Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
- Brief name of intervention: A sit-to-stand exercise program
- Procedures: Children will receive 1 hour of physical therapy which consists of 30 minutes of sit-to-stand training and 30 minutes of regular physiotherapy. Sit-to-stand training has three phases: 1) repetition of part of the sit-to-stand task, 2) repetition of all the sit-to-stand movement, and 3) repetition of all the sit-to-stand movement applied within the context of self-care tasks. The regular physiotherapy program consists of 15 minutes of balance training in sitting and standing and 15 minutes of walking training with assistive devices that the individual child usually uses.
(The details of balance training and walking training will be individualised depending on the child’s ability.)
- Who provided: Two registered physiotherapists experienced in working with children with cerebral palsy. Child’s caregiver for the home program.
- Mode of delivery: Individually face-to-face 1 physiotherapist per 1 child and individually face-to-face 1 caregiver per 1 child.
- When and how much: Training duration is 6 weeks, the frequency of the training is 5/week, and session length 60 minutes; 30 minutes in a sit-to-stand training program and 30 minutes in regular physiotherapy.
- Intensity and volume: 3 sets of 25 repetitions of sit-to-stand and rest between each set 2-3 minutes for the second phase of the sit-to-stand training program. Thus, repetitions in this phase will be 75 repetitions/day.
- Where: 2 days a week in the private training room, located in the Physical Therapy Unit of Songklanagarind hospital, Thailand. And 3 days a week at child’s home as the home program which is the same exercise, time, frequency and duration as in the Physical Therapy Unit of Songklanagarind hospital.
- How well: Physiotherapists and parents will complete an exercise diary recording the number of repetitions of sit-to-stand in each session.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The independent researcher who prepares the allocation sequence will prepare sealed opaque sequentially numbered envelopes. Only after written informed consent has been obtained and baseline testing has been completed will the next sealed envelope be opened and group allocated by an independent physiotherapist at the study site.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Children with cerebral palsy will be stratified by their level of functional ability as classified by the Gross Motor Function Classification System (GMFCS), permuted blocks will be generated by an independent researcher not involved in recruitment, training or assessment, to randomly allocate participants to two groups (a usual care control group and a sit-to-stand experimental group).

Efficacy
Statistical methods / analysis
Descriptive statistics will use to describe the demographic characteristic of participants. To evaluate the effect of sit-to-stand training on self-care and mobility task in children with cerebral palsy, ANCOVA will be used to compare the main outcomes of primary and secondary continuous outcomes between the control group and experimental group after 6 weeks using the baseline value as the covariate. Standardized mean differences will be calculated from change scores from week 0 to week 6, divided by the standard deviation of the difference scores. Standardized mean differences, also known as effect sizes, will be considered as small at 0.2, moderate at 0.5 and large at 0.8. Consistent with the principle of intention to treat, all available data will be analyzed according to group allocation, without consideration of the level of adherence. Between-group differences will be reported as mean differences with 95% confidence intervals. Statistical significance will be set at a=0.05.
For the qualitative data, thematic analysis will be used to identify key concepts from the qualitative data, which will be then clustered to create themes. Each interview will be audio-recorded and transcribed verbatim to Thai language first. To increase the trustworthiness, after the interview the researcher will provide participants with a copy of their transcript to check that it is an accurate representation of their thoughts and to see if they want to add any other comments. Then, the transcript will be translated into English (by an English expert from the International Affairs Office, Faculty of Medicine, Prince of Songkla University). The translated English transcripts will be checked to determine if they accurately represent the thoughts of the participants by the bilingual researcher. All interview transcripts in English will be coded line-by-line by two investigators independently. After the initial coding, the researchers will compare codes and discuss any differences until a consensus is reached. Thematic analysis will be used to identify key concepts and ideas, which will be clustered to create a thematic structure.
To assess attendance for the experimental group, exercise diary records of each child will be kept for each session, and the reason for non-attendance will be recorded. An overall attendance percentage (ratio of the number of training sessions attend to the total number of sessions prescribed, multiplied by 100) will be determined. Adherence will be described by the number of repetitions of sit-to-stand completed in each session as a proportion of the number prescribed by the physiotherapist. Adverse events will be categorized as serious or non-serious, expected or unexpected. Non-serious events do not need medical attention, and would not cause children to miss subsequent exercise session. Expected adverse events would be those events more likely to occur in the environment of exercise training such as falling. Adverse events unrelated to the study would be those events that are external to the exercise sessions, but stop a child from attending one or more sessions such as other an injury from other activities.
For the sample size estimation of this pilot study, to gain a preliminary estimate of the effects of sit-to-stand training on mobility and self-care function using the Functional Independence Measure for Children (WeeFIM), a sample size of n=42 (21 in each group) will be sufficient to detect a large, clinically worthwhile effect (0.8) in the mobility (4.3 units/35) and self-care (5.2 units/42) domains of WeeFIM(Oeffinger et al., 2008) at a level of 0.05 and power of 0.7. For an intervention of this type, it is not expected that such a large effect will be obtained; however, the sample will enable estimates of effect to be obtained for continuous primary and secondary outcomes that will inform future studies, and provide a sufficient sample that will likely achieve saturation for the qualitative analysis.

Summary
Brief summary
The abnormal movements and posture in children with cerebral palsy who have moderate to severe disability can lead to impaired sit-to-stand function which can in turn impact on children’s ability to independently perform mobility and self-care tasks. Therefore, the primary aim of this pilot trial is to investigate the effects of sit-to-stand task-specific training on mobility and self-care function in children with cerebral palsy with moderate to severe motor dysfunction. The secondary aims are: to evaluate the effects of sit-to-stand training on: sit-to-stand performance and caregiver burden; while exploring the experiences and perceived positive and negative effects of the training on primary caregivers; their adherence to the intervention; and identification of any adverse events associated with training. This study will be conducted in Thailand, with 42 children with cerebral palsy aged 4 to 12 years randomly allocated to routine physiotherapy or sit-to-stand exercise training in addition to routine physiotherapy. Outcomes will be measured at baseline and 7 weeks after randomisation. It is hypothesised that sit-to-stand task-specific training is a feasible and useful intervention for improving mobility and self-care functions in children with cerebral palsy who have moderate to severe disability.
