Abstract

Introduction

Neck pain is very common among the patients attending the hospital and in the private practice. Neck pain is seen frequently as a presenting symptom in clinical practice and sometimes compromise the work capacity. Most of the patients are suffering from cervical degenerative diseases. Osteoarthritis is a common rheumatological disease that affects more than 80% of the people aged 55 years and older. ¹ Cervical spondylosis is the results of disc degeneration with associated osteophytosis.² Degeneration in the cervical spine may be associated with pain in the neck but usually only when the degenerative changes are severe.

Mild to moderate cases usually remain asymptomatic. Pain of mechanical disorders is intermittent and increased due to activity. Pain referred to the arm may indicate entrapment of the nerve fiber at the root. Common causes are a prolapsed disc or degenerative changes, including apophyseal joint or ligamentous hypertrophy and osteophytes formation but neurological examination often reveals the level of entrapment.³ Life time prevalence of cervical pain is 67-71% and it can cost 29 billion US dollars in USA.⁴ Khan K et al described that the annu­al prevalence between 15.0% and 50.0% in some studies and middle aged fe­males show much higher frequency of neck pain.⁵ Qayyum S et al also showed that cervical spondylosis is highly prevalent.⁶ Cervical traction with regular physiotherapy modalities like Transcutaneous Electrical Nerve Stimulation (TENS), hot pack and ultrasound accompanied by home exercises for three weeks increased hand grip strength on the affected arm and reduced neck and arm pain substantially in C7 radiculopathy due to herniated disc.⁷

It commonly affects people more than 40 years aged persons and is responsible for varying grades of disability.⁷ Alom et al found the Rheumatology clinic at the department of Physical Medicine, Institute of Post-Graduate Medical and Research (IPGMR) and found that cervical spondylosis was the commonest lesion (23.5%) amongst the various rheumatic disorders.⁸ The use of exercises, aids and appliances, TENS and other electromagnetic applications, are widely used by many specialists.^9,10 Several types of physical therapy and patient education have beneficial effects on musculoskeletal pain.^11-14 Cervical traction is widely used to treat neck disorders. In a study it was found that motorized cervical traction is effective in cervical spondylosis.¹² Rehabilitation treatment like cervical traction along with other measures at home may play an important role to reduce symptoms of the patients with cervical spondylosis. For this purpose, an effort was made to assess the effects of manual continuous home cervical traction on the patients with cervical spondylosis to improve the present situation and to reduce disability and recurrence of symptoms of this type of patients.

Materials and Methods

A randomized clinical trial was conducted during the period of July 2012 to June 2013 to assess the effects of manual continuous home cervical traction on cervical spondylosis. The patients having cervical spondylosis were selected from the outpatient department of Physical Medicine and rehabilitation of Bangabandhu Sheikh Mujib Medical University (BSMMU). They were selected based on the criteria used in the trial of 1966 with some modification, sponsored by the British Association of Physical Medicine.¹⁵

Inclusion criteria: (i) Pain in the neck having a root distribution and being associated with limited and painful movement of the neck; (ii) Pain with full root distribution with paresthesia but without clinical evidence of abnormality; (iii) Chronic pain and stiffness of the neck with or without any root distribution; and (iv) Age more than 30 years or less than 60 years.

Exclusion criteria:(i)Patients with rotator cuff tears, tennis elbow and carpal tunnel syndrome; (ii) Patients with abnormal neurological signs indicating cord compression; (iii) Patients having rheumatoid arthritis, tuberculosis, hepatic & renal disorder or has a bony injury to the cervical spine; and (iv) Patients with acute neck pain.

Before admission into the trial, Institutional Review Board of the BSMMU approval was taken. Informed consent of the patients was taken. History, clinical examination and relevant investigations were done and they were followed weekly for six weeks. About 145 patients were included and were randomly allocated into two groups by the way of lottery. But 20 patients were dropped out.

Group-A (manual continuous home cervical traction group): Here, 61 patients were treated with selective physical modalities that is - exercise, cervical collar, neck support, manual continuous home cervical traction, NSAID, warm moist compression and instruction in posture.

Group-B(conventional treatment receiving group): Here, 64 patients were treated with exercise, shoulder elevation exercise, cervical collar, neck support, warm moist compression, NSAID and instruction in posture.

Cervical traction was given by a manual continuous home cervical traction set in sitting position. The angle of pull was 15^о flexion of the cervical spine. The traction was given continuously for 20 minutes every day at home. The weight of traction in the trial was 15.0% (approx.) of the subject’s body weight. Exercise was given in the form of isometric neck muscle strengthening exercise and shoulder elevation exercise. The exercise was given for 10 repetitions twice daily and posture correction advice was given to all. Posture correction regarding sitting, lying, reading, writing, shaving, chocking bending etc were clearly explained to the patients. A cervical collar was prescribed for all the subjects for posture correction and it was used during activity but not during the time of sleeping. NSAIDs in the form of Naproxen (250 mg) twice daily after meals and omeprazole (20 mg) was given twice daily to prevent drug induced peptic ulcer by NSAIDs to all the patients.

All the patients were assessed initially and weekly for six weeks. Assessment was done by pain score, tenderness index, pain frequency score and visual analogue scale. The results were expressed as percentage, frequencies, mean &plusemn; SD and the level of significant was expressed by p-value unless otherwise stated. Both paired and unpaired Student’s ‘t’ tests were done as required to find out the level of significance.

