Lower-extremity constraint-induced movement therapy improved motor function, mobility, and walking after stroke.

BACKGROUND: To regain the ability to walk is one of the most commonly stated goals for people who have had a stroke due to its importance in everyday life. Walking ability affects patients' mobility, self-care, and social lives. Constraint-induced movement therapy (CIMT) is known to be effective in improving upper extremity outcomes post-stroke. However, there is insufficient evidence regarding its efficacy in improving lower extremity outcomes. AIM: To investigate whether a highly intensive CIMT for lower extremity (LE-CIMT) function post-stroke can improve motor function, functional mobility, and walking ability. Furthermore, it also aimed to investigate whether age, gender, stroke type, more-affected side, or time after stroke onset affect the efficacy of LE-CIMT on walking ability outcomes. DESIGN: Longitudinal cohort study. SETTING: Outpatient clinic in Stockholm, Sweden. POPULATION: A total of 147 patients mean age 51 years (68% males; 57% right-sided hemiparesis), at the sub-acute or chronic phases post-stroke who had not previously undergone LE-CIMT. METHODS: All patients received LE-CIMT for 6 hours per day over 2 weeks. The Fugl-Meyer Assessment (FMA) of the lower extremity, Timed Up and Go (TUG) test, Ten-Meter Walk Test (10MWT), and six-Minute Walk Test (6MWT) were used to assess functional outcomes before and directly after the 2-week treatment was complete as well at 3-month post-intervention. RESULTS: Compared to baseline values, FMA (P<0.001), TUG (P<0.001), 10MWT (P<0.001) and 6MWT (P<0.001) scores were statistically significantly improved directly after the LE-CIMT intervention. These improvements persisted at the 3-month post-intervention follow-up. Those who completed the intervention 1-6 months after stroke onset had statistically significant larger improvements in 10MWT compared to those who received the intervention later than 6 months after stroke onset. Age, gender, stroke type, and more-affected side did not impact 10MWT results. CONCLUSIONS: In an outpatient clinic setting, high-intensity LE-CIMT statistically significant improved motor function, functional mobility, and walking ability in middle-aged patients in the sub-acute and chronic post-stroke phases. However, studies with more robust designs need to be conducted to deepen the understanding of the efficacy of LE-CIMT. CLINICAL REHABILITATION IMPACT: High-intensity LE-CIMT may be a feasible and useful treatment option in outpatient clinics to improve post-stroke walking ability.

I exercise to postpone death - Interviews with persons with hip and/or knee osteoarthritis who are attending an osteoarthritis school.

BACKGROUND: Physical activity (PA) and exercise constitute the first line of treatment for osteoarthritis (OA) of the hip and/or knee. Even though the symptoms may vary, OA should be considered a chronic disease and therefore PA and exercise should be performed lifelong. That needs knowledge and motivation. PURPOSE: The purpose of this study was to explore and create a deeper understanding of the motivational processes for PA and exercise for persons with hip and/or knee OA who have participated in a self-management program OA school that included long-term exercise supervised by physical therapists. METHODS: Twenty-two in-depth interviews were conducted with 18 participants recruited from the OA school at a Physical Therapy Rehabilitation Clinic in Sweden. The interviews were analyzed with qualitative content analysis. RESULTS: The analysis resulted in one main theme, Developing health literacy to encourage motivational processes for PA and exercise in OA and four themes: 1) meeting an established self-management program; 2) carrying my life history; 3) understanding the intelligence of the body; and 4) growing in existential motivation. CONCLUSION: Motivation for being physically active and to exercise, the life history in relation to PA and what creates existential motivation are important areas to ask questions about when people come to OA schools. Knowledge about the signals of the body connected to OA should be implemented in OA schools in order to motivate people to live an active life despite OA. Health literacy and the awareness of how PA can postpone death are likely to be important for existential motivation.

Sever's injury: a clinical diagnosis.

