Active range of motion in the cervical spine increases after spinal manipulation (toggle recoil).

BACKGROUND: It has generally been assumed that spinal manipulation has the biomechanical effect of increasing spinal range of motion. Past research has shown that there are likely no lasting changes to passive range of motion, and it is unclear whether there is an increase in active range of motion after manipulation. OBJECTIVE: To study changes in active cervical range of motion after spinal manipulation of the cervical spine. DESIGN: A double-blind randomized controlled trial at the outpatient clinic Phillip Chiropractic Research Centre, RMIT University, Melbourne, Australia. METHODS: One hundred five patients with cervicogenic headache were randomized into 2 groups. After a baseline observation period, Group 2 received manipulation (toggle recoil) to the cervical spine, whereas Group 1 received sham manipulation. In the next trial phase, Group 1 received manipulation, whereas Group 2 received no treatment. This was followed by the final trial phase, in which Group 2 received sham manipulation and Group 1 received no treatment. After each trial phase, active range of cervical motion was measured with a strap-on head goniometer by 2 blinded examiners. RESULTS: After receiving spinal manipulation, active range of motion in the cervical spine increased significantly (P < .0006) in Group 2 compared with Group 1, and this difference between the treatment groups disappeared after the third trial phase in which Group 1 also received manipulation, as expected. CONCLUSION: Spinal manipulation of the cervical spine increases active range of motion.

The effect of manipulation (toggle recoil technique) for headaches with upper cervical joint dysfunction: a pilot study.

OBJECTIVE: The objective of this pilot study was to investigate the effect of spinal manipulation for the relief of chronic headache of cervical origin, utilizing a specific technique, toggle recoil, to treat the two upper cervical vertebrae. This study will help delineate the design for a future, larger study. DESIGN: Twenty-six patients were accepted for a continuous time series analysis (6 wk) design. SETTING: Chiropractic outpatient research clinic. PATIENTS: The patients--16 females (average age 42.1 yr, SD 11.03) and 10 males (average age 52.1 yr, SD 10.69) all had chronic headaches (> 3 mo) with upper cervical joint dysfunction. INTERVENTION: All the patients received four upper cervical toggle recoil adjustments over a 2-wk period. MAIN OUTCOME MEASURES: Standardized headache history, daily questionnaires for the duration of the trial, measuring; frequency; and severity of the headache, plain film with dynamic spinal radiographs and motion palpation. RESULTS: The results indicate statistically significant outcomes (p < .001) that indicate changes in headache frequency, duration and severity in all but two of the patients. The overall duration of headaches decreased from 110 hr pretreatment to 25 hr posttreatment, a decrease of 77%. The overall score for severity dropped from 55 to 22--a 60% improvement in perceived pain. The frequency of headaches over a 2-wk period dropped from 18 to 7, an improvement of 62%. CONCLUSIONS: Since the results of this pilot study were not adequately controlled they cannot be seen as proof supporting the clinical efficacy of manipulation for chronic headaches. However, as a group for duration, severity and frequency all measures were significant. These findings would suggest that further study of upper cervical manipulation for the treatment of chronic headaches with upper cervical joint dysfunction in a randomized, controlled clinical trial is needed.

The impact of pulmonary infections on the survival of lung cancer patients.

To determine the impact of pulmonary infections on survival in patients with lung cancer, a retrospective review of the records of 121 such patients treated at Howard University Hospital in Washington, DC, was done. There were 77 men and 44 women; 118 were black. The mean age was 63.5 years. Forty-three patients had squamous cell carcinoma, 31 had adenocarcinoma, 18 had large cell carcinoma, 19 had small cell carcinoma, and ten were unclassified. The stages were as follows: two patients in Stage 0, 15 in Stage I, seven in Stage II, 45 in Stage III, and 44 in Stage IV. Eight patients could not be staged at diagnosis. Eighty-five patients (70%) had documented infections; 37 had single episodes; and 48 had more than one. The five most common organisms recovered were alpha/gamma streptococci, Staphylococcus aureus, Klebsiella pneumoniae, Enterobacter aerogenes, and Pseudomonas aeruginosa. The median survival of all infected patients was 4.2 months which was significantly shorter than that of uninfected patients who had a median survival of 12.9 months (P less than 0.05). When Stage III patients were analyzed separately, infected patients lived a median of 5.8 months and uninfected patients, 13.4 months (P less than 0.05). This study indicated that pulmonary infections frequently occur in patients with lung cancer and suggested that they may adversely affect survival.
