Metabolic energy expenditure during spring-loaded crutch ambulation.
CONTEXT Individuals using traditional axillary crutches to ambulate expend approximately twice as much energy as individuals who perform able-bodied gait. A relatively novel spring-loaded crutch now being marketed may reduce metabolic energy expenditure during crutch ambulation. This idea, however, had not yet been tested. OBJECTIVE To determine whether the novel spring-loaded crutch reduces ...
متن کاملVertical Displacement of the Center of Mass during Spring-loaded Crutch Ambulation
Approximately 600,000 Americans use crutches each year [1]. A relatively novel spring-loaded crutch design is now being marketed (Figure 1A). The manufacturer (Millennial Medical Inc, Logan, UT, USA) of this crutch design has speculated that because a spring located in the crutch post compresses during crutch-ground contact, crutch length decreases, and less vertical displacement of the whole-b...
متن کاملBiomechanical Evaluation of Crutch Design Variations
The purpose of the study is to evaluate variations in the forces and moments applied to both the axillary (armpit) pad and handgrip of standard axillary crutches. The modified axillary pad was tapered in the front rather than symmetric and the modified handgrip was angled to about 17° rather than horizontal. The crutches used could be fitted with the standard or novel versions of both the axill...
متن کاملA kinematic comparison of spring-loaded and traditional crutches.
CONTEXT A novel spring-loaded-crutch design may provide patients additional forward velocity, relative to traditional axillary crutches; however, this idea has not yet been evaluated. OBJECTIVE To quantify elastic potential energy stored by spring-loaded crutches during crutch-ground contact and determine whether this energy increases forward velocity for patients during crutch ambulation. Be...
متن کاملSpring-loaded Syringe for Multiple Rapid Injections
Mesotherapy refers to multiple injections of small quantity of the drug over a large area. The mesoguns available are expensive and the motor-driven models tends to waste the expensive material to be injected since the plunger stops after injecting without recoil. We searched for a less expensive device which would inject like the mesogun and still not waste the solution. On searching the web, ...
