Background: the current methods of assessing motor function rely primarily on the clinician's judgment of the patient's physical examination and the patient's self-administered surveys. recently,computerized handgrip tools have been designed as an objective method to quantify upper-extremity motor function. this pilot study explores the use of the medisens handgrip as a potential clinical tool for objectively assessing the motor function of the hand.methods. eleven patients with cervical spondylotic myelopathy (csm) were followed for three months. eighteen age-matched healthy participants were followed for two months. the neuromotor function and the patient-perceived motor function of these patients were assessed with the medisens device and the oswestry disability index respectively. the medisens device utilized a target tracking test to investigate the neuromotor capacity of the participants. the mean absolute error (mae) between the target curve and the curve tracing achieved by the participants was used as the assessment metric. the patients' adjusted medisens mae scores were then compared to the controls. the csm patients were further classified as either functional or nonfunctional in order to validate the system's responsiveness. finally,the correlation between the medisens mae score and the odi score was investigated.results: the control participants had lower medisens mae scores of 8.09%±1.60%,while the cervical spinal disorder patients had greater medisens mae scores of 11.24%±6.29%. following surgery,the functional csm patients had an average medisens mae score of 7.13%±1.60%,while the nonfunctional csm patients had an average score of 12.41%±6.32%. the medisens mae and the odi scores showed a statistically significant correlation (r=-0.341,p<1.14×10-5). a bland-altman plot was then used to validate the agreement between the two scores. furthermore,the percentage improvement of the the two scores after receiving the surgical intervention showed a significant correlation (r=-0.723,p<0.04).conclusions: the medisens handgrip device is capable of identifying patients with impaired motor function of the hand. the medisens handgrip scores correlate with the odi scores and may serve as an objective alternative for assessing motor function of the hand. © 2014 getachew et al.; licensee biomed central ltd.
