Isokinetic Parameters and the Amputee Mobility Predictor Scale

Are There Any Relationship Between Isokinetic Parameters and the Amputee Mobility Predictor Scale?

There is very limited research examining isokinetic parameters and activity level in patients with amputation.. Therefore, the aims of this study were to illustrate isokinetic measurements including strength and proprioception and to analyze the correlation between those isokinetic parameters and activity level and to predict amputee mobility score. It is hypothesized that muscle strength and proprioception were associated with activity level and could be used to estimate amputee mobility scale score in patients with amputation.

Study Overview

• Status: Completed
• Conditions: Amputation, Traumatic
• Intervention / Treatment: Diagnostic test: İsokinetic assessment

Detailed Description

Isokinetic measurements are used in the rehabilitation of amputee patients and to evaluate the effectiveness of rehabilitation. The parameters that are frequently looked at in these measurements are isokinetic muscle strength and proprioception.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Amputee patients; age between 18-65 years, (b) time after amputation ≥ 6 months, (c) unilateral or bilateral amputation above the ankle level	Diagnostic test: İsokinetic assessment; Isokinetic assessments of hip flexor and extensor muscle strength and proprioception wiill be performed

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Isokinetic muscle strength	Muscle strength will be assessed for flexion and extension of the hip using a computer-assisted isokinetic system (CYBEX) in the isokinetic performance laboratory	Through study completion, an average of 1 month
Isokinetic proprioception	Isokinetic proprioception will be measured with the CYBEX device. The hip joint is chosen because the most proximal level amputation will be the above-knee level	Through study completion, an average of 1 month
Amputee mobility predictor	Amputee mobility predictor (AMP) is one of the performance-based outcome measures commonly used prior to prosthetic fitting and predict function following prosthetic prescription.The AMP is a 21-item tool for predicting the level of ambulation by assessing static and dynamic balance, transfers, and gait. With this scale, unilateral patients can be evaluated with or without prosthesis. However, activity level of bilateral amputees can only be predicted if they have prostheses. In this study, AMP evaluation of all patients will be performed by a physiotherapist with 10 years of experience in amputee rehabilitation, blinded to other clinical information.	Through study completion, an average of 1 month
