Walking function, pain, and fatigue in adults with cerebral palsy: a 7-year follow-up study.

Aim  To compare walking function, pain, and fatigue in adults with cerebral palsy (CP) 7 years after an initial survey.

An observation instrument for assessment of work technique in patient transfer tasks.

The aim of the study was to construct an observation instrument for description and assessment of nursing personnels work technique in patient transfer tasks with regard to musculoskeletal health and safety, and to evaluate the validity and reliability of the instrument. The instrument consists of 24 items arranged in three phases of a transfer: the preparation phase, the starting position and the actual performance. Observations are made from video recordings. A detailed description of the individuals work technique, including actions taken to prepare the transfer, the interaction with the patient and any assistant co-worker, and the motor performance of the nurse, is provided. An attempt was made to quantify the assessments, by calculating an overall score of the work technique with regard to the level of musculoskeletal hazard and safety. The validity and reliability of the instrument were evaluated on 35 video-recorded patient transfers from hospital wards. The validity and reliability were mostly satisfactory, both when evaluating the agreements between the observations of each item (i.e. kappa values > 0.40), and when evaluating the agreements between the overall scores (i.e. intraclass correlation coefficients 0.71-0.90). Further improvements to enhance the agreements are suggested.

Balance in Relation to Walking Deterioration in Adults With Spastic Bilateral Cerebral Palsy

Background Balance function is central in walking, and impaired balance function may be related to walking deterioration in adults with spastic bilateral cerebral palsy (CP). Objectives The purposes of this study were: (1) to compare balance confidence, fear of falling, and balance ability in adults with spastic bilateral CP, with and without self-reported walking deterioration; (2) to characterize balance confidence, fear of falling, and balance ability across all participants; and (3) to examine the relationship between balance confidence and balance ability across all participants. Design A case-control design was used. Methods Sixteen adults from a 7-year follow-up study who had spastic bilateral CP and were under 40 years of age in the 2006 survey participated. Eight participants reported walking deterioration (cases), and 8 participants did not report walking deterioration (controls). Outcome variables were: the Activities-specific Balance Confidence (ABC) Scale, the Falls Efficacy Scale–International (FES-I), and the Balance Evaluation Systems Test (BESTest). Results No differences in any of the outcome variables were found between the cases and the controls. Across all participants, the ABC Scale and FES-I scores were 62% and 24 points, respectively. Reduced ABC Scale scores and increased FES-I scores were found when using escalators, walking in crowds, and walking on slippery surfaces. The BESTest subscale scores were 60% to 79% of the maximum score, but only 31% and 42% of the maximum score in postural responses and anticipatory adjustments, respectively. Balance confidence correlated positively with postural responses, sensory orientation, stability in gait, and BESTest total score. Limitations The lack of reliability and validity tests for the outcome variables in this study population and the small number of participants were limitations of the study. Conclusions Self-reported walking deterioration in this group could not be explained by differences in balance confidence, fear of falling, or balance ability. Across all participants, most balance problems seemed related to reduced postural responses and anticipatory adjustments.

Walking deterioration and gait analysis in adults with spastic bilateral cerebral palsy

Walking deterioration occurs frequently in adults with spastic bilateral cerebral palsy (CP), but their gait characteristics are largely unknown. The study aims were (1) to compare selected gait analysis variables between those reporting and those not reporting walking deterioration, and (2) to characterise the overall gait deviations and classify the gait patterns. Participants (N=16) were recruited from a follow-up study, had spastic bilateral CP, <40 years in 2006, GMFCS levels I-III, and could walk at least 10 m without support. Eight reported walking deterioration (cases) and eight did not (controls). A theoretical framework linking work of walking, fatigue and deterioration in walking was developed. It was hypothesised that higher energy requirements during gait and larger gait deviations would be associated with deterioration in walking. Three-dimensional gait analysis was used to obtain centre of mass work, mechanical joint work, lower limb kinematics, movement analysis profile (MAP), and gait profile scores (GPS). There were no differences between the cases and controls in centre of mass work, joint work, or in the GPS. The largest MAP deviations were seen in sagittal pelvis, hip, and knee angles and foot progression. Crouch and asymmetric gait were common patterns. Walking deterioration could not be explained by these work and kinematic variables. An individuals perception of deterioration in walking is subjective, and may be experienced and interpreted differently across people. Larger, longitudinal studies on the natural history of walking in spastic CP are needed. Qualitative studies on the subjective experiences of walking deterioration are also warranted.

Physical and mental components of health-related quality of life and musculoskeletal pain sites over seven years in adults with spastic cerebral palsy.

OBJECTIVE To analyse the number of musculoskeletal pain sites in adults with spastic cerebral palsy, to correlate these with physical and mental components of health-related quality of life, and to describe changes in pain site prevalence over 7 years and the factors improving or worsening the pain. DESIGN Seven-year follow-up of a national survey of adults with spastic cerebral palsy (CP). SUBJECTS/PATIENTS A total of 149 persons: 46% spastic bilateral CP, 54% unilateral CP, 51% females, mean age 40 years. METHODS Pain sites were recorded and physical and mental component summaries computed using Short Form 36. RESULTS The median number of pain sites was 3. The mental components showed little, if any correlation (r= -0.08), but the physical components correlated negatively with the number of pain sites (r= -0.36). Back, neck and foot/ankle pain were most common, with an increased prevalence of neck pain. A higher prevalence of hip and foot/ankle pain was found in spastic bilateral CP, and for all pain sites in females. Exertion and physiotherapy were the most important factors for increased and reduced pain, respectively. CONCLUSION In contrast to the general population, there was hardly any correlation between the number of pain sites and psychological health. Improved pain management, evidence-based physiotherapy and rehabilitation programmes with a life-span perspective are recommended.

