- Covering a 20-year period of work with children with severe cerebral palsy (CP) within a Swedish habilitation service, changes in passive wrist extension with fingers extended (PWE-FE) and current hand function are described and compared between children receiving systematic upper-extremity treatment with botulinum neurotoxin type A and intervention programs from before 7 years of age (Group 1, n = 7), those whom for various reasons did not undergo this treatment (Group 2, n = 10), and those not having the option to receive treatment until later during childhood/adolescence (Group 3, n = 8). Group 3 showed more critical and less normal PWE-FE values for both wrists, and poorer hand function scores, particularly compared with Group 1. Findings cautiously suggest that repeated upper-extremity spasticity-reducing treatment and movement training/orthoses from an early age may help prevent critical loss of passive range of motion of the wrist joint flexion/extension and promote hand function development in children with severe CP.

- OBJECT: The dyskinetic subtype of cerebral palsy is difficult to manage, and there is no established gold standard for treatment. External rotation of the shoulder(s) is often managed nonsurgically using injections of botulinum toxin A into the external rotator muscles. This article reports a new surgical technique for managing external rotation when botulinum toxin A treatment is not sufficient or possible.METHODS: Six patients with dyskinetic cerebral palsy underwent denervation of the infraspinatus muscle and release of the posterior part of the deltoid muscle. Postoperative questionnaires were given to the patients/caregivers, and video recordings were made both pre- and postoperatively. Preoperative and postoperative Assisting Hand Assessment was possible in only 1 case.RESULTS: Five patients were very satisfied with their outcome. Four patients' video recordings showed improvement in their condition. One patient developed postoperative complications.CONCLUSIONS: The results indicate that denervation of the infraspinatus muscle and posterior deltoid release can be an option for patients with dyskinetic cerebral palsy to manage external rotation of the shoulder when other treatment alternatives are insufficient.

- Botulinum toxin A (BoNT-A) injections for treatment of spasticity in patients with cerebral palsy (CP) have been used for about two decades. The treatment is considered safe but a low frequency of adverse events (AE) has been reported. A good method to report AEs is necessary to verify the safety of the treatment. We decided to use an active surveillance of treatment-induced harm using a questionnaire we created. We studied the incidence of reported AEs and side effects in patients with CP treated with BoNT-A. We investigated the relationship between the incidence of AEs or side effects and gender, age, weight, total dose, dose per body weight, Gross Motor Function Classification System (GMFCS) and number of treated body parts. Seventy-four patients with CP participated in our study. In 54 (51%) of 105 BoNT-A treatments performed in 45 (61%) patients, there were 95 AEs and side effects reported, out of which 50 were generalized and/or focal distant. Severe AEs occurred in three patients (4%), and their BoNT-A treatment was discontinued. Consecutive collection of the AE and side-effect incidence using our questionnaire can increase the safety of BoNT-A treatment in patients with CP.

Upper limb assessment and treatment in cerebral palsy

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Cerebral palsy (CP) is a heterogeneous group of neurological disorders caused by fetal or infant brain damage that often involves deficits in upper limb (UL) posture and function. Knowledge about effective methods of assessment and treatment of UL in CP is not extensive. In this thesis, different aspects of these two are explored.In Paper I we retrospectively investigated the effect of a long-term treatment regime developed in Västerbotten county habilitation service. The treatment regime included intramuscular injections of botulinum toxin type A (BoNT-A) combined with occupational therapy (OT) and movement training. The results of passive extension of the wrist with fingers extended and the assessment of hand function in children with severe hand function impairment (initially House functional classification 0-1) were analyzed over time. Twenty-five children were divided into 3 groups depending on the treatment regime start age (before or after the age of 7) and treatment regime availability. We found significantly worse passive extension of the wrist with fingers extended in children who did not have a chance to benefit from therapy in early childhood. Additionally, an improvement in the passive movement of the wrists was noted in children who completed the treatment regime before the age of 7. Regarding hand function, a significant difference was found between children who received treatment in early childhood and those who received treatment as adolescents.The injections of BoNT-A in CP are common, however the monitoring of eventual side effects and adverse events (AEs) after this treatment is difficult to perform in clinical practice. To facilitate this process, we created a new, no previously validated questionnaire (Paper II). The questionnaire was given to patients or their caregivers to be completed after each BoNT-A treatment. 94% of participants returned the questionnaire. 80 % were filled in completely which proves the effectiveness of the applied form and the ease of its use in clinical practice. 61% of patients reported one or more different AEs or sides effects. In addition, we analyzed the risk for generalized and focal distal AEs reported by 38% of patients. Those may indicate the spread of BoNT-A toxin to the whole body, therefore requiring special attention. We found that females had a 1.899 relative risk with significant association (p=0.029) of reporting generalized and focal delayed AEs compared to males. The use of the questionnaire helped to make the decision to change or discontinue BoNT-A injections in 8 cases (11%).In some patients with dyskinetic type of CP (DCP) treated with BoNT-A to diminish the external rotation posture of the shoulders, a loss of treatment effect was observed, which contributed to the need to look for another method of treatment. In paper III, a surgical method to manage the external rotation posture of the shoulders is presented. The surgical procedure consists of weakening the strength of the externally rotating muscles by cutting the attachment of one of them (release of the posterior deltoid) and complete denervation of the other (denervation of the infraspinatus). The third shoulder external rotator (teres minor) remains intact. The results of this procedure performed in 7 shoulders in 6 patients (age 14-24) were analyzed using satisfaction questionnaire and pre-/postoperative video-recordings. Five of 6 patients were very satisfied with the treatment, one was neither satisfied nor dissatisfied. Four patients had an obvious improvement in their shoulder position confirmed on video recordings. In one, overcorrection in the form of internal shoulder rotation was observed.Assessment of the thumb in CP is important as the thumb impairment plays a crucial role in hand grip function. Paper IV presents a new tool called CP-thumb score, which addresses the occupational therapists to follow the changes in the thumb function and its posture. CP-thumb score has two parts: descriptive and score of the thumb’s CMC joint radial abduction. Thirty thumbs in 19 patients with all types of CP were assessed with CP-thumb score. All assessments were made based on available video recordings. Additionally, all thumbs were assessed using the House’s thumb-in-palm classification which has been shown to be unreliable. These two thumb assessments were compared with each other.

- PIK3CA-related overgrowth spectrum is a group of rare genetic disorders with asymmetric overgrowth caused by somatic mosaic PIK3CA mutations. Here, we report clinical data and molecular findings from two patients with congenital muscular upper limb overgrowth and aberrant anatomy. During debulking surgery, numerous ectopic muscles were found in the upper limbs of the patients. DNA sequencing, followed by digital polymerase chain reaction, was performed on DNA extracted from biopsies from hypertrophic ectopic muscles and identified the somatic mosaic PIK3CA hotspot mutations c.3140A > G, p.(His1047Arg) and c.1624G > A, p.(Glu542Lys) in a male (patient 1) and a female (patient 2) patient, respectively. Patient 1 had four ectopic muscles and unilateral isolated muscular overgrowth while patient 2 had 13 ectopic muscles and bilateral isolated muscular overgrowth of both upper limbs, indicating that her mutation occurred at early pre-somitic mesoderm state. The finding of PIK3CA mutations in ectopic muscles highlights the importance of PIK3CA in cell fate in early human embryonic development. Moreover, our findings provide evidence that the disease phenotype depends on the timing of PIK3CA mutagenesis during embryogenesis and confirm the diagnostic entity PIK3CA-related muscular overgrowth with ectopic accessory muscles.
