Upper-extremity position sense testing in people with cervical nerve root compression

Assessment of Upper Extremity Proprioception in Patients With Cervical Radiculopathy

Marmara University · NCT07319156

This project will test whether adults with cervical radiculopathy have poorer upper-arm position sense than healthy adults.

What this trial studies

This is an observational, case-control comparison of adults aged 18–65 who have cervical radiculopathy confirmed by clinical exam and cervical MRI versus healthy control participants. Participants will undergo multi-joint, multi-planar proprioception testing using the PRO-Reach method alongside routine clinical sensory and motor examinations. The study excludes conditions that independently impair proprioception (for example diabetes, polyneuropathy, recent cervical or upper-extremity surgery, entrapment neuropathies, or recent cervical physical therapy). The investigators will compare proprioceptive performance between groups and examine how proprioception relates to clinical measures such as pain distribution, strength, reflexes, and functional outcomes.

Who should consider this trial

Good fit: Adults aged 18–65 with radicular arm pain and cervical MRI evidence of disc herniation corresponding to their symptoms who are willing to attend in-person testing are ideal candidates.

Not a fit: People with conditions that independently impair sensation or motor control (for example diabetes, polyneuropathy, entrapment neuropathies), recent cervical or arm surgery, pregnancy, or major psychiatric or intellectual disability are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the findings could help clinicians identify proprioceptive loss linked to cervical radiculopathy and guide more targeted sensorimotor rehabilitation.

How similar studies have performed: Previous work has documented proprioceptive deficits in broader neck-pain and cervical spondylosis populations, but direct data on cervical disc-related radiculopathy are limited and PRO-Reach is a relatively new, not yet widely validated approach.
