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.
Objective: To explore driving performance and driving safety in patients with cervical dystonia (CD) on a simulated lane tracking, intersections and highway ride and to compare it to healthy controls. Design: This study was performed as an explorative between groups comparison. Participants: Ten CD patients with idiopathic CD, 30 years or older, stable on botulinum toxin treatment for over a year, holding a valid driver's license and being an active driver were compared with 10 healthy controls, matched for age and gender. Main outcome measures: Driving performance and safety, measured by various outcomes from the simulator, such as the standard deviation of the lateral position on the road, rule violations, percentage of line crossings, gap distance, and number of collisions. Fatigue and driving effort were measured with the Borg CR-10 scale and self-perceived fitness to drive was assessed with Fitness to Drive Screening. Results: Except for a higher percentage of line crossings on the right side of the road by controls (median percentage 2.30, range 0.00-37.00 vs. 0.00, range 0.00-9.20, p = 0.043), no differences were found in driving performance and driving safety during the simulator rides. Fatigue levels were significantly higher in CD patients just before (p = 0.005) and after (p = 0.033) the lane tracking ride (patients median fatigue levels before 1.5 (range 0.00-6.00) and after 1.5 (range 0.00-7.00) vs. controls median fatigue levels before and after 0.00 (no range). No significant differences were found on self-perceived fitness to drive. Conclusion: In patients with CD there were no indications that driving performance or driving safety were significant different from healthy controls in a simulator. Patients reported higher levels of fatigue both before and after driving compared to controls in accordance with the non-motor symptoms known in CD.
Purpose: To systematically review the literature on effectiveness of remote physiotherapeutic e-Health interventions on pain in patients with musculoskeletal disorders. Materials and methods: Using online data sources PubMed, Embase, and Cochrane in adults with musculoskeletal disorders with a pain-related complaint. Remote physiotherapeutic e-Health interventions were analysed. Control interventions were not specified. Outcomes on effect of remote e-Health interventions in terms of pain intensity. Results: From 11,811 studies identified, 27 studies were included. There is limited evidence for the effectiveness for remote e-Health for patients with back pain based on five articles. Twelve articles studied chronic pain and the effectiveness was dependent on the control group and involvement of healthcare providers. In patients with osteoarthritis (five articles), total knee surgery (two articles), and knee pain (three articles) no significant effects were found for remote e-Health compared to control groups. Conclusions: There is limited evidence for the effectiveness of remote physiotherapeutic e-Health interventions to decrease pain intensity in patients with back pain. There is some evidence for effectiveness of remote e-Health in patients with chronic pain. For patients with osteoarthritis, after total knee surgery and knee pain, there appears to be no effect of e-Health when solely looking at reduction of pain. Implications for rehabilitation This review shows that e-Health can be an effective way of reducing pain in some populations. Remote physiotherapeutic e-Health interventions may decrease pain intensity in patients with back pain. Autonomous e-Health is more effective than no treatment in patients with chronic pain. There is no effect of e-Health in reduction of pain for patients with osteoarthritis, after total knee surgery and knee pain.Implications for rehabilitation* This review shows that e-Health can be an effective way of reducing pain in some populations.* Remote physiotherapeutic e-Health interventions may decrease pain intensity in patients with back pain.* Autonomous e-Health is more effective than no treatment in patients with chronic pain.* There is no effect of e-Health in reduction of pain for patients with osteoarthritis, after total knee surgery and knee pain.
