Cureus 2023; 15:e49802.

Abstract
Cerebral palsy (CP) encompasses a range of conditions that impact an individual's mobility, balance, and posture, making it the most prevalent motor impairment in children. In spastic cerebral palsy, muscle stiffness hinders walking and, if left untreated, may lead to complications such as hip dislocations or dysplasia. Adductor spasticity is a common challenge in these children, significantly impeding mobility and daily activities. The risk of hip dislocation escalates as gross motor function declines, particularly in children with severe impairments. This case report highlights the successful application of bilateral adductor tenotomy with gracilis release in a 9-year-old child diagnosed with spastic cerebral palsy, exhibiting a scissoring and in-toeing gait. Additionally, this report prompts consideration of the potential benefits of gracilis release in addressing the in-toeing gait observed in children affected by spastic cerebral palsy.

A pilot study on lengthening potentials and biomechanical effects of double and triple hemisection on tendon with slide lengthening. Sci Rep 2023; 13:3922. [PMID: 36894616 PMCID: PMC9998391 DOI: 10.1038/s41598-023-30791-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Accepted: 03/01/2023] [Indexed: 03/11/2023] Open
Abstract
The current study explored the slide-lengthening potentials of double and triple hemisections and the biomechanical effects of different inter-hemisection distances. Forty-eight porcine flexor digitorum profundus tendons were divided into double- and triple-hemisection groups (Groups A and B) and a control group (Group C). Group A was divided into Group A1 (distance between hemisections were the same as Group B) and Group A2 (distance between hemisections corresponded to the greatest distance between hemisections in Group B). Biomechanical evaluation, motion analysis, and finite element analysis (FEA) were performed. Failure load of intact tendon was significantly highest among groups. When the distance was 4 cm, the failure load of Group A increased significantly. When the distance between the hemisections was 0.5 or 1 cm, the failure load of Group B was significantly lower than Group A. Tendon elongation and failure load of Group B were significantly lower than those in Group A when the greatest distance between hemisections was the same. Consequently, Double hemisections had a similar lengthening ability to that of triple hemisections with the same distance, but better when the distances between extreme hemisections matched. However, the driving force for the initiation of lengthening may be greater.

Abstract
The effect of a continuous intrathecal infusion of baclofen (CITB) was retrospectively studied in 19 ambulatory children with cerebral palsy (aged 12.4±4.9 years at CITB initiation). The mean clinical follow-up was 5.1±2.4 years and the mean follow-up gait analysis was 2.8±1.9 years. Spastic cerebral palsy diagnosis [14 (74%)] was most frequent. Most patients [11 (58%)] were Gross Motor Function Classification System level III. CITB significantly improved muscle tone and knee flexion at initial contact (P<0.05), but it did not lead to improved gait speed or gross motor function.

Abstract
With advances in obstetric and perinatal management, the incidence of intraventricular hemorrhage in premature infants has declined, while periventricular leukomalacia remains a significant concern. It is now known that brain injury in children born preterm also involves neuronal-axonal disease in supratentorial and infratentorial structures. The developing brain is especially vulnerable to white matter (WM) injury from 23 to 34 weeks gestation when blood vessels serving the periventricular WM are immature. Oligodendrocyte progenitors, which are beginning to form myelin during this time, are susceptible to attack from oxygen free radicals, glutamate, and inflammatory cytokines. Advances in imaging techniques such as diffusion tensor imaging provide a more complete picture of the location and extent of injury. Effective management of children born preterm with cerebral palsy is predicated on an understanding of sequential links from etiological antecedents to brain neuropathology as revealed with neuroimaging techniques to clinical phenotypes, toward focused interventions with measurable outcomes.

Abstract
Cerebral palsy (CP) is a non progressive, demyelinating disorder that affects a child's development and posture and may be associated with sensation, cognition, communication and perception abnormalities. In CP, cerebral white matter is injured resulting in the loss of oligodendrocytes. This causes damage to the myelin and disruption of nerve conduction. Cell therapy is being explored as an alternate therapeutic strategy as there is no treatment currently available for CP. To study the benefits of this treatment we have administered autologous bone marrow mononuclear cells (BMMNCs) to a 12-year-old CP case. He was clinically re-evaluated after six months and found to demonstrate positive clinical and functional outcomes. His trunk strength, upper limb control, hand functions, walking stability, balance, posture and coordination improved. His ability to perform activities of daily living improved. On repeating the Functional Independence Measure (FIM), the score increased from 90 to 113. A repeat positron emission tomography-computed tomography (PET-CT) scan of the brain six months after intervention showed progression of the mean standard deviation values towards normalization which correlated to the functional changes. At one year, all clinical improvements have remained. This indicated that cell transplantation may improve quality of life and have a potential for treatment of CP.

