Dutch Dataset Vocational Rehabilitation for Chronic Musculoskeletal Pain: Baseline Patients' Characteristics and Program Eligibility.

PURPOSE: Vocational rehabilitation (VR) is an intervention to improve return to work for patients with chronic musculoskeletal pain (CMP). However, a systematic overview of characteristics of referred patients or eligible for VR is lacking, which hinders comparability across studies. Objectives were (1) to describe characteristics of patients with CMP referred to and eligible for VR and (2) to identify factors that contribute to VR eligibility. METHODS: This study used a multicenter, cross-sectional design. Data of self-reported questionnaires were obtained between 2013 and 2019 from care as usual of eight Dutch VR centers. Descriptive statistics were performed to describe sociodemographic, pain-related, and work-related characteristics. Logistic regression analysis was used to identify factors contributing to VR eligibility. RESULTS: Data sets of n = 2970 referred patients were included. The mean age was 46 years and 60% were female. Low back (43%), neck (37%), and shoulder pain (34%) were most reported. 82% Worked in paid employment. The absenteeism rate was 85%, and 44% was partially absent. After multidisciplinary screening, 62.2% were eligible for VR. Persons most likely to be eligible for VR (OR < 1.20) were those having back or neck pain, whereas least eligible (OR < 0.80) were persons having pain in hand/fingers or pain in other regions, unemployed workers, and those referred by a 'other' medical specialists. All other factors contributed little or none to the model. CONCLUSIONS: An extensive description of sociodemographic, pain-related, and work-related characteristics is presented for patients eligible for VR. Especially having back/neck pain and being an employee were associated with higher chance of eligibility for VR.

A modified Gritti-Stokes amputation technique as a solution for recurring aseptic loosening of a knee arthroplasty: A single-patient case study.

CASE DESCRIPTION: A 56-year-old man with persistent knee pain and poor physical functioning due to recurring loosening of a (revised) total knee arthroplasty, was treated with a modified Gritti-Stokes amputation. OBJECTIVES: to describe the modified Gritti-Stokes amputation technique as an ultimate therapy for failed total knee arthroplasty and to assess the functional outcome for one patient 1 year post-surgery. STUDY DESIGN: a single patient case study. TREATMENT: a modified Gritti-Stokes amputation, with removal of the overlying cartilage and subchondral surfaces of both the patella and femur after removing the total knee arthroplasty. OUTCOMES: After rehabilitation, the patient has a fully end-bearing residual limb, is able to walk without pain (with a prosthesis) and perform his daily activities. CONCLUSIONS: In cases of recurring loosening of a (revised) total knee arthroplasty, a modified Gritti-Stokes amputation can create an end-bearing residual limb without pain and with good functional outcome.

Test-retest reliability of the special interest group on amputation medicine/Dutch working group on amputations and prosthetics mobility scale, in persons wearing a prosthesis after a lower-limb amputation.

Purpose: To assess the test-retest reliability of the Special Interest Group on Amputation Medicine Mobility Scale/Dutch Working Group on Amputations and Prosthetics, better known as SIGAM/WAP mobility scale, in persons with a lower-limb amputation.Method: Longitudinal study at the outpatient departments of a rehabilitation center and a university medical center. Persons with a lower-limb amputation, wearing a prosthesis, were assessed at the end of their multidisciplinary rehabilitation treatment twice, with a 3-week interval, by the same practitioner. Test-retest reliability was quantified using the intraclass correlation coefficient for agreement.Results: Eighty persons participated (mean age ± SD, 61 ± 15 years; 61% men; 76% vascular cause of amputation; 70% able to walk >50m). Fifty-one of them rated themselves to be stable with respect to their mobility and their intraclass correlation coefficient was 0.90 (95% confidence intervals 0.84-0.94).Conclusions: The Special Interest Group on Amputation Medicine Mobility Scale/Dutch Working Group on Amputations and Prosthetics had, at the outpatient departments of a rehabilitation center and a university medical center, excellent test-retest reliability in persons wearing a prosthesis after a lower-limb amputation.Implications for rehabilitationThe Special Interest Group on Amputation Medicine/Dutch Working Group on Amputations and Prosthetics Mobility Scale was developed to classify mobility after a lower-limb amputation and wearing a prosthesis.The Dutch translation of this mobility scale has excellent test-retest reliability.

