The Timed Up and Go and Two-Minute Walk Test: Exploration of a method for establishing normative values for established lower limb prosthetic users

Inertial measurement units and normative values enable clinicians to quantify clinical walking tests and set rehabilitation goals. Objectives of this study were (1) to compare time- and distance-based walking tests in individuals with lower limb amputation (iLLA) and normative values following rehabilitation discharge (T1) and 6 weeks after discharge (T2) and (2) to investigate spatiotemporal and foot kinematic parameters over a 6-minute walk test using inertial measurement units. Twelve iLLA participated in this study. Distance, cadence, stance ratio, loading rate ratio, push-up ratio, path length, and minimum toe clearance were analyzed during 6-minute walk test. Nonparametric repeated-measures analysis of variance tests, Bonferroni corrections, were performed. Time of distance-based walking tests diminished at T2 (P < .02). Compared with normative values, walking performance in iLLA was reduced. Cadence at T2 increased significantly (P = .026). Stance ratio increased in both legs at T2 (P < .05). Push-up ratio tended to decrease at T2 in the amputated leg (P = .0003). Variability of path length and minimum toe clearance at T2 were less than at T1 in the nonamputated leg (P < .05). Spatiotemporal improvement at T2 could be due to prosthesis adaptation in iLLA. The lower performance of the functional walk test compared with normative values could be due to amputation and pain-related fatigue.

Lower Limb Amputees

The objective of the trial was to evaluate the effectiveness of a short and intensive physiotherapy programme versus usual care, mainly consisting of walking. Fifty-eight male unilateral lower limb amputees were randomised over intensive care (N = 29) and usual care (N = 29); this study was carried out in a clinical environment, within the premises of the International Committee of the Red Cross, in Southern Myanmar. The amputees in the experimental group received a three-day programme built around 7 specific exercises, lasting approximately one hour altogether. Effects were assessed on: 2-minute walk test, physiological cost index (PCI), amount of weight bearing on both legs, 5 questions of the Functional Measure for Amputees questionnaire and the timed up and go test. Trans-tibial amputees were tested the first day they were fitted and then 2 days later; trans-femoral amputees were tested when walking out of the parallel bars and 4 days later. The experimental group showed significant improvement in the 2-minute walk test (p = 0.02), in the PCI (p = 0.02) and in the maximal weight bearing test on the amputated leg (p = 0.04). Despite limited means, research remains feasible in a developing country; this study has demonstrated that physiotherapy is effective in improving functional performance of lower limb amputees and therefore has its place in every rehabilitation centre.