Abstract
BACKGROUND Spasticity is the major etiology for hip dislocation in nonambulatory cerebral palsy patients. Selective dorsal rhizotomy (SDR) was used to control lower extremity spasticity, but is now done infrequently in nonambulatory cerebral palsy. Current surgical treatment is usually intrathecal baclofen pump (ITBP) placement. A major theoretical difference between SDR and ITBP is the effect on the iliopsoas through the L1 nerve root. This study compares the rate of hip dislocation and the need for further hip surgeries in SDR and ITBP patients. METHODS All nonambulatory cerebral palsy patients who had either an SDR or ITBP and had minimum follow-up of 2 years were retrospectively reviewed for demographic data and timing, total number, and type of hip procedures (soft tissue vs. bony), and occurrence of hip dislocation. χ (2)test was used to assess for statistical significance. RESULTS Sixty-nine patients who underwent SDR (40 males) and 50 patients who underwent ITBP (27 males) were included in the study. Average age at spasticity intervention was 6 years 11 months for SDR and 9 years 8 months for ITBP. In the SDR group, 25% of hips underwent reconstruction versus 32% of hips in the ITBP group. There were a total of 19 hip procedures in the SDR group and 20 in the ITBP group (P = 0.15). Seventeen soft-tissue procedures were performed in both SDR and ITBP groups (P = 0.265). Six bony procedures (0 salvage) were performed in the SDR group and 10 in the ITBP group (4 salvage; P = 0.075). At final follow-up the hip dislocation rate was 10.6% in the SDR group and 7.4% in the ITBP group. CONCLUSIONS There was no significant difference in the rate of secondary hip reconstructive surgery or dislocation between nonambulatory cerebral palsy patients who underwent SDR versus ITBP. Reconstruction was required for 25% to 32% of hips despite spasticity intervention with either procedure. This suggests that the L1 nerve root alone does not play a major role in the progression of hip dislocation. LEVEL OF EVIDENCE Level 3--therapeutic study.

Abstract
OBJECTIVE The objective was to assess the outcome of selective motor fasciculotomy in relieving upper limb harmful resistant spasticity and thereby to improve motor functions in persons with cerebral palsy. MATERIALS AND METHODS Twenty people having cerebral palsy (12 females and 8 males) with age ranging from 5 to 35 (mean 12.85) years with upper limb resistant spasticity due to spastic hemiplegia (n=7), triplegia (n=6), and quadriplegia (n=7) were assessed using Modified Ashworth Scale, Selective Voluntary Control Grade, Wee FIM Scale and hand function evaluation. Selective motor fasciculotomy was performed on the musculocutaneous nerve (n=13) for elbow flexors spasticity, median nerve (n=24) for pronators and radial wrist flexors spasticity and ulnar nerve (n=3) for ulnar wrist flexors spasticity. Pre- and post-op therapeutic exercises were performed. RESULTS Statistical analysis using the Wilcoxon Signed Ranks test showed significant reduction in spasticity and improvement in selective voluntary control, hand functions (grasp to hold a 2 inch rod), and Wee FIM (self-care domain in particular). There was no recurrence in spasticity and complications following surgery. CONCLUSIONS The selective motor fasciculotomy of musculocutaneous, median, and ulnar nerves significantly reduces spasticity in the affected muscle groups and thereby improves the self-care (motor) functions in selected people with cerebral palsy who have harmful resistant spasticity without any organic shortening of the muscles. The procedure is safe and the spasticity does not recur.

