A Study on Stair-climbing Performance of Articulated-tracked Mobile Robot

Abstract: The stair-climbing ability is one of important obstacle negotiation performances of robot.By analyzing aspects of the change of center of mass during stair-climbing,and stability of motion,this paper presents a series of kinematics simulation experiments of stair-climbing motion to optimize parameters.The simulation can also help to improve the feasibility of the design and the stability of motion.

Dynamic Assessment in Patients Following Bone-Patellar Tendon-Bone Autograft Anterior Cruciate Ligament Reconstruction

Abstract: Background: The knee's passive movement is insufficient to determine function in patients following ACL reconstruction. Hypothesis: We hypothesize that there are kinematic differences in the lower extremities (LE) during stair climbing and ground level walking following ACL surgery between the intact and reconstructed sides. Study Design: This was a retrospective cohort study. Eleven patients with an average age of 15.3 years at the time of their ACL reconstructive surgery (BPTB autograft) participated in the study. Methods: Patients were followed for at least 2 years post surgery. The subjects underwent a non-weight bearing ability test to reproduce predetermined knee joint positions. Their LE's velocity and joint kinematics were then measured during level ground walking and on a set of custom designed stairs as they ascended and descended. Results: During level ground walking the maximum internal rotation at the ankle during the swing phase on the reconstructed side increased significantly from 2.3o to 19.9 o compared to the unreconstructed limb (P=0.04). The leading reconstructed knee during stair ascent exhibited less knee flexion as compared to the unreconstructed knee for each step (1 st step: 74.2o vs 81.5o; 2 nd step:93.6o vs 97.6o; 3 rd step: 48o vs 53.5o; 4 th step: 72.5o vs 78.1o; p<0.05). Conclusions: A two-year follow-up study in adolescents who had a bone-patellar tendon-bone autograft demonstrated that they had normal knee proprioception and 3D joint rotations of the LE, while showing an alteration of the ankle and knee kinematics during walking or ascending stairs.

Improved learning of sequential behaviour during cane gait training or stair climbing after femoral neck fracture: an implication for donepezil for very mild Alzheimer's disease.

Abstract: An 82-year-old, right-handed woman showed decreased learning of sequential behaviours after a right femoral neck fracture. After graduating from high school, the patient worked as a primary school teacher. There were no remarkable past medical history. She maintained her ability to perform activities of daily living and walked independently. She exhibited no apparent signs of dementia and took care of her household duties. Furthermore, she volunteered at a town office to prepare meals for elderly people living alone. One day, she drove to deliver dinner to an elderly woman living alone in the community and fell on the icy pavement when she got out of the car. She experienced a right femoral neck fracture and underwent bipolar hip arthroplasty (X = time of fracture, X + 3 month = 3 months after fracture, and so on). She began to use a walker on the 6 days after starting rehabilitation. No neurological findings were observed. The patient began rehabilitation involving range-of-motion training with a physical therapist, lower-limb muscle training, basic activities training, gait training with a T-cane, and climbing up and down stairs. The training programmes specific to sequential behaviours for T-cane gait on level ground and climbing up and down stairs using a T-cane and handrail (2 steps/1 stair) were unsuccessful. The sequential behaviour for T-cane gait on level ground was performed as follows: (i) T-cane; (ii) affected leg; and (iii) unaffected leg in case. The sequential behaviour for climbing up and down stairs was as follows: (i) T-cane up a step; (ii) unaffected leg up a step; (iii) affected leg up a step; (iv) T-cane down a step; (v) affected leg down a step; and (vi) unaffected leg down a step. However, the patient appeared to not understand the order and took 45 days to achieve the supervision level with gait training on level ground and the aid-requiring level in climbing up and down stairs. Usually, it takes patients fewer than 30 days to learn these behaviours. At discharge (X + 1.5 months), the Barthel Index was 85/100. In addition, the sequential movement of climbing up and down stairs with a T-cane remained insufficient. These findings indicated that the patient was still at risk of fall. One month after discharge (X + 2.5 months), the patient visited the hospital alone by bus without appointment. According to a physical therapist who did not treat the patient, ‘As she tried to climb up and down the stairs by herself, I asked her to stop the training for a while because she was likely to fall down the stairs’. However, the patient disagreed with the staff. Moreover, the patient explained that she visited the hospital without appointment because her niece had discussed her going to the hospital with her care manager 2 days earlier. She said with anger, ‘They forced me to go to a day care that I did not want to go to, and I felt sad’. In addition, she said, ‘I fell from a bus step when I got off the bus, but it did not hurt me’. We again warned her that she was at risk of fall because she had not completely mastered the movement of climbing up and down stairs, and she understood. When we confirmed the incident at a later date, the patient said, ‘I walked 40–50 min to the bus stop, which was approximately 1.5 km from my house. I then got on a bus and fell again when getting off the bus’. She explained that she undertook this trip because she wanted to know how if she was able to do so. Overestimating her physical ability, she scored 100 on the Barthel Index. The patient could prepare meals, but the daily menu was virtually the same and undernutrition was observed. She was certified as Needed Support 1, Impairment Level of Dementia I, Disability Level A2

Effect of Stair Climbing on Selected Endurance Parameters among Football Players

Abstract: Objective: The purpose of the study is to find out the effects of stair climbing on selected endurance parameters such as cardio respiratory endurance and muscular endurance among football players. Methods: Thirty male football players aged between 18 to 25 years, studying in the Department of Physical Education and Sports Science, Annamalai University were selected. The subjects were divided into two equal groups of fifteen subjects each, namely stair climbing group and control group. The stair climbing group was trained for three alternative days in a week for twelve weeks. Set per exercise per session at 60 to 80% with a progressive increase in load with the number of weeks. Cardio respiratory endurance and muscular endurance were selected as criterion variables. Statistics: Cardio respiratory endurance and muscular endurance were tested before (pre) and after (post) the training programme for both experimental and control group by using cooper’s 12 minutes run/walk test and Bent knee sit- ups respectively. ANCOVA was used to find out the significant difference if any between the groups Results: The results of this study indicate that the stair climbing group has significantly improved the selected dependent variables namely cardio respiratory endurance and muscular endurance. However control group did not show any improvement on the selected variables as it was not involved in any of the specific training program Conclusion:  The result of this study shows that, the stair climbing programme has significant improvement on selected endurance parameters such as cardiorespiratory endurance and muscular endurance among football players as compared to control group.
