Examining the Hand in the Video Consultation

Abstract

Background Video consultations could support patient care in hand surgery during social distancing in the COVID-19 era. According to the literature, images of hand and fingers can support telediagnosis in hand emergencies. We present this feasibility study on online video consultation in hand surgery. Methods A structured examination was designed to query the medical history and examine motor skills, sensitivity, strength and function tests of the hand. Thirty examinations on both hands were carried out by online video consultation, then in direct contact and compared with each other. Results With 4560 evaluated range of movement of the hand and finger joints, there was a high correlation between the measurement methods of R\u2009=\u20090.995 (p\u2009<\u20090.0001, confidence interval 0.9946\u200a–\u200a0.9954). In the video-based examination, 84.6% of the measured values showed a deviation of less than 5° compared to the direct examination, 92.8% less than 10° deviation. Good accordance was also found in the patientʼs medical history. An estimating examination of sensitivity, function and strength during video examination is feasible with simple auxiliary aids. Deficits are evident in the detection of scars, in function tests and the absence of haptic findings. Conclusion Online video consultation allows hand examination with sufficient documentation of hand and finger movements (range of motion) and proper evaluation of symptoms. It cannot replace direct examination but complement patient care in hand surgery even beyond the current COVID-19 pandemic.
