Pain during the active phase of the first stage of labour is one of the main challenges in childbirth. Effective pain management is essential to maintain maternal comfort and calmness throughout labour. One non-pharmacological intervention that can be applied is the use of the birthball technique, which aids in accelerating labour progression and reducing pain intensity through active movement and ergonomic positioning. This case study aimed to examine the impact of the birthball technique on labour pain intensity during the active phase of the first stage of labour. A quantitative approach with a one-shot case study design was used, where pain intensity was measured once after the intervention without a control group. The intervention involved two sessions using the birthball technique, and pain intensity was assessed using the Numeric Rating Scale (NRS) after each session. The results indicated a decrease in labour pain intensity following the birthball intervention. Mothers reported increased comfort and reduced pain compared to their condition before the intervention. The use of the birthball technique was effective in lowering pain levels during the active phase of the first stage of labour and in enhancing maternal comfort. This intervention is a viable option for non-pharmacological pain management in midwifery care. Keywords: Midwifery Care, Birth-ball, Labour Pain, Active First Phase.
