Comparison of Robot Assisted Gait Training and Body Weight Supported Treadmill Training Using Gait Analysis and SEMG Measurements

Kinematic parameters: Hip joint flexion range of motion degree in the swing phase in the sagittal plane, knee joint maximum flexion angle degree, ankle joint dorsiflexion range of motion degree

The average EMG (AEMG) amplitude and co-contraction indices (CCI) are calculated for the affected lower extremity's knee flexion and ankle dorsiflexion during the swing phase. CCI is calculated using the formula antagonistic muscle AEMG / (antagonistic muscle AEMG + agonistic muscle AEMG)

The researchers examined the effects such as walking line length, single support line, forward and backward rollers and lateral symmetry indexes in the pressure analyses. In the gait analysis, walking speed, cadence, step length, step width, foot rotation angle, step duration, double support duration, stance phase, swing phase, single support phase, pre-swing phase, mid-swing phase, terminal swing phase, stance duration, swing duration, double phase, double step length and temporal symmetry index were evaluated. The temporal symmetry index was calculated using the following formula: Swing duration of the affected side of the patient / Swing duration of the unaffected side of the patient

The Functional Ambulation Scale (FAS) is a scale used to assess the level of ambulation in patients. It is divided into six categories graded from 0 to 5: FAS 0: no ambulation, FAS 1-2: unable to walk without assistance, FAS 3-5: able to walk 6 meters independently.

For lower extremity, the Fugl-Meyer Assessment (FMA-LE) was used in our study, consisting of a total of 17 items with a maximum score of 34 points. The scale assesses reflexes, synergy-dependent or synergy-independent voluntary movements, coordination, and speed. Each item is scored between 0 and 2 points, with a higher score indicating better outcomes.

In the 6-minute walk test (6MWT), researchers asked participants to walk down a 30-meter hospital hallway at their own pace for 6 minutes, following standard instructions to cover as much distance as possible. The distance walked was recorded in meters.
