Spatial and temporal variables of gait

  1. 1. SPATIAL AND TEMPORAL VARIABLES OF GAIT NITHIN NAIR MPT - 1 (2017-18) COMMUNITY PHYSIOTHERAPY
  2. 2. LEARNING OBJECTIVES AFTERTHIS SESSION STUDENTS WILL BE ABLETO, Enlist Temporal and Spatial variables of gait Enumerate each variables of gait briefly
  3. 3. VARIABLES OF GAIT SPATIAL VARIABLES SINGLE LEG STANCE DOUBLE LEG STANCE STEP LENGTH STRIDE LENGTH BASE (STEP) WIDTH DEGREE OF TOE OUT TEMPORAL VARIABLES SINGLE SUPPORT TIME DOUBLE SUPPORT TIME STEP TIME STRIDE TIME CADENCE GAIT SPEED
  4. 4. VARIABLES OF GAIT BASE WIDTH : DISTANCE BETWEEN THE TWO FEET CALCULATED – LINEAR DISTANCE BETWEEN THE MIDPOINT OF HEELS OF BOTH THE FEET NORMAL RANGE: 5 – 10 cm (2 to 4 inches)
  5. 5. VARIABLES OF GAIT SINGLE LEG STANCE + SINGLE SUPPORT TIME OCCURS WHEN ONLY ONE LEG IS ON THE GROUND OCCURS TWICE IN GAIT CYCLE (40%) AMOUNT OF TIME THAT ELAPSES WHEN ONLY ONE EXTREMITY IS ON THE SUPPORTING SURFACE
  6. 6. VARIABLES OF GAIT DOUBLE LEG STANCE + DOUBLE SUPPORT TIME OCCURS WHEN BOTH THE FEET ARE ON THE GROUND OCCURS TWICE IN GAIT CYCLE (20%) AMOUNT OF TIME SPENT WITH BOTH THE FEET ON THE GROUND
  7. 7. VARIABLES OF GAIT STEP LENGTH + STEP TIME LINEAR DISTANCE BETWEEN TWO SUCCESSIVE POINTS SUCCESSIVE POINTS OF CONTACT OF OPPOSITE OPPOSITE EXTREMITIES HEEL STRIKE (ONE EXTREMITY) – HEEL STRIKE (OTHER EXTREMITY) AVERAGE: 72 cm (28 inches) AMOUNT OF TIME SPENT DURING SINGLE STEP STEP MEASURED: SECONDS/STEP
  8. 8. VARIABLES OF GAIT STRIDE LENGTH + STRIDE TIME LINEAR DISTANCE BETWEEN TWO SUCCESSIVE EVENTS OF SAME LOWER EXTREMITY HEEL STRIKE (ONE EXTREMITY) – HEEL EXTREMITY) AVERAGE: 144 cm (56 inches) AMOUNT OF TIME TAKEN TO ACCOMPLISH ONE STRIDE (FULL GAIT CYCLE)
  9. 9. VARIABLES OF GAIT CADENCE + GAIT SPEED NUMBER OF STEPS PER MINUTE AVERAGE : 90 – 120 steps / minute DISTANCE COVERED IN A GIVEN AMOUNT OF TIME AVERAGE: 1.4 m / sec or 3 mph
  10. 10. VARIABLES OF GAIT DEGREE OF TOE OUT IT REPRESENTS ANGLE OF FOOT PLACEMENT MEASUREMENT – ANGLE FORMED BY EACH FOOT’S LINE OF LINE INTERSECTING THE CENTER OF HEEL AND THE SECOND TOE MEN - 7°
