Article
Objective: The objective was to investigate whether muscle strength in the nonaffected and affected upper extremities (UEs) in children (7-12 years) with unilateral spastic cerebral palsy (USCP) differs from that in children with typical development (TD). Methods: A cross-sectional study design was used. Isometric arm strength (wrist flexion, wr...
Article
Background: For children with unilateral spastic cerebral palsy (USCP), reduced muscle strength can lead to activity limitations. However, none of the existing measures of upper extremity strength measure strength in the context of functional activities in which strength must be maintained for several seconds. Objective: The objective of this st...

Many trials fail to include the targeted number of participants, causing scientific and ethical problems. The COAD trial of home-based training programs (HBTPs) for children with unilateral cerebral palsy (CP) encountered recruitment problems, even though the parent-delivered home-based approach complies with recent health-care developments in the...
Article
Purpose: To investigate test–retest and inter-rater reliability of maximum isometric arm muscle strength measurements using the hand-held dynamometer (HDD) and maximum isometric grip and pinch strength measurements using the Biometrics E-Link Evaluation System in children aged 7–12 years with unilateral spastic cerebral palsy. Materials and methods...

Background: As part of the COAD-study two home-based bimanual training programs for young children with unilateral Cerebral Palsy (uCP) have been developed, both consisting of a preparation phase and a home-based training phase. Parents are coached to use either an explicit or implicit motor learning approach while teaching bimanual activities to...
Article
Full-text available
Background: Home-based training is considered an important intervention in rehabilitation of children with unilateral cerebral palsy. Despite consensus on the value of home-based upper limb training, no evidence-based best practice exists. Promoting compliance of children to adhere to an intensive program while keeping parental stress levels low i...

To evaluate arm-hand therapies for neurological patients it is important to be able to assess actual arm-hand performance objectively. Because instruments that measure the actual quality and quantity of specific activities in daily life are lacking, a new measure needs to be developed. The aims of this study are to a) elucidate the techniques used...
Article
Full-text available
Neurological patients often encounter arm-hand problems in daily life. Body worn sensors may be used to assess actual performance by quantifying specific movement patterns associated with specific activities. However, signal reliability during activities of daily living should be determined first. Aim is to determine to what extent standardized arm...

This study aims to assess the extent to which accelerometers can be used to determine the effect of robot-supported task-oriented arm-hand training, relative to task-oriented arm-hand training alone, on the actual amount of arm-hand use of chronic stroke patients in their home situation. This single-blind randomized controlled trial included 16 chr...
Article
INTRODUCTION: Patients with neurological diseases such as stroke or cerebral palsy often encounter arm-hand problems during daily life. Assessment is important to determine the progress of arm-hand performance in patients during rehabilitation, and to ascertain the effectiveness of therapies. Many instruments are available to assess capacity or per...
Article
Full-text available
Assessment of arm-hand use is very important in children with cerebral palsy (CP) who encounter arm-hand problems. To determine validity and reliability of new instruments to assess actual performance, a set of standardized test situations including activities of daily living (ADL) is required. This study gives information with which such a set for...

The Observational Skills Assessment Score (OSAS) measures amount and quality of use of the affected hand in children with unilateral Cerebral Palsy (CP) in bimanual activities and could therefore be a valuable addition to existing assessment tools. The OSAS consists of tasks that are age appropriate and require use of the affected hand. To measure...

Loss of arm-hand performance due to a hemiparesis as a result of stroke or cerebral palsy (CP), leads to large problems in daily life of these patients. Assessment of arm-hand performance is important in both clinical practice and research. To gain more insight in e.g. effectiveness of common therapies for different patient populations with similar...

Prospective case-control study. Patients from regional hospitals, tested in a rehabilitation research center. Twenty-nine patients with a recent (6wk...
Article
Spinal cord injured (SCI) people try to compensate for the loss of postural muscle function by increased use of non-postural muscles. Such alternative muscle use, however, may necessitate important modifications in motor control. In this study motor programming processes were investigated in three groups, i.e. in high thoracic SCI, low thoracic SCI...

Article
To compensate for postural muscle function loss spinal cord injured (SCI) people have to use parts of the sensorimotor system which are still intact. In this study, postural control was investigated in high and low thoracic SCI people and in able-bodied controls, using a bimanual forward-reaching task. Muscle activity was recorded bilaterally from...
Article
The development of new patterns of postural control in patients with a complete thoracic spinal cord injury (SCI) during their active clinical rehabilitation was studied. Especially the role of non-postural muscles, like the latissimus dorsi (LD) and the trapezius pars ascendens (TPA), in maintaining and restoring sitting balance during standardize...
Article
One of the basic aims in the rehabilitation of thoracic spinal cord injured (SCI) patients concerns the regaining of sitting posture control. This implies the development of new postural strategies requiring the adjustment of motor programming processes. The aim of this study was to investigate the time course of postural reorganization during acti...
Article
Postural muscle use during sitting balance control was studied in persons with a complete thoracic spinal cord injury (SCI). It was hypothesized that these subjects use non-postural muscles such as the latissimus dorsi (LD) and trapezius pars ascendens (TPA) to restore sitting balance, whereas non-SCI subjects primarily use their erector spinae (ES...
