“…This method has been shown to provide between 20-30 degrees of elbow flexion in about 94% of normal subjects. 24 Differences in subject arm lengths and body weights were accounted for by normalizing the moments with respect to these quantities. Forward placement of the walker, cadence, and stride length were not controlled.…”

“…The walker was adjusted to an appropriate height such that the top of the walker was aligned with the ulnar styloid when the subject stood beside the frame with arms held loosely in a relaxed position. 23,24 Using a noninstrumented, practice walker, the subject was taught a three-count, delayed, five-point gait. They lifted the standard walker, moved it forward about 0.20 to 0.30 m in front of their toes without overstretching, took two steps into the frame moving the involved right lower limb first, and then repeated the process.…”

While walkers are commonly prescribed to improve patient stability and ambulatory ability, quantitative study of the biomechanical and functional requirements for effective walker use is limited. To date no one has addressed the changes in upper extremity kinetics that occur with the use of a standard walker, which was the objective of this study. A strain gauge-based walker instrumentation system was developed for the six degree-of-freedom measurement of resultant subject hand loads. The walker dynamometer was integrated with an upper extremity biomechanical model. Preliminary system data were collected for seven healthy, right-handed young adults following informed consent. Bilateral upper extremity kinematic data were acquired with a six camera Vicon motion analysis system using a Micro-VAX workstation. Internal joint moments at the wrist, elbow, and shoulder were determined in the three clinical planes using the NOT THE PUBLISHED VERSION; this is the author's final, peer-reviewed manuscript.

“…However, there is some disagreement about cane length. Kumar et al 14) proposed it should be the height of the distal wrist crease. The reasons for this are mainly due them having only focused on the elbow flexion of normal elderly people when they used a cane.…”

“…The patient stood erect wearing comfortable shoes, and the length of the cane was adjusted so that the top of the cane corresponded to the top of the greater trochanter (GT), 5 cm above the greater trochanter (A5GT), or 10 cm above the greater trochanter (A10GT). The lower tip of the cane was placed at a point 6 inches lateral to the little toe 14) . The subjects wore their own shoes and the insoles which were trimmed to their shoe sizes.…”

“…A commonly used method for determining the ideal cane length is to measure the distance from the floor to the greater trochanter 12,13) . However, Kumar et al 14) reported that the proper cane length should be measured from the floor to the distal wrist crease, and that was a more comfortable length for countering weak balance during walking than to the greater trochanter. Recent evidence 15) suggests that the cane length ought to be adjusted to the individual's arm length because of the unique physical characteristics of individuals.…”

Comparison of the Plantar Pressure Distributions at Different Cane Lengths

et al. 2012

Abstract.[Purpose] The purpose of this study was to compare plantar pressure distributions of the affected side of stroke patients during walking with canes of three different cane lengths.[Subjects] Thirty-four stroke patients participated in this study. [Method] The three different lengths of cane were: to the top of the greater trochanter, 5 cm above the greater trochanter, and 10 cm above the greater trochanter. The measured parameters were foot contact area, length, width, pressure, and the center of pressure trajectory during the stance phase, from heel-strike to toe-off.[Results] Our data revealed significant increments in the contact width and pressure of the hind foot at the cane length of 10 cm above the greater trochanter. Anterior/posterior center of pressure trajectory also significantly increased at cane lengths of 5 and 10 cm of above the greater trochanter.[Conclusion] The plantar pressure distribution for cane lengths above the greater trochanter were clinically beneficial and more effective at increasing weight shifting to the affected hind foot and harmonizing paralyzed heel strike with better displacement of pressure.
