The Effect of Combined Exercise and NMES on Strength, Proprioception and Reaction Time in Scapholunate Instability

Plain-language summary

In our study, which we conducted to investigate the effect of exercise training combined with neuromuscular electrical stimulation on muscle strength, proprioceptive sensation, reaction time and functionality in patients with scapholunate (SL) instability, individuals with SL instability who meet the inclusion criteria and volunteer to participate in the study will participate. After the approval of the ethics committee, it is planned to include as many individuals with SL instability as the number to be obtained following the power analysis to be performed as a result of the pilot study. The pain of the subjects will be evaluated with the VAS pain scale during rest-activity-exercise. All participants will be evaluated with the isokinetic cybex device for isokinetic muscle strength of the wrist, grip strength with the JAMAR hand held dynometer, NEH evaluation: goniometer, proprioceptive sensation with ACUMAR and isokinetic device, reaction time with blazepod trainer, wrist pain transfer with a digital scale, assessment of upper extremity functional status: pwre (patient rated wrist evaluation), modified mayo wrist score, DASH, EL20 questionnaire, SF-12 questionnaires. In this randomized controlled study, the first group will receive NMES and exercise training 3 days a week for a total of 8 weeks and the other group will receive only exercise training. The evaluations will be done at the beginning and twice in total after the 8-week rehabilitation program. The exercises given to the patients in both groups will be similar for 8 weeks and they will receive a total of 24 sessions of exercise programs with 15 repetitions per day, 3 days a week, accompanied by a physiotherapist. Both groups will also be given home exercises to continue at home. NMES and exercise trainings will be applied in such a way that activation of SL-friendly extensor carpi radialis longus (ECRL), extensor carpi radialis brevis (ECRB), flexor carpi radialis (FCR), and abductor pollicis longus (APL) muscles will be followed by inhibition of non-friendly extensor carpi ulnaris (ECU). After the completion of the thesis, it is planned to add to the literature by examining the effects of exercise training combined with NMES on muscle strength, proprioceptive sensation, reaction time and functionality in individuals diagnosed with SL instability and the superiorities, if any, between the methods.
