Background: Headache is common in the elderly. Cervical degenerative changes are universal with ageing and cervicogenic headache is proposed (albeit without evidence) as a frequent cause of headache in this age group. Previous research identified a pattern of cervical musculoskeletal impairment which differentiated cervicogenic headache from other frequent headaches but this study was undertaken on younger/middle aged individuals. The value of this diagnostic pattern could be questioned for an older population with concomitant age related changes in the musculoskeletal system. The first and foremost aim of this research was to determine if cervical musculoskeletal impairment was specific to headaches classifiable as cervicogenic or was more generic to headache in elders. Participants with headache were sub-grouped on the basis of the pattern of cervical musculoskeletal impairment and the relationship between this grouping and headache classification was investigated. The presence of sensory hypersensitivity and psychological distress are features of headache that can provide information on the underlying mechanisms and provide management directives for headache. There is little knowledge of whether or not these features are influenced by a factor of age. Thus the second and third aims of this research were to investigate sensory features and psychological and quality of life features in the elderly with headache. Methods: One hundred and eighteen subjects, aged 60 to 75 years with recurrent headache and 44 controls were studied. Ninety-three reported a single headache and 25, two or more headache types. All subjects completed the Neck Disability Index (NDI), Geriatric Depression Scale-short form (GDS-S) and SF-36 questionnaires. Subjects with headache also completed a headache questionnaire and the Survey of Pain Attitudes (SOPA-35). Neck function measures included range of motion, manual examination of cervical segments, cranio-cervical flexor muscle function, joint position sense, cervical muscle strength, cross-sectional area of selected cervical extensors and posture. Sensory measures included pressure pain thresholds (PPTs) and thermal pain thresholds (TPTs). PPTs were measured over the forehead, upper neck and at a remote site (tibialis anterior). TPTs were measured over the upper neck. Results: Cluster analysis, based on the three musculoskeletal variables aligned previously with cervicogenic headache, divided headache subjects into two groups; cluster 1 (n = 57), cluster 2 (n = 50). There was significantly reduced cervical extension, axial rotation, rotation in neck flexion and lateral flexion in the headache clusters than the control group, and in the frequency of symptomatic joint dysfunction (C0-1 – C7-T1) (all p < 0.05). Subjects in cluster 1 had significantly reduced range of cervical extension and axial rotation and frequency of symptomatic joint dysfunction (C1-2 and C7-T1) compared to those in cluster 2 and controls (all p < 0.05). More subjects in cluster 1 had headaches ≥ 15 days per month and histories of head/neck trauma (both p < 0.05). Most cervicogenic headaches were grouped in cluster 1, but musculoskeletal dysfunction was also found in headaches classifiable as migraine or tension-type headache. The analysis of subjects with single headaches revealed no significant differences between the headache groups (migraine, tension-type, cervicogenic and unclassifiable headaches) and controls in pressure and cold pain thresholds (all p > 0.05). Heat pain thresholds were significantly lower in the headache groups compared to controls (all p < 0.01) but there were no differences between headache types (all p > 0.05). There were no strong relationships between any headache variable and pain thresholds. Elders with headache scored lower on most SF-36 domains, higher on the GDS-S (p < 0.05) and comparably on the SOPA-35 (p > 0.05) compared to the control group. The GDS score was below the threshold value for depression. Differences in these measures were not dependent on the headache types but rather, headache frequency. Subjects with headaches ≥ 15 days/month scored lowest on SF-36 domains and highest on GDS-S questionnaire compared to those with headache < 15 days/month and controls (all p < 0.05). The mean NDI score in the subjects with headache indicated the presence of mild to moderate neck pain and disability. No strong relationships were found between well-being and headache frequency, intensity and length of headache history. The NDI score had the greatest influence on physical well-being and GDS-S score on mental well-being (p < 0.001). Conclusions: Several aspects of cervical musculoskeletal function, heat thresholds, general well being and quality of life were altered in elders with headache. Neck dysfunction was not uniquely confined to cervicogenic headache but was a generic feature of headache in the elderly. No generalized changes in pain sensitivity were present in elders with headache. Headache had a significant impact on elders’ quality of life but was not associated with depression. Neck pain was an important factor influencing function and well-being. Conservative management such as physiotherapy may be a safe and appropriate option for elders with headache, given its frequent association with cervical musculoskeletal impairment. Further research is required for a better understanding of the neck’s role in elders’ headache.
