Summary
This review highlights methods for measuring pistoning in lower limb prostheses. Further research is needed to establish standardized, accurate techniques for evaluating this key suspension system indicator.
Area of Science:
- Prosthetics and Orthotics
- Biomechanical Engineering
- Rehabilitation Science
Background:
- Vertical displacement, or pistoning, is a critical indicator of lower limb prosthesis suspension system efficiency.
- Reducing pistoning and developing effective evaluation methods can significantly aid amputee rehabilitation.
Purpose of the Study:
- To systematically review existing research on pistoning in lower limb prostheses.
- To analyze various techniques used to measure pistoning in static and dynamic conditions.
Main Methods:
- A comprehensive literature review was conducted.
- Searches utilized keywords such as 'pistoning,' 'suspension,' and 'lower limb prosthetics' across major scientific databases.
- Sixteen relevant articles were selected for in-depth analysis.
Main Results:
- Various methods for measuring pistoning were identified, including radiological techniques, photographic methods, motion analysis, and sensor-based systems.
- Pistoning has been quantified in both static (standing) and dynamic (walking) states.
Conclusions:
- There is a need for the development and validation of simple, accurate, and safe methods for measuring pistoning.
- Future research should aim to establish a gold standard for acceptable pistoning ranges within prosthetic sockets.

01:14Prevention of Further Absorption of Poison
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...
01:23Peripheral Artery Disease V: Postoperative Nursing Management
During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
01:26Peripheral Artery Disease IV: Nursing Management
The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses, temperature changes,...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:27Assessment of the Cardiovascular System III: Palpation
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

01:26Pharmaceutical Poisoning: Treatment Strategies
Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...
