Study protocol for the 'preventing functional decline in acutely hospitalised older patients (PREV_FUNC)' study: effects of two multicomponent exercise programmes on physical function - a three-armed randomised controlled trial.

INTRODUCTION: Acutely hospitalised older patients often live with frailty and have an increased risk of impaired physical function. Previous studies suggest that exercise might mitigate the risk of physical impairment; however, further research is needed to compare the effect of different types of exercise interventions. In this paper, we report a protocol for a trial that aims to examine (1) if multicomponent exercise interventions (interventions that include both mobility and strengthening exercises) have effects on physical function compared with usual care in older adults and (2) if a comprehensive multicomponent exercise programme is more effective than a simple multicomponent exercise programme that only include walking and sit-to-stand exercises. METHODS AND ANALYSIS: This is a three-armed randomised controlled trial, with two intervention groups (comprehensive and simple exercise programme) and a control group receiving usual care. We will include 320 participants aged ≥75 years from geriatric medical departments of four hospitals in Stockholm, Sweden. Assessments will be conducted at hospital admission, discharge and 3 months thereafter concerning physical function (primary outcome), activities of daily living, health-related quality of life, sarcopenia and falls. The number of readmissions will be registered up to 1 year after discharge. Data will be analysed with linear mixed effects models, according to the intention-to-treat approach. ETHICS AND DISSEMINATION: Ethical approval for this trial has been granted by the Swedish Ethical Review Authority (approval number 2022-03032-01). Data collection will consider the information requirement, the requirement of consent, confidentiality obligations and the utilisation requirement. Trial findings will be disseminated through multiple channels, including scientific publications and conferences, and workshops with healthcare professionals and the public. TRIAL REGISTRATION NUMBER: NCT05366075.

Longitudinal development of hand use in children with unilateral spastic cerebral palsy from 18 months to 18 years.

AIM: To describe the development of the use of the affected hand in bimanual tasks in children with unilateral cerebral palsy (CP) from 18 months to 18 years. Specifically, whether early development can be confirmed in a larger cohort and how development progresses during adolescence. METHOD: In total, 171 participants (95 males, 76 females; mean age 3 years 1 month [SD 3 years 8 months], range 18 months-16 years at inclusion) were classified in Manual Ability Classification System (MACS) levels I (n = 41), II (n = 91), and III (n = 39). Children were assessed repeatedly (median 7, range 2-16 times) with the Assisting Hand Assessment: in total 1197 assessments. Developmental trajectories were estimated using a nonlinear mixed effects model. To further analyse the adolescent period, a linear mixed model was applied. RESULTS: The developmental trajectories were different between participants in MACS levels (MACS I-II, II-III) in both rate (0.019, 95% confidence interval [CI] 0.006-0.031, p = 0.034; 0.025, 95% CI 0.015-0.037, p < 0.001) and limit (19.9, 95% CI 16.6-23.3, p = 0.001; 7.2, 95% CI 3.3-11.2, p < 0.003). The individual variations were large within each level. The developmental trajectories were stable over time for all MACS levels between 7 and 18 years (p > 0.05). INTERPRETATION: Children and adolescents with unilateral CP have considerable development at an early age and a stable ability to use their affected hand in bimanual activities from 7 to 18 years in all MACS levels.

The effectiveness of Baby-CIMT in infants younger than 12 months with clinical signs of unilateral-cerebral palsy; an explorative study with randomized design.

AIM: To explore the effectiveness of baby-CIMT (constraint-induced movement therapy) and baby-massage for improving the manual ability of infants younger than 12 months with unilateral cerebral palsy (CP). METHOD: Infants eligible for inclusion were 3-8 months old with asymmetric hand function and at high risk of developing unilateral CP. Thirty-seven infants were assigned randomly to receive baby-CIMT or baby-massage. At one year of age 31 children were diagnosed with unilateral CP, 18 (8 boys, 6.1±1.7months) of these had received baby-CIMT and 13 (8 boys, 5.0±1.6months) baby-massage. There were two 6-week training periods separated by a 6-week pause. The Hand Assessment for Infants (HAI), Assisting Hand Assessment (AHA), the Parenting Sense of Competence Scale (PSCS) and a questionnaire concerning feasibility were applied. RESULTS: There was improvement in the "Affected hand score" of HAI from median 10 (6;13 IQR) to 13 (7;17 IQR) raw score in the baby-CIMT group and from 5 (4;11 IQR) to 6 (3;12 IQR) for baby-massage with a significant between group difference (p=0.041). At 18-month of age, the median AHA score were 51 (38;72 IQR) after baby-CIMT (n=18) compared to 24 (19;43 IQR) baby-massage (n=9). The PSCS revealed an enhanced sense of competence of being a parent among fathers in the baby-CIMT group compared to fathers in the baby-massage (p=0.002). Parents considered both interventions to be feasible. CONCLUSION: Baby-CIMT appears to improve the unimanual ability of young children with unilateral CP more than massage.

