2016
We developed a real-time mirror robot system for functional recovery of hemiplegic arms using automatic control technology, conducted a clinical study on healthy subjects, and determined tasks through feedback from rehabilitation doctors. This simple mirror robot can be applied effectively to occupational therapy in stroke patients with a hemiplegic arm.

Muscles that Move the Arm
0 Views •
2024
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles. The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

2025
Self-help support groups are voluntary, community-based organizations that provide a platform for individuals with shared concerns to exchange support, insights, and practical strategies for coping with life challenges. Typically led by group members or paraprofessionals, these groups form a cornerstone of mental health care, especially in reaching populations that are underserved by traditional healthcare systems. Accessibility and Cost-Effectiveness One of the primary strengths of self-help...

Sample preparation for cryo-electron microscopy (cryo-EM) is a significant bottleneck in the structure determination workflow of this method. Here, we provide detailed methods for using an easy-to-use, three-dimensionally printed block for the preparation of support films to stabilize samples for transmission EM studies.
FAQs
Load management occurs through a connected frame, joint, brace, or adjustable surface that carries part of the arm’s weight and directs forces through the support structure. This reduces the amount of effort required from the user’s muscles. Distributing pressure across the body also helps maintain a stable position while limiting concentrated contact forces.
Passive supports rely on their structure and materials to hold or guide the arm without active force generation. Counterbalanced designs offset arm weight through mechanical balancing, while powered versions use actuators to assist movement or positioning. These approaches offer different ways to reduce muscle effort, with the selected mechanism depending on the required level of assistance and control.
Joints help guide or constrain arm movement, while compliant materials can accommodate contact and help distribute pressure. Adjustable surfaces allow the support to be positioned for different arm locations or task requirements. Together, these elements influence stability, motion control, comfort, and positioning precision, making them important when designing supports for varied users and activities.
Performance depends on how effectively the structure transfers load, stabilizes the arm, guides movement, and distributes pressure across the body. The choice between passive support, counterbalancing, compliant materials, or powered actuation also affects muscle assistance and motion control. Adjustable features can further adapt positioning, which is important when tasks require different arm locations or movement patterns.
Integration begins by matching the support mechanism to the intended task, then placing its frame, joint, brace, or surface so it can bear or guide the arm effectively. Engineers may use passive elements, counterbalances, compliant materials, or powered actuators. The resulting arrangement is intended to reduce effort, improve positioning, and control movement within the larger system.
In ergonomic workstations, these supports can reduce arm fatigue and help users maintain more controlled positioning during tasks. In rehabilitation equipment, they can stabilize or guide movement while supporting the user’s arm. Their value lies in combining mechanical assistance with improved positioning, which may support safer task performance and more accessible interaction with equipment.
These systems use arm supports to help manage positioning and movement when users interact with engineered devices. In assistive devices and prosthetics, the support can reduce required muscle effort or provide guidance. During human-robot interaction, controlled support can improve movement precision and help create safer, more accessible task performance around robotic equipment.