Intramuscular and periosteal acupuncture for anxiety and sleep quality in patients with chronic musculoskeletal pain – an evaluator blind, controlled study

Objectives Periosteal acupuncture seems clinically to have a stronger effect on pain than standard intramuscular acupuncture. The aim of the present study was to compare their relative effectiveness on promoting psychological functioning and quality of sleep. Methods Consecutive patients (n=144) referred to a physiotherapist for treatment of chronic nociceptive pain in the neck or low back for more than three months, aged 18–70, were alternately allocated to an intramuscular acupuncture group (n=59), to a periosteal acupuncture group (n=55), and, for the latter part of the study, to an information control group (n=30). Eight treatments were administered during a five week period with two optional treatments after one month. All patients were encouraged to stay active. Psychological functioning was estimated with the Hospital Anxiety and Depression Scale (HAD) and quality of sleep with a visual analogue scale. All estimations were performed prior to treatment, one week after the end of treatment, and one, three and six months after end of treatment. Non-parametric statistics were used. Results There were no significant differences between the acupuncture groups, nor between the acupuncture and control groups during the treatment period. One month after treatment, the level of anxiety was lower in both acupuncture groups compared with the control group. The proportions of non-cases (HAD score 0–7) increased in the intramuscular acupuncture group from 39 to 47 (not significant), in the periosteal acupuncture group from 37 to 49 (P<0.001), and in the control group from 15 to 16. Conclusion No differences between periosteal and intramuscular acupuncture were found. One month after treatment both acupuncture interventions reduced anxiety in patients suffering from chronic nociceptive musculoskeletal pain in the neck or low back when compared with a control intervention.

Intramuscular and periosteal acupuncture in patients suffering from chronic musculoskeletal pain – a controlled trial

Background Periosteal acupuncture has shown promising results in clinical practice. The aim was to compare three patient groups: one with intramuscular acupuncture, one with periosteal acupuncture, and a third information control group, with respect to clinically relevant pain relief, physical functioning and intake of analgesics in patients with chronic musculoskeletal pain in the neck or low back or both. We reported the psychological changes in these patients in a previous issue of this journal. Methods 144 consecutive patients with nociceptive pain for >3 months, aged 18–70 years were alternately allocated to: intramuscular acupuncture (n=59); periosteal acupuncture (n=55); or control group with information only (n=30). All patients were encouraged to stay active. Acupuncture was administered with eight treatments during five weeks, and two optional additional treatments after one month. Pain was estimated with a daily VAS in a pain diary and with an average weekly pain score. Clinically relevant pain relief was defined as at least a 30% decrease from the initial value. Physical functioning was evaluated with Disability Rating Index. All estimations were performed prior to treatment, one week after, and one, three and six months after treatment. Results There were no differences between the effects of the two acupuncture methods. There were differences between each of the two acupuncture groups compared with the control group on all test occasions up to one month after treatment with respect to the pain diary and one week after treatment with respect to pain last week (P<0.05). Pain relief as measured by a pain diary was obtained in 29 patients in the intramuscular acupuncture group, 25 in the periosteal acupuncture group, and 5 patients in the control group. Six months after treatment, 46% of the intramuscular acupuncture patients and 45% of the periosteal acupuncture patients had obtained pain relief in terms of the pain diary. The corresponding figure for pain last week was 29% in each group. Conclusion Periosteal pecking was no more effective than standard intramuscular acupuncture, but both were more effective than information only.

A receptor tyrosine kinase ROR1 inhibitor (KAN0439834) induced significant apoptosis of pancreatic cells which was enhanced by erlotinib and ibrutinib

There is a great unmet medical need in pancreatic carcinoma (PC) for novel drugs with other mechanisms of action than existing. PC cells express the onco-fetal RTK ROR1, absent on most normal post-partem cells. ROR1 is involved in proliferation, survival, EMT and metastasis of tumor cells in various malignancies. A small molecule inhibitor (KAN0439834) (530 Da) targeting the TK domain of ROR1 was developed and the activity in ROR1 expressing human PC cell lines (n = 8) evaluated. The effects were compared to a murine mAb against the external part of ROR1, gemcitabine, erlotinib and ibrutinib. KAN0439834 induced significant apoptosis of the tumor cells. EC50 values for KAN0439834 varied between 250–650 nM depending on the cell line. The corresponding values for erlotinib and ibrutinib were 10–40 folds higher. KAN0439834 was much more effective in inducing tumor cell death than the ROR1 mAb although both inhibited ROR1 phosphorylation and downstream non-canonical Wnt pathway molecules. Combination of KAN0439834 with erlotinib or ibrutinib had significant additive effects on tumor cell death. A first-in-class small molecule ROR1 inhibitor (KAN0439834) showed promising in vitro activity against a number of human PC cell lines. Interesting is the additive effects of erlotinib and ibrutinib which warrants further studies as both these agents are in clinical trials for pancreatic carcinoma.
