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.

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.

Objective: To find out the current practice patterns of Physiotherapists in Phase I Cardiac Rehabilitation of patients following Cardiac Surgery (CABG/Valve Surgery). Materials and Methods: The cross sectional survey included 600 cardio-pulmonary physiotherapists working in Cardiac Care Unit, who filled questionnaires sent to them through e-mail. Results: 252 completed questionnaires were received back, the response rate being of 42 %, with a major portion of responses coming from Maharashtra, Karnataka and Andhra Pradesh. More than 80 % of physiotherapists assess and treat the patient Pre- Operatively. More than 90% of physiotherapists performed Cardiac Rehabilitation Post-Operatively. Cardiac Rehabilitation Treatment Techniques predominantly focused on Breathing Exercises (96.7%), Incentive Spirometry (91.1%), Coughing and Huffing (83.3%), Thoracic Expansion Exercises (82.13%), Positioning (71.16%), Percussion and Vibration (63.6%), Modified Postural Drainage (41.2%), active exercises of the upper limb (89.13%), and lower limb exercises (89.3%). Dangling the lower limb (69%) was started on Post –Operative day 2. Room and corridor mobilisation (73.8%) began on third Post-Operative day. 29.4% Stair case climbing was started on fourth post-operative day. 73.8% of patients practiced 6-minute walk test prior to discharge. Most commonly used sternal precautions were Supported Coughing (96.0%) and Lifting Restrictions (82.5%). Conclusion: Phase I cardiac rehabilitation adopted by physiotherapists for cardiac surgery patients involves treatment which mainly focused on cough and huff techniques, breathing exercises and thoracic expansion exercises. On Post-Operative day 2, dangling the lower limb and room ambulation started on third post-Operative day 3. The training for climbing stairs started on fourthpost-operative day. The most commonly used sternal precautions were supported coughing and lifting restrictions whereas 6-minute walk test was use to assess exercise tolerance,prior to discharge.

The purpose of this study was to determine whether measures of impairment (i.e., muscle strength, balance), personal factors (i.e., comorbidities, demographic information) and amputation specific variables (i.e., time since amputation, cause of amputation, level of amputation) were able to predict performance on the six-minute walk test, a measure of activity limitation, in individuals with lower limb amputation. A total of 72 individuals with lower limb amputation ranging in age from 21–83 were tested for balance, limb muscle strength and function. Medical comorbidities were recorded and activity limitation was measured using the six-minute walk test. Data were analyzed and multivariate relationships were examined using multiple linear regression. Impairment variables of strength, balance, subject demographics, time since amputation, cause of amputation and level of amputation were all significant predictors and explained 72% of the variance in the outcome variable. Strength of the hip extensors was the strongest predictor, accounting for 30.9% of the total variance. Multiple factors impact six minute walk scores in individuals with lower limb amputation. Impairments in hip strength and balance appear to be the two most significant. The findings of this study support the use of the six-minute walk test to underscore impairments of the musculoskeletal system that can affect ambulation ability in the amputee.

Background: Walking speed is considered the sixth vital sign because it is a valid, reliable, and sensitive measure for assessing functional status in various populations. Purpose: The current study assessed agreement in walking speed using the 6-meter walk test, (6MWT) 10-meter walk test (10MWT), 2-minute walk test (2minWT), and 6-minute walk test (6minWT). We also determined differences in walking speed. Methods: Seventy-three healthy adults (44 females, 29 males; mean [SD] age=31.36 [10.33] years) participated. Lafayette Electronic timing devices measured walking speed for the 6MWT and 10MWT. Measuring wheels and stopwatches measured walking distance and speed for the 2minWT and 6minWT. Participants completed 1 trial, and all tests were administered simultaneously. Results: The intraclass correlation coefficient (2, 4) for the different measures of walking speed was excellent at 0.90 (95% confidence intervals, 0.86-0.93). The correlation was 0.95 between 6MWT and 10MWT, 0.94 between 2minWT and 6minWT, 0.67 between 6MWT and 2minWT, 0.63 between 10MWT and 2minWT, and 0.59 between 10MWT and 6minWT (all p < 0.05). No differences in walking speed were found between the four walking tests. Conclusion: Administration of any of the four walking tests provided reliable measurement of walking speed.

Walking difficulty of childhood stroke due to Moya-moya disease needs functional rehabilitation to recover to a normal state of walking. Task related circuit training program is one of the rehabilitation programs that improve functional strength of lower limb muscles to aid in improved walking ability. This case report aimed at investigating the effectiveness of task related circuit training on walking ability of a 9 years old female child diagnosed with stroke due to Moya-moya Disease. The child was attending Indoor rehabilitation services, Department of Occupational Therapy, National Institute for Locomotor Disabilities, Kolkata, West Bengal. Baseline measurement of the child’s lower limb muscle strength, 10m walk test, 6-minute walk test was done prior to the circuit training. After baseline measurement, the child was explained the sequence of tasks to be used in circuit training and was given individualized task related circuit training for a session of 45 minutes, 3 days per week for 08 weeks. Post training the child showed improvement in lower limb muscle strength, 10m walk test (walking speed) and 6-minute walk test (walking endurance), thereby an improved walking ability.
