Bulletin of Faculty of Physical Therapy volume 29, Article number: 40 (2024)
Abstract
Background
Children with spastic diplegic cerebral palsy (CP) often demonstrate gluteus medius weakness that causes balance deficits and frequent falling during walking.
Purpose
The aim of the study was to evaluate the combined effects of functional task training with electrical stimulation of bilateral hip abductor muscles on motor abilities (standing and walking) and balance in children with spastic diplegic CP.
Methods
Thirty children with diplegic CP of both sexes whose ages ranged from 7 to 10 years were assigned randomly into two equal groups. For both groups, motor abilities were assessed by gross motor function measure (GMFM), and balance (static and dynamic) was assessed by the humac balance system before and after the study. The control group received a functional training program focusing on standing walking and balance exercises. While children in the study group received the same functional training program with bilateral electrical stimulation of gluteus medius muscles for 50 min. The treatment program for both groups was conducted for 3 sessions/week for 8 weeks.
Results
There were statistically significant differences between the control and study group post-treatment in GMFM as well as the center of pressure test and weight shift test in favor of the study group (p < 0.05).
Conclusion
Using functional task training with electrical stimulation for treatment of children with spastic diplegic CP have significant effects on improving their motor abilities and balance that suggests using it in rehabilitation for these children.
Introduction
Cerebral palsy (CP) is a common neurodevelopmental disorder caused by non-progressive lesions of the immature brain. The clinical signs and characteristics of spastic CP include motor deficits and postural abnormalities, increased muscle tone, and limited range of motion. Children with CP usually have balance problems due to neuromuscular, musculoskeletal, and sensory system deficits resulting in walking impairment [1]. The problems of gait are instability in ambulation and a higher incidence of falls. It is due to spasticity, difficulty of initiation of activity, reduced voluntary movement performance, enhanced walking cost efficiency, and early fatigue [2]. Diplegia is the most prevalent form of spastic CP, which manifests as symmetrical involvement of both lower limbs. It makes up 35% of the CP population [3]. Children who suffer from spastic diplegia may display clumsiness and fall frequently during regular motor activities. They may also have difficulty standing up on their own and walking abnormalities as a result of balance, motor control deficiencies, and spasticity [4]. Complex integration of multiple body systems such as the vestibular, visual, proprioceptive, and higher-level premotor systems, is required to achieve balance [5]. Impaired motor control is one of the most common neuromuscular deficits in children with spastic CP and often occurs in combination with muscle weakness and spasticity [4].
Numerous musculoskeletal deformities, such as pelvic malalignment, non-synchronization between the trunk and lower limbs, lack of proprioception, and muscle imbalance can cause numerous functional difficulties in children with spastic diplegia. Otherwise, spasticity causes difficulty in initiation movement, decreased performance of voluntary movement increased cost efficiency of gait. A healthy gait pattern requires good coordination between the pelvis and lower extremities [6].
There are numerous strategies of treatment for CP: pharmacological and surgical options, as well as physiotherapy approaches. Physiotherapy approaches that are currently available for the treatment of CP are neurodevelopmental therapy, proprioceptive neuromuscular facilitation, constraint-induced movement therapy, functional task training program, and functional electrical stimulation [7].
The purposes of the functional-task training program were to create and enhance a wider range of movement patterns, with a focus on strengthening muscles. Also, this exercise program was used to enhance postural adaptation, increase postural control, and give opportunities for age-appropriate abilities and performance [5].
The functional task training program is a potential neurological rehabilitation technique for the enhancement of functional performance in children with CP. This program included both walking and non-walking exercises like getting up from a seated position, getting on and off a bench, climbing up and down stairs; and walking on ramps as well as flat surfaces [8].
Functional electrical stimulation (FES) is used for stimulation during voluntary and functional movements. This is accomplished by providing electrical stimulation to muscles that, during contraction, lead to suitable and functional movement [9]. It is frequently used to increase the range of motion, decrease muscle stiffness, strengthen muscles, improve upper extremity function, and increase walking speed [10]. NMES is applied via surface electrodes. It is a non-invasive approach that is generally well tolerated [11]. In addition, it has been demonstrated that when muscle training is implemented within functional activities, the gains of performance are faster compared with training isolated from the functional activities [12].