Energy Conservation Management for People With Multiple Sclerosis-Related Fatigue: Who Benefits?

OBJECTIVE: We investigated whether demographic, disease-related, or personal baseline determinants can predict a positive response to energy conservation management (ECM). METHOD: We conducted a secondary analysis of a single-blind, two-parallel-arms randomized controlled trial that included ambulatory adults with severe MS-related fatigue. Therapy responders and nonresponders were categorized by Checklist Individual Strength fatigue change scores between baseline and end of treatment. Logistic regression analyses were used to assess the determinants of response. RESULTS: Sixty-nine participants were included (ECM group, n = 34; control group, n = 35). In the ECM group, fatigue severity, perception of fatigue, illness cognitions about MS, and social support discrepancies were related to the probability of being a responder. CONCLUSION: The results suggest that people with MS-related fatigue who had a less negative perception of fatigue and who perceived fewer disease benefits and a higher discrepancy in social support had the best response to ECM treatment.

Advantages and disadvantages of interdisciplinary consultation in the prescription of assistive technologies for mobility limitations.

PURPOSE: To explore the advantages and disadvantages experienced by professionals in interdisciplinary consultation involving the user, prescriber and technician in the prescription of assistive technologies for mobility limitations. METHOD: Cross-sectional study. Prescribers (N = 39) and orthopaedic technicians (N = 50), who were regularly involved in an interdisciplinary consultation completed a questionnaire about advantages and disadvantages of the interdisciplinary consultation. RESULTS: Advantages of the interdisciplinary consultation were mentioned within all CanMEDS areas of medical practice, including better and quicker prescription of the assistive technology, shared knowledge of medical diagnosis and device possibilities, shared decision making of the device prescription and clear communication rules. Disadvantages were mentioned in the CanMEDS areas management and collaboration, including planning problems (financial) reimbursement of this type of consultation, and time efficiency. On a 10-point scale, mean (standard deviation) rates of interdisciplinary consultations were 7.9 (0.6) according to prescribers, and 7.8 (0.9) by technicians. All participants wanted to continue the interdisciplinary consultation. CONCLUSIONS: Prescribers and technicians in the field of assistive technologies for walking mobility limitations appreciate an interdisciplinary consultation. Advantages are found in all CanMEDS areas, whereas disadvantages only concern coordination. It should be encouraged to realize this kind of consultation in all situations where such technologies are prescribed. Implications for rehabilitation Interdisciplinary consultation involving the user, prescriber and technician to prescribe assistive technologies for mobility limitations has many advantages in all CanMEDS areas of medical practice, and few disadvantages, related to management and collaboration only. The disadvantages of interdisciplinary consultation, such as (financial) reimbursement by health insurance companies, have to be taken into account. Professionals in the field of ankle-foot-orthoses and orthopaedic shoes (medical specialist as prescriber and orthopaedic technician) who are involved in interdisciplinary consultation appreciate it and want to continue.

Prevalence of comorbidity and its association with demographic and clinical characteristics in persons wearing a prosthesis after a lower-limb amputation.