BACKGROUND: The diagnosis of Sever's injury (apophysitis calcanei) has previously been partly based on radiographic findings in the calcaneal apophysis. Sclerosis and fragmentation have been supposed to represent signs of inflammation due to tractions from the Achilles tendon. The clinical findings, diagnostic criteria, and studied population are often poorly defined. We sought to define diagnostic criteria by analyzing clinical and radiographic characteristics in a population with Sever's injury and to compare the findings with those of a control group of matched, symptom-free children. METHODS: We assessed 30 consecutive children with Sever's injury with high levels of pain but high physical activity levels in sports activities and 15 pain-free matched controls. RESULTS: One-leg heel standing showed 100% sensitivity; the squeeze test, 97%; and the palpation test, 80%. All three tests showed 100% specificity. All of the patients and controls showed increased density of the apophysis. Half of the pain-free controls showed fragmentation versus almost 90% of children with heel pain. CONCLUSIONS: The diagnosis of Sever's injury is clinical, not radiologic. Radiologic findings of increased density and fragmentation are found also in pain-free controls with high levels of physical activity and may, therefore, represent normal growth and development. We suggest that the diagnosis of Sever's injury should be based on patient history and the results of two specific clinical tests.

Effects of lower limb intensive mass practice in poststroke patients: single-subject experimental design with long-term follow-up.

OBJECTIVE: To investigate the effects of two weeks of intensive mass practice with a constraint-induced movement therapy approach for the lower extremity in five chronic poststroke patients, and the persistence of effects at three and six months. DESIGN: A single-subject experimental design (SSED) was used with an AB design and follow-ups three and six months later. SETTING: Outpatient rehabilitation at Torsby Hospital in Sweden. MAIN MEASURES: Motor function in lower extremity, mobility, dynamic balance, weight-bearing symmetry and walking ability were measured on six occasions during two weeks (A phase), with the Fugl-Meyer assessment for lower extremity, the Timed Up and Go, the Step Test, the Timed Walking Test and the Six-Minute Walk Test. During the intervention's B phase, six measurements were performed with the same time intervals as in the A phase. There were follow-ups three and six months later. INTERVENTION: The intervention (B phase) consisted of bicycling, training in water, strength training, standing weight-bearing, walking up and down stairs, walking indoors and outdoors and flexibility training of the lower extremity, on all weekdays, 6 h a day for two weeks. RESULTS: The results showed improvements in 23/30 variables (77%), 12 of them statistically significant (52%). At follow-up, 22/23 improvements persisted. For example, three of five subjects walked significantly further after the intervention and the follow-ups showed that they still walked further than before the intervention. CONCLUSION: Intensive mass practice with constraint-induced movement therapy for the lower extremity can improve motor function, mobility, dynamic balance, weight-bearing symmetry and walking ability in chronic poststroke patients. Long-term follow-up showed that the effects persisted for these five subjects.

Hip disability and osteoarthritis outcome score (HOOS)--validity and responsiveness in total hip replacement.

BACKGROUND: The aim of the study was to evaluate if physical functions usually associated with a younger population were of importance for an older population, and to construct an outcome measure for hip osteoarthritis with improved responsiveness compared to the Western Ontario McMaster osteoarthritis score (WOMAC LK 3.0). METHODS: A 40 item questionnaire (hip disability and osteoarthritis outcome score, HOOS) was constructed to assess patient-relevant outcomes in five separate subscales (pain, symptoms, activity of daily living, sport and recreation function and hip related quality of life). The HOOS contains all WOMAC LK 3.0 questions in unchanged form. The HOOS was distributed to 90 patients with primary hip osteoarthritis (mean age 71.5, range 49-85, 41 females) assigned for total hip replacement for osteoarthritis preoperatively and at six months follow-up. RESULTS: The HOOS met set criteria of validity and responsiveness. It was more responsive than WOMAC regarding the subscales pain (SRM 2.11 vs. 1.83) and other symptoms (SRM 1.83 vs. 1.28). The responsiveness (SRM) for the two added subscales sport and recreation and quality of life were 1.29 and 1.65, respectively. Patients 66 years of age (range 67-85) (Pain SRM 2.60 vs. 1.97, other symptoms SRM 3.0 vs. 1.60, activity of daily living SRM 2.51 vs. 1.52, sport and recreation function SRM 1.53 vs. 1.21 and hip related quality of life SRM 1.95 vs. 1.57). CONCLUSION: The HOOS 2.0 appears to be useful for the evaluation of patient-relevant outcome after THR and is more responsive than the WOMAC LK 3.0. The added subscales sport and recreation function and hip related quality of life were highly responsive for this group of patients, with the responsiveness being highest for those younger than 66.

