Cervical dystonia is the most frequent form of focal dystonia. Symptoms often result in pain and functional disability. Local injections of botulinum neurotoxin are currently the treatment of choice for cervical dystonia. Although this treatment has proven effective and is widely applied worldwide, many issues still remain open in the clinical practice. We performed a systematic review of the literature on botulinum toxin treatment for cervical dystonia based on a question-oriented approach, with the aim to provide practical recommendations for the treating clinicians. Key-questions from the clinical practice were explored. Results suggest that while the beneficial effect of botulinum toxin treatment on different aspects of cervical dystonia is well established, robust evidence is still missing concerning some practical aspects, such as doseequivalence between different formulations, optimal treatment intervals, treatment approaches, and the use of supportive techniques including electromyography (EMG) or ultrasounds. Established strategies to prevent or manage common side effects (including excessive muscle weakness, pain at injection site, dysphagia) and potential contraindications to this treatment (pregnancy and lactation, use of anticoagulants, neurological comorbidities) should also be further explored.
Cervical dystonia (CD) is a neurological movement disorder characterized by involuntary muscle contractions causing abnormal postures and/or twisting movements of the head and neck.Patients may also experience non-motor symptoms including pain, anxiety and depression. The main treatment option is botulinum toxin (BoNT) injections in affected muscles to improve head postures and reduce pain. In addition to BoNT treatment, patients are often referred for physical therapy (PT), but there is little evidence regarding the long-term effectiveness.Despite remarkable improvements during the last decades, there are still many unmet needs that remain open in the treatment of cervical dystonia (CD). The first goal of this thesis was to assess clinical issues in BoNT treatment that need further improvement and to define clinical recommendations for clinicians. The second goal was to explore which determinants play an important role in disability of CD patients and the third goal was to develop a specialized PT program and to evaluate its effects on disability.Results showed that BoNT treatment can be further improved despite all the evidence for its effectiveness. Further research is needed towards optimal treatment intervals, dose equivalence between different BoNT formulations, the use of supportive techniques like electromyography or ultrasound and managing side effects. Secondly, we found that psychological factors are important determinants of disability. Finally, we found that PT is a valuable addition to BoNT treatment to improve disability and pain. Based on these findings, a multidisciplinary treatment approach to further improve the treatment and quality of life for CD patients is recommended.
BackgroundSeveral conditions and diseases can result in speech problems that can have a negative impact on everyday functioning, referred to as communicative participation. Subjective problems with acquired speech problems are often assessed with the speech handicap index (SHI). To assess generic participation problems, the Utrecht Scale for Evaluation of Rehabilitation–Participation (USER-P) questionnaire is frequently used. The English questionnaire Communicative Participation Item Bank—short form (CPIB short form) is a 10-item valid, reliable instrument that assesses communicative participation. In the absence of a Dutch equivalent, translation and validation of the CPIB short form was required.AimsTo translate the CPIB short form into Dutch, and to determine its psychometric properties for the group of adults with speech problems resulting from a neurological aetiology or head and neck cancer.Methods & ProceduresTranslation of the CPIB short form was performed following the instructions of the European Organisation for Research and Treatment for Cancer (EORTC). In a cross-sectional multi-centre study, participants completed the Dutch CPIB short form together with the SHI and USER-P, and the CPIB a second time after 2 weeks. We assessed internal consistency and test–retest reliability of the CPIB. Construct validity was assessed based on correlations with SHI, USER-P and speech assessments.Outcomes & ResultsIn the validation study, 122 participants were included: 51 with dysarthria due to different neurological disorders, 48 with speech problems due to head and neck cancer treatment and 23 healthy controls. Internal consistency of the items was high (Cronbach's alpha = 0.962), the intraclass correlation coefficient (ICC) for test–retest reliability was high 0.908 (95% CI = 0.870–0.935). Construct validity was supported by a strong correlation between the Dutch CPIB short form and the SHI total score (SHI total rs = 0.887) and a moderate correlation between the Dutch CPIB-10 and the USER-P subscales (USER-P Frequency rs = 0.365; USER-P restrictions and USER-P satisfaction rs = 0.546). A moderate correlation was found between the Dutch CPIB-10 and the speech performance assessments (degree of distortedness r = −0.0557; p ≤ 0.001; degree of intelligibility r = 0.0562).Conclusions & ImplicationsThe Dutch CPIB short form provides a valid and reliable tool for clinical practice and research purposes. It allows clinicians to start using this PROM in clinical and research practice to systematically investigate the impact of the speech problems on communicative participation in a Dutch-speaking population.What this paper addsWhat is already known on the subjectCommunicative participation allows people to take part in life situations, but can be affected by acquired speech problems. The CPIB is a patient-reported outcome measure for the assessment of this concept. For the English language the 46-item bank and a 10-item short form is available.What this paper adds to existing knowledgeThis paper describes the process of translation of the CPIB short form into Dutch, and confirms its reproducibility and validity.What are the potential or actual clinical implications of this work?With this validated Dutch version of the CPIB short form available, professionals can implement this tool in clinical and research practice to systematically evaluate communicative participation.
