Tidskriftsartikel (refereegranskat)abstract
- This article focuses on patients’ accounts of chronic pain and the manner in which they communicate their experiences. The data have been generated through interviews with chronic pain patients undergoing treatment for their problems. The results show that patients develop a set of discursive markers by means of which they are able to make distinctions between different kinds of pain. These distinctions are made with respect to pain qualities and pain localizations in the body. Further, a majority of the patients report that one pain generally transforms into another. This subjectively perceived patterning we refer to as pain transformations and these, in turn, contain different pain phases. Most patients report pains as dynamic and tients report pains as dynamic and stable and consistent sensation. The results also show that some patients identify certain pain phases as precursors of more severe phases, and that they use this knowledge as a means for taking preventive actions. Since experiencing pain often involves a discursive element gaining linguistic control over one’s pain provides the person with an important resource for dealing with pain

Generalized pain is associated with more negative consequences than local or regional pain : A study of chronic whiplash-associated disorders
- 2007
-
Ingår i: Journal of Rehabilitation Medicine. - : Medical Journals Sweden AB. - 1650-1977 .- 1651-2081 .- 0001-5555. ; 39:3, s. 260-268

Tidskriftsartikel (refereegranskat)abstract
- Objective: The main aims of this study were: (i) to determine, for chronic whiplash-associated disorders, whether widespread pain has more severe consequences for other symptoms and different aspects of perceived health than does local/regional pain; (ii) to investigate whether pain, depression, and symptoms not directly related to pain are intercorrelated and to what extent these symptoms correlate with catastrophizing according to the Coping Strategy Questionnaire. Design: Descriptive cross-sectional study. Patients: A total of 275 consecutive chronic pain patients with whiplash-associated disorders who were referred to a university hospital. Methods: Background history, Beck Depression Inventory, Coping Strategy Questionnaire, Life Satisfaction Checklist, the SF-36 Health Survey and EuroQol were used to collect data. Results: Spreading of pain was associated with negative consequences with respect to pain intensity and prevalence of other symptoms, life satisfaction/quality and general health. The subjects differ with respect to the presence of symptoms not directly related to pain. A minor part of the variation in Back Depression Inventory was explained by direct aspects of pain, indicating that, to some extent, generalization of pain is related to catastrophizing thoughts. Conclusion: Widespread pain was associated with negative consequences with respect to pain intensity, prevalence of other symptoms including depressive symptoms, some aspects of coping, life satisfaction and general health.

Living with chronic pain : A dynamic learning process
- 2000
-
Ingår i: Scandinavian Journal of Occupational Therapy. - : Informa UK Limited. - 1103-8128 .- 1651-2014. ; 7:3, s. 114-125
-
Tidskriftsartikel (refereegranskat)abstract
- This study focuses on how patients describe and manage their pain in their everyday life. The data consist of interviews with 37 patients undergoing treatment for chronic pain. The study focuses on how experiences of pain are mediated and interpreted with the help of the individual's discursive resources. It is argued that this kind of resource is important in constituting a structure of relations between a suffering person, pain and context. In the analysis of the material a four-step procedure was used, including both formal and content-related aspects. It was found that the patients describe chronic pain as a dynamic phenomenon. Patients learn about their pain by actively constituting relations among themselves, the pain and their activities. For the patients, chronic pain is a structured phenomenon. Patients often describe how pain is initiated, worsens and is alleviated. Patients thereby learn to distinguish different figures in their pain, which they are able to relate to in their management of pain. This suggests that a life in pain could be seen as an apprenticeship process. The heart of the matter in this process is learning to become sensitive to and flexible towards variations in the pain and potential pain triggers in the environment. This knowledge is important, as mastering pain is a balancing act between inner resources and environmental circumstances.

Modelling human musculoskeletal functional movements using ultrasound imaging
- 2010
-
Ingår i: BMC Medical Imaging. - : Springer Science and Business Media LLC. - 1471-2342. ; 10, s. 9-
-
Tidskriftsartikel (refereegranskat)abstract
- Background: A widespread and fundamental assumption in the health sciences is that muscle functions are related to a wide variety of conditions, for example pain, ischemic and neurological disorder, exercise and injury. It is therefore highly desirable to study musculoskeletal contributions in clinical applications such as the treatment of muscle injuries, post-surgery evaluations, monitoring of progressive degeneration in neuromuscular disorders, and so on.The spatial image resolution in ultrasound systems has improved tremendously in the last few years and nowadays provides detailed information about tissue characteristics. It is now possible to study skeletal muscles in real-time during activity.Methods: The ultrasound images are transformed to be congruent and are effectively compressed and stacked in order to be analysed with multivariate techniques. The method is applied to a relevant clinical orthopaedic research field, namely to describe the dynamics in the Achilles tendon and the calf during real-time movements.Results: This study introduces a novel method to medical applications that can be used to examine ultrasound image sequences and to detect, visualise and quantify skeletal muscle dynamics and functions.Conclusions: This new objective method is a powerful tool to use when visualising tissue activity and dynamics of musculoskeletal ultrasound registrations.