OBJECTIVE: To describe the prevalence of comorbidity and its relationship with demographic and clinical characteristics in persons wearing a prosthesis after lower-limb amputation. DESIGN: Cross-sectional study. SUBJECTS/PATIENTS: Persons wearing a prosthesis after lower-limb amputation (n = 171; mean age 65 years (standard deviation 12); 72% men) at the end of outpatient rehabilitation treatment. METHODS: Comorbidity was assessed with the Func-tional Comorbidity Index: a list of 18 items addressing the presence of specific comorbid conditions impacting on functional status. Comorbidities in medical records were assessed independently by 2 assessors. Associations with demographic and clinical characteristics were analysed using linear or logistic regression. RESULTS: The median (interquartile range) number of comorbidities was 3 (2; 4). Three or more comorbidities were present in 103 of 171 (60%) participants. Diabetes was present in 71 (41%), cardiac disease in 60 (35%), and lumbago/degenerative disc disease in 39 (23%) participants. The prevalence of comorbidities was higher in women and those with vascular cause of amputation. CONCLUSION: There is a high prevalence of comorbidity at the end of outpatient rehabilitation treatment in persons wearing a prosthesis after a lower-limb amputation, especially in women and those with vascular cause of amputation.

Effectiveness of energy conservation management on fatigue and participation in multiple sclerosis: A randomized controlled trial.

BACKGROUND: Fatigue is a frequently reported and disabling symptom in multiple sclerosis (MS). OBJECTIVE: To investigate the effectiveness of an individual energy conservation management (ECM) intervention on fatigue and participation in persons with primary MS-related fatigue. METHODS: A total of 86 severely fatigued and ambulatory adults with a definite diagnosis of MS were randomized in a single-blind, two-parallel-arm randomized clinical trial to the ECM group or the information-only control group in outpatient rehabilitation departments. Blinded assessments were carried out at baseline and at 8, 16, 26 and 52 weeks after randomization. Primary outcomes were fatigue (fatigue subscale of Checklist Individual Strength - CIS20r) and participation (Impact on Participation and Autonomy scale - IPA). RESULTS: Modified intention-to-treat analysis was based on 76 randomized patients (ECM, n = 36; MS nurse, n=40). No significant ECM effects were found for fatigue (overall difference CIS20r between the groups = -0.81; 95% confidence interval (CI), -3.71 to 2.11) or for four out of five IPA domains. An overall unfavourable effect was found in the ECM group for the IPA domain social relations (difference between the groups = 0.19; 95% CI, 0.03 to 0.35). CONCLUSION: The individual ECM format used in this study did not reduce MS-related fatigue and restrictions in participation more than an information-only control condition.

Development of a cosmetic knee disarticulation prosthesis: A single-patient case study.

BACKGROUND AND AIM: If a person does not become ambulant after an amputation, a knee disarticulation (KD) shouldbe considered and the person may then benefit from a cosmetic KD prosthesis. The features of a cosmetic KD prosthesis are, however, seldom described. The aim of this clinical note is to describe the development of a cosmeticKD prosthesis. TECHNIQUE: A non-ambulant person with bilateral KD formulated, together with her physiatrist, the criteria for a cosmetic KD prosthesis. On the basis of these, a lightweight, natural-looking, well-fitting, easy-to-put-on and take-off KD prosthesis, with no thigh lengthening during sitting, was made. This prosthesis was fixed on a wheelchair and does not impede transfer. DISCUSSION: A newly constructed cosmetic prosthesis for non-ambulant persons with a KD is described in detail. We hope that this will encourage physiatrists and prosthetists to offer non-ambulant persons with a KD a cosmetic prosthesis. CLINICAL RELEVANCE: A cosmetic leg prosthesis with good cosmetic properties, good sitting comfort, and no restrictions in making transfers is described in detail for non-ambulant persons with a knee disarticulation.

Perceived independence and limitations in rising and sitting down after rehabilitation for a lower-limb amputation.