Results

A total of 125 patients were duly participated in the study. Among them, there were 68 (54.4 %) male and 57 (45.6 %) female (Figure 1). The male female ratio was 1: 0.83. Most of the subjects were married (95.2 %).
N= Total number of patients included in the study. Among them there were 68(54.4 %) male and 57 (45.6 %) female.

Maximum patients were in the middle class (60.8%). The mean age of the subjects was 45.96 ± 11.7 years. The highest number of patients was in the 40- 49 years age group (Figure 2).
N= Total number of patients included in the study. The mean age of the subjects was 45.94 ± 11.65 years. The highest number of patients was in the 40- 49 years age group.

Regarding occupation of the patients, maximum patients of cervical spondylosis were housewife (39.2%) and the table workers were in the second position (20.8%). Baseline clinical characteristics of the patients in both the group were identical (table I).

Treatment response in Group-A (manual continuous home cervical traction group): There was marked improvement of the condition of the patients in response to treatment for 6 weeks. The numerical data of pre-treatment and after treatment assessment scores of this group were compared statistically (paired student's 't'test) and found highly significant (p< 0.007. 95% CI =7.09 to 8.80, table II). So, manual continuous home cervical traction was found significantly effective to reduce the sign and symptoms of cervical spondylosis.

Treatment response in Group-B (conventional treatment receiving group): There was improvement of the patients in response to treatment for 6 weeks. The numerical data of pre-treatment and after- treatment assessment scores of this group were compared statistically (paired student's 't' test) and found highly significant (p< 0.01, 95% CI= 5.21 to 6.81, table III). So, NSAIDs were also found effective to reduce the sign & symptoms of cervical spondylosis.

Overall comparative improvement between two groups: At the time of first visit, there was no significant improvement between two groups (p < 00.36, 95% CI= ‐0.56 to 1.51) but on the other hand there was significant improvement in Group-A than Group-B after six weeks treatment (p < 00.003, 95% CI= ‐2.40 to ‐0.51, table III). This result indicates that the improvement of the patient with cervical spondylosis was seen better in manual continuous home cervical traction group than that of conventional treatment receiving group.

Discussion

In the present study, maximum number of patients was in the 40-49 years age group (30.4%). The mean age was 45.9 ± 11.75 years. British Association of Physical Medicine showed most patients fell in the 40 to 60 years age group, which is also favorable to this study.¹⁵ Irvine et al found almost equal number (223 females and 230 males) of matched male and female patients and found slight preponderance of male over females.¹⁶ This is much nearer to our study. Maximum patients were housewife 49 (39.2 %) and the table workers were in the second position (20.8%) in this study. Bhattacharjee B N et al found that highest number of patients was table worker and housewife was second.¹⁷ This may be due to more awareness development amongst female persons about their health. In the present series, significant improvement was observed in response to manual home cervical traction. The result is in favour of the results presented by the British Association of Physical Medicine.¹⁵ They also found improvement with cervical traction (92.0%). Swezey RL et al found significant improvement with home cervical traction.¹⁸ They used simple, in-expensive over-the-door home cervical traction method of treatment requiring 5 minutes of cervical traction twice daily. They found 81.0% relief of symptoms in cervical spondylosis which supports the findings of our study because we used home cervical traction daily for 15 minutes.

Graham NR supports intermittent traction over continuous traction.¹⁹ Sarfaraj M et al found effectiveness of cervical traction in cervical radiculopathy.²⁰ This supports the results of our study also. Caldwell et al treated 577 patients of cervical syndrome and found 82% good results with constant traction.²¹ This is also favourable to the present study because constant traction was used here.The only effects which traction can be expected to achieve due to distraction between vertebrae at the intervertebral disc and apophyseal joints, tensing the longitudinal ligaments of the spinal column, and slight widening of the intervertebral foramina.²² Shakoor MA et al found that there was significant improvement in response to traction group, where motorized cervical traction was given along with exercise and NSAIDs.²³ Caldwell JW et al applied neck muscle exercises and found good results.²¹ Many studies stated that strength training and some specific exercise was effective moderately to reduce pain and improving function in neck disorders.^24-25 Tanaka S et al found significant relationship of activities of daily living with joint disorders.²⁶ Posture correction was applied here and found insignificant improvement. Zaman A K A et al found home cervical traction significantly reduced symptoms of cervical radiculopathy.²⁷ But Bagheripour B et al found no significant improvement of the patients with cervical spondylosis by over-the-door home cervical traction.²⁸ Actually their sample size was very small and they give 10 session of traction only. Wong LKF et al suggested cervical traction in incline position for better improvement.²⁹

In the present series, traction was given in 15º inclined posture which also a factor for important of our patients. Cervical traction stretches the posterior cervical region and to enlarge the interspaces at the intervertebral foramina. Probably due to this minimal distraction, there were good results in manual continuous home cervical traction which can be applied as necessary basis at home. So, it may reduce the dose of NSAIDs to avoid side effects also.

Conclusion

Manual continuous home cervical traction may be an effective adjunct to reduce symptoms of cervical spondylosis when it is used with conventional treatment. And using manual home cervical traction, daily dose of analgesics can be reduced also.