Abstract
AIM The aim of this retrospective analysis was to determine the impact of intrathecal baclofen (ITB) therapy on motor function in patients with cerebral palsy (CP). METHOD We studied 37 patients (18 males, 19 females) with CP treated with ITB (mean age at implant 13 y 7 mo, SD 7 y). Eighteen patients were affected by spastic diplegia, 12 by spastic quadriplegia, six by dystonic quadriplegia, and one by hemidystonia. Nine participants were in Gross Motor Function Classification System (GMFCS) level II, 13 in level III, seven in level IV, and eight in level V. Motor function was assessed by the Gross Motor Function Measure (GMFM) before the treatment and 12 months after the implant. RESULTS The collected data showed an increase in the total median GMFM score in the overall population (p<0.001) and in every GMFM dimension (p<0.05) except for dimension D (standing). The analysis by degree of impairment revealed that patients with severe impairment and those with mild to moderate impairment improved the total median GMFM score (p<0.001 and p<0.05 respectively). Analysis by age showed that the best improvements in GMFM scores were reached by patients younger than 18 years old (p<0.05). Spasticity and dystonia, assessed by means of the Ashworth and Barry-Albright Dystonia scales, significantly decreased 12 months after the implant (p<0.001 and p<0.05 respectively). Finally, a subjective questionnaire administered to patients/caregivers revealed an overall improvement in participants' functional abilities. INTERPRETATION The results suggest that ITB therapy is an effective treatment for managing spasticity and dystonia, and for improving motor function in children with CP.

Abstract
Despite advances in aneurysm ablation and the initial management of patients presenting with aneurysmal subarachnoid hemorrhage, delayed cerebral ischemia remains a significant source of morbidity. Traditionally, delayed cerebral ischemia was thought to be a result of vasospasm of the proximal intracranial vessels, and clinical trials have relied largely on radiographic evidence of vasospasm as a surrogate for functional outcome. However, a number of trials have demonstrated a dissociation between angiographic vasospasm and outcome, and more recent data suggest that other mechanisms of injury, such as microvascular dysfunction and complex neuronal-glial interactions, may influence the development of delayed ischemic deficit after aneurysmal subarachnoid hemorrhage. Our evolving understanding of the pathophysiology of delayed cerebral ischemia may offer the opportunity to test new therapeutic strategies in this area and improve clinical trial design.

Abstract
BACKGROUND In children with spastic cerebral palsy, the range of motion of the ankle joint is often limited. Measurement of range of motion may be hampered by a non-rigid foot deformity. We constructed a hand-held instrument which allows measurements of static ankle angle and moment in children with cerebral palsy while correcting for foot deformity. This study aimed to test the reproducibility of the instrument and to use it for measuring ankle moment-angle characteristics in individual children who are typically developing and children with cerebral palsy. METHODS Ankle angles and moments were measured at five standardized positions in ten children who are typically developing and ten children with cerebral palsy. The intraclass correlation coefficient was calculated for test-retest reliability. For precision, the standard error of measurement and smallest detectable difference were determined. The ankle range of motion and the slope of the moment-angle curve were determined, both towards plantar flexion and dorsiflexion. FINDINGS The reproducibility study revealed a high reliability of the dynamometer at 5 repetitions (>0.97). Precision lies within 5 degrees for angle measurements and within 0.2 Nm for moment measurements. In the children with cerebral palsy, the range of motion towards dorsiflexion was 18 degrees lower and the slope of the moment-angle curve towards dorsiflexion was substantially higher. INTERPRETATION We developed a hand-held dynamometer which allows reliable and precise measurements of static ankle angle and moment in children with cerebral palsy. The hand-held dynamometer allows corrections of foot deformities and is qualified to reproducibly evaluate moment-angle characteristics in a clinical context.

Abstract
Children with spastic cerebral palsy commonly acquire lower extremity musculoskeletal deformities that at some point may need surgical correction. The authors present 58 children with spastic cerebral palsy who underwent selective percutaneous myofascial lengthening of the hip adductor group and the medial or the lateral hamstrings. All the patients were spastic diplegic, hemiplegic, or quadriplegic. The indications for surgery were a primary contracture that interfered with the patients' walking or sitting ability or joint subluxation. Gross motor ability and gross motor function of the children were evaluated using the gross motor function classification system (GMFCS) and the gross motor function measure (GMFM), respectively. The mean time of the surgical procedure was 14 minutes (range, 1 to 27 minutes). All patients were discharged from the hospital setting the same day after the operation. There were no infections, overlengthening, nerve palsies, or vascular complications. Three patients required repeat procedures for relapsed hamstring and adductor contractures at 8, 14, and 16 months postoperatively. At 2 years after the initial operation, all the children improved on their previous functional level; 34 children improved by one GMFCS level, and 5 children improved by two GMFCS levels. The overall improvement in mean GMFM scores was from 71.19 to 83.19.

