Webinar Description
Walking during body-weight supported treadmill training and acute responses to varying walking speeds and body-weight support in ambulatory patients post-stroke. Aaslund MK, Helbostad JL, Moe-Nilssen R. (2013). Physiother Theory Pract 29(4):278-89 Summary by Nechama Karman, PT, MS, PCS A convenience sample of 44 ambulatory (FAC 3, 4 and 5) patients who could walk 10m without walking aids, and were medically stable post-stroke between 16 and 85 years of age, on an acute stroke unit and a rehabilitation unit completed this study. This cross-sectional repeated-measures design was used to assess ambulating patients post-stroke while walking overground and on a treadmill. Overground walking was performed for 11m, of which the middle 7m were analyzed, at usual speed (preferred) , “slower than usual” (slow) and “as fast as safe without running” (fast) walking speeds. Two walking trials were collected from each participant, and the average of the 2 intervals were used for analysis. These walking speeds were replicated on the treadmill (following familiarization trial of 3-5 min) with 20% and with 40% BWS in randomized order in 90 second increments (at each speed and BWS condition) to allow for comparison of the effects of speed and body weight support on the treadmill with the overground walking condition. Walking data were collected with the person walking without upper extremity support, and without assistance. The last 30 seconds of each condition were used for kinematic analysis. A 6-degrees of freedom inertial sensor was placed over the lumbar region to collect accelerometric and orientation data which was used to calculate kinematic outcomes. Outcome measures: were completed for the last 30 seconds of each walking condition, using data from inertial sensor placed in the lumbar region. They included: Trunk acceleration: expressed as root mean square values of amplitudes for each test interval. Step time: calculated using autocorrelation procedure Cadence: calculated using step time and walking distance. Average step length: calculated using step time and walking distance. Interstep and interstride trunk acceleration regularity: using autocorrelation procedure (autocorrelation coefficient of 1 indicates perfect replication of neighboring steps). Trunk asymmetry: difference between interstride and interstep trunk regularity: reflects additional variability between left and right steps Walk ratio: step length:cadence (an index for temporal and spatial coordination at a given speed) d.
