Many people with neurological conditions will experience spasticity, a nonvolitional and uncontrollable tightening and/or spasm of muscles. This can impact the person's functioning and independence in everyday tasks and can contribute to contractures. Spasticity and contracture develop and affect each person differently. Treatment is provided by a multi-disciplinary team (MDT), working collaboratively to offer the best combination of medications (including botulinum neurotoxin (BoNT)) and non-pharmacological interventions. There are a wide range of therapy interventions available. Each person's treatment plan is uniquely tailored to them, their individual presentation, and their treatment goals. Evidencing the effectiveness of spasticity and contracture treatment has been difficult. The manifestation and treatment of spasticity is never the same between patients. The experience of the condition and the perceived and observable effectiveness of treatment are unique to the individual. Treatment is most effective when MDT's work together to combine the most appropriate medications and therapies in a treatment plan individualised to the person and their presentation. Understanding how expert teams formulate spasticity treatment and how effectively their expertise influences spasticity outcomes could help inform practice.
The purpose of this multicenter, case study series is to evaluate the effectiveness of two conceptually similar, specialised MDT approaches for the treatment of patients with spasticity in two cross-national neurorehabilitation facilities.
The goal of this study is to investigate the effectiveness of interprofessional treatments of non-drug interventions in combination with botulinum toxin injections in patients who suffer from spasticity.
The main goals of the study are to evaluate:
There will be no comparison group. The N-of-1, ABC study design allows participants to serve as their own controls.
Participants will undergo assessements to describe their goals and severity of spasticity:
Cross-national, multicenter (CH and UK) single case experimental design (SCED), specifically N-of-1 series with an ABC Design (Baseline, Intervention, Follow-up). Patients with focal or multifocal spasticity who the MDT determine that BoNT and concomitant therapies are appropriate interventions based on their multidisciplinary evaluation. As this is a trial with defined pharmacological and non-pharmacological interventions that are an integral part of the individual treatment, all measurements and treatments are included to varying degrees in the standard of care/usual care in the rehabilitation centres. Participants will receive their botulinum toxin and therapy treatments as recommended by their clinical team. Both are a standard care in rehabilitation of spasticity. Included patients receive their BoNT injection and non-pharmacological interventions as indicated. All participating patients will be repeatedly measured at baseline phase A (pre- intervention), during intervention phase B and after completion of the intervention during phase C follow-up. The repeated measurements at baseline allow the participants to serve as their own controls. With this method, the treatment efficacy for individual patients can be estimated, rather than aggregate group effects and therefore the true heterogeneity and varying responses of individual patients is captured.

| Spasticity-related quality of life (SQoL-6D): Influence of the MDT approach on Quality of Life (QoL) | Spasticity-related quality of life (SQoL-6D) provides an overall picture of spasticity-related health status following focal treatment of upper limb spasticity. As a valid, reliable and responsive measure of spasticity-related quality of life, the SQoL is designed to record those dimensions that relate to the chosen goal areas. There are six dimensions of the SQoL-6D:
| From enrollment: Baseline 2 weeks (4x), Intervention 12 weeks (6x), Follow-up 6 (1x) and 12 (1x) weeks after completion of intervention |
| Arm Activity Measure (ArmA): The influence on MDT approach on active or passive care of the affected limb | ArmA: It is a valid and reliable tool, which measures changes in passive and active function in the upper limb due to spasticity related impairment. It is a patient or carer rated outcome measure with 20 items relating to clinically relevant goals from the patient or carer's point of view. It is a 5-point Likert scale with 0 = no difficulties and 4 = not able to do. LegA: It is a valid and reliable tool, which measures change in passive and active function of the lower limb due to spasticity related impairment and the impact of these on quality of life. It is a patient or carer-rated outcome measure with 33 items relating to clinically relevant goals from the patient or carer's point of view. It is a 5 point Likert scale with 0 = no difficulties and 4 = not able to do. | From enrollment: Baseline 2 weeks (4x), Intervention 12 weeks (6x), Follow-up 6 (1x) and 12 (1x) weeks after completion of intervention |
| Modified Ashworth Scale (MAS): The influence of the MDT approach on spasticity | MAS: The MAS measures the severity of spasticity and is a six-point ordinal scale (0 - no difficulty, 4 - unable to do task) with an additional point at +1 (slight increase in muscle tone). The MAS therefore provides a single score to represent spasticity. It has moderate reliability but is widely used in clinical practice due to ease of application. | From enrollment: Baseline 2 weeks (2-4times), Intervention 12 weeks (weekly), Follow-up 6 (1x) and 12 weeks (1x) after completion of intervention |
| Modified Tardieu Scale (mTS): The influence of the MDT approach on spasticity | mTS: The mTS is a reliable measure which quantifies spasticity by assessing the muscle response to different stretch velocities (movements at fast and slow speed passive movement) and by determining the spasticity angle. Additionally, the quality of muscle reaction regarding resistance, clonus or contracture is noted. It is a 5-point ordinal scale with 0=no resistance and 4=clonus > 10sec. | From enrollment: Baseline 2 weeks (2-4times), Intervention 12 weeks (weekly), Follow-up 6 (1x) and 12 weeks (1x) after completion of intervention |
| The influence of the MDT approach on muscle strength | Muscle strength will be tested manually by the examiner following the Medical Research Council (MRC) as a valid tool. The scale is an ordinal scale and ranges from 0-5 whereas grade 0 to 3 has the highest reliability and with score 0 (no strength at all) to 5 (maximum strength). | From enrollment: Baseline 2 weeks (2-4 times), Intervention 12 weeks (weekly), Follow-up 6 (1x) and 12 weeks (1x) after completion of intervention |
| Pain - Numeric Rating Scale (NRS): Influence of the MDT approach on pain | For conscious patients the Numeric Pain Rating Scale (NRS) will be used. This scale measures the subjective intensity of pain. It is an 11-point scale scored from 0-10, whereas 0 = no pain and 10 = the most intense pain imaginable. It is described having a good sensitivity. | From enrollment: Baseline 2 weeks (4x), Intervention 12 weeks (12x), Follow-up 6 (1x) and 12 (1x) weeks after completion of intervention |
| Pain - Zürich Observation Pain Assessment (ZOPA): Influence of the MDT approach on pain | The Zürich Observation Pain Assessment (ZOPA) is used to external assessment of pain in people with cognitive and/ or conscious impairments in the field of neurosurgery and neurology. The instrument consists of a defined pool of items (behavioural characteristics) and is divided into four categories with a total of 13 subcategories. It provides information about the presence of pain and not about the perceived pain quality. The scale is assessed in various dimensions (e.g. facial expressions, posture, verbal expressions), with each dimension being rated on a five-point scale from 0 (no expression) to 4 (highest degree of pain). | From enrollment: Baseline 2 weeks (4x), Intervention 12 weeks (12x), Follow-up 6 (1x) and 12 (1x) weeks after completion of intervention |
| Pain - Behavioural Pain Assessment Tool: Influence of the MDT approach on pain | The behavioural pain assessment tool for patients in minimal conscious state will be used for the included patients at the Royal Hospital for Neuro-disability. It is a structured framework for recording and monitoring behaviours that may denote experience of pain in patients with prolonged disorders of consciousness. 7 items will be observed by a health-professional and then scored from 0 to 2. Whereas 0 means normal behaviour and 2 means a strong sign which can indicate stronger pain. | From enrollment: Baseline 2 weeks (4x), Intervention 12 weeks (12x), Follow-up 6 (1x) and 12 (1x) weeks after completion of intervention |