Previous research has shown the effectiveness of the combination of a functional task training program and functional electrical stimulation on the gastrocnemius muscle to improve motor capacity [12]. Therefore, the purpose of the current study was to evaluate the combination of functional task training with electrical stimulation of bilateral hip abductor muscles and its effects on motor functions (standing, walking) and balance in children with spastic diplegia.
Study design
This prospective randomized clinical trial was carried out in the outpatient clinic of Itay Elbaroud General Hospital and Health Insurance Hospital; it was conducted from January 2023 to September 2023.
Ethical consideration
This trial was approved by the Research Ethical Committee of the Faculty of Physical Therapy, Cairo University (P.T.REC/012/004508). The current study was registered on the Clinical Trials Protocol Registration and Results System (NCT06234215).
Sample size calculation
G*POWER statistical software (version 3.1.9.2; Universitat Kiel, Germany) was used to carry out sample size calculation relying on the finding of El-Shamy and El Kafy 2021; and suggested that the required size of each group is 15 subjects. The calculations were made using α = 0.05, power = 80% and effect size = 1.1, and allocation ratio N2/N1 = 1.
Subjects
Thirty children with spastic diplegic CP of both sexes were recruited in this trial. Children aged 7 to 10 years with Modified Ashworth Scale scores of 1 to 1 + of spasticity were included [13]. Based on the Gross Motor Function Classification system, their motor functions were at levels I and II [14]. Participants demonstrated cooperation and were able to follow study instructions. Children with epilepsy, musculoskeletal deformities in the upper, and lower extremities or spine, vision or hearing issues, injection of botulinum toxin, or orthopedic surgery during the previous 6 months or during the research period were excluded.
Children were assigned by simple randomization via closed sealed envelopes into two groups (control and study). The control group included 15 children and they received the functional training program. The study group included 15 children. They received the same functional training program and electrical stimulation during exercise for about 50 min. The treatment program was conducted for both groups for successive 8 weeks.
Recruitment and randomization
Forty-one children had their eligibility evaluated for participation in this trial. Four children were taken out because their parents refused to participate in the study, while seven other children were excluded because they did not match the criteria for inclusion. Using closed sealed envelopes, the randomization procedure was carried out after the baseline outcomes measurements. The researcher produced 30 closed sealed envelopes, one inside each that included a card labeled “study group” or “control group”. Then, each child was instructed to draw one sealed envelope that contained whether he/she was allocated to the control group or the study group.

For both groups physical therapy tools (mat, wedge, balance board, inclinator, parallel bar, stepper, shifter, and stairs) were used. For the study group (EV-906) Digital TENS/EMS neuromuscular stimulator device was used.
Procedures
-
I)
For evaluation
All parents became aware of all goals and study technique without any risk before participation of their children. Before the testing session, each child was given instructions regarding the evaluative procedures after agreeing to a written consent form. This was done to ensure that all of the children were aware of the device and the steps involved in the evaluation process. Before and after 8 weeks of the procedure, assessments were given to each child in both groups in a quiet, warm environment.
Test sessions:
-
Demographic data including child’s name, age, and gender were collected and reported in the evaluation sheet.
-
Assessment of GMFM: items of both standing and walking domains were assessed for each child and the sum of all scores was recorded.
-
Assessment of balance: the HUMAC Balance System is a balance board combined with the HUMAC balance Software to offer a powerful assessment tool for static and dynamic balance. The device was fed specific settings. Child’s weight, height, birthdate, and feet position on the board. The HUMAC Balance System assesses static balance via a center of pressure test (COP) and dynamic balance via a weight shift test. During the COP test each child was asked to keep the movable point in the center of the circle on the visual feedback screen while he/she was standing. While the weight shift test was used to assess dynamic balance, each child was asked to put the movable point on the bright spot on the visual feedback screen by shifting body weight (mediolateral and anteroposterior) without moving feet.
