CONCURRENT VALIDITY OF THE CONTINUOUS SCALE-PHYSICAL FUNCTIONAL PEFORMANCE-10 (CS-PFP-10) TEST IN TRANSFEMORAL AMPUTEES.

The Continuous Scale-Physical Functional Performance-10 (CS-PFP-10) test consists of 10 standardized daily living tasks that evaluate overall physical functional performance and performance in five individual functional domains: upper body strength (UBS), upper body flexibility (UBF), lower body strength (LBS), balance and coordination (BAL), and endurance (END). This study sought to determine the concurrent validity of the CS-PFP-10 test and its functional domains that involve the lower extremities (LBS, BAL, or END) in comparison to measures that have established validity for use in persons with transfemoral amputation (TFA). Ten TFA patients functioning at K3 or higher (Medicare Functional Classification Level) completed the study.

Functional performance differences between the Genium and C-Leg prosthetic knees and intact knees.

Microprocessor prosthetic knees (MPKs) have advanced technologically, offering new features to decrease impairment and activity limitations for persons with transfemoral amputation (TFA). The Genium knee is functionally untested, and functional differences between it and intact knees are unknown. This study sought to determine whether Genium use improves functional performance compared with the C-Leg.

Golf hand prosthesis performance of transradial amputees.

Background: Typical upper limb prostheses may limit sports participation; therefore, specialized terminal devices are often needed. The purpose of this study was to evaluate the ability of transradial amputees to play golf using a specialized terminal device.

Case Description And Methods: Club head speed, X-factor, and elbow motion of two individuals with transradial amputations using an Eagle Golf terminal device were compared to a non-amputee during a golf swing.

Human motion intention based scaled teleoperation for orientation assistance in preshaping for grasping.

In this paper, we present an algorithm that provides human motion intention based assistance to users teleoperating a remote gripper for preshaping over an object in order to grasp it. Human motion data from the remote arm is used to train a Hidden Markov Model (HMM) offline. During the execution of a grasping task, the motion data is processed in real time through the HMM to determine the intended preshape configuration of the user.

Study of variation in human upper body parameters and motion for use in robotics based simulation.

This paper reviews the variations in human upper body motion of subjects completing activities of daily living. This study was completed to serve as a reference to evaluate the quality of simulated of human motion. In this paper we define the variation in motion as the variation in subjects' parameters (link lengths), joint angles, and hand positions, for a given task.

Kinetic asymmetry in transfemoral amputees while performing sit to stand and stand to sit movements.

Transitional movements are a determinant of functional independence and have limited study in amputees. Microprocessor prosthetic knees' abilities to assist transfemoral amputees with sitting and standing have not been studied. Through cross-sectional study, 21 transfemoral amputees, divided into 3 groups of 7 by knee type (power knee, C-leg, Mauch SNS) and 7 non-amputee controls (n=28) performed sit to stand and stand to sit while kinematic and kinetic data were recorded.

Kinematic comparison of myoelectric and body powered prostheses while performing common activities.

This study examined the kinematic differences of a bilateral transradial amputee using myoelectric and body-powered prostheses during select activities of daily living. First in harness suspended, body powered then self-suspended externally powered prostheses, the subject's shoulder and elbow joint movements were calculated and compared while completing an elbow range of motion test, simulated drinking from an empty cup, and opening a door. In this case, body-powered prostheses allowed for greater range of elbow flexion but required more shoulder flexion to complete the tasks that required continuous grasp.

Compensatory movements of transradial prosthesis users during common tasks.

Background: Recent studies have documented motions of the upper limbs of healthy subjects during activities of daily living. The aim of this study was to investigate compensatory motions of the upper extremity and torso during tasks for transradial prosthesis users and to determine if bracing simulates prosthesis use.

Methods: Seven transradial myoelectric prosthesis users and 10 non-amputee volunteers performed four common tasks.
