2 Objectives Normal Gait Abnormal Gait Pattern Basic Understanding of Gait Disorder Evaluation & Interventions Basic Understanding of Assistive Devices

3 Definitions Gait Series of rhythmical, alternating movements of trunk & limbs resulting in forward progression of the COG Gait Cycle Begins when reference foot contacts the ground, Ends with subsequent floor contact of the same foot

4 Step length Right step Length = Left step Length (Normal Gait) Stride Length Double the step length Walking base Side-to-side distance between the line of the two feet

5 Comfortable Walking Speed (CWS) Least energy consumption per unit distance Average = 1.4 meter/sec

6 Path of Center of Gravity Center of Gravity (CG): o midway between the hips o Few cm in front of S2 Least energy consumption if CG travels in straight line

7 Path of C.G Vertical displacement: Rhythmic up & down movement Highest point: midstance Lowest point: double support Average displacement: 5cm Path: extremely smooth sinusoidal curve

8 Path of Center of Gravity Overall displacement: Sum of vertical & horizontal displacement Figure ‘8’ movement of CG as seen from AP view Horizontal plane Vertical plane

9 Gait & Aging No clearly accepted standards to define normal Gait in Older Adults Changes at Aging o % reduction in Gait Velocity & Stride Length. o Increase Stance Width. o Increase time spent in the Double Support Phase. o Bent Posture. o Slow & Wide Based Gait. Up to 20% maintain normal Gait pattern into very old age, reinforcing that Aging not inevitably accompanied by disordered Gait.

10 Gait & Balance Disorder Most common causes of falls in Older Adults Evaluation of Gait & Balance disorder parallels the evaluation of FALLS It can lead to o Injury & Disability o loss of independence & reduces level of functioning o limited quality of life o Increase morbidity & mortality 60% yrs, 25% yrs, & 30% 65 yrs have difficulty : o walking 3 blocks or o climbing 1 flight of stairs 20 % require Assistive Devices to ambulate American Geriatrics Society/British Geriatrics Society clinical practice guideline: prevention of falls in older persons Accessed June 3, 2010

11 Falls related statistics 5.8 million US Adults reported Falls o NH Residents (1.6 falls/bed/year) o 10–25% NH falls result in ER visits/hospital care Mostly minor injuries o 10-15% resulting in fracture o 5% in serious soft tissue injury or head trauma Leading cause (75%) of injury deaths for >65 yr o 60% fatal falls happen at home o 30% in public places o 10% in institutions

29 Interventions Modest improvement in Gait & Balance achievable by ASSISTIVE DEVICES. Unfortunately, most cases its unlikely that Gait Disorder are reversible

30 Assistive Devices 6.1 million use assistive devices, 2/3 >65 years of age ASSISTIVE DEVICES IMPROVE: o Balance o Reduce pain o Compensate for weakness or injury o Increase Mobility & Confidence ASSISTIVE DEVICE SELECTION DEPENDS: o Amount of support assistive device offers o Coordination required o Strength, ROM, Balance, Stability, General Condition, & WB restrictions Bateni H, Maki BE. Assistive devices for balance and mobility: benefits, demands, and adverse consequences. Arch Phys Med Rehabil. 2005; 86(1): Faruqui SR, Jaeblon T. Ambulatory assistive devices in orthopaedics: uses and modifications. J Am Acad Orthop Surg. 2010; 18(1):

31 Assistive Device Patients get Assistive Device without recommendations from Medical Professional Evaluation should be done routinely for proper Fit & Use o Cane preferred for balance with one UE o Crutches or a walker appropriate for Both CORRECT HEIGHT & FIT o Correct height of cane/walker At the level of the patient’s wrist crease, as measured with the patient standing upright with arms relaxed at his or her sides, the patient’s elbow naturally flexed at 15 – 30 degree angle

32 Assistive Devices INSTRUCTIONS FOR PROPER USE: o Cane: Should be held contralateral to weak/painful LE & advanced simultaneously with Contralateral Leg. Need upright posture without forward or lateral leaning. Take time when turning & should not lift the device off the ground. o Walker: Both feet should stay between the posterior legs or wheels. Need upright posture without forward or lateral leaning. Take time when turning and should not lift the device off the ground. Kumar R, Roe MC, Scremin OU. Methods for estimating the proper length of a cane. Arch Phys Med Rehabil. 1995; 76(12):

33 Assistive Devices o INSTRUCTIONS FOR PROPER USE Navigating Stairs with Cane/Walker: o Patients with unilateral LE impairment advance the Unimpaired Extremity first when going up stairs AND advance the Impaired Extremity first when going down stairs. o Simply remember this phrase, “Up with the good and down with the bad.” A video about how to use a cane is available online at

34 CANES STANDARD CANE Indications: Mild ataxia (sensory, vestibular, or visual) Mild arthritis Advantages: Inexpensive Adjustable Improves balance Disadvantages: Umbrella handle cause carpal tunnel syndrome Not for weight bearing

35 CANES OFFSET CANE Indication: o Moderate arthritis Advantages: o Inexpensive o Intermittent weight bearing o Shotgun handle put less pressure on palm Disadvantages: o Commonly used incorrectly Liu HH, Eaves J, Wang W, Womack J, Bullock P.
