Résumé
Gait is an autonomic process consisting of coordinated movements of the upper extremities, lower extremities, trunk and pelvis. However, researches regarding effects of upper extremity problems on gait parameters are limited. The aim of this study was to investigate the effects of arm swing on spatiotemporal characteristics of gait in individuals with unilateral transhumeral amputations. A total of 25 unilateral transhumeral amputees and 25 healthy subjects were included. Information on the demographic features of individuals, amputations, and prosthetic devices were recorded. Spatiotemporal characteristics of gait were obtained using the GAITRite electronic walkway, and the arm swing was evaluated with the two video-cameras and analyzed using the Dartfish Pro Suite 7 software. The groups were similar regarding their age, height and weight. Mean duration from the amputation was 14.91 ± 10.90 years, and the mean weight of the prostheses was 1.44 ± 0.39 kg. Amputees had a less ambulatory arm swing on their amputated sides compared to their intact arms and healthy individuals. When the amputee group was compared to the healthy individuals, their step and stride lengths were shorter and their foot progression angle was higher, their gait velocity and cadence were lower than the healthy group. The reduction of arm swing on the amputated side in unilateral transhumeral amputees is thought to be due to (1) use of the contralateral side in functional activities, (2) restriction of shoulder joint movement of socket boundaries and (3) fixed mechanical elbow joint. It has been thought that a decrease in the arm swing during walking may lead to a decrease in step length, stride length, and gait velocity.

BACKGROUND
Gait is an autonomic process consisting of coordinated movements of the upper extremities, lower extremities, trunk and pelvis. However, researches regarding effects of upper extremity problems on gait parameters are limited.
RESEARCH QUESTION
The aim of this study was to investigate the effects of arm swing on spatiotemporal characteristics of gait in individuals with unilateral transhumeral amputations.
METHODS
A total of 25 unilateral transhumeral amputees and 25 healthy subjects were included. Information on the demographic features of individuals, amputations, and prosthetic devices were recorded. Spatiotemporal characteristics of gait were obtained using the GAITRite electronic walkway, and the arm swing was evaluated with the two video-cameras and analyzed using the Dartfish Pro Suite 7 software.
RESULTS
The groups were similar regarding their age, height and weight. Mean duration from the amputation was 14.91 ± 10.90 years, and the mean weight of the prostheses was 1.44 ± 0.39 kg. Amputees had a less ambulatory arm swing on their amputated sides compared to their intact arms and healthy individuals. When the amputee group was compared to the healthy individuals, their step and stride lengths were shorter and their foot progression angle was higher, their gait velocity and cadence were lower than the healthy group.
SIGNIFICANCE
The reduction of arm swing on the amputated side in unilateral transhumeral amputees is thought to be due to (1) use of the contralateral side in functional activities, (2) restriction of shoulder joint movement of socket boundaries and (3) fixed mechanical elbow joint. It has been thought that a decrease in the arm swing during walking may lead to a decrease in step length, stride length, and gait velocity.