Резюме. Правильний і обґрунтований вибір інструментальних методів оцінювання функціо-нального стану пацієнта є обов’язковою умовою адекватної фізичної терапії. Особливе місце цей аспект займає в системі нейрореабілітації пацієнтів з хворобою Паркінсона в Україні, оскільки на сьогодні кількість осіб, що потребують систематичної фізичної терапії, сягає 23 900 тис. Наростаюча маніфестація моторних і немоторних симптомів при хворобі Паркін-сона, від яких часто вирішальною мірою залежить тяжкість стану пацієнта, негативно впливає на якість його життя. Наявні функціональні порушення, які є самостійними проявами хвороби Паркінсона, вимагають специфічного підходу до комплексного інструментального досліджен-ня цих порушень для визначення диференційно-діагностичних критеріїв та оцінювання впливу фізіотерапевтичного втручання. Мета. Проаналізувати наявні інструменти оцінювання впливу фізичної терапії на осіб з хворобою Паркінсона. Методи. Теоретичний аналіз та узагальнення зарубіжних даних спеціальної науково-методичної літератури з питань застосування інстру-ментів оцінювання при хворобі Паркінсона та їх інформативності і надійності у фізичній терапії. Результати. Представлені дані свідчать, що ефективність запроваджених заходів фізичної терапії при хворобі Паркінсона залежить від правильно підібраних інструментів оцінювання, які дозволяють оцінити моторні і немоторні проблеми через призму життєдіяльності і якості життя пацієнта. Основним інструментом оцінювання для вирішення цього питання вважаєть-ся Уніфікована рейтингова шкала хвороби Паркінсона MDS-UPDRS, яка дозволяє об’єктивно оцінити моторні і немоторні аспекти життя пацієнта і його рухову активність. Оскільки наявні моторні й аксіальні рухові порушення негативно впливають на повсякденну функціональну активність пацієнта, для верифікації цих порушень пропонують використовувати тест для оці-нювання часу підйому і ходьби (Timed Up and Go (TUG)); тест з подвійним завданням (Dual-Task TUG (TUG-DT)) та шкалу рівноваги Берга (Berg Balance Scale (BBS)). Але виходячи з того, що ці тести недостатньо чутливі до невеликих змін у рухливості при хворобі Паркінсона, особливо на середніх і пізніх стадіях захворювання, їх доцільно поєднувати з одним із кількісних тестів для оцінювання ходьби: 10-метровим тестом ходьби (10 Meter Walk Test (10MW)) та 6-хвилинним тестом ходьби (Six Minute Walk Distance (6MWT)). Поняття «життєдіяльність» включає в себе не тільки переміщення, її оцінювання має бути доповнено аналізом ступеня впливу наявних по-рушень на повсякденну діяльність, тобто на якість життя пацієнта. Найбільш інформативними інструментами для проведення цього аналізу є універсальні і специфічні при хворобі Паркінсо-на опитувальники з метою оцінювання стану здоров’я SF-36, EuroQOL (EQ-5D) і PDQ-39 (The Parkinson’s Disease Questionnaire). Результати аналізу та узагальнення даних науково-мето-дичної літератури дають підставу встановити, що маніфестація порушень та їх варіабельність при хворобі Паркінсона стають серйозною проблемою у досягненні кінцевого результату за-проваджених заходів фізичної терапії на всіх стадіях захворювання. Використання в комплексі стандартної експертно-реабілітаційної діагностики спеціальних інструментів оцінювання дозволяє об’єктивізувати оцінювання клінічної інформації та стимулює розроблення особисто-орієнтованих реабілітаційних стратегій із застосуванням заходів фізичної терапії, спрямованих на покращення якості життя пацієнтів з хворобою Паркінсона. Ключові слова: хвороба Паркінсона, фізична терапія, якість життя, інструменти оцінювання, достовірність, надійність, валідність.

Fall-risk classification is a challenging but necessary task to enable the recommendation of preventative programs for individuals identified at risk for falling. Existing research has primarily focused on older adults, with no predictive fall-risk models for lower limb amputees, despite their greater likelihood of fall-risk than older adults. In this study, 89 amputees with varying degrees of lower limb amputation were asked if they had fallen in the past 6 months. Those who reported at least one fall were considered a fall risk. Each participant performed a 6 minute walk test (6MWT) with an Android smartphone placed in a holder located on the back of the pelvis. A fall-risk classification method was developed using data from sensors within the smartphone. The Ottawa Hospital Rehabilitation Center Walk Test app captured accelerometer and gyroscope data during the 6MWT. From this data, foot strikes were identified, and 248 features were extracted from the collection of steps. Steps were segmented into turn and straight walking, and four different data sets were created: turn steps, straightaway steps, straightaway and turn steps, and all steps. From these, three feature selection techniques (correlation-based feature selection, relief F, and extra trees classifier ensemble) were used to eliminate redundant or ineffective features. Each feature subset was tested with a random forest classifier and optimized for the best number of trees. The best model used turn data, with three features selected by Correlation-based feature selection (CFS), and used 500 trees in a random forest classifier. The resulting metrics were 81.3% accuracy, 57.2% sensitivity, 94.9% specificity, a Matthews correlation coefficient of 0.587, and an F1 score of 0.83. Since the outcomes are comparable to metrics achieved by existing clinical tests, the classifier may be viable for use in clinical practice.

