Physical Activity and Enjoyment in Active Virtual Reality Games in Youth: Comparative Analysis of Gorilla Tag and Beat Saber

Physical Activity and Enjoyment in Active Virtual Reality Games in Youth: Comparative Analysis of Gorilla Tag and Beat Saber

However, data were analyzed for only 4 minutes of playtime, and participants were connected to tubing to measure VO2, which may have restricted movement. To our knowledge, no published studies have evaluated Gorilla Tag in youth or adults.

Home-Based Nonimmersive Virtual Reality Training After Discharge From Inpatient or Outpatient Stroke Rehabilitation: Parallel  Feasibility Randomized Controlled Trial

Home-Based Nonimmersive Virtual Reality Training After Discharge From Inpatient or Outpatient Stroke Rehabilitation: Parallel Feasibility Randomized Controlled Trial

A total of 5 participants had less than 2.0 m of unobstructed space in front of the camera, which led to difficulties with the camera properly tracking the movement of the lower extremities. One TV did not have an accessible HDMI port; an HDMI-to-AV converter was used, resulting in mediocre picture quality. All participants had Wi-Fi in their homes. Most participants managed the use of the computer well, although one participant had difficulties with turning the computer on and off and using a mouse.

A Game-Based Mechatronic Device for Digital Rehabilitation of Hand Function After a Stroke: Design, Prototyping, and Feasibility Study

A Game-Based Mechatronic Device for Digital Rehabilitation of Hand Function After a Stroke: Design, Prototyping, and Feasibility Study

Movement consistency among the 10‐12 game movement responses of the able-bodied adult was similar, as was movement onset time (MOT). Many of the movement trajectories of the patient with stroke were not smooth, exhibited small amplitudes, and demonstrated several target overshoots. It is also evident that the MOT is delayed in the participant with stroke compared to the able-bodied participant.

Detecting Freezing of Gait in Parkinson Disease Using Multiple Wearable Sensors Sets During Various Walking Tasks Relative to Medication Conditions (DetectFoG): Protocol for a Prospective Cohort Study

Detecting Freezing of Gait in Parkinson Disease Using Multiple Wearable Sensors Sets During Various Walking Tasks Relative to Medication Conditions (DetectFoG): Protocol for a Prospective Cohort Study

Patients must self-report as freezers, scoring between 1 and 3 on question 13 of the Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) II [27], and be capable of walking 30 m without assistance to complete the freezing-provoking path.

Effectiveness of a New Device for Hand, Wrist, and Forearm Rehabilitation: Feasibility Randomized Controlled Trial

Effectiveness of a New Device for Hand, Wrist, and Forearm Rehabilitation: Feasibility Randomized Controlled Trial

High movement dosage after distal radius fractures has been found to be critical to increasing grip strength and range of motion. For example, repetitive wrist extension exercises have been found to facilitate regaining grip strength [19]. Additionally, wrist surgical salvage procedures aimed at alleviating osteoarthritis pain have been observed to decrease wrist range of motion and grip strength, potentially leading to long-term impairment [20].

Feasibility of At-Home Hand Arm Bimanual Intensive Training in Virtual Reality: Case Study

Feasibility of At-Home Hand Arm Bimanual Intensive Training in Virtual Reality: Case Study

Finally, remote data monitoring of hand and arm function through 3 D accelerometers in the VR hardware was added to explore the use of actigraphy as a measure of movement characteristics. Actigraphy uses accelerometer-based devices to monitor and quantify physical activity levels and movement patterns over time. By wearing an actigraph device, individuals can track their daily activity levels, including intensity of movement, duration of physical activity, and periods of rest or sedentary behavior.

Implementation and Evaluation of a Gait Training Assistant for the Use of Crutches: Usability Study

Implementation and Evaluation of a Gait Training Assistant for the Use of Crutches: Usability Study

For simplicity, we focused on 3-point gait and forward movement only during this study, as other walking patterns and backward movement work similarly. Training with the gait training assistant. The patient uses the crutches while the Kinect camera in front of him analyzes the crutches as well as the feet. The exercise to be completed is displayed with live feedback on the screen above the camera.

Recognition of Daily Activities in Adults With Wearable Inertial Sensors: Deep Learning Methods Study

Recognition of Daily Activities in Adults With Wearable Inertial Sensors: Deep Learning Methods Study

The functional assessment of ADL is complex, so it is advisable to approach it based on the evaluation of fundamental movement patterns on which these ADL are developed [9-11]. The shoulder and lumbar region are key joint complexes in this regard. Specifically, the shoulder joint is essential in many basic ADL, providing the mobility and stability necessary to perform actions in all planes of movement.

Markerless Motion Capture to Quantify Functional Performance in Neurodegeneration: Systematic Review

Markerless Motion Capture to Quantify Functional Performance in Neurodegeneration: Systematic Review

Importantly, their ability to capture movement unobtrusively is a key benefit for user compliance [8], particularly when working with individuals with cognitive impairments. MMC is attractive for health care and research use, such as monitoring functional performance loss or improvement in neurodegenerative diseases.