Abstract
Among features of motor disorders in children, spasticity is associated with considerable morbidity and problems in care, particularly in severely affected patients. Intrathecal baclofen (ITB) has been increasingly used as a relatively specific treatment modality for spasticity. To date, most of the evidence for its use in paediatric patients has come from retrospective and uncontrolled studies, although randomised, controlled trials of screening ITB and ITB therapy itself have recently been published. This consensus statement on the use of ITB in paediatric patients with spasticity was developed on the basis of currently available evidence, with the aim of providing information for clinicians, promoting an expert opinion and a consistent approach to the management of these patients and emphasising the need for further prospective, large-scale studies.

Abstract
Cerebral palsy (CP) is the most prevalent physical disability in childhood and includes a group of disorders with varying manifestations. This article focuses on current and future intervention strategies for improving mobility and participation during the lifespan for ambulatory children with CP. The provision and integration of physical therapy and medical and orthopedic surgery management focused primarily on the lower extremities are discussed here. Some of the newer trends are more intense and task-related exercise strategies, greater precision in tone identification and management, and a shift towards musculoskeletal surgery that focuses more on promoting dynamic bony alignment and less on releasing or lengthening tendons. Advances in basic and clinical science and technology development are changing existing paradigms and offering renewed hope for improved functioning for children with CP who face a lifelong disability with unique challenges at each stage in life.

Abstract
The case of a 51-year-old man diagnosed with two acquired cavernous hemangiomas 17 years after cranial irradiation for a cerebellar astrocytoma is reported. A review of 84 cases of radiation-induced cavernous hemangiomas found in the literature is presented. In this series the mean age at the time of irradiation (+/- SD) was 10.4 +/- 2.0 years (median = 8 years), while the mean time to cavernous hemangioma diagnosis (+/- SD) was 10.3 +/- 1.9 years (median = 8 years). Time to cavernous hemangioma diagnosis was found to be inversely related to radiation dose. Hemorrhage from radiation-induced cavernous hemangiomas was found in 40.0% of patients, with an incidence of 3.9% per patient year. An inverse trend was identified between radiation dose and symptomatic presentation, cavernous hemangioma hemorrhage or surgical resection. This review of radiation-induced cavernous hemangiomas confirms that both younger patients and those who received a larger dose of radiation are at increased risk of radiation-induced cavernous hemangiomas. Our results suggest that, based on an assessment of CT or MR images, there may be an increased risk of hemorrhage when comparing radiation-induced to congenital cavernous hemangiomas. Increasing radiation doses appear to stabilize these lesions, decreasing the risk of a symptomatic presentation, cavernous hemangioma hemorrhage and surgical intervention.

Abstract
BACKGROUND AND PURPOSE Studying imaging findings of non-acquired immunodeficiency syndrome (AIDS) primary central nervous system lymphoma (PCNSL), we hypothesized that the imaging presentation has changed with the increasing incidence of PCNSL and is related to clinical factors (eg, time to diagnosis and the patient's being diagnosed alive or at postmortem examination). MATERIALS AND METHODS Chart and histologic reviews of patients recorded as having PCNSL during 1989-2003 in the Norwegian Cancer Registry identified 98 patients with non-AIDS PCNSL; 75 had available imaging. CT and MR images from the first diagnostic work-up after onset of symptoms but before histologic diagnosis were reviewed. RESULTS CT and/or MR imaging in the 75 patients revealed no lesion in 10 (13%), a single focal lesion in 34 (45%), multiple focal lesions in 26 (35%), and disseminated lesions in 5 (7%) patients. All together, we identified 103 focal lesions (single/multiple): 63% in white matter, 56% abutting the ventricular surface, and 43% in the frontal lobes); 100% (102/102 lesions evaluated with contrast) showed contrast enhancement. The median time from imaging to diagnosis for patients with no, single, multiple, or disseminated lesions was 32, 3, 5, and 3 weeks, respectively (P = .01). Patients with no or disseminated lesions were more often diagnosed at postmortem examination (P = .06). Imaging findings were practically unchanged during the consecutive 5-year periods. CONCLUSIONS White matter periventricular contrast-enhancing single or multiple focal lesions were typical of non-AIDS PCNSL. No or disseminated lesions heightened the risk of delayed or postmortem diagnosis. Although the incidence of non-AIDS PCNSL has increased, its presentation at imaging remains unchanged.