Low back pain is the leading cause of disability worldwide and a significant contributor to work incapacity. Although effective therapeutic options are scarce, exercises supervised by a physiotherapist have shown to be effective. However, the effects found in research studies tend to be small, likely due to the heterogeneous nature of patients' complaints and movement limitations. Personalized treatment is necessary as a 'one-size-fits-all' approach is not sufficient. High-tech solutions consisting of motions sensors supported by artificial intelligence will facilitate physiotherapists to achieve this goal. To date, physiotherapists use questionnaires and physical examinations, which provide subjective results and therefore limited support for treatment decisions. Objective measurement data obtained by motion sensors can help to determine abnormal movement patterns. This information may be crucial in evaluating the prognosis and designing the physiotherapy treatment plan. The proposed study is a small cohort study (n=30) that involves low back pain patients visiting a physiotherapist and performing simple movement tasks such as walking and repeated forward bending. The movements will be recorded using sensors that estimate orientation from accelerations, angular velocities and magnetometer data. Participants complete questionnaires about their pain and functioning before and after treatment. Artificial analysis techniques will be used to link the sensor and questionnaire data to identify clinically relevant subgroups based on movement patterns, and to determine if there are differences in prognosis between these subgroups that serve as a starting point of personalized treatments. This pilot study aims to investigate the potential benefits of using motion sensors to personalize the treatment of low back pain. It serves as a foundation for future research into the use of motion sensors in the treatment of low back pain and other musculoskeletal or neurological movement disorders.
De samenwerking tussen de onderzoeksgroep FRIA van de Vrije Universiteit Brussel, afdeling oudergeneeskunde van het UMCG Groningen en de onderzoeksgroep (lectoraat) Healthy Ageing, Allied health Care and Nursing van de Hanzehogeschool Groningen is gericht op onderzoek naar bewegingsstoornissen bij veroudering. In het bijzonder wordt gekeken naar paratonic, een bewegingsstoornis bij dementie.The International Joint Research group ‘Move in Age’ concluded in a systematic review that paratonia still is a barely understood and devastating phenomenon in dementia and revealed the urgency of gaining more insight in the pathophysiology. Paratonia, a distinctive change in muscle tone, starts in early stages of dementia and develops further with progress of the disease. Resulting in severe discomfort for patients, but also affecting caregivers since daily care becomes increasingly difficult. It is hypothesized that changes in motor control due to dementia influences peripheral neurological control and biomechanical muscle structures (by crosslinking and inflammation caused by advanced glycation end-products (AGEs).This IJRG started in 2018 and aims to develop a long-term comprehensive research program on movement-related impairments at higher age. The three partners have a strong track record on research in the area of movement-related impairments in older persons; however, each focusing on a specific aspect. In fact, the Frailty in Ageing research group (FRIA) of the Vrije Universiteit Brussel (VUB) is running focused research program on the triad sarcopenia-dynapenia-inflammation with mainly a bio-gerontological and bio-psycho-medical approach; the department of General Practice and Elderly Care Medicine of the University Medical Center Groningen (UMCG) has anongoing research line on the medical aspects of mobility impairments in frail elderly persons and in elderly dementia patients; and finally Research Group Healthy Ageing, Allied Health Care and Nursing of the Hanze University of Applied Sciences Groningen (HUAS) developed a research program on physical, psycho-cognitive and social dimensions of frailty including the functional impact of mobility impairments. In the first 3-5 years, the focus will be on the movement-related impairments that occur in patients with dementia and in specific on paranoia. The programme will be extended towards movement-related impairments in the context of other geriatric syndromes.
