Abstract
A walking state measurement device according to the present invention includes: at least one memory storing a set of instructions; and at least one processor configured to execute the set of instructions to: estimate a floor reaction force by use of at least either of motion data and lower limb vertical load data of a walker, and outputting the floor reaction force as floor reaction force data; and calculate a walking state of the walker by use of at least either of the motion data and the floor reaction force data, and outputting the walking state.
Claims19
A walking state measurement device comprising:
- at least one memory storing a set of instructions;
- and
- at least one processor configured to execute the set of instructions to:
- calculate a ratio between a first lower limb vertical load of a walker and a second lower limb vertical load of the walker, the first lower limb vertical load measured in a first of two areas into which a sole surface of the walker is divided, the second lower limb vertical load measured in a second of the two areas;
- estimate a floor reaction force based on the ratio and at least either of motion data and lower limb vertical load data of the walker, and outputting the floor reaction force as floor reaction force data;
- and
- calculate a walking state of the walker based on at least either of the motion data and the floor reaction force data, and outputting the walking state.
A walking state measurement method comprising:
- calculating a ratio between a first lower limb vertical load of a walker and a second lower limb vertical load of the walker, the first lower limb vertical load measured in a first of two areas into which a sole surface of the walker is divided, the second lower limb vertical load measured in a second of the two areas;
- estimating a floor reaction force based on the ratio and at least either of motion data and lower limb vertical load data of the walker, and outputting the floor reaction force as floor reaction force data;
- and
- calculating a walking state of the walker based on at least either of the motion data and the floor reaction force data, and outputting the walking state.
A non-transitory computer readable storage medium for storing a walking state measurement program causing a computer to execute processing comprising:
- calculating a ratio between a first lower limb vertical load of a walker and a second lower limb vertical load of the walker, the first lower limb vertical load measured in a first of two areas into which a sole surface of the walker is divided, the second lower limb vertical load measured in a second of the two areas;
- estimating a floor reaction force based on the ratio and at least either of motion data and lower limb vertical load data of the walker, and outputting the floor reaction force as floor reaction force data;
- and
- calculating a walking state of the walker based on at least either of the motion data and the floor reaction force data, and outputting the walking state.
