## 3 Results
Taking into account all of the previously mentioned components, a Motion Activity Index (MAI) was calculated for both the left and right sides and collectively for the left, right, and central segments, as shown in Table 3. Generally, it was observed that the MWE group exhibited a higher level of activity compared to the AWE group (36.6% vs. 25.5%, \(p=0.019\)). The movements of the MWE employees were predominantly symmetrical (\(p>0.05\)), with a minor tendency towards more activity on the right side. In contrast, the AWE group demonstrated asymmetrical movements, with a notably higher activity level on the right side (\(p=0.043\)). The study's comparison between the well-being of its participants and benchmark scores for average well-being and ill-health populations (referenced in Table 4) revealed no significant mental health issues, except for complaints related to somatic symptoms. These issues were predominantly associated with persistent fatigue, characterised by sensations of poor health, weariness, weakness, sickness, recurring headaches, and feeling overwhelmed. \begin{table}

Table 2: The results of linear accelerations (in degrees per second squared) for the machining workstation employees (MWEs) and assembly workstation employees (AWEs). The median +/ – IQR of the maximum values of acceleration in the particular joints for the left (LT) or right (RT) side or a central segment is accompanied by the significant \(p\)-values of test statistics between groups (p1) or between sides within groups (p2, p3). \begin{table}

Table 3: The results of normalised motion activity indexes (denoted by the per cent sign) for the machining workstation employees (MWEs) and assembly workstation employees (AWEs). The median +/ – IQR of the maximum values of acceleration in the particular joints for the left (LT) or right (RT) side or a central segment is accompanied by the significant \(p\)-values of test statistics between groups (p1) or between sides within groups (p2, p3). The findings indicate that repetitive motions required in manufacturing tasks, often involving asymmetrical body positions, detrimentally affect physical health, leading to fatigue and exhaustion. Furthermore, approximately 74% of the participants in the study scored higher than the average value of the \"healthy sample,\" indicating substantial concerns regarding somatic well-being. This includes frequent experiences of exhaustion, weakness, tiredness, and various bodily pains.