Promising outcome of a hip school for patients with hip dysfunction.

OBJECTIVE: To evaluate, in an exploratory study, a hip school led by physical therapists for patients with hip dysfunction including pain. METHODS: Physicians in primary care and orthopedic units consecutively recruited patients by residential area to a treatment group (T group; n = 77) and a control group (C group; n = 68), mean age 61.8 years, 59 men, 86 women. Ninety-nine of the 145 subjects had radiologic hip osteoarthritis. Outcome measures were the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Nottingham Health Profile (NHP). RESULTS: After hip school (6 months) the T group showed greater reduction on the subscales of pain and activity limitations (WOMAC) than the C group. The subscales sleep disturbances, pain, and physical mobility (NHP) showed improvement for the T group compared with at start. The results for the T group persisted after an additional 6 months. CONCLUSION: A hip school may reduce pain and activity limitations and improve health-related quality of life for patients with hip dysfunction including pain.

Examination of passive ROM and capsular patterns in the hip.

BACKGROUND AND PURPOSE: The present study was conducted to examine passive hip range of motion (PROM) for patients with hip dysfunction, including pain, with or without hip osteoarthritis, to arrange and describe PROM patterns and to count the number of hips presenting Cyriax's and Kaltenborn's capsular patterns. METHOD: The study is theory-testing, observational, cross-sectional and descriptive. One hundred and sixty-eight patients (mean age 61.7 years, range 36-90 years), 50 with no hip osteoarthritis, 77 with unilateral hip osteoarthritis and 41 with bilateral osteoarthritis, based on radiological reports, were consecutively recruited by physicians in primary health care and orthopaedic settings. One examiner tested PROM bilaterally, by use of a goniometer and a standardized protocol. PROM limitations were calculated by comparing norms from the symptom-free hips (n = 100) in the study, from Kaltenborn and, in patients with unilateral hip osteoarthritis (n = 77), from the non-osteoarthritis hip. The limitations were arranged by size in PROM patterns. The patterns and the numbers of hips with patterns corresponding to Cyriax's and Kaltenborn's capsular patterns were counted. RESULTS: Between 68 and 138 PROM patterns were identified by use of different PROM norms for defining limitations. Few osteoarthritis hips showed Cyriax's capsular pattern and none Kaltenborn's capsular pattern. CONCLUSIONS: The concept of capsular pattern for the hip should be re-examined. No support was found in the present study for its existence. It is impossible to anticipate radiological evidence of hip osteoarthritis from the multitude of PROM patterns. Every patient should be regarded as unique.

Hip disability and osteoarthritis outcome score. An extension of the Western Ontario and McMaster Universities Osteoarthritis Index.

To further develop the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC LK 3.0) for people with hip disability with or without hip osteoarthritis (OA), 52 subjects (median age 64 yrs, 35 women) answered a version of the Index with additional dimensions, twice, with a one-week interval. Reproducibility, percentage of zero scores (best possible scores), mean score of symptoms, and importance, were analyzed. This resulted in the Hip disability and osteoarthritis outcome score (HOOS LK 1.1), a 39-item questionnaire with five separate sub-scales. There were higher median scores (more symptoms) for three of HOOS sub-scales Pain, Activity limitations--sport and recreation, and Hip-related Quality of life compared to those in the WOMAC, improving the ability to assess change in patients over time. The HOOS appears to be an evaluative instrument for assessing important self-rated hip problems for people with hip disability with/without hip OA, but additional studies are needed.