Abstract Background: Persons with multiple sclerosis (MS) commonly have difficulty walking. The 6-Minute Walk Test (6MWT) assesses functional capacity but may be considered burdensome for persons with MS, especially those with higher disability levels. The 2-Minute Walk Test (2MWT) may be an alternative measure to the 6MWT. The purpose of this study was to investigate the validity of the 2MWT in persons with MS. Methods: Twenty-eight ambulatory persons with MS aged 18 to 64 years participated in this cross-sectional study. Participants completed five measures of walking performance (2MWT, 6MWT, usual and fast gait speed, and Timed Up and Go test) and two functional measures (Berg Balance Scale and five-times sit-to-stand test) during a testing session. Participants were classified into two subgroups based on Disease Steps scale classification. Results: The 2MWT was significantly correlated with the 6MWT (r = 0.947), usual gait speed (r = 0.920), fast gait speed (r = 0.942), the Timed Up and Go test (r = −0.911), and other functional measures. The 2MWT explained 89% of the variance seen during the 6MWT. The distances completed on the 2MWT and 6MWT accurately distinguished the subgroups. Conclusions: This study demonstrated good construct and discriminant validity of the 2MWT in persons with MS, providing an efficient and practical alternative to the 6MWT. Validation of the 2MWT with other functional measures further supports these findings.

Background: The gold standards for assessing ambulation are the Expanded Disability Status Scale (EDSS) and the Timed 25-Foot Walk (T25FW) test. In relation with these measures, we assessed the reliability and validity of four clinical gait measures: the Timed Up and Go (TUG) test, the Dynamic Gait Index (DGI), the 2-Minute Walk Test (2MWT), and the 6-Minute Walk Test (6MWT). Patient self-report of gait was also assessed using the 12-item Multiple Sclerosis Walking Scale (MSWS-12). Methods: Individuals 20 years or older with a diagnosis of multiple sclerosis (MS) and an EDSS score of 2.0 to 6.5 completed the MSWS-12, T25FW test, TUG test, DGI, 2MWT, and 6MWT. All the tests were repeated 2 weeks later at the same time of day to establish their reliability and concurrent validity. Predictive validity was established using the EDSS. Results: Forty-two patients with MS were included. All measures showed high test-retest reliability. The TUG test, 2MWT, and 6MWT were significantly correlated with the T25FW test (Spearman ρ = −0.902, −0.919, and −0.905, respectively). The EDSS was also significantly correlated with all the walking tests. The MSWS-12 demonstrated the highest correlation to the EDSS (ρ = 0.788). Conclusions: The TUG test, the DGI, the 2MWT, and the 6MWT exhibited strong psychometric properties and were found to be significant predictors of the EDSS score. Use of these tests to prospectively monitor the effects of medical and rehabilitation treatment should be considered in the comprehensive care of patients with MS.

Background/aims Polymyositis is an inflammatory myopathy characterised by chronic and progressive muscle weakness. This case report discusses a 61-year-old African-American man with polymyositis. Even though pharmacological and physical therapy interventions had previously been prescribed, they had not been beneficial. This case report examined the effects of a functional electric stimulation-assisted exercise programme. Methods The patient was treated in an outpatient clinic two times a week and performed exercises three times a week on alternating days for 36 weeks. In the clinic, he received functional electrical stimulation-assisted strengthening to quadriceps, hamstrings and gluteus maximus while performing activities such as sit to stand, squats, bridging and cycling. For endurance training, he ambulated on the clinic track with a neuroprosthetic to assist with dorsiflexion in the swing phase of gait. At home, he performed lower extremity and core strengthening exercises. Measures to evaluate the intervention included the Manual Muscle Test, functional mobility (Timed Up and Go Test), balance (Berg Balance Scale, Activities of Balance Confidence Scale), endurance (Six-Minute Walk Test with a modified Borg scale) and gait speed (10-Metre Walk Test). Results After 36 weeks of treatment, the patient had made gains in strength in all muscle groups in his bilateral lower extremities except hip extensors. Timed Up and Go time decreased by 14.01 seconds. The patient changed from a medium fall risk to low fall risk on the Berg Balance Scale and his confidence increased by 46.2% on the Activities of Balance Confidence Scale. Furthermore, he gained endurance as exhibited by his increased distance of 289 feet on the Six-Minute Walk Test and his modified Borg score decreased from 4 out of 10 to 2 out of 10. The patient made subjective and objective gains in gait speed, increasing from 0.18 metres per second at his initial examination to 0.50 metres per second. Conclusions This case study demonstrates that functional electrical stimulation-assisted exercise, conducted in an outpatient setting, can improve strength and functional mobility in an individual with polymyositis without detrimental effects.