OBJECTIVE: To study perceived independence in rising and perceived limitations in rising and sitting down in persons after a lower-limb amputation and the relationship of these perceptions with personal and clinical characteristics. DESIGN: Cross-sectional study. SUBJECTS/PATIENTS: Persons with a lower-limb amputation wearing a prosthesis (n = 172). METHODS: Perceived independence in rising was assessed with the Locomotor Capabilities Index. Limitations in rising and sitting down were assessed with the Questionnaire Rising and Sitting down. Multivariate logistic and linear regression analyses, respectively, were used to investigate the associations between independence and limitations in rising and sitting down, and personal and clinical characteristics. RESULTS: Of the participants, 91% and 47% perceived independence in rising from a chair and rising from the floor, respectively. Older participants and women perceived less independence in rising. Participants perceived marked limitations in rising and sitting down, with those rehabilitated in a nursing home perceiving more limitations. CONCLUSION: After a lower-limb amputation, most persons wearing a prosthesis are able to rise independently from a chair, but many perceive decreased independence in other forms of rising, especially older participants and women. Participants, especially those rehabilitated in a nursing home, perceive considerable limitations in rising and sitting down. However, in those patients rehabilitated in a nursing home these limitations may be due to indication bias.

Cosmetic effect of knee joint in a knee disarticulation prosthesis.

Despite numerous advantages, knee disarticulations (KDs) are rarely performed because of the anticipated KD prosthesis fitting problems that include the positioning of the knee joint distally from the KD socket. This results in lengthening of the thigh and subsequent shortening of the shank. The objective of this study was to assess the cosmetic effect of the knee joint in a KD prosthesis by determining the extent of the lengthening of the thigh and the shortening of the shank. This lengthening and shortening were measured through an experimental setup using laser techniques. These measurements were made of 18 knee joints used in KD prostheses. Lengthening of the thigh varied between 23 and 92 mm, and shortening of the shank varied between 3 and 50 mm. The polycentric knees Medi KH6 and Medi KHF1 showed the least lengthening of the thigh, and the polycentric knees Teh Lin Prosthetic & Orthotic Co. Ltd Graph-Lite and Medi KP5 showed the least shortening of the shank.

Climbing stairs after outpatient rehabilitation for a lower-limb amputation.

OBJECTIVE: To study the necessity and ability to climb stairs in persons after a lower-limb amputation (LLA) and the relation of this ability with personal and clinical variables. DESIGN: Cross-sectional study. SETTING: Outpatient department of a rehabilitation center. PARTICIPANTS: Persons with an LLA (N=155; mean age ± SD, 64.1 ± 11.2y; 73% men). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The necessity to climb stairs was assessed with the Prosthetic Profile of the Amputee. Several indicators of the ability to climb stairs were assessed including: (1) independence in climbing stairs with a handrail and (2) without a handrail, according to the Locomotor Capabilities Index; (3) numbers of floors actually climbed, according to a rating scale; and (4) limitations in climbing stairs, according to the Climbing Stairs Questionnaire (range, 0-100, with higher scores indicating less limitations). Multivariate logistic regression analysis was used to investigate the associations between the ability to climb stairs and personal and clinical variables. RESULTS: Of the participants, 47% had to climb stairs. The ability to climb stairs was: (1) 62% independently climbed stairs with a handrail and (2) 21% without a handrail; (3) 32% didn't climb any stairs, 34% climbed half a floor or 1 floor, and 34% climbed ≥ 2 floors; (4) the median sum score (interquartile range) of the Climbing Stairs Questionnaire was 38 (19-63), indicating marked limitations. Older participants and women were less able to climb stairs with and without a handrail. CONCLUSIONS: A considerable number of persons with an LLA have to climb stairs in their home environment. Many of them, especially older participants and women, are particularly hampered in their ability to climb stairs.

Construct validity and test-retest reliability of the walking questionnaire in people with a lower limb amputation.

