Optimization of Postural Control, Balance, and Mobility in Children with Cerebral Palsy: A Randomized Comparative Analysis of Independent and Integrated Effects of Pilates and Plyometrics.

The paradigm of comprehensive treatment approaches for children with cerebral palsy has gained traction, prompting clinicians to deliberate between independent and integrated treatment delivery. However, this decision-making process is often hindered by the dearth of empirical evidence available to inform optimal therapeutic strategies. This study, therefore, sought to compare the effects of Pilates-based core strengthening (PsCS), plyometric-based muscle loading (PlyoML), and their combination on postural control, balance, and mobility in children with unilateral cerebral palsy (ULCP). Eighty-one children with ULCP (age: 12-18 years) were randomized to PsCS (n = 27), PlyoML (n = 27), or a combined intervention (n = 27; equated for total sets/repetitions) group. The three interventions were applied twice/week over 12 successive weeks. Postural control (directional and overall limits of stability-LoS), balance, and mobility (Community Balance and Mobility Scale-CB&M; Functional Walking Test-FWT; Timed Up and Down Stair test-TUDS) were assessed pre- and post-intervention. The combined group exhibited greater increases in directional LoS compared to PsCS and PlyoML including the backward (p = 0.006 and 0.033, respectively), forward (p = 0.015 and 0.036, respectively), paretic (p = 0.017 and 0.018, respectively), and non-paretic directions (p = 0.006 and 0.004, respectively)], and this was also the case for overall LoS (p < 0.001 versus PsCS and PlyoML). In addition, the combined group displayed greater improvements compared to the PsCS and PlyoML groups regarding CB&M (p = 0.037 and p = 0.002, respectively), FWT (p = 0.012 and p = 0.038, respectively), and TUDS (p = 0.046 and p = 0.021, respectively). In conclusion, the combined PsCS and PlyoML exercise program promotes considerably greater improvements in postural control, balance, and mobility compared to unimodal training in children with ULCP.

Effectiveness of a dose-graded aerobic exercise regimen on cardiopulmonary fitness and physical performance in pediatric survivors of acute lymphoblastic leukemia: a randomized clinical trial.

PURPOSE: To determine whether a 12-week supervised dose-graded aerobic exercise (D-GAE) training, when implemented in conjunction with traditional rehabilitation, could help pediatric survivors of acute lymphoblastic leukemia (ALL) enhance their cardiopulmonary capacity and improve their physical performance. METHODS: Fifty-eight pediatric survivors of ALL (age 13.78 ± 2.47 years; boys 60.34%) were assigned at random to either undergo the D-GAE in addition to the traditional physical rehabilitation (D-GAE group; n = 29) or the traditional physical rehabilitation solely (control group; n = 29). The cardiopulmonary fitness (peak oxygen uptake (VO2peak), ventilatory equivalent (VEq/VO2), minute ventilation (VE, L/min), oxygen pulse (O2P), maximum heart rate (HRmax), 1-min heart rate recovery (HRR1), and respiratory exchange ratio (RER)) and physical performance (6-min walk test (6-MWT), timed up and down stairs (TUDS), and 4 × 10-m shuttle run test (4 × 10mSRT)) were assessed on the pre- and post-intervention occasions. RESULTS: The mixed-model ANOVA revealed a meaningful increase of VO2peak (P = .002), VE (P = .026), O2P (P = .0009), HRmax (P = .004), and HRR1 (P = .011), and reduction of VEq/VO2 (P = .003) and RER (P = .003) in the D-GAE group compared with the control group. Besides, the analysis detected a favorable increase in the physical performance for the D-GAE group (6-MWT (P = .007), TUDS (P < .001), 4 × 10mSRT (P = .009)). CONCLUSION: A 12-week D-GAE program in conjunction with traditional rehabilitation holds promise in enhancing cardiopulmonary fitness and improving the physical performance of pediatric survivors of ALL. Clinicians and physical rehabilitation professionals can, therefore, integrate the D-GAE into the traditional rehabilitation protocols for such a patient population to optimize their cardiopulmonary fitness and physical function, while also facilitating a gradual transition to practice and adaption. IMPLICATIONS FOR CANCER SURVIVORS: The favorable outcomes of this study bolster the inclusion of D-GAE as a crucial element in the care and rehabilitation of pediatric survivors of ALL. By embracing these findings, healthcare professionals and oncologists can contribute to mitigating the long-term cardiopulmonary and physical complications associated with cancer treatments and fostering a state of enhanced well-being and increased physical activity among survivors.