The testing time lasted for 60 s for every child, and the average of the three repeats was recorded. After completion of the test, a printout was obtained.

Study group
Children in this group received the same training program combined with neuromuscular electrical stimulation by using (EV-906 digital TENS/EMS) on the gluteus medius muscle bilaterally for 50 min [12].
The treatment plan was clarified to the child and his/her parents. Two active electrodes spaced 2 cm apart and parallel to the muscle fibers were stuck bilaterally on the gluteus medius muscle [16].
Parameters
After optimizing the positioning of the electrodes, the electric current characteristics are 300 μs pulse width that was symmetrical in nature. Pulse intensity ranged from 17 to 33 mA and the stimulation frequency ranged from 26 to 30 pps, to achieve a noticeable muscle contraction [12].
Statistical analysis
Unpaired t test was utilized to make a comparison between groups regarding the group’s age, weight, and height between groups. The Mann–Whitney test was utilized to make a comparison between groups’ GMFCS levels. The chi-square test was utilized to make a comparison between groups regarding sex and the distribution of spasticity. The Shapiro–Wilk test was conducted to test the normal distribution of data. To evaluate the homogeneity between groups, Levene's test for homogeneity of variances was used. A paired t test was used to compare each group's pre- and post-treatment periods, while an unpaired t test was used to compare the GMFM scale, COP, and weight shift between the groups. The level of significance was set at p < 0.05. The statistical software for social sciences (SPSS) version 25 for Windows (IBM SPSS, Chicago, IL, USA) was used for all statistical analysis.

Discussion
The present study included the spastic diplegic type of CP which is the most common type of spastic CP [3]. Children with spastic diplegic CP face a variety of troubles including poor balance, walking disturbances, and frequent falls. Balance problems that are common in children with spastic diplegia may be partially explained by these children’s impairments in the postural control system [1]. Children with CP are often unable to stand up straight, and some may need assistance. Muscle strength is clearly necessary for achieving gross motor activities, but it is unknown if the development of standing capacity depends on it or if there are other factors affecting the ability to develop standing in CP [17]. Therefore, the purpose of this study was to determine how functional task training and electrical stimulation of bilateral hip abductor muscles affect standing, walking, and balance in children with diplegia.
Children between the ages of 7 to 10 years were recruited in this study. It comes in agreement with Shumway-Cook and Woollacott [18] who stated that postural control is practically developed as an adult in 6–10 years of age. The study’s age selection was matched with Hallemans et al. [19] who emphasized that at this age, standing and walking have completely matured and resemble an adult’s pattern, so the developmental issue as a factor affecting the gait in these children can be excluded. It was reported that lack of hip flexion, extension, and adductor spasticity in the legs can cause delays in independent standing and walking in people with spastic diplegia lasting up to 6 years of age [20]. A previous study by Usama et al. [21] stated that children aged between 5 and 12 years old, had a good performance like adults during balance assessment using humac system. So, children aged from 7 to 10 years were selected as they understand orders, cooperate with humac balance system administrations, and perform functional task training.
The selected children with GMFCS Level I and II were recruited to participate in this study. They can perform better in functional task training program that consists mainly of standing and walking activities. Level I children can walk alone but speed, balance, and coordination are limited. Long-distance walking and balancing on uneven or inclining terrain may be challenging for them. Level II Children need physical help when walking. Children's gross motor skills, such as running and jumping, are very limited [22].
The Gluteus medius muscle was selected for the application of FES in this study as it is mainly involved in the hip strategy of balance control. There are three strategies that have an important role in balance and postural control (ankle strategy, hip strategy, and step strategy). The hip strategy is intended to be used for quick or large amplitude perturbations, or when the support surface is narrow and very minimal ankle torque can be applied. It moves the body like a double-segment inverted pendulum with counter-phase motion at the ankle and hip [23]. The Previous study by Domínguez-Navarro et al. [24] emphasized that bilateral gluteus medius muscles are important in maintaining balance. Because these muscle groups are necessary for common movements such as lateral displacements, direction changes, and single-leg balance tasks.
