Life balance is a new and important concept in occupational therapy. New measurements are needed to assess and evaluate life balance and interventions aimed to achieve this concept. This article describes the test-retest reliability of three life balance measures: the Activity Calculator (AC), Activity Card Sort (ACS-NL(18-64)) and Occupational Balance Questionnaire (OBQ11-NL). Data collection took place among 50 participants with neuromuscular diseases: facioscapulohumeral dystrophy (FSHD, n = 25) or mitochondrial myopathy (MM, n = 25). The AC, the ACS-NL(18–64) and the OBQ11-NL were assessed twice with an interval of one week. Intraclass correlation coefficients (ICC-agreement) were applied to examine test-retest reliability. The ICC of the AC-average total day score was.95 (95% CI.91-.97), whereas the ICC of the weights allocated to each activity was 0.80 (95% CI.77–0.82). The ICC of the ACS-NL(18–64) percentage retained activities was 0.92 (95% CI 0.86 − 0.96) and the ICC of the importance score per activity was-.76 (95% CI. 0.68–0.89). The ICC of the OBQ11-NL total score was.76 (95% CI 0.62–0.86). All three tools showed good to excellent test-retest reliability in a sample of patients with FSHD or MM, which is promising for its use in clinical practice and research. The AC, ACS-NL(18–64) and the OBQ11-NL are promising, reliable measures of life balance in patients with neuromuscular diseases. The development of three new instruments for life balance enlarges the possibility for health professionals to measure life balance in clinical practice and research. [ABSTRACT FROM AUTHOR]

Myotonic dystrophy type 1 is a neuromuscular disorder affecting multiple organ systems and is characterized by a variety of clinical presentations. Anticipation leads to an earlier and more severe phenotype in subsequent generations. Early-onset cataract is a common initial manifestation of the late or adult-onset type of myotonic dystrophy 1. Due to its multicausal nature, early-onset cataract is often not recognized as a feature of this disease, leading to diagnostic delay resulting in consequences for successive generations, treatment and counseling. A qualitative study with semi-structured interviews was performed with purposive sampling of eight participants with myotonic dystrophy type 1 and early-onset cataract to investigate the physical and psychosocial consequences experienced due to diagnostic delay. Prior to the early-onset cataract, all participants experienced other multisystem symptoms that could have been explained by myotonic dystrophy. The diagnostic delay had severe hereditary consequences: a subsequent generation with more severely affected (grand)children was born resulting in large emotional burden for the patients. To conclude, early-onset cataract is a warning sign and ophthalmologists play a crucial role in the early detection of myotonic dystrophy type 1 by recognizing this symptom and preventing the birth of severely affected children leading to emotional and psychosocial consequences., Competing Interests: Declaration of Competing interests The authors report no competing interests., (Copyright © 2022.
