Mapping a measure of physical ability for persons with long-term musculoskeletal pain to the ICF and ICF Core Sets.

BACKGROUND: Test Instrument for Profile of Physical Ability (TIPPA) is used in the Swedish sickness certification process for patients with long-term musculoskeletal pain. The aim was to explore the content of TIPPA in the context of work-ability assessments. METHODS: The full protocol of TIPPA was linked to the in relation to the International Classification of Functioning, Disability and Health (ICF) and evaluated in relation to the ICF Core Sets for Chronic Widespread Pain (CWP). RESULTS: Twenty-two unique meaningful concepts were identified in TIPPA. Eighteen of those could be linked to ICF, yielding 27 third-level ICF-categories. Ten of these categories fitted the domains of 'body function', 16 were 'activity and participation', while one was related to 'environmental factors'. Perspective and aim varied between the parts of the test. When assessed against Brief ICF Core Set for CWP, TIPPA covered three of nine 'body function' categories and 2 out of 10 'activity and participation' categories. The coverage of the subgroup 'activity' was two out of five. TIPPA did not cover three categories, i.e. 'd175 solving problems', 'd230 carrying out daily routine' and 'd240 handling stress and other psychological demands', in the subgroup of 'activity'. CONCLUSIONS: TIPPA could be a useful measure for the assessment of physical ability. However, additional condition-specific items/measures are required to obtain full coverage of core aspects of functioning and disability in a comprehensive work-ability assessment for patients with long-term musculoskeletal pain.

Measuring Sedentary Behavior by Means of Muscular Activity and Accelerometry.

Sedentary Behavior (SB) is among the most frequent human behaviors and is associated with a plethora of serious chronic lifestyle diseases as well as premature death. Office workers in particular are at an increased risk due to their extensive amounts of occupational SB. However, we still lack an objective method to measure SB consistent with its definition. We have therefore developed a new measurement system based on muscular activity and accelerometry. The primary aim of the present study was to calibrate the new-developed 8-CH-EMG+ for measuring occupational SB against an indirect calorimeter during typical desk-based office work activities. In total, 25 volunteers performed nine office tasks at three typical workplaces. Minute-by-minute posture and activity classification was performed using subsequent decision trees developed with artificial intelligence data processing techniques. The 8-CH-EMG+ successfully identified all sitting episodes (AUC = 1.0). Furthermore, depending on the number of electromyography channels included, the device has a sensitivity of 83⁻98% and 74⁻98% to detect SB and active sitting (AUC = 0.85⁻0.91). The 8-CH-EMG+ advances the field of objective SB measurements by combining accelerometry with muscular activity. Future field studies should consider the use of EMG sensors to record SB in line with its definition.