In the current study, there were no significant differences between both groups in demographic data concerning age, sex, weight, height, GMFMCs, and spasticity which means that both groups are homogenous to avoid selection bias.
In this study, the preintervention mean values of static and dynamic balance (center of pressure and weight shift tests) in participating children for both groups showed a significant deficiency in static and dynamic balance values. This ensures that these children have significant balance problems. Raipure et al. [25] reported that spastic diplegic children have balance problems. That has an impact on their functional level, especially when they stand and walk, which might cause atypical motor behavior.
The results of both control and study groups were statistically significant and this may be due to effects of functional task rehabilitation that involves repetition of movements. It was suggested that muscle weakness and spasticity may be reduced with repetitive motor exercise. Furthermore, it serves as the physiological basis for motor learning, and sensorimotor coupling aids in the adaptation and reconfiguration of neural networks. In addition to repeated motor performance, involvement of active cognition, functional training, and performance are essential factors to enhance motor learning [26].
Functional-task training includes a variety of exercises. These variations improve motor learning since they cause relatively long-lasting changes in movement capability which is another name for motor learning. Functional-task training has a longer-lasting effect on motor performance [27]. Active participation, skill/exercise progression, and intense, structured practice are the fundamental components of motor learning; these principles were implemented in the current study. Also, the result of functional task training programs with electrical stimulation on standing and walking domains of GMFM scores showed significant differences in favor of the study group. These results may be explained by Surana et al. [28] who stated that the aims of functional task training were improving strength, balance, and coordination deficits of the lower extremities.
Statistical analysis of the two groups’ post-treatment findings showed significant enhancements in their functional ability and postural stability, which are characterized by maintaining an upright posture and good alignment of the body segments. It was expressed by improvement in humac balance system values. these results agreed with Merino-Andrés et al., [29] who studied the effect of strength training in cerebral palsy subjects in the pediatric age group and found positive effects on muscle strength of lower limbs, standing, walking, and balance abilities, with no increase of spasticity in these children, it has a great improvement in Gross Motor Function Classification System levels I and II when adequate dosage and specific principles are utilized.
The results of motor, COP, and weight shift post-intervention after successive 8 weeks of training showed a significant difference in favor of the study group; this may be due to the combined effects of functional task training with electrical stimulation. This is supported by Pool et al. [30] who demonstrated that performance improvements occur more quickly when muscle training is integrated into functional task activities as opposed to training done separately from the functional activity. Functional electrical stimulation may influence plastic changes in neuronal structures, and increased activation of primary sensory and motor areas [31]. Microvascular perfusion in the activated skeletal muscle can be increased by using NMES when combined with exercise. This improves physiological muscle function by reducing the diffusion distance in the activated muscle tissue and enhancing the flow of nutrients and metabolites between the blood and tissue. Additionally to its essential function on muscle tissue (preserving steady glucose metabolism), NMES may also enhance an individual’s general quality of life at all GMFM domains [32].
Using the NMES programs for pediatric conditions with chronic neurological disorders has a beneficial effect in enhancing muscle strength, movement biomechanics, spasticity, muscle architecture, body composition, and functional mobility associated with daily living. These effects enhance child development [33].
While there were significant improvements in all measuring variables in this study, there were certain limitations to verifying these findings; the sample was limited to 30 participants of spastic diplegia with level I and II on GMFCS. It is recommended that further studies utilizing large sample sizes with different GMFCS levels in different types of CP, longer study durations, using different objective evaluative materials, and follow-up are required.
Conclusion
This prospective study demonstrated the beneficial effects of functional task training with electrical stimulation on motor function and balance in children with diplegia. Therefore, this program may be applied in their rehabilitation because it is an efficient, applicable, and noninvasive approach.
