Outcome of Physiotherapy After Surgery for Cervical Disc Disease: a Prospective Multi-Centre Trial

Not Applicable

Completed

• Conditions: Radiculopathy
• Interventions: Other: Structured behavioural medicine program; Other: Customary treatment

• Registration Number: NCT01547611
• Lead Sponsor: Linkoeping University

Brief Summary

Many patients with cervical disc disease have long-lasting and complex symptoms with chronic pain, low levels of physical and psychological function and sick-leave. Surgery on a few segmental levels might be expected to solve the disc-specific pain but not the non-specific neck pain and the patients'illness. As much as 2/3 of the patients have been reported to have remaining physical/ psychological disability long-term after surgery. A structured physiotherapy programme after surgery may improve patients'function and return to work. The main purpose of the study is to evaluate what a well structured rehabilitation program adds to the customary treatment after surgery for radiculopathy due to cervical disc disease in respect to function, disability, workability and cost effectiveness. The study is a prospective randomised controlled multi-centre study, with an independent and blinded investigator comparing two alternatives of rehabilitation. 200 patients in working age, with cervical disc disease with clinical findings and symptoms of cervical nerve root compression will be included after informed consent. After inclusion in the study patients will be randomised to one out of the two alternatives of physiotherapy, (A) customary treatment (information/ advice on the specialist clinic) or (A+B) active physiotherapy; standardised and structured program of neck specific exercises combined with a behavioural approach plus customary treatment. Patients will be evaluated both clinically and with questionnaires before surgery, 6 weeks, 3 months, 6 months, 12 months and 24 months after surgery. Main outcome variable are neck specific disability. Cost-effectiveness will be calculated. The inclusion will preliminary be closed 2012. The study could contribute to a better clinical decision making, a better health care which will reduce physical, mental and social costs for the patients, and improve the rates of patients returning to and staying at work.

• Status: COMPLETED
• Sex: All
• Target Recruitment: 202

Inclusion Criteria

• Patients will be included from four Neurosurgical clinics in the south of Sweden and the rehabilitation will be performed in primary care units in several counties.
• Patients in working age, with MRI-verified cervical disc disease with clinical findings and symptoms of cervical nerve root compression and who have had surgery with anterior decompression and fusion or posterior surgery (foraminotomy/ laminectomy) will be included after informed consent.

Exclusion Criteria

Arm && Interventions

Group	Intervention	Description
structured behavioural medicine program	Structured behavioural medicine program	Group B (extended physiotherapy treatment), customary treatment (please see above) plus a standardised and structured behavioural medicine program. The behavioural medicine program includes functional behavioural analysis of the problem, medical exercise therapy, strategies to increase self-efficacy in activities and problem-solving strategies for coping with disability.
Customary treatment	Customary treatment	Group A (physiotherapy as usual), customary treatment. The staff at the Neurosurgical clinic will give the patient ordinary pre- and postoperative information. The physiotherapist at the Neurosurgical clinic informs the patients what to avoid the first weeks after surgery and the importance of a good posture and ergonomic thinking in daily life. The patient is also instructed how to do exercises for the shoulder range of motion. Patients have ordinary post-surgery visit to the surgeon and to the physiotherapist about 6 weeks after the surgery, where physiotherapist instructs the patient in exercises for active neck range of motion.

Primary Outcome Measures

Name	Time	Method
Neck Disability Index (NDI)	Baseline and change after 3, 6, 12 and 24 months follow-up. The outcome measures is going to report a change over time.	NDI will be measured at baseline before surgical intervention. Change from baseline in NDI will be measured at 3, 6, 12 and 24 months follow-up.; NDI will be used to investigate Neck specific disability. The 10 sections in the questionnaire are rated on a six-point scale (0-5 point). The scores for all sections are added together and transformed to percentages (where 0% is no pain or difficulties and 100% is highest score for pain and difficulty on all items.

Secondary Outcome Measures

Name	Time	Method
Pain intensity on visual analogue scale (VAS 0-100mm)	The outcome measure is going to report a change over time from baseline and at 6 weeks, 3, 6, 12 and 24 months follow-up	Pain intensity of neck pain, arm pain and headache, respectively
Dizziness/ unsteadiness measured on a visual analogue scale (VAS) 0-100mm	The outcome measure is going to report a change over time from baseline to 3, 6, 12 and 24 months follow-up	Dizziness/ unsteadiness measured on a VAS-scale (0=no problems, 100= pretty severe problems).
Modified Odom scale and a question if how important the change is.	The outcome measure is going to report a change over time from before surgery to 6 weeks, 3, 6, 12 and 24 months follow-up.	A 1 to 6 point scale of treatment outcome. 1=recovered, 2=much better, 3=better, 4=unchanged, 5=worse, 6= much worse. How important is the change on a 0 to 10 point horizontal scale (0=not at all important, 10= very important).
