Home exercises started with radiotherapy preserved swallowing and neck movement in head and neck cancer

Design

Randomised controlled trial

Population

24 patients receiving radiotherapy for head and neck cancer

Primary outcome

Swallowing quality of life, posture, cervical range of motion, lymphoedema

Effect

SWAL-QOL maintained vs declined in controls (P < .001); no difference in facial oedema

This randomised trial at a university hospital allocated 24 patients starting radiotherapy for head and neck cancer to a home programme of swallowing, posture, range-of-motion and strengthening exercises, or to standard care.

Swallowing-related quality of life was maintained in the exercise group but fell significantly in controls. The exercise group also preserved lateral neck tilt and cervical flexion, extension, rotation and lateral flexion. Facial oedema rose slightly in both groups with no difference, so the exercises did not worsen lymphoedema. Adherence was high.

The trial is tiny, and most results are reported as P values. But it agrees with a wider body of work suggesting prophylactic swallowing exercise protects function, and the intervention is cheap, home-based and safe. Starting exercises before function is lost, rather than referring once dysphagia develops, is the change it supports.

• Start swallowing and neck exercises at the beginning of radiotherapy, not after dysphagia appears
• Give a written or video home programme and check adherence at each review
• Include neck range-of-motion and posture work, not only swallowing
• Reassure patients that the exercises did not worsen facial oedema
• Involve a speech and swallow therapist early where one is available

Why it matters

It moves rehabilitation from after the damage to alongside the treatment.

Don't overread it

Only 24 patients, with outcomes reported mainly as P values; the size of the benefit is not known.

The statistics, in plain English

A very small trial can detect only large effects and is vulnerable to chance imbalances between groups. The direction matches other studies, but the effect size needs a larger trial.