Abstract
Gamma aminobutyric acid (GABA) is an inhibitor neurotransmitter that plays many important roles in the central nervous system. Because the half-life time of GABA is very short in vivo, GABA itself is not used for clinical practice. An analogue of GABA, baclofen, is an agonist of GABA-B receptor, and has very strong antispastic effect by acting to the posterior horn of the spinal cord. However, baclofen poorly crosses through the blood brain barrier, and the antispastic effect is modest when administered orally. Therefore, direct continuous infusion of small doses of baclofen into the cerebrospinal fluid (intrathecal baclofen therapy, ITB) has become an established treatment for control of otherwise intractable severe spasticity. Spasticity is clinically defined as hypertonic state of the muscles with increased tendon reflexes, muscles spasm, spasm pain, abnormal posture, and limitation of involuntary movements. Spasticity is a common symptom after damage mainly to the pyramidal tract system in the brain or the spinal cord. Such damage is caused by traumatic brain injury, stroke, spinal cord injury, multiple sclerosis, and so on. Patients in persistent vegetative state (PVS) usually have diffuse and widespread damage to the brain, spasticity is generally seen in such patients. Control of spasticity may become important in the management of PVS patients in terms of nursing care, pain relief, and hygiene, and ITB may be indicated. Among PVS patients who had ITB to control spasticity, sporadic cases of dramatic recovery from PVS after ITB have been reported worldwide. The mechanism of such recovery of consciousness is poorly understood, and it may simply be a coincidence. On the other hand, electrical spinal cord stimulation (SCS) has been tried for many years in many patients in PVS, and some positive effects on recovery of consciousness have been reported. SCS is usually indicated for control of neuropathic pain, but it has also antispastic effect. The mechanism of SCS on pain is known to be mediated through the spinal GABA neuronal system. Thus, ITB and SCS have a common background, spinal GABA neuronal mechanism. The effect of GABA agonists on recovery of consciousness is not yet established, but review of such case studies becomes a clue to solve problems in PVS, and there may be hidden serendipity.

Abstract
In children with spasticity, deep tendon reflexes are hyperactive and even stimulation of normal dorsal rootlets can produce exaggerated full-strength, single-twitch responses in the muscles they innervate. This phenomenon is called the brisk hyperactive response (BHR). The aim of this study was to compare the efficacy of 2 volatile anesthetics, isoflurane and sevoflurane, for suppressing the confounding effect of BHR during selective dorsal rhizotomy (SDR) in children with spasticity. The subjects were 54 consecutive children of American Society of Anesthesiology physical status III who were scheduled for SDR. After tracheal intubation, each child was randomly assigned to Group I (isoflurane; n=27) or Group S (sevoflurane; n=27). There was no significant difference between the mean operation times in Groups I and S (200+/-40 vs. 220+/-35 minutes, respectively; p=0.0559). Thirteen patients in Group I (48.1%) and 5 in Group S (18.5%) exhibited BHR during stimulation of the dorsal rootlets (odds ratio 4.086; p=0.0418). Three of these 18 patients (2 in Group I and 1 in Group S) experienced hypertension and tachycardia simultaneously with BHR (odds ratio 4.086; p=1.0). The results suggest that sevoflurane is more effective at preventing BHR and might be a better choice for anesthetic management of children with spasticity undergoing SDR.