Smärtans mosaik : kommunikation och lärande om långvarig smärta
- 2001
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis focuses on how people, living with long-term pain, exploreand communicate their pain, by way of speech as a means for producingrelations between themselves, the. pain and everyday activities. The datamaterial consists of focused research interviews with patients undergoingtreatment for their pain at a pain clinic. The thesis takes as a point ofdeparture that people living with pain in various situations need tocommunicate their pain experiences which posits the person in acommunicational dilemma giving_ shape to a multi-dimensionalexperience. Different kinds of communicative resources are used in thesecommunication situations, verbal and figurative talk together withgestures. It is argued that learning about one's pain could be described as an apprenticeship process, which concerns as well the relations between the afflicted person and the her/his pain as how these relations are to be communicated. An important result is that mastering one's pain is about an on-going, situated, searching and communicative practice.

The Metaphors for pain : a study of pain metaphors as communication
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- When describing pain the spoken language one is used to is often inadequate. This article takes as departure this communicative problem. The datamaterial consists of semi-structured interviews with thirty-seven patients undergoing treatment for their chronic pain.The metaphor consists of two parts or domains: the domain to be described and the domain from which a description is borrowed. 145 metaphors were identified in the data material. The analysis concernedboth the domains, their relationship and the metaphor's communicative function. The results shows that different types of 'linguisticimages' were used to describe pain, and that the relationship between the two domains were of two kinds: experiential and semantic,respectively. Further, five communicative functions of the metaphorical talk were found: a comparative, structuring, contextulising,problematising and interactive, function respectively. It is argued that professional caregivers by metaphorical talk could acquire indirect access to fragment of patients' experiences of pain, create interactivity and compliance.

Tidskriftsartikel (refereegranskat)abstract
- Local metabolic changes are suggested to be involved in muscle pain development in humans. Nineteen women with chronic work-related trapezius myalgia (TM) and 20 healthy female controls (CON) were studied during baseline rest, 20 min repetitive low-force exercise, and 120 min recovery. Interstitial serotonin (5-HT), glutamate, lactate, pyruvate, and blood flow were determined by microdialysis in the trapezius muscle. Baseline pressure pain threshold (PPT) was lower (143+/-18 (TM) vs. 269+/-17 (CON) kPa) (mean +/- SEM), pain intensity (visual analogue scale, VAS) higher (33+/-5 vs. 2+/-1 mm), muscle 5-HT higher (22.9+/-6.7 vs. 3.8+/-1.3 nmol/l), and glutamate higher (47+/-3 vs. 36+/-4 mumol/l) in TM than in CON (all P<0.05), whereas muscle blood flow was similar in groups. Furthermore, muscle pyruvate was higher (180+/-15 vs. 135+/-12 mumol/l) and lactate higher (4.4+/-0.3 vs. 3.1+/-0.3 mmol/l) in TM than in CON (P<0.001). In response to exercise, VAS and glutamate increased in both TM and CON (all P<0.05). In TM only, lactate and pyruvate increased significantly (P<0.02), whereas blood flow increased to similar levels in both groups. During the initial 20 min recovery period, blood flow remained increased in TM (P<0.005) whereas it decreased to baseline levels in CON. In conclusion, patients with chronic work-related TM have increased levels of muscle 5-HT and glutamate that were correlated to pain intensity (r=0.55, P<0.001) and PPT (r=-0.47, P<0.001), respectively. In addition, TM was associated with increased anaerobic metabolism, whereas a normal rise in blood flow was seen with exercise. These findings indicate that peripheral nociceptive processes are active in work-related TM.

Increased levels of interstitial potassium but normal levels of muscle IL-6 and LDH in patients with trapezius myalgia

Tidskriftsartikel (refereegranskat)abstract
- The mechanisms behind the development of work-related trapezius pain are suggested to involve both peripheral and central components, but the specific contribution of alterations in muscle nociceptive and other substances is not clear. Female patients with chronic trapezius myalgia (N = 19; TM) and female controls (N = 20; CON) were studied at rest, during 20 min repetitive low-force exercise and recovery, and had their interstitial concentrations of potassium (K+), lactate dehydrogenase (LDH), interleukin-6 (IL-6) and collagen turnover determined in the trapezius muscle by the microdialysis technique. K+ levels were at all time points higher in TM than in CON (P < 0.0001). Baseline levels of LDH and IL-6 were similar in both groups. In response to exercise pain intensity, rated perceived exertion, and the concentrations of K+, LDH and IL-6 increased significantly in both groups. [K+] immediately decreased to baseline levels in CON but remained elevated during the first 20 min of recovery in TM (P < 0.01) whereafter it returned to baseline level. In all subjects taken together mean [K+] correlated negatively with pressure pain threshold of trapezius (P < 0.001), positively with mean pain intensity VAS (P < 0.001) and mean perceived exertion (P < 0.001). Rises in muscle LDH and IL-6 as well as the anabolic ratio for collagen type I was not significantly different between groups. In conclusion, patients with chronic pain in the trapezius muscle had increased levels of interstitial potassium. This finding could be causally related to myalgia or secondary to pain due to deconditioned muscle or altered muscle activity pattern.
