (hospital) for the treatment of children with OI.

PATIENTS

Forty children with OI (type I = 17; type III = 11; type IV = 12) with a mean age +/- standard deviation of 12.6 +/- 3.2 years.

INTERVENTIONS

Measured joint range of motion (ROM) in the upper extremities (UEs), and lower extremities (LEs), muscle strength, functional skills, ambulation, and perceived competence.

MAIN OUTCOME MEASURES

Joint ROM in UE and LE; muscle strength (using the manual muscle testing criteria of the Medical Research Council); functional skills using the Pediatric Evaluation of Disability Inventory in 3 domains (self-care, mobility, social function). Ambulation (according to Bleck and classified as nonwalking, therapy walking, household walking, neighborhood walking, community walking with or without the use of crutches), and perceived competence (using the Harter Self-Perception Profile for Children, which was cross-culturally validated for Dutch children).

RESULTS

In children with type I, joint ROM and muscle strength were almost comparable to the healthy population. In children with type III, a severe decrease in joint ROM was measured, especially in the LEs, and muscle strength was severely decreased in the UEs and LEs. In children with type IV, joint ROM and muscle strength decreased, especially in the LEs. In all types, fairly to strongly positive perceived competence was measured except for fairly negative perceived competence in the athletic performance subscale in type I and a fairly negative perceived competence in the romance subscale in type III. No correlations were found between (1) joint ROM and athletic performance and physical appearance, (2) muscle strength and athletic performance or physical appearance, or (3) the functional skills, concerning self-care and mobility, with the subscales of the perceived competence.

CONCLUSIONS

Although joint ROM, muscle strength, and functional and walking ability were related to the severity of the disease and differed significantly between the different types of OI, overall perceived competence in children with OI was fairly to strongly positive, without significant differences between the different types of OI.

Osteogenesis imperfecta in childhood: prognosis for walking

OBJECTIVES

We studied the predicted value of disease-related characteristics for the ability of children with osteogenesis imperfecta (OI) to walk.

STUDY DESIGN

The severity of OI was classified according to Sillence. The parents were asked to report the age at which the child achieved motor milestones, the fracture incidence, and the age and localization of the first surgical intervention. The present main means of mobility was classified according to Bleck.

RESULTS

There were 76 replies to the 98 questionnaires, of which 70 were included (type I, 41; type III, 11; type IV, 18). The type of OI was strongly associated with current walking ability, as was the presence of dentinogenesis imperfecta. Patients with type III and IV had a lower chance of ultimately walking compared with those with type I. Children with more than 2 intramedullary rods in the lower extremities had a reduced chance of walking than patients without rods. Rolling over before 8 months, unsupported sitting before 9 months, the ability to get in sitting position without support before 12 months, and the ability to get in a standing position without support before 12 months showed positive odds ratios. In Bleck > or = 4, multivariate analysis revealed that only the presence of rodding (yes/no) in the lower extremities had additional predictive value to the type of OI. The presence of dentinogenesis imperfecta and rodding (yes/no) had additional value in Bleck > or = 5.

CONCLUSION

The type of OI is the single most important clinical indicator of the ultimate ability to walk. Information about motor development adds little. The early achievement of motor milestones contributes to the ability of independent walking when the type of OI is uncertain. Intramedullary rodding of the lower extremities is primarily related to the severity of the disease and in this way provides consequences for the ability to walk.

Osteogenesis imperfecta: profiles of motor development as assessed by a postal questionnaire

This study was performed to achieve more detailed information regarding the age and sequence in the development of motor milestones in the different types of osteogenesis imperfecta (OI). The parents of 98 patients with a diagnosis of OI were sent a questionnaire regarding the age at which patients achieved motor milestones. All patients were attending the outpatient clinic for children with OI at the Wilhelmina Children's Hospital. The motor milestones were classified into static motor milestones and dynamic motor milestones and all data were checked with health care records. The age of development of motor milestones was compared to reference values of the healthy population. The severity of the disease was classified according to Sillence based on clinical, genetic and radiological data. The age of intramedullary rodding of the first nail in the lower and upper extremity and the localisation was noted. A total of 76 parents responded to the 98 questionnaires (78%). In OI type I, a delay exists in achieving motor milestones, comparable to the 95th percentile of the normal population. In type III, the development of all motor milestones was significantly delayed compared to types I and IV with a discrepancy between static and dynamic milestones. In OI type IV, a retardation in motor development developed after the milestone 'sitting without support' was achieved. Motor development in types I and IV was not influenced by intramedullary rodding of the lower extremities, since rodding was rarely performed before the milestone 'unsupported standing' was achieved. In type III, the influence of intramedullary rodding on the age of achieving motor milestones remains questionable.

CONCLUSION

The severity of osteogenesis imperfecta has a large influence on the age and sequence in the development of motor milestones. No influence of intramedullary rodding of the lower extremities on motor development was found in osteogenesis imperfecta types I and IV, whereas the influence in type III remains questionable.