Longitudinal development of hand function in children with unilateral spastic cerebral palsy aged 18 months to 12 years.

AIM: The aim of the study was to describe the development of hand function, particularly the use of the affected hand in bimanual tasks, among children with unilateral cerebral palsy aged 18 months to 12 years. METHOD: A convenience sample of 96 children (53 males, 43 females) was assessed with the Assisting Hand Assessment (AHA) at regular intervals from the ages of 18 months to 12 years. The children ranged from 17 to 127 months (median age 24mo) at recruitment. Subgroups were created to identify differences in development using the child's AHA at 18 months and the Manual Ability Classification System (MACS). A nonlinear mixed effects model was used to analyze data according to a 'stable limit' development model. RESULTS: The results were based on 702 AHA sessions. The children showed a rapid development at a young age and reached 90% of their stable limit between 30 months and 8 years. The subgroups, based on the 18-month AHA and the MACS levels respectively, had distinctly different patterns of development. INTERPRETATION: The AHA at 18 months may be used to make a crude prediction of future development.

Improvements in bimanual hand function after baby-CIMT in two-year old children with unilateral cerebral palsy: A retrospective study.

The common assumption that early-onset intensive intervention positively affects motor development has rarely been investigated for hand function in children with unilateral cerebral palsy (CP). This retrospective study explored the possible impact of baby constraint-induced movement therapy (baby-CIMT) on hand function at two years of age. We hypothesized that baby-CIMT in the first year of life would lead to better bimanual hand use at two years of age than would not receiving baby-CIMT. The Assisting Hand Assessment (AHA) was administered at age 21 months (SD 2.4 months) in 72 children with unilateral CP, 31 of who received baby-CIMT. When dividing the children into four functional levels based on AHA, the proportional distribution differed between the groups in favour of baby-CIMT. Logistic regression analysis indicated that children in the baby-CIMT group were more likely than were children in the no baby-CIMT group to have a high functional level, even when controlling for the effect of brain lesion type (OR 5.83, 95% CI 1.44-23.56, p = 0.001). However, no difference was found between groups in the odds of having a very low functional level (OR 0.31, 95% CI 0.08-1.17, p = 0.084). The result shows that baby-CIMT at early age can have a positive effect. Children who received baby-CIMT were six times more likely to have a high functional level at two years of age than were children in the no baby-CIMT group.

Is outcome of constraint-induced movement therapy in unilateral cerebral palsy dependent on corticomotor projection pattern and brain lesion characteristics?

AIM: The aim of the study was to explore individual variations in outcome of hand function after constraint-induced movement therapy (CIMT) in relation to the organization of corticomotor projection and brain lesion characteristics in participants with unilateral cerebral palsy (CP). METHOD: Sixteen participants (eight males, eight females; mean age 13 y, [SD 2 y] range 10-16 y) with unilateral CP (nine right-sided; Manual Ability Classification System [MACS] level I, n=1; level II, n=15) who participated in a 2-week CIMT day camp (63 h) were included in the study. Various aspects of hand function were measured by the Jebsen-Taylor Hand Function Test (JTHFT), the Assisting Hand Assessment (AHA), and the Melbourne Assessment, both before and after the day camp. Transcranial magnetic stimulation was used to explore the corticomotor organization, and brain lesion characteristics were described by visual assessment of conventional structural magnetic resonance images. RESULTS: At a group level, the training was associated with significant improvements in JTHFT (p=0.003) and AHA (p=0.046), but not in Melbourne Assessment scores. Improvements were found in all types of corticomotor projection patterns, i.e. contralateral, mixed, and ipsilateral. There was no relationship between functional improvement and brain lesion characteristics. INTERPRETATION: Individuals with CP experience improved motor outcomes after CIMT, independent of corticomotor projection pattern and lesion characteristics.
