Spatio-Temporal Gait Parameters and Gait Symmetry In Diabetic Lower Extremity Burn Injury.
Study Details
Study Description
Brief Summary
This study evaluated the spatio-temporal gait parameters and gait symmetry in individuals with lower extremity burn injury due to diabetic polyneuropathy. Study group consisted of 14 subjects with unilateral lower extremity burn injuries due to diabetic polyneuropathy and control group consisted of 14 subjects with only diabetic polyneuropathy.

Detailed Description
Diabetic polyneuropathy, a frequent complication of diabetes, is used to describe sensory, motor and autonomic nerve damage caused by metabolic and micro vessel alterations due to hyperglycaemia. The signs and symptoms of diabetic polyneuropathy vary according to the type of nerve fiber affected. The involvement of the small nerve fibers results in deterioration of the pain and temperature perception, while the impairing of large nerve fibers result in decrease of touch and proprioception sensations. Due to the sensory loss, accidental foot injuries may develop in patients with diabetic polyneuropathy. While the feet constitute a small percentage (3.5%) of the total body surface area, burn injuries of them in patients with diabetic polyneuropathy can cause significant effects on quality of life because impaired wound healing process in diabetics may cause risk of prolonged bed rest and hospitalization period, and increased early and late complications. Therefore, it has an important effects on daily living activities because it causes inadequacies in gait and balance activities due to the negative effects on mobility and weight bearing functions. In studies that examining changes in gait parameters in other diabetic foot complications such as sensory loss, ulceration, and amputation as secondary to diabetic polyneuropathy have shown that these individuals acquire a protective adaptive gait strategies that allow for more controlled gait in the present of proprioceptive deficits such as slower gait speed, smaller step length and in particular increased opposite foot off time in order to shift body weight from injured limb to unaffected side. There's no studies have yet been conducted to investigating of changes in gait parameters in patients who have diabetic polyneuropathy-related lower extremity burn injury. The aim of this case-control study is to examine whether similar gait strategies have been gained in this group of patients, as indicated in the results of previous studies demonstrating protective adaptive gait strategies that adopt under the presence of other diabetic foot complications due to diabetic polyneuropathy.

Outcome Measures
Primary Outcome Measures
- Step Length [1 week]
It is measured along the length of the walkway, from the heel center of the current footprint to the heel center of the previous footprint on the opposite foot.The unit of measure is centimeters.
Secondary Outcome Measures
- Stride Length [1 week]
It is measured on the line of progression between the heel points of two consecutive footprints of the same foot (left to left, right to right). The unit of measure is centimeters.
- Step Width [1 week]
It is measured from the midline midpoint of the current footprint to the midline midpoint of the previous footprint on the opposite foot.The unit of measure is centimeters.
- Foot Progression Angle [1 week]
It is the angle between the line of progression and the midline of the footprint. This angle is zero if the geometric mid- line of the footprint is parallel to the line of progression; positive, toe-out, when the mid-line of the footprint is outside the line of progression and negative, toe-in, when inside the line of progression. The unit of measure is degrees.
- Speed [1 week]
It is obtained after dividing the distance traveled by the ambulation time. It is expressed in centimeters per second (cm/sec)
- Cadence [1 week]
The rate at which a person walk, expressed in steps per minute (step/min). The average cadence is 100 - 115 steps/min.
- Percentage of Double Support [1 week]
It is the amount of time that a person spends with both feet on the ground during one gait cycle. It is presented as a percentage of the gait cycle time (% gait cycle). The percentage of time spent in double support decreases as the speed of walking increases.
- Percentage of Stance [1 week]
The stance phase is the weight bearing portion of each gait cycle. It is initiated by heel contact and ends with toe off of the same foot. It is the time elapsed between the first contact and the last contact of two consecutive footfalls on the same foot. It is also presented as a percentage of the gait cycle time (% gait cycle)
- Percentage of Swing [1 week]
It is initiated with toe off and ends with heel strike. It is the time elapsed between the last contact of the current footfall to the first contact of the next footfall on the same foot. It is expressed in seconds (sec) and it is also presented as a percent of the gait cycle (% gait cycle) of the same foot. The Swing Time is equal to the Single Support time of the opposite foot.
- Symmetry Index [1 week]
It's calculated in order to evaluate symmetry and bilateral coordination of gait. The Symmetry Index and Symmetry Angle are interpreted as a complete symmetry if the result is 0. Evaluation of asymmetries observed in the spatio-temporal characteristics, a deviation of at least 10% from the 0 value for exact symmetry.