Osteogenesis imperfecta in childhood: impairment and disability--a follow-up study

OBJECTIVES

To evaluate differences over time (mean follow-up, 14 months) on impairment parameters (range of joint motion and muscle strength), functional limitation parameters (functional ability), and disability parameters (caregiver assistance in achieving functional skills) in osteogenesis imperfecta (OI), related to the different types of the disease.

DESIGN

A prospective, descriptive study.

MATERIALS AND METHODS

Fifty-four children with OI and their parents participated at the start of the study. At the end, 44 children participated in the assessment of functional skills and 42 of them participated in clinical assessment (OI type I, n = 19; OI type III, n = 13; OI type IV, n = 10). Range of joint motion was measured by means of goniometry. Generalized hypermobility was scored according to Bulbena. Manual muscle strength was scored by means of the MRC grading system. The level of ambulation was scored according to Bleck, and functional skills and caregiver assistance were scored with the Pediatric Evaluation of Disability Inventory.

RESULTS

The different types of OI have impact on impairment, functional limitation, and disability. Almost all impairment parameters did not change significantly over time, whereas some disability parameters seemed to improve significantly.

CONCLUSIONS

Impairment parameters in OI are presumably not always preconditions for functional limitation and disability. A 1-year follow-up revealed no significant changes in impairment parameters, whereas some disability parameters improved. Treatment strategies in OI should, therefore, focus primarily on improving functional ability, with respect to the natural course of the disease, and not only on impairment parameters.

Complications of the Bailey-Dubow elongating nail in osteogenesis imperfecta: 34 children with 110 nails

The Bailey-Dubow nail, inserted in the femur or tibia of 34 children with osteogenesis imperfecta (OI), was studied retrospectively. Comparing the various groups of OI, no significant difference was found. Location of the nail (tibia or femur) did not influence the complication rate significantly. The reoperation rate was 29%, a rate comparable to that reported in earlier studies. The part of the nail located around the knee had a significantly higher migration rate (P = 0.005 at obturator ends and P = 0.007 at sleeve ends). Migration of the nail was the reason to reoperate in 50% of the patients. Better anchoring of the T-piece will substantially decrease the complication rate. In consideration of the different functional capacities of the OI population, the complications are likely related more to the hardware than to the patient.

Temporary muscle weakness in the early phase of distraction during femoral lengthening. Clinical and electromyographical observations

Limb lengthening by distraction osteogenesis has a high complication rate. Much of the response of muscle and nerve to distraction is still unknown. Thirteen children, mean age 12.6 yr (8.4-17.3) were surgically treated by the Ilizarov procedure for acquired and congenital femoral limb-length discrepancy. All children showed a decrease in muscle strength in the quadriceps, shortly after the operation, followed by an improvement before distraction started. After an elongation in the early phase of distraction (1 to 2 cm), muscle weakness was again observed and the muscle strength gradually increased after ending of distraction. To provide an explanation for this clinical observation, in one patient (limb lengthening of 4.1 cm) muscle strength measurements were extended with investigations of Hoffman (H) reflex of m. vastus medialis and determination of muscle-fiber conduction velocity of m. vastus lateralis by using the invasive method (IMFCV). The examinations were performed every two weeks during 20 weeks and 12 weeks after removing the cast. A severe decrease in muscle strength of the corrected limb was found after 1.2 cm of distraction with a recovery in muscle strength before lengthening was ended. EMG study showed the same tendency. Denervation was observed as evidence by positive sharp waves and reduced IMFCV findings. Evidence for reinnervation before lengthening was ended, was found by an increased range of velocities consisting of a combination of slow potentials and gradual increase of the velocity of reinnervated fibers (increased Fast/Slow ratio). The latencies of M waves and H-M interval from both legs separated as well after 2.25 cm of distraction. At the end of the follow-up period, the H-M interval reached the preoperative value. It is suggested that these neurogenic changes are an effect of axonal dysfunction and the local effect due to intraoperative trauma and stretching might affect nerve blood flow adversely.

Influence of infant-walkers on motor development: mimicking spastic diplegia?

We discuss two patients, who used an infant walker during the period in which they learned to walk. The influence on qualitative and quantitative motor development is illustrated in this report. A disharmonic and delayed motor development, contractures of the calf-muscles and motor development mimicking spastic diplegia are considered to be caused by the early use of infant walkers. As illustrated by the literature, infant walkers do not have any positive effect on improving motor development. Vulnerability of infants with regards to accidents is increased. In our opinion, the use of infant-walkers should be discouraged.

Osteogenesis imperfecta in childhood: treatment strategies

Osteogenesis imperfecta (OI) is a skeletal disorder of remarkable clinical variability characterized by bone fragility, osteopenia, variable degrees of short stature, and progressive skeletal deformities. Additional clinical manifestations such as blue sclerae, dentinogenesis imperfecta, joint laxity, and maturity onset deafness are described in the literature. OI occurs in about 1 in 20,000 births and is caused by quantitative and qualitative defects in the synthesis of collagen I. Depending on the severity of the disease, a large impact on motor development, range of joint motion, muscle strength, and functional ability may occur. Treatment strategies should primarily focus on the improvement of functional ability and the adoption of compensatory strategies, rather than merely improving range of joint motion and muscle strength. Surgical treatment of the extremities may be indicated to stabilize the long bones to optimize functional ability and walking capacity. Surgical treatment of the spine may be indicated in patients with progressive spinal deformity and in those with symptomatic basilar impression.

