The implementation of this prototype consists of four different adaptations, for each movement, a sensors interface electronic board, a control board, and a graphical user interface where the physiotherapist is able to set up a personalized rehabilitation cycle according to the patient needs.
We have done field tests of the prototype with a patient with elbow and wrist fracture diagnosis, as we observe a improve in mobility of the both joints through a small number of rehabilitation session, as regards is concluded that the prototype allows to reach progressively angles nearer to angular limits of pronation and supination of elbow movements and flexion –extension of wrist, with a reduction of 50% of number of sessions by conventional methods.

I. INTRODUCTION
The goal of rehabilitation is to achieve the
The foundational concept of the biomechanical approach has its roots in the structural arrangement of the human body. It also places emphasis on the functional components of the body system. An occupational therapist analyzes physical demands of expected performances when analyzing activities. The practitioner matches the client’s body function and body structure to physical activity demands before proposing treatment.
Thus obtaining on proposed rehabilitation program in accordance with the scientific foundations in order to achieve the desired benefit which represents in enhancing the functional efficiency of athletes after ACL surgery for return to their preinjury state and participate in their sports activities.
1. To bring equipments to use with 2 patients in Watpunpee community. The first one had multiple problems of the paralysis of arm and leg, right hand and fingers could not loosen and the left leg was bent. The second patient has the paralysis of right arm and leg, the right side shoulder falls, crinkled fingers, and 2 both of ankles fall. To give the patient stretch a leg and exercise at hand and the shoulder joint with the invention. To exercise leg by the patient lie down and to help the patient exercise their legs, until they can sit when do exercise. The patients have muscle and joint of arm and leg improve.
First, goniometry will be used to measure the range of motion (ROM) of the client’s left hand to compare it to the normal range of values. Also, the volumeter will be used to determine amount of chronic swelling on his left hand compared to his right hand. Also, the pinch meter will be used to determine his pinch strength in various pinch positions in the client’s left hand compared to his right hand. As well, a pain assessment, specifically the Visual Analog Scale, will be used to determine the realistic extent of pain the client presents with in his left hand. Also, the dynamometer will be used to determine grip strength in left hand compared to
This article takes a perspective of the patient approach, in how ultimately long term their health in their hands. How the physical therapists are there to guide and make small corrections,
The information in this literature review was collected from an expert interview and the search databases Science Direct, PubMed, and Google Scholar. The expert for the expert interview was selected based on experience with designing prosthetics for individuals that had lost their hand and potentially part of their arm (Birdwell, 2016). The databases were searched using keywords “spinal cord injury”, “hand movement”, and “fine motor movement”. In PubMed the selection was also narrowed down by selecting only studies done on humans. New terminology was searched through science direct due to the built in function that allows for key words from the article to be selected for further information from multiple books or journals.
Occupational Therapy is a growing field; one that is constantly changing as technology becomes more advanced. There are different techniques and methods used in this field, as well as the field of physical therapy, in order assist in client advancement and growth. The traditional method being discussed is Proprioceptive Neuromuscular Facilitation also known as PNF and the contemporary technique is Kinesio Taping. These techniques and methods came about for the same purpose, and that is to ultimately help both the Practitioners and of course clients they work with.
Passive stretch was performed to client’s right ( R) UE while she was side lying on the mat to increase ROM in order for the client to use her ( R) hand as a stabilizer during fine motor coordination activities. OTS performed 10 reps of scapular elevation, depression, protraction and retraction, shoulder flexion, elbow flexion, wrist flexion, and thumb interphalangeal (IP) flexion, extension, abduction, adduction and finger 2-5 distal interphalangeal (DIP) and proximal interphalangeal (PIP) flexion, extension,
I have been fortunate enough to observe my coach perform various techniques to restore mobility and motion. One such technique that I was able to survey was the rehabilitation of an anterior shoulder dislocation. During the acute phase of therapy, isometric exercises were used to strengthen the rotator cuff muscles. The next phase was to achieve full range of motion without pain and continue to strengthen the muscles. This was done through abduction and external rotation, wall climbs/slides, and pulley’s.
Exoskeletons and orthoses are defined as mechanical devices “worn” by an operator and fitted closely to the body to work in concert with the operator’s movements. The term “exoskeleton” is used to describe a device that augments the wearers performance, while the term “orthosis” is used to describe a device used to assist a person with limb pathology. Lower extremity exoskeletons seek to circumvent the limitations of autonomous legged robots by adding a human operator to the system. The system is designed in parallel with human limbs to augment human strength and endurance during locomotion. The basic system design consists of two powered anthropomorphic legs, a power unit, associated actuators, sensors, and a control unit.
A study conducted by Toshiki Kobayashi, Madeline L. Singer, Michael S. Orendurff, Fan Gao, Wayne K. Daly, and K. Bo Foreman and published in the journal of Clinical Biomechanics aimed to describe the relationship between the plantarflexion resistive moment of an articulated ankle–foot orthosis (AFO), a piece of corrective footwear, and the angles and moments of the ankle and knee while walking, in order to better aid patients post stroke. The major driving force of the study is that many patients who have suffered a stroke have resulting difficulties with mobility due to changes in their gait and muscle strength. This study suggests that there can possibly be a better designed and more personalized AFO to decrease unpleasant side effects of AFO use, such as pain and limited mobility.
A torn ACL will not be able to heal on its on however, there are non-surgical options to help ease the injury. A concise and careful rehabilitation program will help aid the physical recovery of an ACL tear, easing the pain and growing the supporting muscles. Non-surgical treatment is only ever seen in elderly patients, with little to no activity levels. An MRI scan is often implicated to try and discover additional injuries that often occur with a torn ACL, which may change the way in which the surgery is conducted (Sutter Health, 2016). Surgical treatments often see the use of a graft, usually taken from the patient’s leg, particularly from either the hamstring or patella tendon (Wallace, B 2017). The graft acts as scaffolding for the new
The aging process and/or osteoarthritis contribute to decreased hand function; hand function disability causes a decrease in one or more activities of daily living. Jar and bottle opening is one of the most difficult activities of daily living for the elderly population. Studies with elderly adults have been performed, but no studies have included the elderly with known hand limitations. Occupational therapists use mostly a biomedical and adaptive equipment approach in the elderly with hand osteoarthritis, which is not a balanced plan of care that is client-centered and occupation-based. Studies show the elderly populations do not always utilize the adaptive equipment over time. The desire is to use a “hands-on approach” in fabricating one’s own adaptive equipment in occupational therapy treatment; the belief is this would improve acceptance and compliance by the user, and also enhance the adaptive skills of the client with changing hand function. The