The rationale of applying inspiratory/expiratory muscle training within the same respiratory cycle in children with bronchial asthma: a placebo-controlled randomized clinical investigation.

OBJECTIVE: Even though positive implications of inspiratory muscle training (In-MT) have been established in children and adolescents with bronchial asthma (C/AwBA), the role of combined inspiratory and expiratory muscle training (Ex-MT) within the same respiratory cycle (In/Ex-SC) is still unknown. This study was, therefore, set out to explore the effect of In/Ex-SC on respiratory muscle strength, pulmonary functions, and control of asthma symptoms in C/AwBA. METHODS: This was a placebo-controlled randomized clinical investigation that included 51 C/AwBA (12-18 years). Participants were assigned randomly into three groups: Placebo, In-MT only, or combined In/Ex-SC training (n = 17, each group). The training was conducted for ∼35 min, thrice/week over 12 weeks. The maximal inspiratory (IPmax) and expiratory (EPmax) pressure (indicating the strength of the inspiratory and expiratory muscles, respectively), pulmonary functions [forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC index], and asthma control test (ACT) were assessed before and after the intervention. RESULTS: The In/Ex-SC yielded larger increases in IPmax and EPmax than either the Placebo training (P=.031 and P=.009 respectively) or the In-MT (P=.029 and P=.032 respectively). Further, In/Ex-SC produced favorable improvement in FEV1, FVC, and FEV1/FVC compared to the Placebo training (P=.001, P=.004, and P=.0005 respectively) or In-MT (P=.038, P=.037, and P=.025 respectively) training. Furthermore, In/Ex-SC led to better control of asthma symptoms than the Placebo (P<.001) or In-MT (P=.002) training. CONCLUSION: This study provides evidence that combined In/Ex-SC can considerably improve respiratory muscle strength, enhance pulmonary function, and promote control over asthma symptoms in C/AwBA.

Stretch-shortening cycle exercises can efficiently optimize gait-symmetry and balance capabilities in children with unilateral cerebral palsy: A randomized controlled trial.

BACKGROUND: Children with unilateral cerebral palsy (UCP) experience an asymmetrical gait pattern and poor balance capabilities. Effective interventions, therefore, are needed to facilitate remediation of these functional issues. OBJECTIVE: This study was set out to investigate the emerging role of stretch-shortening cycle (SSC) exercises on gait-symmetry and balance in children with UCP. METHODS: In this randomized controlled trial, 42 children with UCP (age; 8 -12 years) were enrolled and received either standard physical rehabilitation (control group; n = 21) or the SSC exercise program plus physical rehabilitation (SSC group; n = 21). Spatial- and temporal-gait symmetry index (GSI) and specific balance capabilities [reactive balance, directional control, movement synchronization, and sensory organization] were assessed before and after 16 sessions that were carried out twice/week over non-sequential days in an 8-week program. RESULTS: Using the pre-treatment scores as covariates, the post-treatment spatial- (P = 0.006; ηp2= 0.17) and temporal- GSI (P < .001; ηp2= 0.46) scores reduced significantly in the SSC group as compared to the control group, suggesting favorable improvement of gait symmetry. Also, all measures of balance (P < 0.05; ηp2 ranged between 0.10 and 0.29) improved remarkably, post-treatment, in SSC group in comparison with the control group. CONCLUSION: The evidence from this study suggests that SSC exercises besides standard physical rehabilitation appear to be effective for improving gait symmetry and boosting balance capabilities in children with UCP.

Functional outcomes of botulinum neurotoxin-A injection followed by reciprocal electrical stimulation in children with cerebral palsy: A randomized controlled trial.

BACKGROUND: The integration of therapeutic approaches is increasingly recommended for children with cerebral palsy, to enhance outcomes. Nevertheless, clinicians still opt for separate or combined therapies based on little credible knowledge. OBJECTIVE: This study endeavored to evaluate the effect of botulinum neurotoxin-A (BoNT-A) injection and reciprocal neuromuscular electrical stimulation (rNMES) and their combination on the upper extremity function in children with spastic hemiplegia. METHODS: Sixty-four children with spastic hemiplegia (aged 6- 10 years) were randomly assigned to four treatment-based groups [group I (BoNT-A), group II (rNMES), group III (combined BoNT-A and rNMES), and group IV (Control)]. All children received a physical rehabilitation program, thrice/week over three months. Unilateral upper-limb function, bimanual hand function, and real-time arm-hand function were assessed using Melbourne Assessment (MA), Assisting Hand Assessment (AHA), and Pediatric Motor Activity Log (PMAL) scales respectively pre-treatment, post-treatment, and at 6 months follow-up. RESULTS: Post-treatment, group III achieved greater improvement in MA, AHA, and PMAL compared to other groups (all P < 0.05), and the difference remained in favor of group III at the follow-up (all P < 0.05). CONCLUSIONS: This study suggests that BoNT-A and rNMES combined are more effective than either of them alone to enhance upper-extremity function in children with spastic hemiplegia.