Spinal complications in osteogenesis imperfecta: 47 patients 1-16 years of age

We examined in a cross-sectional study, 47 children (mean age 7.7 (1-16) years) with osteogenesis imperfecta (OI) to find the prevalence of spinal deformities and to correlate these observations with anthropometry. The associations between dentinogenesis imperfecta, joint hypermobility and spinal deformities were also studied. Disproportion in stature in OI type I and type IV was mainly caused by spinal involvement, as evidenced by a greater decrease in body height than in leg length. In OI type I, the decrease in sitting height was mainly caused by platyspondyly, whereas in OI types III and IV, it was also caused by progressive scoliosis and kyphosis. Scoliosis was present in 22 children, and pathological kyphosis in 18, mainly in the severe OI types. Basilar impression was observed in 10 children, mainly in type III. Children with dentinogenesis imperfecta seemed to be prone to develop scoliosis, pathological kyphosis and basilar impression. Children with generalized joint hypermobility were less prone to develop scoliosis and basilar impression. Our observations may contribute to a better understanding of the risk factors for progressive spinal deformities in OI.

Instrumentation for correction and fixation of scoliosis in fibrous dysplasia of the thoracolumbar spine

A case report is presented in which correction of a thoracolumbar scoliosis, due to extensive fibrous dysplasia, is achieved using segmental spinal instrumentation with a 6-year follow-up. Pseudoarthrosis developed due to insufficient hook fixation at the sacrum.

Bruck syndrome: a rare combination of bone fragility and multiple congenital joint contractures

Bruck syndrome manifests with combined features of arthrogryposis and osteogenesis imperfecta. It is a distinct autosomal recessive disorder with normal collagen I. The main features are osteoporosis, bowing of the long bones, scoliosis due to vertebral deformities, and congenital joint contractures. The presence of arthrogryposis differentiates this syndrome from "classical" osteogenesis imperfecta. A family with three affected children is presented with a review of the literature.

Osteogenesis imperfecta in childhood: impairment and disability

OBJECTIVE

To determine clinical characteristics in children with osteogenesis imperfecta (OI) regarding impairment (range of joint motion and muscle strength) and disability (functional skills) in relation to the different types of the disease, and to study the correlation between characteristics of impairment and disability.

METHODS

In a cross-sectional study 54 children with OI (OI type I: 24; OI type III: 15; OI type IV: 15), the range of joint motion, muscle strength, and functional ability were measured in a standardized way and analyzed statistically.

RESULTS

The range of joint motion in almost all joints differed significantly with respect to the different disease types. In OI type I patients, generalized hypermobility of the joints was present, without decrease in joint motion. In OI type III the extremities were severely maligned, especially the lower limbs. In type IV the upper and lower extremities were equally maligned. Muscle strength differed significantly with respect to the different types of OI. In type I patients, muscle strength was normal except for the periarticular hip muscles. In type III, especially in the lower extremities, muscle strength was severely decreased, with a muscular imbalance around the hip joint. In type IV, muscle strength was mainly decreased in the proximal muscles of the upper and lower extremities. In children </=7.5 years of age, significant differences existed among the different disease types in functional skills regarding mobility. No significant difference was observed in self-care and social function, although the most severely affected children showed a tendency to score better with social function. Older children differed significantly concerning mobility and self-care items. In children </=7.5 years old, a correlation was sometimes observed between impairment and disability items, although in older children a moderate to good correlation was always present (r > .6).

CONCLUSION

In OI, severity-related profiles exist, within the different subtypes of the disease, regarding range of joint motion, muscle strength, and functional skills. In younger children, impairment parameters do not sufficiently correlate for disability. Rehabilitation strategies in younger children should therefore focus on improvement of functional skills and not only on impairment parameters.

Intramedullary rodding in type III osteogenesis imperfecta. Effects on neuromotor development in 10 children

We studied retrospectively gross motor development and the impact of intramedullary rodding in 10 children with type III osteogenesis imperfecta (OI). There was a pronounced delay in motor development and the order in achieving gross motor milestones differed from the normal developmental sequence. Static milestones developed at an earlier stage than dynamic milestones. Intramedullary rodding of the lower extremities prior to the age of 3.5 years enhanced neuromotor development, especially regarding the milestones supported standing, rolling from prone to supine and crawling with abdomen on the floor. The different sequence in achieving gross motor milestones should have implications for future rehabilitation programs and for orthopedic surgery.

[2 children with discitis]

The childhood form of discitis was diagnosed in a 2-year-old girl and a 5-year-old boy. They presented with an antalgic posture, muscular defense and a positive Gowers sign. Characteristic symptoms of this childhood discitis form the triad: unexplained fever, increased erythrocyte sedimentation rate and symptomatic narrowing of an intervertebral space.
