Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Change in Western Ontario Rotator Cuff (WORC)
Prazo: Change from baseline to 3 months post-intervention

The WORC Index is self-administered, and includes a 5 different domains (physical symptoms, sports and recreation, work, social function, and emotions). Each question uses a visual analog scale (VAS) representing a 100-point scale ranging from 0 to 100. The maximum score is 2100 (worst possible symptoms). Zero (0) represents no symptoms at all. The final score can also be presented as a percentage by subtracting the total from 2100, dividing by 2100, and multiplying by 100. This will give you an overall percentage. The total final WORC Index scores can, therefore, range from 0% (lowest functional status level) to 100% (highest functional status level).

The WORC Index is self-administered, and includes a 5 different domains (physical symptoms, sports and recreation, work, social function, and emotions). Each question uses a visual analog scale (VAS) representing a 100-point scale ranging from 0 to 100. The maximum score is 2100 (worst possible symptoms). Zero (0) represents no symptoms at all.

Pre-op, 6 weeks, 3, 6, 12 and 24 months
Constant-Murley Score
Prazo: Pre-Op, 3, 6, 12 and 24 months

The Constant-Murley Score is a validated assessment of pain and shoulder functionality. The Constant Score is divided into 4 subscales: pain (15 points; VAS score range of 0-15), activities of daily living (20 points; range 0=worst, 5=best), strength (25 points; 1 point given per 0.5 kg of weights raised), and range of motion - forward flexion, external rotation, abduction and internal rotation of the shoulder (40 points; range 0=worst, 10=best). The higher the score, the higher the quality of function.

Pre-Op, 3, 6, 12 and 24 months
Subjective Shoulder Value (SSV) score
Prazo: Pre-Op, 6 weeks, 3, 12 and 24 months

The SSV is defined as a patient's subjective shoulder assessment expressed as a percentage of an entirely normal shoulder, which would score 100% (0% to 100% scale with 100% being normal).

Pre-Op, 6 weeks, 3, 12 and 24 months
EuroQol 5 Dimension 5 Level (EQ-5D-5L) VAS & index scores
Prazo: Pre-Op, 3 and 6 weeks, 3, 6, 12 and 24 months

To assess the subject's health state. The EQ-5D-5L is composed of the EQ- 5D-5L descriptive system and the EQ Visual Analogue scale (EQ VAS).

The descriptive system comprises 5 dimensions (mobility, self care, usual activities, pain/discomfort, anxiety/depression). Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. Responses are coded as single-digit numbers expressing the severity level selected in each dimension. For instance, 'slight problems' (e.g. 'I have slight problems in walking about') is always coded as '2'. The digits for the five dimensions are combined in a 5-digit code. The EQ- 5D-5L index value is derived by using the vendor supplied calculator to convert each 5-digit EQ- 5D-5L profile.

The EQ VAS corresponds to a 20 cm vertical, visual analogue scale ranging from 'the best health you can imagine' to 'the worst health you can imagine'.

A higher number is a better outcome.
