- Design
- Randomised controlled trial, single academic centre (registered)
- Population
- 24 patients receiving radiotherapy for head and neck cancer (12 exercise, 12 standard care)
- Primary outcome
- Swallowing quality of life, neck posture and cervical range of motion, facial oedema
- Effect
- Swallowing quality of life maintained with exercise and worse in controls (P < .001); effect sizes not given
This randomised trial in 24 patients having radiotherapy for head and neck cancer compared a prophylactic home programme of swallowing, posture, range-of-motion and strengthening exercises (12 patients) with standard care (12 patients).
Swallowing quality of life was maintained in the exercise group and fell significantly in controls (P < .001). Neck lateral tilt and cervical flexion, extension, rotation and lateral flexion were better preserved with exercise. Facial oedema measures rose slightly in both groups without a significant difference, which the authors take as evidence of safety. Adherence was reported as high.
With 24 patients, effect sizes are not reported in the abstract, and the study is a pilot in scale. It does support offering structured exercises early, which carries little downside.
- Offer swallowing and neck exercises from the start of radiotherapy, rather than after problems appear.
- Involve a speech and language therapist and physiotherapist where available.
- Check lymphoedema and facial swelling at each review.
- Record adherence, since benefit depends on doing the exercises.
Why it matters
Swallowing decline during radiotherapy is common, and prevention is cheaper than rehabilitation.
Don't overread it
A 24-patient single-centre trial with self-reported quality of life; it does not show that exercises prevent long-term feeding-tube dependence.
The statistics, in plain English
With 12 patients per arm, a very small P value can still come from a few outliers, and no confidence intervals or effect sizes were given in the abstract. Treat it as encouraging pilot evidence.