Plyometric exercises: subsequent changes of weight-bearing symmetry, muscle strength and walking performance in children with unilateral cerebral palsy.

OBJECTIVE: To evaluate the subsequent effects of plyometric training on weight-bearing symmetry, muscle strength, and gait performance in children with unilateral cerebral palsy. METHODS: Thirty-nine children with spastic hemiplegia (age 8-12 years) were randomly divided into either the PLYO group (n=19, received a 30-minute plyometric exercise program plus the traditional physical rehabilitation, twice/week for eight consecutive weeks) or Non-PLYO group (n=20, received the traditional physical rehabilitation only). The weight-bearing symmetry index (WB-SI), maximum isometric muscle strength (MIMS) of quadriceps and hamstring muscles, and spatial-temporal gait parameters were assessed pre and post-intervention. RESULTS: From pre- to post-intervention, changes of WB-SI among PLYO and Non-PLYO groups did not differ significantly (P=.81; hindfoot and P=.23; forefoot). MIMS of quadriceps and hamstring muscles at 90° knee flexion (P=.008 and .013 respectively) increased significantly in PLYO compared to Non-PLYO group. Walking speed (P=.033), stride length (P=.002), and step time (P<.001) improved markedly in PLYO group more than in Non-PLYO group. The proportion of single leg support (P=.14) among PLYO and Non-PLYO groups did not differ significantly. CONCLUSION: Addition of plyometric exercises to the physical rehabilitation programs of children with unilateral CP could achieve greater improvement in muscles strength and walking performance, but not in WB-SI.

Evaluation of independent versus integrated effects of reciprocal electrical stimulation and botulinum toxin-A on dynamic limits of postural stability and ankle kinematics in spastic diplegia: a single-blinded randomized trial.

BACKGROUND: Combination of medical and physical therapy protocols are increasingly recommended for cerebral palsied children. However, the clinicians frequently choose between independent or integrated treatment delivery based on little empirical evidence. AIM: The aim of this study was to analyze the independent versus the integrated effects of reciprocal electrical stimulation (RES) and botulinum toxin-A (BoNT-A) in terms of dynamic limits of postural stability and ankle kinematics in spastic diplegia. DESIGN: A single-blinded randomized trial. SETTING: Physical therapy laboratories and out-patient clinic and a tertiary local hospital. POPULATION: Sixty children with spastic diplegia were allocated to RES, BoNT, or Integrated RES and BoNT interventions (20 children for each group). METHODS: All children participated in a 60-minutes exercise program, three times/week for 12 successive weeks. Additionally, The RES group received reciprocal electrical stimulation of ankle dorsi and plantar flexors for 30 minutes before each exercise session, the BoNT group were injected by botulinum toxin-A to calf muscles one-week prior to commencing the exercise program, and the Integrated RES and BoNT group received both interventions. Ankle joint kinematics (displacement angle at initial contact, maximum dorsiflexion-stance, and peak dorsiflexion-swing) and dynamic limits of postural stability (anterior/posterior [AP-LOS], medial/lateral [ML-LOS], and overall [O-LOS]) were assessed at entry and after intervention. RESULTS: Study groups were comparable with respect to all outcome measures at entry (P>0.05). Compared to the independent effect of either RES or BoNT-A, the integrated RES and BoNT-A produced a preferable improvement of O-LOS, maximum dorsiflexion-stance, and peak dorsiflexion-swing subsequently after intervention (P<0.05). Further, significant differences between BoNT-A and RES regarding the AP-LOS and ML-LOS were observed in favor of BoNT-A (P<0.05). CONCLUSIONS: Integration of RES and BoNT-A has the capability to restore postural stability and ankle kinematics in diplegic children. CLINICAL REHABILITATION IMPACT: Integration of RES and BoNT-A has a considerable effect on some of the essential elements that contribute toward the improvement of ankle biomechanics and postural stability. The demonstrated effect provides the basis for its application in the treatment of spastic diplegia.