Abstract
Selective dorsal rhizotomy at the lumbar level is a neurosurgical procedure, which reduces spasticity in the legs. Its effect has mainly been studied in children with spastic cerebral palsy. Little is known about the outcome of selective dorsal rhizotomy in patients with neurodegenerative disorders. We report the clinical course after selective dorsal rhizotomy in 2 patients with progressive spasticity. Leg spasticity was effectively and persistently reduced in both patients, facilitating care and improving sitting comfort. However, spasticity of the arms and other motor disturbances, such as spontaneous extension spasms and the ataxia, increased gradually in time. Selective dorsal rhizotomy leads to a disappearance of leg spasticity in patients with a neurodegenerative disease. Other motor signs are not influenced and may increase due to the progressive nature of the underlying disease.

Abstract
BACKGROUND The literature shows that intrathecal baclofen (ITB) treatment in patients with cerebral palsy (CP) is able to reduce spasticity. The purpose of this work is to evaluate the motor function of the upper limbs in patients with CP treated with ITB. METHODS A consecutive series of 20 patients with spastic CP (mean age at implant, 11.4 years) implanted with pumps in our center was studied. These patients were classified using the Gross Motor Function Classification System. The patients were followed up over a 12-month period for assessment of the upper limb function with the Melbourne Assessment of Unilateral Upper Limb Function scale. RESULTS The data show a reduction of upper limb spasticity in all 20 patients (P < 0.05). The Melbourne scale shows a statistically significant improvement of the total score (P < 0.05) and an improvement of the subskills of range of movement, target accuracy, and fluency. Twenty-five percent of patients showed a clinically significant improvement. CONCLUSION The subjects with CP of different degrees of severity had an improvement in the quality of the upper limb function and showed overall satisfaction with the results achieved. The study also shows the importance of evaluating the quality of upper limb function in children with CP treated with ITB therapy.

Abstract
OBJECTIVES Selective dorsal rhizotomy (SDR) has been widely performed for the reduction of spasticity in patients with cerebral palsy during the past 2 decades. The objective of this study was to determine whether the surgery has yielded long-term functional benefits for these patients. METHODS The authors present results from a prospective 20-year follow-up study of locomotor function in 13 patients who underwent an SDR in 1985. For comparison, we also present gait data for 48 age-matched healthy controls (12 at each of 4 time points). Patients were studied preoperatively and then at 1, 3, 10, and 20 years after surgery. Study participants were recorded in the sagittal plane while walking using a digital video camera, and 6 standard gait parameters were measured. RESULTS In this group of patients 20 years after surgery, knee range of motion (ROM) was on average 12 degrees greater than preoperative values (p < 0.001). Hip ROM before surgery was no different from that in the healthy control group. This parameter increased markedly immediately after surgery (p < 0.001) but had returned to normal after 20 years. The knee and hip midrange values-a measure of the degree of "collapse" due to muscle weakness after surgery-had returned to preoperative levels after 20 years, although they were respectively 11 and 8 degrees greater than those in healthy controls. Both temporal-distance parameters (dimensionless cadence and dimensionless step length) were significantly greater at 20 years than preoperative values (cadence, p = 0.003; step length, p = 0.02), leading to improved walking speed. CONCLUSIONS Twenty years after undergoing SDR, our patients showed improved locomotor function compared with their preoperative status.

Abstract
OBJECT The authors investigated the efficacy of intrathecal baclofen therapy, analyzing the complications and risk factors in 200 consecutive patients who received pump implants. METHODS The patient population included 200 patients (mean age 13.7 +/- 5.68 years). The follow-up duration varied from 13.07 to 87.50 months (mean 50.71 months). RESULTS The mean Ashworth Scale, Barry-Albright Dystonia Scale, clonus, and spasm scores decreased postoperatively. Overall, 31% of patients experienced complications as follows: 11% had cerebrospinal fluid leakage, 7% had catheter-related problems, 7.5% suffered infections; 5.5% of patients had more than one complication. CONCLUSIONS The authors found that the onset of at least one complication is statistically more likely in patients with Ashworth Scale scores higher than 3 and an age of 10 years or younger. A reduction in the incidence of infection from 10 to 4.8% by the end of the study period appears to be correlated with the switch in technique to subfascial instead of subcutaneous pump implantation and the adoption of a new preoperative prophylaxis protocol in the last 51 patients. There were no statistically significant correlations between the onset of complications and patient weight, ambulatory status, or the presence of dystonia or cerebral palsy.