OBJECTIVE: To investigate the construct validity and test-retest reliability of the Walking Questionnaire, a patient-reported measure of activity limitations in walking in people with a lower limb amputation. DESIGN: Cross-sectional study. SETTING: Outpatient department of a rehabilitation center. PARTICIPANTS: People with a lower limb amputation (N=172; mean age ± SD, 65±12y; 71% men; 82% vascular cause) participated in the study, 33 of whom also participated in the reliability study. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Construct validity was investigated by testing 11 hypotheses: limitations in walking according to the Walking Questionnaire will be greater in people with a lower limb amputation who (1) are older, (2) have a bilateral amputation, (3) have a higher level of amputation, (4) underwent their rehabilitation treatment in a nursing home, (5) walk less (in terms of time), and (6) walk shorter distances. Furthermore, limitations in walking will be positively related to activity limitations according to the (7) Locomotor Capabilities Index, (8) "distance walked" question on the Prosthetic Profile of the Amputee Questionnaire, (9) Questionnaire Rising and Sitting Down, (10) Climbing Stairs Questionnaire, and (11) Special Interest Group on Amputation Medicine/Dutch Working Group on Amputations and Prosthetics mobility scale. Construct validity was quantified by using the Mann-Whitney U test and Spearman correlation coefficient. Test-retest reliability was assessed with a 3-week interval and quantified using the intraclass correlation coefficient. RESULTS: Construct validity (10 of 11 hypotheses not rejected) and test-retest reliability were good (intraclass correlation coefficient =.73; 95% confidence interval, .43-.88). CONCLUSIONS: The Walking Questionnaire has good construct validity and test-retest reliability in people with a lower limb amputation.

Construct validity and test-retest reliability of the questionnaire rising and sitting down in lower-limb amputees.

OBJECTIVE: To investigate the construct validity and test-retest reliability of the Questionnaire Rising and Sitting Down (QR&S), a patient-reported measure of activity limitations in rising and sitting down, in lower-limb amputees. DESIGN: Cross-sectional study. SETTING: Outpatient department of a rehabilitation center. PARTICIPANTS: Lower-limb amputees (N=171; mean age ± SD, 65±12y; 71% men; 83% vascular cause) participated in the study, 33 of whom also participated in the reliability study. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Construct validity was investigated by testing 8 hypotheses: limitations in rising and sitting down according to the QR&S would be: (1) greater in lower-limb amputees who are older, (2) independent of level of amputation, (3) greater in lower-limb amputees with a bilateral amputation, and (4) greater in lower-limb amputees who had rehabilitation treatment in a nursing home. Furthermore, limitations in rising and sitting down will be positively related to activity limitations according to (5) the Locomotor Capabilities Index (LCI), (6) the questions about rising and sitting down in the LCI, (7) the Climbing Stairs Questionnaire, and (8) the Walking Questionnaire. Construct validity was quantified with an independent t test and Pearson correlation coefficient. Test-retest reliability was assessed with a 3-week interval and quantified with the intraclass correlation coefficient (ICC), standard error of measurement, and smallest detectable difference (SDD). RESULTS: Construct validity (7 of 8 null hypotheses not rejected) and test-retest reliability were good (ICC=.84; 95% confidence interval, .65-.93; standard error of the measurement=6.7%; SDD=18.6%). CONCLUSIONS: The QR&S has good construct validity and good test-retest reliability in lower-limb amputees.

Construct validity and test-retest reliability of the climbing stairs questionnaire in lower-limb amputees.

OBJECTIVE: To investigate the construct validity and test-retest reliability of the Climbing Stairs Questionnaire, a patient-reported measure of activity limitations in climbing stairs, in lower-limb amputees. DESIGN: A cross-sectional study. SETTING: Outpatient department of a rehabilitation center. PARTICIPANTS: Lower-limb amputees (N=172; mean +/- SD age, 65+/-12y; 71% men; 82% vascular cause) participated in the study; 33 participated in the reliability study. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE(S): Construct validity was investigated by testing 10 hypotheses: limitations in climbing stairs according to the Climbing Stairs Questionnaire will be greater in lower-limb amputees who: (1) are older, (2) have a vascular cause of amputation, (3) have a bilateral amputation, (4) have a higher level of amputation, (5) have more comorbid conditions, (6) had their rehabilitation treatment in a nursing home, and (7) climb fewer flights of stairs. Furthermore, limitations in climbing stairs will be related positively to activity limitations according to: (8) the Locomotor Capabilities Index, (9) the Questionnaire Rising and Sitting down, and (10) the Walking Questionnaire. Construct validity was quantified by using the Mann-Whitney U test, Kruskal-Wallis test, and Spearman correlation coefficient. Test-retest reliability was assessed with a 3-week interval and quantified using the intraclass correlation coefficient (ICC). RESULTS: Construct validity (8 of 10 null hypotheses not rejected) and test-retest reliability were good (ICC=.79; 95% confidence interval, .57-.90). CONCLUSION: The Climbing Stairs Questionnaire has good construct validity and test-retest reliability in lower-limb amputees.

Inter- and intra-observer reproducibility and validity of an indirect volume measurement in transtibial amputees.

The objective of the study was to assess the measurement properties of an indirect volumetric measurement using segmental circumferential measurements fitted into a formula of a truncated cone (Sitzia's method) in long-term transtibial amputees. Twenty-eight participants with a transtibial amputation >1 year participated in the study. Two observers measured stump volume twice, two weeks apart, using both Sitzia's method and the water displacement volumetric method (criterion standard test). The mean differences and upper and lower limits of agreement between the water displacement volumetric method and Sitzia's method, between the first and second assessment, and between both assessors were calculated. Intra-class correlation coefficients (ICCs) were derived from random-effects two-way analysis of variance. Inter-observer agreements of both methods were high and ranged from 86-96%. Intra-observer agreement ranged between 57% and 71%. In both methods the inter- and intra-observer differences were not significant. ICCs ranged from 0.88-0.99 and were better for inter-observer compared to intra-observer reproducibility. Lower stump volumes were observed in Sitzia's method compared to water displacement volumetric method, with high ICC's (0.92-0.95) between both methods. Although Sitzia's method systematically underestimates stump volume, it is a reliable and feasible alternative to the criterion standard test. To determine its validity to detect (longitudinal) differences in stump volume, follow-up research is needed in participants with recent amputations.

Measuring activity limitations in walking: development of a hierarchical scale for patients with lower-extremity disorders who live at home.

OBJECTIVE: To develop a hierarchical scale that measures activity limitations in walking in patients with lower-extremity disorders who live at home. DESIGN: Cross-sectional study. SETTING: Orthopedic workshops and outpatient clinics of secondary and tertiary care centers. PARTICIPANTS: Patients (N=981; mean age +/- standard deviation, 58.6+/-15.4 y; 46% men) living at home, with different lower-extremity disorders: stroke, poliomyelitis, osteoarthritis, amputation, complex regional pain syndrome type I, and diabetic and degenerative foot disorders. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: (1) Fit of the monotone homogeneity model, indicating whether items can be used for measuring patients; (2) fit of the double monotonicity model, indicating invariant (hierarchical) item ordering; (3) intratest reliability, indicating repeatability of the sum score; (4) robustness, addressing the clinimetric properties within subgroups of patients; and (5) differential item functioning, addressing the validity of comparisons between subgroups of patients. RESULTS: Thirty-five of 41 dichotomous items had (1) good fit of the monotone homogeneity model (coefficient H=.50), (2) good fit of the double monotonicity model (coefficient H(T)=.33), (3) good intratest reliability (coefficient rho=.95), (4) satisfactory robustness (within subgroups of patients defined by age, sex, and diagnosis), and (5) some differential item functioning (6 items in amputees compared with nonamputees). CONCLUSIONS: A hierarchical scale, with excellent scaling characteristics, was developed to measure activity limitations in walking in patients with lower-extremity disorders who live at home. The measurements should be interpreted cautiously when making comparisons between amputees and nonamputees.
